Exercise >>> Immunity

[Guest guest]

Hi folks:

I get Dr. Mirkin's regular email newsletter. He seems to be regarded

around here as a source who is worth listening to. The following is

an excerpt from a recent newsletter. Can anyone suggest where we can

find supporting evidence for this? It seems a bit 'kooky' to me. I

will email them and ask, also. ty

" How Lack of Exercise Shortens Lives

Many recent studies show that people die from inactivity,

not just from aging. We know that as people age, they lose

muscle, their immunities weaken and because of their weakened

immunity, they are more likely to die of cancer and infectious

diseases. As you age, you lose your ability to kill germs because

of lack of muscle. When germs get into your body, you must

make white blood cells and proteins called antibodies to kill them.

Antibodies and cells are made from protein and the only place that

you can store extra protein is in your muscles. When you have

large muscles, you have a ready source of protein to make

antibodies and cells. When you have small muscles, you have a

very limited source of amino acids to make protein, so your

immunity may be inadequate to kill germs. ................ "

If this is true I should be exercising a lot more. And lifting

weights, it seems.
