1. They are high in vitamin B6. Vitamin B6 helps reduce the chemical homocysteine in our bodies. Homocysteine has been linked with degenerative diseases, including the prevention of heart attacks.
2. They are a good source of vitamin C. While most people know that vitamin C is important to help ward off cold and flu viruses, few people are aware that this crucial vitamin plays an important role in bone and tooth formation, digestion, and blood cell formation. It helps accelerate wound healing, produces collagen which helps maintain skin’s youthful elasticity, and is essential to helping us cope with stress. It even appears to help protect our body against toxins that may be linked to cancer.
3. They contain Vitamin D which is critical for immune system and overall health at this time of year. Both a vitamin and a hormone, vitamin D is primarily made in our bodies as a result of getting adequate sunlight. You may have heard about seasonal affective disorder (or SAD, as it is also called), which is linked to inadequate sunlight and therefore a vitamin D deficiency. Vitamin Dplays an important role in our energy levels, moods, and helps to build healthy bones, heart, nerves, skin, and teeth, and it supports the thyroid gland.
4. Sweet potatoes contain iron. Most people are aware that we need the mineral iron to have adequate energy, but iron plays other important roles in our body, including red and white blood cell production, resistance to stress, proper immune functioning, and the metabolizing of protein, among other things.
5. Sweet potatoes are a good source of magnesium, which is the relaxation and anti-stress mineral. Magnesium is necessary for healthy artery, blood, bone, heart, muscle, and nerve function, yet experts estimate that approximately 80 percent of the population in North America may be deficient in this important mineral.
Superior fiber content
Sweet potatoes contain almost twice as much fiber as other types of potatoes. Contributing close to 7 grams of fiber per serving, they make an excellent starchy addition to any meal. The high fiber content gives them a “slow burning” quality. This basically means their caloric energy is used more slowly and efficiently than a low-fiber carbohydrate.
They contain a large amount of vitamin B6. This vitamin is crucial in breaking down a substance called homocysteine, which contributes to hardening of the arteries and blood vessels. Vitamin B6 helps keep the walls of these important blood passageways flexible and healthy which allows blood to flow freely.
In addition, sweet potatoes contain high amounts of potassium. Potassium plays an important role in lowering blood pressure by ridding the body of excess sodium and regulating fluid balance. It is also an important electrolyte that helps regulate the natural rhythm of the heart, and maintains normal function of the brain and central nervous system.
7. Rich in beta-carotene
Beta-carotene or vitamin A is an important antioxidant. One medium sweet potato provides your body with the complete recommended daily allowance of vitamin A and then some. Vitamin A is useful in the prevention of several different types of cancer as it is one of the most potent antioxidants out there.
Beta-carotene also helps to internally protect your skin from sun damage by both deflecting and repairing cell damage caused by excessive UV exposure. It also is an excellent nutrient for eye health and has been linked to prevention of vision loss and macular degeneration.
8. A great source of manganese
Manganese is a little-discussed trace mineral that has some great health benefits. It is a pivotal component in the metabolism of carbohydrates which helps support healthy blood sugar levels. This can help stabilize the appetite for hours as opposed to the temporary satisfaction that comes with most other carbohydrates.
It also is a cofactor in enzymes that play an important role in the generation of energy as well as the efficient utilization of antioxidants. It is used for the treatment of anemia and is useful as a treatment for several premenstrual symptoms in women as well.
9. Rich in vitamins C and E
As if being one of the top vegetable sources of beta-carotene weren’t enough, sweet potatoes are also rich in vitamins C and E. These are potent antioxidant vitamins that play an important role in disease prevention and longevity.
Both vitamins also play a huge role in the health and beauty of your skin and hair, making them popular supplements. The combination of beta-carotene, vitamin E and vitamin C in one food makes the sweet potato one heck of a “beauty food”. These nutrients all contribute to a healthy, glowing complexion and vibrant hair.
