Is there an Alzheimer's sugar connection?
There’s growing evidence that high sugar intake—especially refined sugar and chronically elevated blood glucose—may contribute to Alzheimer’s risk, though the relationship is complex rather than direct. 🍬 What researchers have found Insulin resistance in the brain: Alzheimer’s is sometimes called “type 3 diabetes” because insulin signaling in the brain can become impaired. When neurons can’t use glucose efficiently, they begin to degenerate. Chronic inflammation: Diets high in added sugars promote systemic inflammation, which can damage blood vessels and brain tissue over time. Oxidative stress: Excess sugar accelerates formation of advanced glycation end products (AGEs) —molecules that stiffen tissues and interfere with normal protein function, including in the brain. Vascular damage: High blood sugar harms small blood vessels, reducing oxygen and nutrient delivery to the brain, which can worsen cognitive decline. 🍓 What seems protective Diets rich in whole fruits, vegeta...
