Eating Certain Cheeses Keeps Older Folks Healthy

The newest news is that some cheeses can boost immune systems in older persons. Here's how it works.
The immune system deteriorates (along with other things) as we grow older. This age-related deterioration is called "immunosenescence" and effects our ability to fight disease. This means that we become more susceptible to infections (like the flu or a bladder infection) and we have more trouble fighting illness off when we get sick.
Some cheeses, yogurts, and milk carry something called "probiotic bacteria," called "probiotics" for short. Probiotics have long been known to boost the immune system. Now researchers have discovered that probiotics actually fight immunosenescence, the very thing that makes elders more susceptible to disease.
Aged cheeses made from raw milk carry probiotics developed during the fermentation process. Cheddar and Gouda are the best sources that are readily available, more aged is better. One slice, 3-4 ounces daily, can provide a big boost to your immune system.
Yogurts also carry probiotics but it's important to read the label because some yogurts sold these days have been pasturized, killing the good probiotic bacterias you need. The label should tell you if the yogurt contains live natural cultures.
Kefir is another aged milk-related product that develops probiotics. It's made from the whey leftover from churning butter.
And finally, food choices with probiotics many don't know about, are unpasturized sauerkraut, brine-cured olives, and sour pickles. Usually this type is found in the regrigerator section of the supermarket. Remember..unpasturized. The pasturizing process kills the probiotics.
Just in case you're bored...
