health food supplements are one of the hottest selling products on the market these days. Their total consumption values billions of dollars in the U.S. alone. Recent studies show that more than half of all adults in the U.S. consume health food supplements in different forms such as tablets, capsules, powders, soft gels, gel caps and liquids.
Increased consumption of healthy food supplements can be attributed to public awareness of health issues and improving standards of living in our society. Many studies have shown that there is a close link between health and nutrition. Insufficient supply of nutrients can weaken our body defense mechanism, causing medical problems from common diseases to more severe disease in the long run.
There are different kinds of health food supplements, including macronutrients (amino acids, proteins, essential fatty acids), micronutrients (vitamins and minerals), enzymes (digestive enzymes and antioxidant enzymes), probiotics (beneficial bacteria in the gut), and herbal supplements. These supplements have unique functions in our body. They are either essential for life and good health, modulate our immune system and help with liver detoxification, digestion, mental clarity, etc.
Many people believe that there is no need to consume health food supplements as long as you have a healthy lifestyle and eat a balanced diet. While this May be true, the fact is maintaining a healthy lifestyle and proper nutrition is difficult to achieve by many people.
Over the past few decades, the green revolution has changed the farming world. We use more chemical fertilizers and pesticides to grow food in order to increase harvest and shorten the growth period. As a result, soil nutrients and the population of beneficial soil bacteria are depleted rapidly, and produce we grow today contain less micronutrient than before.
