According to a study done two years or so ago at Johns Hopkins University, protecting your hearing may help protect you from Alzheimer's disease. The study found that when the brain has to work really hard to decipher what is being said, its ability to form and keep memories can decline. Here is a tip from an Australian study that might help. The Australian study found that eating 2 cups of sweet potatoes and 4-ounces of almonds weekly could cut ones risk of hearing problems by as much as half. The reason? These are superfoods that are packed with the nutrients that keep even the tiniest blood vessels healthy and plaque free. This keeps the ears from being starved of oxygen according to the Australian authors of the study.
