The U.S. federal government’s Dietary Guidelines for Americans report states that many adults lack essential nutrients, including several vitamins and minerals. Busy lifestyles, lack of knowledge and poor diets are often to blame.
Adequate amounts of different types of nutrients are important for every living organism. Nutrients from different foods give our systems the essential materials required for strong and healthy bodies.
There are many types of nutrients and each of them has a specific purpose. Learning about key nutrients that your body needs – and why – is the first step toward improving your overall health and possibly preventing disease.
Here are the top 10 essential nutrients for your body.
1. Vitamin A
This essential vitamin plays an important role in general growth and development, including proper vision, healthy teeth, glowing skin, strong bones and more.
Vitamin A also protects the body from different types of infections and promotes the health and growth of cells and tissues in the body. Vitamin A comes in two forms – retinoids and carotenoids.
Some foods rich in vitamin A are carrots, sweet potatoes, cantaloupe, pumpkin, spinach, eggs, watermelon, kale, papaya, peaches, apricots, tomatoes, dried beans, lentils, red peppers, guava, broccoli, liver, milk and fortified cereals.
2. Vitamin C
This water-soluble vitamin is an antioxidant that helps protect cells from free-radical damage, lowers the risk of different types of cancer, regenerates your vitamin E supply, and improves iron absorption. It also keeps the gums healthy, aids in healing wounds, boosts the immune system, and keeps infections at bay.
Your body can’t store vitamin C or make it, so you need to consume some every day. Some foods rich in vitamin C are red peppers, kiwi, oranges, strawberries, cantaloupe, broccoli, guava, grapefruit, Brussels sprouts, parsley, lemon juice, papaya, cauliflower, kale and mustard greens.
3. Vitamin E
Vitamin E is the collective name of eight fat-soluble compounds with distinctive antioxidant activities. This particular vitamin protects the skin from harmful ultraviolet light, prevents cell damage from free radicals, improves communication between cells, and protects against prostate cancer and Alzheimer’s disease.
Some foods rich in vitamin E are spinach, chard, turnip greens, mustard greens, cayenne pepper, almonds, sunflower seeds, wheat germ, asparagus, bell peppers, whole grain cereals and safflower oil.
4. Dietary Fiber
The American Dietetic Association defines fiber as complex carbohydrates that the body can’t digest or absorb. Instead, it passes relatively intact through your stomach, small intestine, and colon and out of your body.
A high-fiber diet normalizes bowel movements, helps maintain bowel health, lowers cholesterol levels, helps control blood sugar levels, and aids in achieving healthy weight. It also lowers the risk of developing chronic conditions, including heart disease, cancer, and type 2 diabetes.
Some foods with high fiber content are whole grain crackers, quinoa, millet, barley, cracked wheat, wild rice, black beans, chickpeas, turnip greens, oats, flaxseed, mustard greens, collard greens, navy beans, eggplant, raspberries, and cinnamon.
5. Folic Acid (Vitamin B9)
Folic acid, also known as folate, is a form of the water-soluble vitamin B9. Folic acid supports red blood cell production to prevent anemia, prevents homocysteine buildup in your blood, and helps the nerves function properly. It also prevents osteoporosis-related bone fractures and dementias, including Alzheimer’s disease.
The body cannot store folic acid, so it is highly essential to consume it every day to maintain an adequate amount in your system.
Some good food sources of folic acid are romaine lettuce, spinach, asparagus, turnip greens, mustard greens, parsley, collard greens, broccoli, cauliflower, beets, lentils, asparagus, cabbage, egg yolks and lettuce.
Iron helps make red blood cells, which carry oxygen around the body. It is also necessary to support proper metabolism for muscles and other active organs. A lack of iron in the body can lead to iron-deficiency anemia that can result in fatigue, weakness, and irritability.
Some iron-rich foods are oysters, red meats, chicken liver, soybeans, fortified cereal, pumpkin seeds, beans, lentils, spinach, nuts, dried apricots, brown rice, watercress, kale, Swiss chard, thyme, asparagus, cumin, turmeric, tofu, blackstrap molasses, collard greens, leeks, oregano, black pepper, basil and turnips.
Also increasing the amount of vitamin C in your diet will help your body absorb iron more effectively.
