Have you ever wondered what makes yams different from sweet potatoes? Yams are a type of tuber that come from Asia, Africa, and the Caribbean. They are often mixed up with sweet potatoes. But, they have their own unique taste, texture, and nutrients.
Yams look like they have bark on the outside and can be white, yellow, purple, or pink inside. They are starchier and less sweet than sweet potatoes. This makes them special in the kitchen.
Yams are great for Thanksgiving side dishes and many other recipes around the world. They add nutrition and flavor to your meals.
The Nutritional Powerhouse
Packed with Vitamins, Minerals, and Fiber
Yams are a nutrient-dense root vegetable. They have a lot of vitamins, minerals, and fiber. One cup (136 grams) of baked yams has 158 calories, 37 grams of carbs, 2 grams of protein, and 5 grams of fiber.
These tubers are great for vitamin C, giving you 18% of the Daily Value (DV). They also have vitamin B5, manganese, magnesium, potassium, thiamine, copper, and folate. Each one is important for your health.
Yams are full of fiber, which is good for your digestive health, blood sugar, and overall health. They have a lot of potassium and manganese. These nutrients help with bone health, growth, metabolism, and heart function.
Yams are full of nutrient-dense stuff like macronutrients, vitamins, minerals, and fiber. They give your body lots of important micronutrients. This helps with your health and well-being.
Brain Boosters
Yams have a special compound called diosgenin. This helps grow neurons and boost brain function. In a 12-week study, those who took yam extract did better on a brain test than the control group.
Diosgenin also helps improve memory and learning abilities in mice. This means yams could be good for cognitive health. But, we need more studies to know how yams affect the brain.
There were 28 healthy people in the study, aged 20 to 81. Those who took the yam extract for 12 weeks did better on a test of brain function. They also got better at semantic fluency, one part of a bigger test.
No one reported any bad effects in the study. The yam extract had 5.6% diosgenin and 672 mg of olive oil. Researchers used tests like the RBANS and MMSE-J to check brain function. They also looked at how smart the people were before the study.
These results show that yams, with their compounds like diosgenin, might help with brain health and cognitive function. But, we need more research to understand how yams work on the brain over time.
| Study Details | Findings |
|---|---|
| 12-week yam extract intervention | Significant increase in total RBANS score |
| 28 healthy volunteers (age: 20-81 years) | Significant improvement in semantic fluency |
| 5.6% diosgenin content in yam extract | No adverse effects reported |
| 672 mg olive oil in yam extract capsules | Potential benefits for brain health and cognitive function |
Yams
Yams are a versatile root vegetable with over 600 types. They are a key source of carbs and nutrients in Africa, Asia, and the Caribbean. The main types include Dioscorea alata (water yam), Dioscorea rotundata (white yam), and Dioscorea cayenensis (yellow yam).
Dioscorea species differ in size, shape, and color. They taste mildly sweet and are nutritious. Yams can be as long as an adult arm. They often have white flesh, but some have red, yellow, and purple colors.
