‘Healthier Aging’ For Women Who Eat More Plant Protein, Study Finds

A new study suggests that women who consume higher amounts of plant-based protein may experience healthier aging. Researchers tracked nearly 50,000 women over a 32-year period to evaluate their levels of "healthy aging," defined as being free from major chronic diseases, having good mental health, and no impairments in cognitive or physical function. Those who consumed larger quantities of plant-based protein in midlife were found to have higher odds of healthy aging, including a reduced risk of heart disease, cancer, diabetes, and cognitive decline.

The study, published in The American Journal of Clinical Nutrition and led by Andres Ardisson Korat, adds to the existing body of research linking plant-based foods to better health outcomes as people age. Plant-based proteins were associated with a 46 percent higher likelihood of healthy aging compared to animal proteins, with plant-based diets contributing to lower LDL cholesterol, blood pressure, and insulin sensitivity. The research highlights the potential benefits of adopting a plant-based diet for promoting a healthier, disease-free lifestyle as individuals grow older.
