What's the topic for this week this week? We are talking about bananas bananas. Yeah, you know, we always have that old adage of an apple a day keeps the doctor away, but we can actually add a banana into that too and banana a day may keep the heart disease away. Oh heart disease. Okay. Well, I'm listening bananas have a lot of cardiovascular health benefits because of the nutrients that are in them and here again kind of like wage. Talked about on a previous podcast of potatoes being banished right as a a food that is too high in whatever bananas have often been relegated to that category as well because they're always considered to be thinking that they're high in sugar and that sugar content is, you know too much for our you know, our blood sugar levels that but actually a bananas are actually in the office low glycemic category. Hm all different stages of ripeness. So for example, a under ripe banana, which we would basically call like a green banana. It's glycemic index level is a 30 which is really low to be low glycemic. You need to be between 1 and 55. So 30 is considered a very low glycemic if you have a slightly under ripe banana, that's yellow with a little bit of green. The GI is 42. Okay, and then in a ripe banana cake Can all yellow his fifty-one so you're kind of getting close to the 55, but it's still in the low range and then an overripe yellow flecked with brown has a GI of Forty-Eight. So all varieties of banana and no matter what type stage they're all low low glycemic. Hm. So I think that that's a you know, it's a myth that's been perpetuated and of course, you know, we have different sized bananas that you can buy. There's like really big ones during those small ones. So I always try to go with the medium sized banana cuz that's what these GI numbers are from. Well I can see why the internet just kind of grabs onto that. It's got a lot of sugar boy if we only didn't have bananas we would be better people. I don't know what the deal is but they really don't like bananas the internet. Yeah, and you know, we see that in low carb diets and those types of things that bananas are off the list but so here's a nutrient quality of bananas. They're high in vitamin K. 6 about 25% of our daily value comes from a banana and they also have vitamin C fiber 11% of our daily need for fiber is from a banana. And of course, they're very rich in potassium. Oh, that's that a medium sized banana has about four hundred milligrams of potassium. So I'm not good for our emotional health isn't that potassium is good for a number of things but really good for the cardiovascular system potassium is also an electrolyte so long we need it to have fluid balance within our body kind of has an electrolyte is something that has like a little electrical charge within the body. So it it actually takes care of our own nervous system all of the nerve impulses that we have. So potassium's important for that. But in terms of cardiovascular health are actually three different ways that bananas help. So the first one off It has to do with the potassium content because potassium is a mineral for maintaining normal blood pressure and heart function. And so the inclusion of bananas can help prevent high blood pressure and protect against atherosclerosis, which is basically atherosclerosis is like when you have inflammation in the arteries and they constrict and oftentimes cholesterol buildup can occur because of that so that's really important a second cardiovascular benefit from bananas involves their content of something called sterols. So bananas are there's no fat food, but one type of fat they do have are small amounts of these compounds called sterols, like saitou sterile campus sterile and stigma sterile and they look structurally similar to cholesterol. So when we say sterile people might not think of cholesterol, but cholesterol is a type of sterile as well. They're they're all similar compounds month. Literally, so these plant sterols because they are structurally similar to cholesterol. They can block the absorption of dietary cholesterol. So if you if you have some cholesterol in your meal, but you also have eaten a banana along with it though sterols and the banana May block the absorption of some of that other cholesterol from your meal off then that helps keep your blood cholesterol levels in check. Wow, so that's and that's another you know, really important aspect of having plant Foods in the diet as a lot of plant Foods off kardos have sterols and them as well and that's like avocados are known to be a cholesterol-lowering food because of their sterile content and then a third type of cardiovascular benefit from banana juice is has to do with their fiber content. I probably talked about this before but bananas are really good source of something called soluble fiber which fiber dissolves in a Fluidity Waters that are you know, from foods that are coming through your digestive tract. So it forms kind of like a gel in a way. I always like to use an example of cuz people can use this visual what happens when you put chia seeds with water. They they absorb the water and they jell up they make like a almost like a gel and so that's happening in your intestine when you have soluble fiber in your diet. So bananas have a lot of soluble fiber and what that does is it attracts cholesterol to it and it also attracts even some of the carbohydrates and sugars from the meal. It tracks them into that gel and then they don't get absorbed into your bloodstream. They stay in the stool and then they are eliminated through the bowel movement rather than actually having them into the bloodstream. So that's how soluble fiber manages our blood sugar and manages our cholesterol levels. So that's you know, some bananas man. They're really good. Yep. Really good, they also so something really interesting with athletic performance that I found information on about the banana. So the name of a unique mix of vitamins minerals and the low glycemic carbohydrates making them a favorite fruit among athletes a study of distance cyclists found that eating the equivalent of about one half of a banana every 15 minutes of a 3-hour race was just as good as keeping energy levels steady as drinking an equivalent amount of a carbohydrate and minerals from a processed
