Many people are looking for a magic bullet to cure their ills. If only a pill could be invented without side affects! Billions of dollars are spent annually for the panacea that doesn't exist. Supplement companies easily prey on the ignorant in the same way "snake oil" salesmen did in wild, wild west. Now the names are exciting and the packages are slicker.
Only a minority of people require diet supplementation. Yes, strict vegetarians need B12 supplements but not much else. A multi-vitamin can correct any holes in a vegetarian diet. Supplement companies are unnecessary and if people would ask a few questions the lie would be exposed and the victim would save some jack $$$.
One myth I've heard from a popular "shake" company is that supplementation is needed because of soil depletion. That simply is not true. The soil in the United States still produces healthy fruits and vegetables. The real problem is people are eating the wrong foods! A $3.99 daily shake is not the healthiest meal of the day - a large salad with romaine, red cabbage, spinach, carrots, broccoli, cucumbers, radishes, and sunflower seeds is!
There is no easy way out of obesity and there are no shortcuts to a healthy life. Eating a diet of fresh fruit and vegetables is the best way to improve your health and to drop unwanted pounds. You can't shake your way out of it!
