Research suggests incorporating more whole grains, like popcorn, into your diet could reduce the risk of cognitive decline. A study published in Neurology found that people who ate more whole grains were cognitively younger than those who ate less. Dr. Xiaoran Liu stated that increasing whole grain consumption by a couple of servings a day could potentially lower the risk of dementia.
The study defined whole grains as bread, cereals, quinoa, and popcorn, with one serving being one ounce of food. Researchers observed 3,326 people, around 75 years old, who completed a diet survey and underwent cognitive tests every three years. Participants who ate three servings of whole grains per day experienced slower cognitive decline than those who ate less.
Black participants were more likely to consume more than one daily serving, with significant health benefits linked to whole grains. Nutrient-dense foods like oats, brown rice, and popcorn have shown to lower cholesterol, insulin levels, and blood pressure. Additionally, whole grains are rich in vitamin B and E, fiber, and antioxidants, benefiting heart and brain health.
The study found that Black participants consuming more than three daily servings of whole grains experienced slower cognitive decline. Although additional studies are needed, this research supported by the Alzheimer’s Association and the National Institutes of Health could lead to tailored diet recommendations.
