A low-carbohydrate, high-protein diet has been shown to slow the growth of tumors and reduce the risk of cancer in mice. The study found that restricting carbohydrate intake can limit blood glucose and insulin, promoting tumor growth. A low-carb diet also boosted the immune system's ability to kill cancer cells and prevented obesity.
A study found that a low-saturated fat and low-glycemic index diet decreased certain biomarkers of Alzheimer's disease in healthy adults, while also improving memory performance. However, the diet had the opposite effect on individuals with mild cognitive impairment, potentially due to its short duration.
A new animal study finds that a high-fat diet can cause inflammation and injury to brain cells in the hypothalamus, leading to weight gain. The research suggests that this neuronal injury may be permanent, contributing to the difficulty of achieving sustained weight loss in obese individuals.
