Every single movement, in fact every single thing we do — from running to catch a frisbee or walking the dog — demands energy, energy from our cells to be precise.  

But the number of aging cells in the body goes up with age. As the aging immune system becomes less efficient, aging, or senescent cells, build up and can drag down healthy cells.  

This can impact our ability to tackle stress or illness, recuperate from injuries, and even learn new things, since senescent cells in the brain can degrade cognitive function.

Did you know that there are more than 10,000 different types of protein throughout the body?  

Amazingly enough, it's true, and these proteins can be found almost everywhere in and on the body, including the hair, skin, bones, tissues, organs and muscles. 

Aside from gut health and metabolic health, protein is involved in a wide range of processes that generate energy, transport oxygen, make antibodies, keep cells healthy and control appetite.

There’s a common understanding that flu (and now COVID-19) season falls during the winter months; summer is all about school closures, outdoor music festivals, beach bashes, and farmers’ market visits. While it is true that viruses like the flu survive better in cold, dry air, you need a strong immune system year-round—even during those sunshiny summer days—because weather doesn’t carry respiratory infections. And no matter what your mother or grandmother told you, the cold won’t make you sick; it could help burn calories.

Although viruses that cause respiratory infections, such as a cold or flu, have a lower survival rate in the air during the summer, you can still get sick. During these upcoming summer months, we want you to be prepared to take care of your immune system with the same ferocity you exhibit during winter.

Vitamin C gets a lot of credit for its immune-support benefits, along with zinc, echinacea and a few other ingredients — as well it should. 

But science shows that protein and amino acids are just as important for immunity.  

Germs. As comedian Rodney Dangerfield would have said, “They don’t get no respect!” 

In fact, before the 19th century, when people were not even aware of germs, hand-washing was just to wash off obvious grime and dirt. 

Since the “germ theory of disease” was developed by Louis Pasteur and Robert Koch in 1861, society has increasingly transformed our view of germs — those we have always lived with and newer varieties to which we have inadvertently given rise — into an “us versus them” War on Germs.
