Consumers beware. The snake oil salespeople of yesteryear never left the building. They just left the oil behind and moved on to selling nutrition supplements and other products that are not based on science. These skilled salespeople introduce health fears into your mind and then try to sell services and products to allay these newly created fears. They make unrealistic promises and guarantees.
To avoid falling for one of their shady schemes, you should be leery of infomercials, magazine ads, and websites that try to convince you that:
Most Americans are not adequately nourished.
Everyone needs to take vitamin supplements.
You need supplements to relieve stress or give you energy.
You can lose a lot of weight in a short amount of time.
Their products can produce amazing results and cure whatever ails you.
Your behavior is caused by your diet.
Herbs are safe because they are natural.
Sugar will poison you.
A hair sample can identify nutrient deficiencies.
Your MD or RD is a quack to whom you should not listen.
There is no risk, as there is a money-back guarantee. (Good luck getting your money back!)
