Family Nutrition: What’s the deal with Multivitamins?

This is definitely one of my top ten questions from clients and frankly it’s a hard question because there isn’t a generic answer.  The internet and such stores as the Vitamin Shoppe and GNC continue to place a lot of focus on vitamins and minerals and some of my clients swear by their regimen.  I’ve even had some clients tell me they can tell a difference within hours of taking certain supplementations.   Since this is a subject I try to tame my responses too, I was very glad to see the article “Multivitamins, So Many Types, So Many Labels” by Melinda Beck in the Wall Street Journal published June 21, 2001. 

Did you know that the multivitamin is the number one dietary supplement producing $4.8 billion back in 2008 and that one third of American’s take multivitamins religiously?  As Melinda points out there are many different varieties of multivitamins yet there is no specific formulation that specifies what a multivitamin should look like.  This becomes confusing especially when looking at wide ranges of ages and co-morbidities.  A multivitamin can be a mixture of any vitamins and minerals and the only specification is that it has to list ingredients on the label.  What’s more, 10 of 38 multivitamins tested by ConsumerLab showed that ingredient listings didn’t jive with actual amounts in the bottle.   Price was also not a factor as some of the multivitamins that sell for ten cents a day performed better than vitamins that sell for fifty cents a day.

There have been many studies on the use of multivitamins.  Some cited in this column show associated benefits, some show insufficient evidence that multivitamins decrease death from cancer or cardiovascular disease. 

At the end of the day, there are definite populations that require an increased vitamin or mineral consumption.  Pregnant woman, infants, elderly, or specific chronic conditions require an increase in specific vitamins and minerals and if you are not able to get the recommended amount from food, this is when supplementation should occur.  As far as a generic multivitamin I’m not completely sold it is a necessity.  I  agree it should be recommended when an individual has poor eating habits or does not eat enough whole fresh foods, but for the most part if you are eating well rounded meals, my request will be to review labs and make individual recommendations from there. 

I’ll close with a comment from Dr. Coates, of the NIH, who says based on the best evidence, "If you are taking multivitamins, there is no reason to stop, and if you are not taking them, there is no reason to start. You are unlikely to harm yourself, whatever you're doing." Pretty compelling isn’t it? 



Always choose whole foods first as a source of vitamins and minerals

I take supplements for Vitamin D, B12, and folate which I am deficient in. I really try to focus on eating a lot of fresh vitamins and minerals to obtain the rest of the minerals and vitamins I need,

Food Trends: A note about Stevia (zero calorie sugar substitute)

We’re all on the lookout for that sugar substitute that withholds calories, tastes good, and is natural and safe.   Recently I was asked what my thoughts were on Stevia?   Well to tell you the truth I didn’t have many thoughts on the product because basically I didn’t know much about it, except that in my mind it was a zero calorie product that could be substituted for table sugar.   I put this thought in my attic with the hopes of getting more acquainted at a later time. As I get myself more familiar lets start with the derivation.   Stevia is an herb that comes from South America and has been used by the Guarani Indians of Paraguay for over 100 years.   This is advertised on the Stevia website along with a statement that it provides zero calories because the body doesn’t metabolize glycosides from the leaf or processed forms.   Essentially Stevia is absorbed by the gut and broken down into Stevol which is excreted from the body as a waste.   Th...

Food Trends: Plant vs. Animal Protein

In my practice I see a lot of vegetarians who have a lot of questions about the types of protein they eat.   In case you need a refresher, animal proteins are proteins derived from meat, dairy, and eggs.   Plant protein is derived from nuts, seeds, beans, legumes and soy.   Most animal proteins are higher in saturated fat as well as cholesterol which have been proved to increase risks of arteriosclerosis, a precursor to cardiovascular disease.   A lot of the general public, not just vegetarians, are starting to focus on decreasing intakes of animal proteins and focusing on plant sources to decrease total calorie, fat, and cholesterol intake.   It’s important to know that most generally healthy individuals only need .8 grams of protein per kilogram of body weight.   Basically this means that a 150 pound man or woman requires about 54 grams of protein in an entire day. Protein is made from amino acids.   Although there are many amino acids, ther...
