Before you pile on tomatoes, potatoes and cucumber, be careful. According to a study, they contain a protein that might lead to Alzheimer’s disease.

Dr Steven Gundry, a heart surgeon and cardiologist specialist from California said that he found a link between memory loss and lectins, found in cucumbers, tomatoes, whole grains, soy, grains, peppers, sprouted grains and some dairy products.

Gundry stated that such food could even lead eaters to develop dementia.

According to researchers, lectins are harmful to the gut and could cause a host of issues – and possibly memory loss.
