Myth #4: If you don't eat enough healthy foods, taking a supplement will cover your bases.
Truth: A poor diet supplemented with vitamins is still a poor diet. Food remains your best source of vitamins, minerals, antioxidants and phytochemicals that are necessary for good health, and there has been no evidence to date that proves people who take supplements are any healthier than those who don't. Spend a little more time and money on delicious, tasty meals and snacks to meet your nutritional needs instead of supplements. Remember that a supplement is just that—a little extra in addition to wise food choices like real fruits, veggies, whole grains, lean proteins and calcium-rich dairy (or non-dairy) products.
Myself: I rarely remember to take a daily vitamin, but I do feel that it is necessary to take one. Like it says above, spend more time focusing on getting your daily nutrients from the foods you are eating instead of a pill. Another post will be needed on what foods help get the best and most efficient nutrients. Look for that in the near future.
