1. Don’t skip breakfast
2. The key to a healthy diet
3. Eat more fish
4. No more than 6g of salt a day for adults
5. Cut down on saturated fat and sugar
6. Eat lots of fruit and veg
7. Base your meals on starchy carbohydrates
8. The hazards of an unhealthy diet

A. Eat the right amount of calories for how active you are, so that you balance the energy you consume with the energy you use. If you eat or drink too much, you’ll put on weight. If you eat and drink too little, you’ll lose weight. Eat a wide range of foods to ensure that you’re getting a balanced diet and that your body is receiving all the nutrients it needs. It is recommended that men have around 2,500 calories a day. Women should have around 2,000 calories a day. Most adults are eating more calories than they need, and should eat fewer calories.

B. They include potatoes, bread, rice, pasta and cereals. Choose wholegrain varieties (or eat potatoes with their skins on) when you can: they contain more fibre, and can help you feel full for longer. Most of us should eat more starchy foods: try to include at least one starchy food with each main meal. Some people think starchy foods are fattening, but gram for gram the carbohydrate they contain provides fewer than half the calories of fat. Keep an eye on the fats you add when you’re cooking or serving these types of foods because that’s what increases the calorie content, for example oil on chips, butter on bread and creamy sauces on pasta.

C. It’s recommended that we eat at least five portions of a variety of fruit and veg every day. It’s easier than it sounds. Why not chop a banana over your breakfast cereal, or swap your usual mid-morning snack for a piece of fresh fruit? Unsweetened 100% fruit juice, vegetable juice and smoothies can only ever count as a maximum of one portion of your 5 a day. For example, if you have two glasses of fruit juice and a smoothie in one day, that still only counts as one portion.

D. Fish is a good source of protein and contains many vitamins and minerals. Aim to eat at least two portions of fish a week, including at least one portion of oily fish. Oily fish contains omega-3 fats, which may help to prevent heart disease. If you regularly eat a lot of fish, try to choose as wide a variety as possible. You can choose from fresh, frozen and canned: but remember that canned and smoked fish can be high in salt.

E. We all need some fat in our diet, but it’s important to pay attention to the amount and type of fat we’re eating. There are two main types of fat: saturated and unsaturated. Too much saturated fat can increase the amount of cholesterol in the blood, which increases your risk of developing heart disease. The average man should have no more than 30g saturated fat a day. The average woman should have no more than 20g saturated fat a day, and children should have less than adults.

F. Eating too much salt can raise your blood pressure. People with high blood pressure are more likely to develop heart disease or have a stroke. Even if you don’t add salt to your food, you may still be eating too much. About three-quarters of the salt we eat is already in the food we buy, such as breakfast cereals, soups, breads and sauces. Use food labels to help you cut down. More than 1.5g of salt per 100g means the food is high in salt. Adults and children over 11 should eat no more than 6g of salt (about a teaspoonful) a day. Younger children should have even less.

G. Eating a healthy, balanced diet plays an essential role in maintaining a healthy weight, which is an important part of overall good health. Being overweight or obese can lead to health conditions such as type 2 diabetes, certain cancers, heart disease and stroke. Being underweight could also affect your health.

Nutrients your body needs егэ

If your diet is perfect, you can stop reading right now. This story is for people who occasionally hang out with foods best described as bad nutritional influences. That’s because even dietary troublemakers have redeeming qualities and you can find surprising sources of nutrients everywhere.

That doesn’t mean your whole diet should—or even can—be filled with foods that lean so heavily into the unhealthy. You need to limit the foods mentioned below. And for good health and weight maintenance, fill up on nutritious whole foods and plenty of plants.

But for the sake of your happiness or sanity, sometimes you need to stray—even momentarily. So, the following list of surprising sources of nutrients isn’t meant to absolve your dietary indiscretions. Instead, use it to help you pick a pleasure with at least a sliver of a nutritional silver lining.

