If you are wondering what the hype is all about yams, then you have come to the right place. This tasty and nutritious root vegetable has been gaining popularity in recent years, and it’s no wonder why. Not only does it taste great, but yams are also packed with nutrients that are essential for your health. But before we dive into the health benefits, let’s first clarify what yams really are and what makes them different from sweet potatoes.
Yams are tuber vegetables that are native to Africa and Asia. They are a part of the Dioscoreaceae family and have been a staple food in many cultures for centuries. Yams are cylindrical in shape and have a rough, scaly exterior. The flesh is usually white or yellow and has a starchy texture. On the other hand, sweet potatoes are a part of the Convolvulaceae family and are native to the Americas. They have a more elongated shape and have smooth, thin skin. The flesh of sweet potatoes can vary from white to orange and has a sweet taste.
The Nutritional Profile of Yams
Yams are low in fat and high in carbs, making them an excellent source of energy. They are also high in fiber, which helps regulate digestion and keeps you feeling full for longer. Yams are also packed with various vitamins and minerals, including:
- Vitamin C: Yams contain a high amount of vitamin C, which promotes healthy immune function and helps your body absorb iron from plant-based sources.
- Potassium: Yams are an excellent source of potassium, which helps regulate blood pressure and maintain proper heart function.
- Vitamin B6: Yams are rich in vitamin B6, which is essential for brain function and helps your body produce serotonin, a neurotransmitter that regulates mood.

Health Benefits of Yams
1. May Improve Digestive Health
Yams are rich in fiber, which is essential for maintaining healthy digestion. Fiber helps regulate the movement of food through your intestines and promotes the growth of beneficial gut bacteria. This can help prevent constipation, reduce inflammation in the gut, and lower the risk of colon cancer.
2. May Reduce Inflammation
Inflammation is a natural response that your body has to protect itself against infection or injury. However, chronic inflammation can contribute to various health problems, including heart disease, cancer, and diabetes. Yams contain various anti-inflammatory compounds, including anthocyanins and diosgenin, which can help reduce inflammation and lower the risk of chronic diseases.
3. May Lower Blood Sugar Levels
Yams have a low glycemic index, which means that they cause a slower and more steady increase in blood sugar levels compared to high-glycemic foods. This makes yams a great option for people with diabetes or those looking to control their blood sugar levels.
4. May Boost Brain Function
Yams are rich in vitamin B6, which is essential for brain function. Vitamin B6 helps your body produce neurotransmitters that regulate mood, as well as the hormones melatonin and serotonin, which play a role in sleep and mood regulation. Some studies have also shown that yams can improve cognitive function and reduce the risk of Alzheimer’s disease.
5. May Enhance Immune Function
Yams are high in vitamin C, which is a potent antioxidant that helps protect your cells from damage caused by harmful molecules called free radicals. Vitamin C also plays a role in immune function by promoting the production of white blood cells that fight off infections.
Cooking with Yams
Yams can be used in a variety of different recipes, from savory stews to sweet desserts. They can be baked, boiled, fried, or mashed, and can be seasoned with a variety of flavors, such as cinnamon, nutmeg, or garlic. Yams are also a great addition to salads, soups, and curries. Here are some tips to help you cook with yams:
- Choose yams that are firm and free from soft spots or blemishes.
- Peel yams before cooking to remove the rough exterior.
- Cut yams into smaller pieces before boiling to reduce cooking time.
