In a study, scientists found that decreasing folate intake can support healthier metabolisms in aging animal models, challenging the conventional belief that high folate consumption universally benefits health. Folate, a B vitamin essential for cell growth and development, is widely recognized for its role in preventing birth defects. It's found naturally in foods like leafy greens, and it is typically added to refined grains. By limiting folate in animal models, the researchers saw a decrease in processes related to growth and building new cells, but enhanced metabolic flexibility, which Polymenis said could lead to healthier aging. "Optimal folate intake may...