Dark Chocolate Could be Your Choice for Unexpected Nutrition

Nutrients your body needs егэ

This is probably the most well-known example of important nutrients in a delicious disguise. But let’s get something straight—this isn’t a blanket statement about all chocolate. Only the dark variety (cocoa—the unsweetened powder, not the drink—content at 50 percent or above) brings the hidden nutrient payload.

White chocolate is basically sugar and fat—without any actual cocoa in it. Milk chocolate is ubiquitous, creamy, delicious, and lacking many cocoa solids, which almost eliminates any nutritional upside whatsoever.

Dark chocolate contains more of the actual source material—the pods of the cacoa plant—which makes it more bitter and nutritious. That’s because this dark delight retains some soluble fiber, beneficial fatty acids, minerals, and small amounts of caffeine.

The phytonutrients in dark chocolate are also a big part of the surprising nutritional profile. Chocolate’s bio-active plant compounds have the ability to provide antioxidant support. And cocoa’s profile of phytonutrients—in this case, flavonols, catechins, and polyphenols—compares favorably to some berries.

That doesn’t mean you should permanently replace your afternoon handful of blueberries with a bar of dark chocolate. Even though it’s a surprising source of nutrients, dark chocolate is an unsurprising source of calories and fat. Any nutrient density is unfortunately balanced with the density of calories. So, eat dark chocolate in moderation—an ounce (28 grams) here and there won’t hurt. And you now have the information to back up your decadent decision.

What Nutrients are Hiding in Dark Chocolate?

  • Iron
  • Copper
  • Magnesium
  • Zinc
  • Phosphorus
  • Manganese
  • Potassium
  • Selenium
  • Flavonols
  • Fiber

The Shocking Nutritional Power of Potatoes

These tubers get a bad reputation. But why do potatoes have to be so delicious when fried and salted? Without the unhealthy preparation, potatoes absolutely qualify as a surprising source of nutrients.

Potatoes are just plants, after all—starchy nightshades grown underground to be exact. That’s the same family as tomatoes, peppers, and eggplant. And potatoes share vitamin and mineral content with their conventionally healthy cousins.

The white or gold varieties of potato—sweet potatoes are different and often considered healthier anyway—have vitamin C, potassium, vitamin B6, and certain polyphenols. Since they’re mostly carbohydrates, potatoes also contain a small amount fiber. What is there mostly takes the form of resistant starch and insoluble fiber.

A majority of potatoes’ helpful nutrients aren’t hiding deep inside. They’re right on the surface, in the skin. So, when you cook potatoes, wash them thoroughly to remove dirt, but don’t peel them. You’re throwing a significant percentage of the nutrition in the garbage or compost.

There are plenty of nutrients to make potatoes worthwhile parts of your plate. And they are a staple food around the world. But overeating these starchy vegetables can be detrimental to weight management. That’s partly because plain potatoes are high glycemic and fairly calorie dense.

So, when potatoes are on the menu, make sure to pay attention to preparation (leave the peel) and cooking method (baked or boiled—not fried or cooked without excess fat). To lower the glycemic impact of potatoes, eat them as part of an entire meal (with protein, added fiber, and fats) to help slow the rate of digestion. And know when you dig in, you’re doing something surprisingly good for your health.

What Nutrients are Hiding in Potatoes?

  • Insoluble fiber
  • Resistant starch
  • Potassium
  • Magnesium
  • Vitamin C
  • Vitamin B6
  • Vitamin B9 (folate)
  • Choline
  • Antioxidants from various polyphenols (including catechin and lutein)

Looking for a Surprising Source of Nutrients? Say Cheese!

Nutrients your body needs егэ

Cheese can be gooey, melty, creamy, or delightfully funky. It’s also full of saturated fat, calories, and quite a bit of salt. That’s not all that awaits cheese lovers, though.

The delectable dairy treat sports a bevy of beneficial nutrients to help balance some of the negatives. It has protein, a variety of essential minerals (calcium, zinc, and phosphorous), and vitamins A, B2, and B12. Depending on the milk source, cheeses can even contain conjugated linoleic acid, vitamin K2, good bacteria, omega-3s, and other fatty acids.

