Age changes not only our appearance and energy levels but also how our bodies respond to food. Recent scientific studies show that the same diet can have different effects on men and women, especially in later life.
It turns out that gender plays an important role in maintaining metabolic health, and what is beneficial for men does not necessarily produce the same results for women.
What Happens to Metabolism as We Age
As we grow older, metabolism naturally slows down. Blood sugar regulation becomes more difficult, and the risk of insulin resistance and type 2 diabetes increases. This process is also influenced by a phenomenon known as inflammaging—chronic, age-related inflammation that significantly affects metabolic health.
However, these changes do not occur in the same way for everyone.
What the New Study Revealed
A study published in the scientific journal Nutrients analyzed data from 96 healthy older adults with an average age of 69. Participants:
kept detailed food diaries
underwent glucose tolerance tests
had their body composition measured
had their physical activity levels assessed
The data were analyzed using statistical models adjusted for body mass index (BMI) and physical activity.
Men and Women: Different Dietary Responses
The study identified notable gender-specific differences.
In Men
Better insulin sensitivity was observed when diets were higher in:
plant-based proteins
whole grains
inositol
vitamin E
In contrast, higher consumption of trans fats and refined grains was associated with poorer metabolic indicators.
In Women
Moderate wine consumption and xylitol (a sugar substitute) initially appeared to be linked to improved insulin sensitivity.
However, after additional statistical adjustments, this association was no longer considered significant.
An interesting finding is that before menopause, women’s livers process lipids more efficiently than those of men of the same age, though these differences in older age are still not fully understood.
What Scientists Say
Researchers emphasize that these findings are preliminary and may not apply to people of different ethnic backgrounds or with varying health conditions. Nevertheless, the results strongly suggest that a “one-size-fits-all” dietary approach does not work in older age.
Further research is needed to determine which dietary strategies are most effective for specific genders and age groups.
