Alzheimer's disease and diet

1-minute read

To help prevent Alzheimer’s disease, a low-fat and high-fibre diet is recommended. This includes plenty of fresh fruit and vegetables (5 portions a day) and wholegrains.

Limit the amount of salt that you eat to no more than six grams a day. Too much salt may increase your blood pressure, which puts you at risk of vascular dementia, which is where dementia is caused by poor blood supply to the brain. One teaspoonful of salt is about 6 grams.

Avoid eating foods that are high in saturated fat because this may increase your cholesterol level, which also puts you at risk of vascular dementia. You may also wish to choose to eat low fat or fat-free dairy products (milk, yoghurt and cheese).

Eating some foods that are high in unsaturated fat may actually decrease your cholesterol level.

Foods high in unsaturated fat include:

  • oily fish
  • avocados
  • nuts and seeds
  • sunflower, canola and olive oils.