And you have your choice of different cheeses. If you’ve visited any grocery store lately, you know the variety of cheeses is staggering. Each type of cheese offers a different level of healthfulness, too.

It’s time to slice up the nutritional goodness for a few common varieties of cheese:

  • Cheddar: A popular addition to a variety of dishes—or simply delicious on top of crackers—this cheese, per ounce (28 grams), has: 115 calories, seven grams of protein, 20 percent of your recommended daily intake (RDI) of calcium, and some vitamin K2.
  • Blue Cheese: A rich cheese with veins of mold that has about 100 calories per ounce, six grams of protein, and a third of your RDI of calcium.
  • Feta: Crumbles of this salty cheese can give your salad a big boost of flavor, protein, and calcium without too many calories—80 per ounce, six grams of protein, and 10 percent of your daily calcium.
  • Mozzarella: This lower fat, lower sodium cheese is also lower calorie—about 85 per ounce—but still has plenty of protein (six grams) and calcium (14 percent of your daily recommendation in just an ounce).
  • Parmesan: A hard cheese that’s great as a topping contains about 110 calories per ounce, 10 grams of protein, 34 percent of your RDI of calcium, and about 30 percent of your recommended intake of phosphorous.
  • Swiss: Don’t let the holes fool you, there’s still plenty of protein (eight grams), not a lot of sodium, and very few carb (less than a gram) in this popular cheese—which also has about 111 calories and a quarter of daily calcium intake in an ounce.

All the fat, calories, and sodium necessitates a moderate approach to cheese consumption. And it’s obviously a no-no for those avoiding dairy for any reason. But if cheese melts your willpower, don’t fear too much. It’s still a surprising source of nutrients you need.

What Nutrients are Hiding in Cheese?

  • Protein
  • Vitamin A
  • Vitamin B2
  • Vitamin B12
  • Vitamin K
  • Calcium
  • Zinc
  • Phosphorous
  • Fatty acids—like palmitoleate, conjugated linoleic acid (CLA), and omega 3s
  • Good bacteria

Crack Open the Cold, Hard Facts About Hidden Nutrients in Beer

Moderation is the best mode when considering alcohol as part of your lifestyle. And avoiding it altogether is the only path that works for some. But if you’re going to pour yourself something stronger than water, beer is an unexpectedly good option.

Imbibing moderate amount of any alcohol has been found to have health benefits. Wine usually drinks up a lot of the publicity about healthy alcoholic beverages. But don’t sleep on the surprising nutrients lurking just below the foam of your sudsy lager or ale (especially those that haven’t filtered out all the grain proteins, hop material, and yeast from solution).

The B vitamins, soluble fiber, and very small amounts of various essential minerals help balance out some of the negatives brought on by beer’s high calories and carb count. You couldn’t, and shouldn’t, turn to beer for any significant portion of your nutritional needs, though.

There is one interesting and beneficial organic compound that is hard to find in other sources—xanthohumol. This bioflavonoid (a special kind of polyphenol and phytonutrient) comes from the hops used to bitter and flavor beer.

Research on this emerging compound isn’t robust, yet. But early results are promising. It’s found that your body may like xanthohumol because of its antioxidant properties, which means it helps fight free radicals. The most effective doses of this bioflavonoid are much higher than what you’d get in even the hoppiest beer, though.

So, if you don’t drink alcohol, that’s probably a good decision for your overall health. Those that do choose to tip one back every once in a while—always responsibly, moderately, and legally—can find surprising nutritional content in their favorite pint.

What Nutrients are Hiding in Beer?

