Dietary studies link MIND diet to lower dementia risk and ketogenic diet to improved metabolic health

Recent nutritional studies have highlighted the impact of specific dietary patterns on cognitive health and metabolic functions. A large-scale American study involving approximately 93,000 participants found that following the MIND diet—a hybrid of the Mediterranean and DASH diets—can significantly reduce the risk of dementia. Long-term adherence for at least 10 years was associated with a 25% reduction in dementia risk. The diet emphasizes plant-based foods, including leafy greens, berries, whole grains, legumes, nuts, and olive oil, while limiting red meat, sweets, and processed foods.

In a separate study published in the journal Cell Metabolism, researchers compared the ketogenic, Mediterranean, and high-carbohydrate plant-based diets in individuals with obesity, prediabetes, and fatty liver disease. While all three diets resulted in roughly a 10% weight loss, the ketogenic diet was notably more effective at improving liver health. Participants on the ketogenic diet saw a 67% reduction in liver fat and a 20% decrease in 24-hour blood glucose levels. Additionally, 50% of participants on the ketogenic diet successfully normalized their blood sugar levels, compared to 29% for the Mediterranean diet and 7% for the plant-based diet.
