Does It Matter What I Eat? What Vitamins Do For You

It just doesn’t make any sense.
 
The guy at the end of the office ended up on the receiving end of a Greenpeace whale rescue the last time he was on the beach. But he is always on a diet. Ask a waif what she eats and it’s along the lines of, “Burgers, junk food in general. Oh! and lots and lots of yummy chocolate. Got one of those metabolisms, I never exercise darling.” Right, but you still have to wear wide shoes to stop you falling down drains.
 
Life is not fair…and people lie.
 
But even if some people’s metabolisms seem to process anything that’s thrown at them while others among us put on weight just talking about food there is far more to diet than calorie counting and weight loss.
 
Console yourself with the fact that the waif with a bulk discount deal from Cadbury’s may well have all kinds of disasters waiting to happen as her body lacks nutrients that will keep her fit and healthy down the line. It may be that if she did try to exercise she’d find out that being in shape is different to being the right shape.
 
Of course you need to be sure you are not eating too much. But it is not just quantity that matters. Quality matters too. In terms of your diet that means you need the vital nutrients – that means vitamins and minerals. These will help you to fight illness and can increase life expectancy. They help your body carry out all the chemical processes necessary for it to stay healthy.

Other foods also contain vital nutrients, such as dairy products being rich in calcium, so a varied and balanced diet is important.
