Preventing memory loss as we age may be as simple as eating peanut butter and red grapes for lunch, or drinking a glass of red wine with dinner. Resveratrol – an antioxidant compound in red grapes and peanuts – has already been shown to improve heart health… And new research in Scientific Reports shows it improves spatial learning and memory, too. In fact, resveratrol may even be able to boost the brainpower of people with severe neuro-degenerative conditions, like Alzheimer’s disease. So, have a peanut butter sandwich at lunch – and red grapes as a snack.
