Here are the 7 health benefits of yam.
1. Yams are perfect for helping decrease blood pressure
Yams have one of the highest amounts of potassium per cup among staple foods. Per cup, yams contain 1,224 milligrams or 35 percent of the daily recommendation for potassium. Also, yams contain very little sodium with only 13.5 milligrams per cup. This combination with folate also contributes to the reduction of hypertension and relaxes blood vessels, while maintaining proper blood flow.
2. Yams may improve brain cognition
Several components of yams, such as potassium, folate, and various antioxidants are known to provide neurological benefits. Folate has been known to reduce the occurrence of Alzheimer’s disease and cognitive decline. Potassium has been linked to increased blood flow to the brain and heightens cognition, concentration, and neural activity.
3. Yams can help improve heart health
Yams are rich in vitamin B6, potassium, and dietary fiber. One study suggested that individuals who consumed 4,069 mg of potassium per day had a 49 percent lower risk of death from ischemic heart disease compared with those who consumed less than 1,000 mg per day.
4. Yams are a wonderful source of manganese
Manganese is essential for many enzymes that control blood sugar, energy metabolism, and thyroid function. One cup of yams possesses 30 percent of the recommended value of manganese. Deficiencies in manganese could be associated with impaired fertility, growth retardation, congenital disabilities, and general weakness.
5. Yams can help individuals fight infections
Yams contain 43 percent of the vitamin C daily requirements per cup. Vitamin C is a powerful natural water-soluble antioxidant that helps the body develop resistance against infectious agents and eliminates cancer-causing free radicals in the body.
6. Yams are great for keeping the hair and skin vibrant and strong
Adequate vitamin C intake does not only improve the immune system but can also create and maintain collagen, an essential protein found in hair and skin.
7. Yams help aid the digestive system
Yams are a great source of fiber. A one-cup serving of yams contains 6 grams of dietary fiber. The daily recommended dietary fiber intake for men and women are 38 grams and 25 grams, respectively. Fiber aids can help prevent constipation, making your bowel movement easier to manage.
