Preserving Immune Function in Athletes With Nutritional Yeast

Preserving Immune Function in Athletes With Nutritional Yeast


[Music] moderate exercise improves immunity and decreases illness rates by far the most important finding that is emerged from exercising my knowledge II studies over the past two decades is that positive immune changes take place during each bout of moderate physical activity over time this translates to fewer days of sickness with the common cold and other upper respiratory infections we’re talking at 25 to 50 percent reduction in sick days and then one drug or supplement that can do that and it doesn’t take much let kids run around for just six minutes and you can boost the numbers of immune cells circulating their blood stream by more than a third and at the other end of the lifecycle exercise may help prevent age-related immune decline sedentary women in their 70s may have a 50% chance of getting an upper respiratory illness during the fall season every year but walk a half hour a day and your risk is down to 20% the runners in the group got it under 10 it’s like five times better immune system now while regular physical activity improves immune function and lowers upper respiratory infection risk sustained and intense exertion may have the opposite effect forming a so called j-shaped curve relationship as you go from inactive to active your infection risk declines but hardcore athletes that overtrain may actually put excessive stress in their bodies and increase their risk of infection then you could lose training days your performance could suffer so what can you do well traditional sports medicine doesn’t appear to have much to offer advising athletes to you know don’t pick your nose avoid sick people get a flu shot a new study though found that one can better maintain one’s level of circulating white blood cells after exhaustive exercise by computed consuming a special type of fiber found in baker’s Brewers and nutritional yeast brewers yeast is but nutritional yeast is a nice cheesy flavor I use it mostly sprinkle on popcorn anyway normally two hours after cycling your brains out you can experience a dip in circulating monocytes one of our first line of defense white blood cells but those who had been eating the equivalent of less than three-quarters of a teaspoon a day of nutritional yeast ended up even better than when they started after strenuous exercise but does this increase in immune cells translate into fewer illnesses well let’s try it on some marathon runners in the weeks following the calls bad marathon this is how many runners reported experience upper respiratory tract infection symptoms taking a placebo but if instead they have the equivalent of a daily spoonful of nutritional yeast they cut their rates in half and what’s even more remarkable is that they felt better they asked how they felt on a scale of one to ten people taking the sugar pills were like okay down around four or five but those taking identical-looking capsules of the fiber found a nutritional yeast or up at like six or seven evidently elite athletes tend to normally experience deterioration and mood state during intense training periods before and after a marathon race but sprinkle a little spoonful of nutritional yeast and you may feel less tense less fatigue less confused even less angry and my favorite significantly more vigor [Music] you you
