Advocates of healthy eating and nutritionists have another reason to say no to junk food: Dementia.
A recent study claims that junk food could be bad for your memory, and may lead to dementia, and trigger Alzheimer's. Junk food is already linked with obesity and diabetes, especially in the U.S.
Too much junk food leads to an increase in the secretion of insulin, a hormone. A decrease in the ability of cells to respond to high levels of insulin is likely to affect the brain, leading to dementia.
