Plant active ingredients protect against Alzheimer's
Ingredients from fruits and vegetables have a positive effect on our health. This realisation is not new. A recent study found that phytosterols also help prevent Alzheimer's.
High cholesterol has long been suspected of increasing the risk of developing Alzheimer's. Cholesterol promotes the formation of so-called senile plaques. These plaques consist of proteins, especially the beta-amyloid proteins, and are deposited on the nerve cells in the brain. They are considered one of the main triggers of Alzheimer's.
Scientists at Saarland University have now shown that a certain sterol, stigmasterol, inhibits the formation of proteins that play an important role in the development of the disease. Vegetable sterols are found in different compositions, for example in nuts, seeds and vegetable oils. They are the equivalent of animal cholesterol and can therefore have their metabolic effects in the same places as cholesterol. (pm)
