I have a few acquaintances that have- what I view to be- a strange habit. These people attempt to live a "healthy" lifestyle. They eat healthy, exercise and try to avoid unhealthy habits like smoking and drinking. That is not so strange.
What I find strange is that they will only drink distilled water and take several different types of vitamins and minerals like Vitamin E, Curcumin and all kinds of others I never even knew existed. They have the same water in their taps that we do, but I don't understand the idea behind drinking the distilled water to avoid one thing just to have to take a pill form of these vitamins and minerals in order to get them.
Personally, I think minuscule exposure to whatever "impurities" may exist in the water can be a good thing for your body. Plus, there are all sorts of filtration systems that can remove unwanted impurities and still provide the natural minerals in the water.
I prefer to get my vitamins and minerals by eating the right foods and maybe taking a pill form of whatever I think my body may be lacking as needed. I also can't help but notice that these people have no less health problems than anyone else and that they tend to look unhealthy, pale and even unhappier than most people. I'd rather enjoy my life, enjoy my foods in moderation and enjoy my water straight from the tap. What about you?
