Take a look at your hand. Is that the same hand you had yesterday? A month ago? A year ago? A decade ago? You probably said yes to all, but in reality you’re wrong. Your body is constantly replacing old cells with new cells. Check this out:
Skin cells renew every 27 to 45 days
Blood cells – 60-120 days
Entire Blood supply – 3-4 months
Epithelial cells lining your intestines – Weekly
A new skeleton – every 2 years
There are some which turnover very slowly like nerves, but aside from those you have a whole new body every couple of years, and much is only a few months old.
So that was some interesting trivia, but does it really matter? Yes it does. As your body replaces skin, blood, muscles, organs, etc. they are built from what you eat, so like the old saying You really are what you eat.
If you eat the best foods and take the best supplements then you’re body will become better and healthier day by day. If on the other hand your diet isn’t that good and you don’t supplement, then you’re cells will still renew, but if a nutrient they need isn’t available then it just builds without it, or substuties, or takes it from someplace else, like your bones. Your skeleton is your bodies store for calcium, but your body also needs calcium for muscles to move and for nerves to carry messages between the brain and every body part. In addition, calcium is used to help blood vessels move blood throughout the body and to help release hormones and enzymes that affect almost every function in the human body. So if you’re cells need calcium for more important functions like moving blood, then you’ll rob the calcium from your bones to support your circulatory system, and you’ll be on the road to osteoporosis.
Diseases are often though of as something going wrong, but many diseases can also be the result of a nutritional deficiency. We all know of scurvy, which plagued early sailors, is caused by a lack of vitamin C. Other diseases though there isn’t such a clear connection. Essential fatty acids, like fish oil, are essential for brain health, but there isn’t a disease that is directly caused by too little fish oil, though many conditions can get better with fish oil like postpartum depression, ADHD, anxiety, and others.
So back to where I started, if you eat a healthy diet and take some excellent supplements (Not the ones you get at Costco, the grocery store, or even GNC) your body can rebuild itself with every cell of your body becoming as healthy as it can possibly be. Give it 6 months and you literally will feel like a new person.
