Today on Healthy Talk, you wanted to know:What's the difference between a legume and a nut?A legume is a dried fruit inside of a pod (or what's called a shed). It's called a legume because you're able to peel the shed off, instead of a nut where you crack its shell.My wife and daughter were arguing about which nuts were the healthiest. They have no idea what they're talking about. Can you help them?All nuts are all similar in calories per ounce. There are some lower-calorie nuts, like almonds, cashews, and pistachios. The highest calorie nuts are pecans and macadamias.However, it's really hard to rank which are "unhealthy," since they all contribute to your health differently. For example, the best nut for your brain is the peanut. Walnuts are great for your heart. Almonds are high in fiber, low in calories, and contain tons of vitamins and calcium.My wife says there's no nutritional value to peanuts (which I love). She wants me to eat walnuts or almonds (which I hate). Do I really need to switch?Like Dr. Mike was stating earlier, peanuts have a lot of good antioxidants, folic acid, healthy fats, vitamin E and are great for your brain.You don't necessarily need to stop eating peanuts, but you might want to try other nuts like walnuts since they aid in heart hearth.If you have a health question or concern, Dr. Mike encourages you to write him at askdrmikesmith@radiomd.com or call in, toll-free, to the LIVE radio show (1.844.305.7800) so he can provide you with support and helpful advice.
