An increase of this nutrient will help immensely.
A recent study suggests that maintaining a diet rich in protein, particularly plant-based protein, may contribute to healthier aging in women. The analysis, which drew on data from over 48,000 women, revealed that a 3% increase in the consumption of plant protein was linked to a 38% higher likelihood of maintaining good health as women age. This translates to experiencing fewer or no chronic diseases, enjoying better physical mobility, and encountering minimal cognitive decline.
Andres Ardisson Korat, the lead author and a scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, highlighted the positive association of plant protein with good mental health and a lack of impairments in memory. Compared to other nutrients, plant protein is associated with a reduced risk of cardiovascular disease and other chronic conditions. Moreover, it plays a role in promoting good physical function by enhancing muscle synthesis.
Plant protein also stands out for being sourced from foods with high-quality carbohydrates, containing more fiber, vitamins, minerals, and antioxidants. The study delved into data from the Nurses’ Health Study, spanning over four decades and tracking participants’ food consumption frequency. To be classified as healthy between the ages of 70 to 93, women had to be free from major chronic health conditions associated with aging, such as cancer, Type 2 diabetes, cardiovascular diseases, and more.
The study findings indicated that women who consumed more plant proteins were 46% more likely to remain healthy into their later years. Conversely, those who consumed more animal proteins showed a 6% lower likelihood of maintaining health as they aged. However, it’s essential to note that the study predominantly involved white women, and the applicability of the findings to other groups remains uncertain.
While the study underscores the potential benefits of plant proteins for healthy aging, it does not definitively establish a causal relationship. The results align with previous research suggesting that individuals, particularly vegetarians, who incorporate plant proteins into their diets tend to have lower cholesterol levels, better calorie-burning abilities, and reduced risks of inflammation and dementia.
Despite the limitations of nutrition studies relying on questionnaires, the extensive follow-up in this research instills confidence in the observed associations. Experts emphasize the positive perspective of focusing on prolonged health rather than merely preventing disease or death. Cardiologists recommend adopting a plant-based diet, supported by evidence showing benefits in reducing heart attack and cancer risks. However, acknowledging potential confounding factors, such as overall diet quality and lifestyle, is crucial when interpreting the study’s results.