  • Soluble fiber
  • B vitamins
  • Silicon
  • Potassium
  • Calcium
  • Iron
  • Magnesium
  • Phosphorous
  • Fluoride
  • Copper
  • Selenium
  • Manganese
  • Zinc
  • Antioxidants from phytonutrients in the ingredients (barley and hops)
  • Xanthohumol

Surprises are Good—Sometimes

Knowing where to find surprising sources of nutrients is a good way to pick and explain away your guilty pleasures. You might even impress your friends with these fun facts. Again, though, these foods shouldn’t make up the bulk of your diet.

You can feel good about finding buried nutritional treasure in seemingly irredeemable foods and beverages. But remember there are more obvious sources of important nutrients that should be the focus of your meal planning.

Vegetables, fruits, healthy fats, lean protein, and whole grains might not offer the rush of the foods above. But they’re the foundation of the healthy diet that allows you to occasionally opt for something a little more fun—with a few hidden nutrient surprises, too.

Essential nutrients - Dr. Axe

With so much information circulating out there about nutrition, it can be challenging to make sure you’re getting the nutrients you need each day. In fact, with some sources listing as many as 90 essential nutrients, following a balanced diet can quickly become overwhelming.

However, getting all the nutrients you need doesn’t have to be complicated. In fact, by just being mindful about a few specific nutrients, eating a healthy diet full of nutrient-dense foods can be pretty simple.

Breaking it down into essential versus nonessential nutrients can help simplify and streamline your diet, making it easier than ever to achieve better health. But what are those nutrients, and what do nutrients do, anyway? Let’s take a look at the 11 essential nutrients your body needs, why and how to obtain them.

What Are Nutrients?

According to the dictionary, the official nutrients definition is “a substance that provides nourishment essential for growth and the maintenance of life.”

This encompasses the broad spectrum of micronutrients, healthy fats, amino acids and other substances that your body needs to function, survive and thrive. Most of these are obtained through the things you eat, drink or supplement in your diet.

However, this nutrients definition doesn’t differentiate between essential and nonessential nutrients.

While there are thousands of specific nutrients, each with its own unique benefits and functions, there are a few specific nutrients that you should be especially mindful about incorporating into your day. And although there are technically six essential nutrients, there are certain healthy fats, vitamins and minerals that you should be sure to include in your diet as well.

Essential Nutrients vs. Nonessential Nutrients

So what exactly distinguishes an essential nutrient from a nonessential nutrient?

There are six essential nutrients found in the body, including carbohydrates, fats, proteins, water, vitamins and minerals — with proteins, carbs and fats classified as macronutrients. These are the main classes of nutrients, which can further be broken down into specific micronutrients that are especially important for health.

Essential nutrients cannot be produced by the body and must be obtained through other means while many nonessential nutrients can be both synthesized and absorbed from food.

Cholesterol, for example, is needed to produce hormones and maintain the cell membrane, but it can be either obtained from food or produced in the body.

Benefits

Meeting your essential nutrient needs can come with major benefits in terms of your health.

In fact, these nutrients are called “essential” for a reason. Without these crucial nutrients, vitamins and minerals, your body would not be able to function properly.

Meeting your potassium needs, for example, helps your heart pump blood throughout your body, while calcium and vitamin D keep your skeletal framework strong and sturdy.

Other important benefits that come with getting enough nutrients include improving your immune system, building muscle, keeping your heart healthy and staying hydrated — as well as sustaining life and keeping your body working efficiently.

11 Essential Nutrients

1. Carbohydrates

Despite being demonized as “unhealthy” or “fattening,” carbohydrates are critical to the function of your body. Carbohydrates are broken down into glucose, which is the primary source of fuel for your body and brain.

Not only do they provide energy for the body, but they also help stabilize blood sugar levels and preserve muscle mass by preventing the breakdown of proteins for energy.

Plus, some of the world’s healthiest foods fall into the category of carbohydrates. Fruits and vegetables, for instance, are incredibly nutrient-dense and loaded with important vitamins, minerals and antioxidants.

Even on a low-carb or ketogenic diet, you’re still taking in a few grams of carbohydrates here and there, making healthy carbs an important part of any diet.

