In a recent study published in the American Journal of Clinical Nutrition, Dr. K Srinath Reddy, a distinguished professor at the Public Health Foundation of India (PHFI), sheds light on the benefits of plant proteins for women’s health as they age. The findings suggest that incorporating lentils, beans, nuts, and seeds into the diet may contribute to better physical function and mental well-being in middle-aged and older women.
Understanding Healthy Ageing
Healthy ageing is more than just the absence of chronic diseases; it encompasses good mental health and preserved cognitive and physical function. The study aimed to explore the role of protein intake, particularly from plant sources, in promoting healthy ageing among women.
Insights from the Study
The study revealed a significant association between protein intake and healthy ageing. For every three percent increase in daily calories from protein, the likelihood of healthy ageing in women increased by 38 percent. Interestingly, plant proteins showed the highest odds ratio for promoting healthy ageing compared to animal proteins.
Why Plant Proteins Work for Women
Researchers attribute the beneficial effects of plant proteins to their rich content of dietary fibers, micronutrients, and polyphenols. These components found in plant-based foods contribute to overall health and may play a protective role against chronic diseases. Additionally, phytoestrogens present in plant foods mimic estrogen, which could be particularly beneficial for women experiencing hormonal changes in middle age.

Balanced Diet Approach
Dr. Reddy emphasizes the importance of a balanced diet that includes both plant and animal proteins. While animal proteins offer a better protein composition, plant proteins come with additional protective nutrients and high fiber content. A combination of rice and lentils, for example, provides a complete amino acid profile, supporting overall health and well-being.
Significance of Protein Intake
Higher protein intake has been linked to reduced muscle loss, improved bone density, and enhanced physical performance in older adults. Plant proteins, in particular, show promise in mitigating the risk of chronic diseases, making them an essential component of a healthy ageing diet.
Trustworthiness of the Study
The study, conducted on nearly 50,000 participants from the Nurses’ Health Studies, offers valuable insights into healthy ageing among women. While the findings are compelling, it’s essential to note that the study primarily focused on White females, limiting its generalizability to other populations. Nonetheless, it serves as a significant step towards understanding the role of nutrition in promoting healthy ageing in women.
In conclusion, embracing plant proteins as part of a balanced diet can be a key strategy for women to age gracefully while maintaining optimal physical and mental well-being.
