Can a high-fat diet accelerate ageing-related memory loss? Study sheds light
Advertisement
A recent study published in the journal Neurobiology of Aging determined whether a high-fat diet contributes to memory decline in older people compared to aging alone.
Increased consumption of highly processed foods, which are rich in calories but poor in nutrients, has contributed to rising rates of obesity and related diseases like high blood pressure and type 2 diabetes mellitus. These conditions are risk factors for cardiovascular disease (CVD) and cancer.
Obesity is also linked to cognitive dysfunction, including anxiety, depression, memory decline, and impaired learning. Neuroinflammation, a consequence of obesity, further exacerbates cognitive impairment and neurodegeneration.
High-fat diets can induce inflammatory neuronal damage within a week of exposure, leading to dysregulated feeding and weight gain. Additionally, these diets can trigger hippocampal inflammation, resulting in memory deficits.
