A study featured in the Harvard Health Letter (June 2022) highlights the potential cognitive benefits of adequate dietary protein.
Over two decades, researchers examined the dietary patterns and health outcomes of more than 77,000 adults. They discovered that higher protein consumption, as opposed to carbohydrates, correlated with a reduced likelihood of cognitive decline in later years.
Notably, replacing 5% of caloric intake from carbohydrates with animal protein was linked to an 11% decrease in dementia risk, while the same caloric substitution with plant protein corresponded to a 26% reduction.
Among plant-based proteins, beans and legumes, especially peas and lima beans, showed the most significant protective effects; an additional three weekly servings were associated with a 28% lower risk of cognitive decline.
It’s important to note that this observational study doesn’t establish a direct cause-and-effect relationship between protein intake and brain health. Nevertheless, proteins are vital for muscle and organ function, tissue and cell repair, and the production of essential brain chemicals.
Incorporating protein-rich foods, particularly plant-based options like beans, lentils, nuts, and seeds, into your meals may support overall health–including your cognition.
