In this post, I am reviewing a major study on multivitamins and providing a commentary on the study by Barnard. The first research publication below examines the use of multivitamins in nearly half a million individuals and assesses whether the vitamins increased their life span. Multivitamins are defined as any supplement with 3 or more vitamins. The findings were multivitamins did not prolong life span.<\/p>\n\n\n\n

In his follow-up commentary on the research (Article 2), Barnard suggests that this study reinforces the need to focus on eating plant foods rather than using supplements, as that approach may offer more significant health advantages and longevity benefits. However, he does not fully analyze this study, which is fraught with holes.  So, let\u2019s review!<\/p>\n\n\n\n

What are just a few of the problems with the study? First, they relied on self-reported multivitamin use. This reporting is unreliable (as the authors admit) and only tells us a little, except that people report <\/em>using vitamins.<\/em><\/p>\n\n\n\n

I then ask: <\/em>What about the quality of the vitamins? Which brands? Did they have additives and sugars? We can assume that most of the vitamins people used were like the Centrum brand, which are loaded with sugar, hydrogenated palm oil, and other cheap synthetic vitamins found at the local drugstore.<\/p>\n\n\n\n

I also scanned the article for details on the type of vitamins but found none. Did they have cyanocobalamin instead of methylcobalamin or folic acid instead of folate, two synthetic forms of vitamins that should not be used? Or did they include a-tocopherol for vitamin E instead of four tocopherols and four tocotrienols? Did they assess whether the participants needed some vitamins and not others?<\/p>\n\n\n\n

Pesticide applicators comprised much of the cohort<\/strong>.<\/p>\n\n\n\n

Among the 390,000 participants, a significant portion, upwards of 57,000 (plus 42,000 spouses), were pesticide applicators. This raises a crucial question: could chronic exposure to pesticides affect mortality? Is this a potential health risk that cannot be mitigated by a multivitamin alone? The authors also acknowledge some limitations in the study design, further emphasizing the need for comprehensive research in this area.<\/p>\n\n\n\n

Back to Barnard\u2019s commentary on the study: There is no question that using nutrient-rich plant foods is healthy. However, see my critique of Barnard’s analysis below.<\/p>\n\n\n\n

I agree that a nutrient-dense diet is ideal, but this is not an either-or argument. Nor is it an argument favoring a plant-based diet ONLY, which is Barnard’s argument. An avowed vegan, he founded the Physicians Committee for Responsible Medicine. It sounds innocuous enough, except it promotes ONLY plant-based diets, especially veganism. What about people who live around the world, like the Inuit of Alaska and Greenland, whose traditional foods are fat and protein from fish and mammals, and who would have to ship in enough legumes, grains, vegetables, bananas, and all other plant foods in order to be vegans, none of which grow locally? Or the Massai of Kenya and Tasmania, whose traditional diet has nourished them for millennia by drinking and eating almost only raw milk, meat, and blood. <\/p>\n\n\n\n

Indigenous peoples of the western hemisphere did just fine with diverse plant and animal diets before contact with European settlers. As did the Celts, the Irish who thrive on salmon and seaweed, the traditional foods of Ireland. As a clinician and long-time vegetarian (who has also eaten as a carnivore), I embrace all types of diets for people that are geared to what they need personally (except the Standard American Diet, the  SAD one, of course); this is my \u00abbeef\u00bb with such myopic US-centered ideological analysis.<\/p>\n\n\n\n

For diet and nutrition to be truly helpful in preventing and treating disease and decreasing mortality, they must be personalized to the individual’s needs and include lifestyle, genetic, and cultural factors. This approach respects each person’s unique needs, acknowledging that there is no one-size-fits-all solution in nutrition.<\/p>\n\n\n\n

Finally, the overall message of this research isn\u2019t helpful: Don’t take vitamins; they won\u2019t help you live longer; in fact, you will die sooner.<\/em><\/p>\n\n\n\n

I give this a thumbs down for both research and commentary.<\/p>\n","protected":false},"excerpt":{"rendered":"
