The Fish’s Rival? Yam Stands Out As A Superfood For The Brain And Memory

Rich in fiber, vitamins, and a compound that stimulates neuronal growth, yam is earning a place as a powerful ally for cognitive, digestive, and hormonal health in everyday life.

Discover the superpowers of yam, the carbohydrate that’s good for both body and mind.

When looking for foods that nourish the body and strengthen the mind, many people think of fish rich in omega-3. However, a classic ingredient in Brazilian cuisine is gaining attention for its surprising brain health benefits: yam.

With its tough skin and white flesh, this popular tuber is rich in fiber and vitamins, and studies have shown it to be a natural booster for memory, learning, and neuronal growth.

Native to tropical regions such as West Africa and South America, yam is a complex carbohydrate with a low glycemic index, meaning longer-lasting energy and fewer blood sugar spikes.

Much More Than Calories

More than just a source of energy, yam provides a powerful combination of nutrients that support bone, cardiovascular, and even hormonal health, making it a functional food.

Versatile in the kitchen, it can be eaten boiled, roasted, or in soups. Including this tuber in your daily diet is a practical and tasty way to care for your health from the inside out, with positive effects on quality of life and cognitive performance.

According to the U.S. National Library of Medicine, a single serving of yam provides about 20% of the daily requirement for essential micronutrients—a significant figure for those seeking balanced nutrition.

Diosgenin: The Secret Behind Yam’s Power

Among yam’s most remarkable compounds is diosgenin, a phytoesteroid with a structure similar to hormones such as estradiol and progesterone. This substance is used as a base for the production of synthetic steroid hormones.

Studies show that diosgenin can help alleviate symptoms of menopause and premenstrual syndrome, as well as offer potential benefits in combating diseases such as cancer and atherosclerosis.

In the brain, diosgenin stands out for its ability to stimulate neuronal growth and strengthen memory. It can also improve learning capacity, making yam a true natural tonic for the mind.

Digestive Health and Long-Lasting Energy

Beyond its effects on the brain, yam is excellent for the gut. Its high fiber content helps regulate intestinal transit and promotes overall digestive health.

This fiber also promotes satiety, which can help those seeking healthy weight loss. Thanks to its slow-release energy, this tuber is ideal for those who need sustained energy, such as athletes or people with long workdays.

Plenty of Vitamins and Minerals

Yam’s nutritional value doesn’t end there. It’s rich in vitamins C, A, and several B-complex vitamins, and provides essential minerals like potassium, calcium, iron, manganese, phosphorus, and copper.

With so many benefits, yams are solidifying their place as an affordable, versatile, and highly nutritious superfood—a true rival to fish when it comes to brain health.