Complex carbohydrates take longer to break down, which can help you feel fuller for longer and keep blood sugar levels regular.

Whole grains, vegetables and fruits are a few examples of healthy complex carbohydrates that can fuel your body and supply you with a megadose of nutrients.

2. Protein

It’s no secret that protein is critical to good health. From forming muscle to creating new enzymes and hormones, getting enough protein in your diet is key.

Proteins are made up of building blocks called amino acids, which are composed of even smaller units called peptides.

There are 20 types of amino acids, all of which are important. However, nine of these are considered essential amino acids because they can’t be produced by your body.

The nine essential amino acids include:

  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine

While animal proteins provide adequate amounts of all essential amino acids, plant-based proteins are typically lacking in one or more.

The best way to ensure adequate protein intake is to include a variety of protein foods in your diet, such as meat, eggs, dairy, nuts and beans.

3. Fat

Much like carbohydrates, dietary fat has earned an undeservedly bad reputation because of its association with body fat.

Fat is an essential nutrient that provides energy, boosts the absorption of certain vitamins and helps protect your organs from damage.

Some types of fat are better than others, however. Trans fats, for example, are a type of fat found in processed foods, baked goods and shortening. This type of fat has been shown to significantly increase the risk of heart disease and should be avoided at all costs.

Unsaturated fats, on the other hand, can actually help protect the heart and aid in the prevention of heart disease.

Healthy sources of fat include nuts, avocados, salmon, olive oil, flaxseed and nut butters.

Including a few servings of these foods per day can help provide the fats your body needs and protect against disease.

4. Water

The human body can survive for long periods of time without food. In fact, there have been case studies reporting on some extreme cases of people who have successfully gone without eating for 382 days under medical supervision with no negative side effects. Of course, I’d never recommend such extreme fasting — I simply point this out to highlight the importance of water.

While you may be able to go without food for quite a while, even just a few days without water can be detrimental.

Water accounts for a pretty big portion of the body, making up somewhere between 55 percent to 75 percent of your body mass.

It plays an essential role in waste removal, digestion and temperature regulation and makes up a core component of every cell in your body.

Dehydration can lead to symptoms like dry skin, dizziness, fatigue, a rapid heartbeat and even death if left untreated.

In addition to the things that you drink, you also take in water through the foods that you eat as well. Fruits and vegetables, in particular, tend to have a higher water content and can help keep you hydrated.

5. Vitamins

You’ve likely heard all about the importance of vitamins like folate, vitamin C and vitamin A, among others, so it should come as no surprise that vitamins make the list of essential nutrients.

There are many different types of vitamins, each with its own specific function and role in the body, but all equally vital for maintaining optimal health.

Vitamin A, for instance, is critical for the health of your eyes and skin, while vitamin K builds strong bones and is involved in blood clotting.

There may be minute differences in the amounts of specific vitamins for men versus women, but in general, the essential vitamins that your body needs are:

  • Vitamin A
  • Vitamin C
  • Vitamin D
  • Vitamin E
  • Vitamin K
  • B vitamins, including thiamine, riboflavin, folic acid and vitamin B12

The best way to get in all of these vitamins is to eat a healthy and balanced diet with plenty of vegetables and fruits. A multivitamin may also be useful to help fill in the gaps if you have a restrictive diet.

Essential nutrients - Dr. Axe

6. Minerals

Much like vitamins, minerals are also important for helping your body function properly and stay healthy, and each comes with its own specific role.

Iron, for example, is key to the production of red blood cells, phosphorus strengthens the bones and teeth, and magnesium is a crucial component of more than 300 reactions in the body.

The minerals that your body needs include:

  • Sodium
  • Iron
  • Potassium
  • Calcium
  • Chloride
  • Magnesium
  • Phosphorus
  • Trace minerals

These can all be obtained through food, so eating a nutritious diet can prevent deficiencies and make sure you’re getting the minerals that you need.

