Scientists at the University of Helsinki have uncovered an unexpected link between the body’s resistance to the flu virus and a diet low in carbohydrates and high in fat. The findings were published in the Scandinavian Journal of Public Health (SJPH).
The ketogenic diet, which prioritizes a high intake of fats, has been used for over a century to manage severe neurological conditions. The macronutrient ratio in this diet is typically 20–25% protein, 70% fat, and 5–10% carbohydrates. It emphasizes the consumption of gluten-free and starch-free carbohydrates.
A recent study, led by nutritionist Astrid Heismans and her team of scientists, has uncovered a new mechanism that could profoundly influence preventive medicine. The research revealed that during the ketogenic diet, gamma-delta T-lymphocytes—cells essential for antiviral immunity—are activated in the body.
However, the research findings have sparked debate among experts. Some scientists argue that additional clinical studies are needed to confirm the safety of long-term adherence to the ketogenic diet. Researchers at the University of Helsinki plan to conduct these studies to identify the diet’s optimal duration and composition.