7. Calcium

You probably know calcium as the most important nutrient for bone health, and that’s true. Although there are several nutrients that are key to building strong bones, over 99 percent of the body’s calcium is found in the bones and teeth.

However, that’s not all calcium is good for. Calcium is also involved in muscle contractions, nerve function and the movement of blood throughout the body.

Calcium is found naturally in dairy products, leafy greens, white beans, and certain types of fish like sardines and salmon. Including these foods in your diet is the easiest way to ensure you’re meeting your daily calcium requirements.

8. Sodium

Although sodium receives a lot of negative attention for its association with high blood pressure, it’s actually incredibly important to health.

Sodium regulates fluid balance and blood volume while also keeping your nerves and muscles working correctly.

Of course, sodium should be included in moderation as excessive amounts can lead to high blood pressure in some people.

The most recent Dietary Guidelines for Americans recommend limiting sodium intake to less than 2,300 milligrams per day, which equates to about one teaspoon of salt.

Sodium is found naturally in many foods, including seeds, nuts, vegetables, meats, grains and legumes. Intake of high-sodium foods like frozen and ultra-processed foods, salty snacks, and canned meats with added salt should be minimized.

9. Potassium

Potassium is an essential electrolyte that helps maintain fluid balance and blood pressure. It also is necessary for muscle contractions, heart health and regulating the pH level of your blood to prevent it from becoming too acidic.

While most people instantly associate potassium with bananas, potassium is actually found in a wide variety of other vegetables and fruits as well.

Spinach, tomatoes, potatoes, avocados, salmon and sweet potatoes are all other excellent sources of potassium.

10. Omega-3 Fatty Acids

From optimizing brain health to preventing heart disease, omega-3 fatty acids are a vital component of many aspects of health.

Omega-3 fatty acids are a type of polyunsaturated fat that are considered an essential fatty acid. This means that, unlike other types of fatty acids, your body can’t synthesize omega-3 fats and needs to obtain them from food.

Varieties of fatty fish, such as salmon, mackerel and sardines, are the best source of omega-3 fatty acids. These contain the active forms of omega-3 fats that can be easily used by the body.

Some plant foods, such as chia seeds, flax and walnuts, also contain omega-3s. However, they contain a form of omega-3 fatty acid that is converted only in small amounts to the more active forms.

You should include one to two servings of fish in your diet each week to help meet your omega-3 fatty acid needs. Otherwise, consider taking a fish oil or algae supplement to get some omega-3s into your day.

11. Vitamin D

Also known as the “sunshine vitamin,” getting enough vitamin D is incredibly important.

Vitamin D is a fat-soluble vitamin necessary for the absorption of calcium and can promote good bone health, making it an especially important vitamin for women to help prevent osteoporosis.

Additionally, some research shows that vitamin D could strengthen the immune system and influence muscle function.

This fat-soluble vitamin is produced in the skin as a result of sun exposure and can be obtained in small quantities through foods like mushrooms, eggs and fish.

Those who have dark skin, are obese or get limited exposure to sunlight are at a greater risk for vitamin D deficiency. For these individuals, supplementation can be beneficial to prevent deficiency.

It may seem like cramming all of these essential nutrients into your diet would take a great deal of time, effort and energy. Luckily, it’s actually much simpler than it seems to get what you need each day with minimal effort required.

Although the types and sources of nutrients were listed earlier, there’s no need to meticulously follow any specific list or guide to have a healthy diet. In fact, by simply following a diet rich in whole foods with plenty of fruits, vegetables, whole grains, lean proteins and a few servings of fish each week, you’ll be getting a hearty dose of the daily essential nutrients you need with every meal.

These foods are the most nutrient-dense and can supply a concentrated amount of micronutrients with each serving.

Although most people can get all the nutrients they need from food, if you have a restrictive diet or need an extra boost, you can also consider a multivitamin or supplementation to help meet your needs.

Interesting Facts

Deficiencies of essential nutrients have been documented for centuries, although we are just recently beginning to gain a deeper understanding of the complexities of these nutrients.

In ancient Greece, philosophers developed a concept called humoralism in which it was believed that a deficiency in one of four essential “humors,” or bodily fluids, could lead to negative effects on health.

Later on, the link between food and health began to be established. In the 18th century, scurvy was a major cause of death among British sailors. Scurvy can lead to bleeding gums, fatigue and bruising, and is caused by vitamin C deficiency.

Sailors began routinely chugging lime juice as a method to get in a concentrated dose of vitamin C and ward off scurvy.

In recent years, more and more research trials have been conducted to illustrate just how important essential nutrients are to health.

Today, as the powerful effects of nutrition come to light, the emphasis continues to switch from treatment to prevention through nutrient-rich foods and a healthy lifestyle.

Risks and Precautions

Getting your essential nutrients through whole food sources is always preferable, but there may be some cases in which supplementation is needed. However, it’s always best to consult with your doctor before starting any new supplement, especially if you have underlying health conditions.

Additionally, keep in mind that moderation is key and just because a nutrient is considered essential doesn’t necessarily mean that more is always better.

Too many carbohydrates, for example, can lead to spikes and crashes in blood sugar, while too much water can lead to a condition called water intoxication, which can be dangerous. Other vitamins and minerals like iron, potassium and vitamin A can also be dangerous as well.

Enjoy moderate amounts of all of the essential nutrients you need to achieve better health and well-being.

Final Thoughts

  • Essential nutrients are essential to health. They may come with plenty of health benefits, but most importantly, they help sustain your body and allow it to grow, develop and thrive.
  • While it may seem daunting to comb through a long list of food nutrients and their sources and functions, eating healthy and squeezing in all the essential nutrients you need doesn’t have to be challenging.
  • Eating a well-balanced, healthy diet rich in fruits, vegetables, whole grains and lean proteins is enough for most people to get all of the nutrients, vitamins and minerals that they need.

As much as exercise hits your body with a barrage of feel-good hormones, it also puts your body in a state of stress. From your gut to your heart, every cell is working hard to maintain all bodily functions while you work out. That’s why it’s so important to get proper nutrition and fuel your body with foods rich in vitamins and antioxidants. “Exercise produces stress on the body, and that increases the need for certain nutrients that the body might otherwise be able to produce enough of,” says Ashley Koff, RD, founder of The Better Nutrition Program and Espira by AVON nutritionist.

Take the amino acid, glutamine, for example. “Your body produces it, but when your body is under stress during exercise, you need more of it to repair muscle, including the digestive tract lining,” Koff says. Read on to learn what vitamins, macronutrients and amino acids are crucial for building and maintaining muscle.

11 Nutrients for Muscle Building

1. Water

You already know how important it is to drink enough H2O for replenishing fluids before, during and after a workout. But staying properly hydrated also aids digestion and nutrient absorption. “Hydration is more than just quenching thirst; it means water carries nutrients to the muscles for them to do their work,” Koff says.
Best sources: Straight from the tap, or vegetables and fruits

2. Protein

Protein is one of the most essential macronutrients for muscle growth and repair because it’s packed with amino acids that your body does and doesn’t produce. That’s why it’s important to have protein post-workout to restore these muscle-building macronutrients. “Proteins not only helps rebuild and build lean body mass, but they’re also a core part of enzymes and hormones that help communicate with the body to repair itself,” Koff says.
Best sources: Dairy, lean meats, beans and other legumes, seafood, soy and eggs

3. Calcium

Calcium does more than help build strong bones and prevent osteoporosis. Koff says the mineral is responsible for triggering muscle contraction. Muscles are comprised of two protein filaments: myosin and actin. When muscle contraction occurs, these filaments slide over each other to convert ATP (adenosine triphosphate), aka the way your body stores and uses energy. The more you exercise, the more ATP your body needs to keep your muscles moving.
Best sources: Yogurt, fortified milk and cereals, cheese, tofu and spinach

4. Magnesium

Feeling more tired than usual? A magnesium deficiency could be to blame. As one of the best de-stressing minerals, magnesium is essential for muscle relaxation and preventing cramps, Koff says. Together with calcium, magnesium works to help reduce blood pressure and promote better sleep.
Best sources: Leafy greens, beans and other legumes, squash, nuts and seeds and whole grains

5. Glutamine

You might have heard of non-essential (meaning your body can produce it) and essential (meaning your body can’t produce it) amino acids, but there are also conditionally essential amino acids. Koff says your body needs more conditionally essential amino acids, such as glutamine, during intense workouts. “Glutamine helps repair muscle tissue, including the lining of the digestive tract, especially when the body has experienced stress during high-intensity exercise, like weightlifting and HIIT,” Koff says. Glutamine is also important for maintaining gut function and boosting the immune system.
Best sources: Chicken, fish, beef, dairy, eggs and spinach, Brussel sprouts and fermented foods

6. Vitamin D

The sunshine vitamin is probably best known for ensuring strong bones, but it’s also critical for strong glutes, biceps and everything in between. Koff says, “Vitamin D is linked to healthy hormones like testosterone, which helps with muscle maintenance and growth.” A daily dose of D can also improve your mental health and help reduce anxiety. Because not that many foods are rich in vitamin D, some doctors and nutritionists recommend taking a supplement.
Best sources: Fatty fish, like salmon and sardines, fortified yogurt, milk and orange juice, mushrooms and eggs

7. Potassium

Just like calcium and magnesium, potassium is a key electrolyte in muscle contraction. But it’s also essential for carrying other nutrients to your muscles. “Potassium brings water, along with other nutrients, into muscle cells. They work in opposition to sodium,” Koff says. Potassium helps your kidneys flush out the excess sodium in your body, Koff explains. What’s more: New studies have shown that people who don’t get enough potassium are at higher risk for hypertension and heart disease.
Best sources: Bananas, squash, sweet potatoes, broccoli, chicken and salmon.

8. Carbohydrates

Contrary to what you might believe, carbs are one of the best building blocks of muscles. “They’re the key nutrient to support muscle growth and repair,” Koff says. As the best source of glycogen, carbs help fuel your workouts and rebuild muscles more effectively post-workout. Runners aren’t the only ones who can benefit from carb loading. Everyone from weightlifters to HIIT enthusiasts need to restore glycogen stores after an intense sweat session.
Best sources: Whole grains, vegetables, fruits and beans and other legumes

9. B12

Vitamin B12 (cobalamin) belongs to a set of eight B vitamins known as the vitamin B complex. But what sets B12 apart is it assists in creating red blood cells, which contain hemoglobin that binds to oxygen. “[Iron] builds red blood cells, which carry oxygen to muscle, and helps metabolize protein and fats for use in muscle building and repair,” Koff says.
Best sources: Poultry, meat, fish and dairy

10. Iron

If you want to know why Popeye was slamming down cans of spinach, it’s because the leafy green is packed with iron, a mineral that “brings oxygen to muscle tissue,” Koff says. It also helps regulate metabolism and promotes a healthy immune system. Without enough iron, your red blood cells can’t carry oxygen to your muscles and the tissues that need it.
Best sources: Leafy greens, lean beef, poultry, fish, eggs and fortified whole grains

11. Beta-Alanine

Muscle cramps are one of the most common sleep complaints. The good news: Beta-alanine, a non-essential amino acid, has been shown to help people stave off muscle cramps from doing intense workouts, says Koff. “Beta-alanine helps produce carnosine, which balances the pH in muscles and fights against lactic acid buildup that leads to fatigue and cramping,” she says. Koff also says that vitamins C and E can help combat inflammation from excessive exercise. “Vitamin C helps with muscle repair as it supports collagen production, and vitamin E helps remove free radicals produced after a workout,” Koff adds.
Best sources: Animal protein and plant-based foods, like asparagus, edamame, seaweed, turnip greens and watercress
