Dietary supplements: No positive health effects

Loading ....


In recent decades the number of people taking dietary supplements and vitamins especially in developed countries has grown.
In total, global sales exceed 123 billion dollars each year.
The problem is that there’s growing evidence that many of the supplements and vitamins have no proven positive health effects.
Al Jazeera’s Science Editor Tarek Bazley reports from San Francisco.

  1. I can easily find a hundred doctors with better qualifications that Dr. Swartzberg has who completely disagree with him. In a sense, what he has to say about vitamins is true. Very few people in developed countries need to take vitamins because the great majority of us get every vitamin we need in our food. There are, however, many who have such a rotten diet, usually by choice, that a vitamin supplement most certainly does help them. If it didn’t, noe of us would need any vitamins at allIn other words, Dr. Swartzberg is not very logical. He demands a huge study to determine basic facts that must be true.

    And where minerals are concerned, this applies even more. Even in developed countries, a very sizable percentage of the population simply does not receive the minerals they need, by Dr. Swartzberg’s own standards, in their diet. This is an undisputable fact. So if you aren’t getting what even Dr. Swartzberg says you need, then how can a supplement of that deficiency not help?

    Doctors like him seem to have forgotten the history of medicine. Many, probably most, of the miracle drugs we had came from plants, and people were using these plants medicinally for hundreds to thousands of years, yet modern doctors said they didn’t help, that they had no science behind them. But when the studie swere finally done, after far too many years in many cases, they proved the doctors wrong, and suddenly the doctors said, “We knew this all along. We just wanted to be sure.” Yeah, right.

    This is also the same group of doctors who said there was no scientific evidence that cayenne pepper could often work near miracles when someone had a heart attack, even though there were hundreds of cases, many at hospitals, where this happened. Now it’s been proved that cayenne pepper can not only save the life of a great many heart attack victims, but very often works far better than any of the so-called “scientifically proven” drugs the medical field has been using for decades.

    I’m all for science, but science, like every other field, has one massive fallibility, and this is the facts that scientists are just people, and are wrong just as often as any of us.

  2. It’s their money, if they don’t want to do their research and squander their earnings then that’s their problem.

  3. ‘…I don’t need the research study to tell me’. WTF? It’s like that nut-bar at the Republican congress, ‘I know Obama is a Muslim because I feel he is’.
    Science people, science.

  4. ‘Noticing differences’ may just be the placebo effect

    1. This is another area where doctors are ridiculously foolish. It most certainly has been scientifically proven that many, many people not only feel better because of the placebo effect, but a huge number are actually healed by it. If you’re healed, what difference does it make that the placebo effect was the cause? You were still healed, and doctors have absolutely no idea how this happens.

      But purely because they can’t explain it, they dismiss it completely. This attitude is completely unscientific. It’s ego and arrogance to an unbelievable degree. But, of course, they’re always right and we peons are always wrong. At least until their studies prove we were the ones who had it right. Somehow, when this happens, they take the credit.

  5. Next thing we know we will be buying bottled water.

    1. If you lived where I do, you’d pay a hundred dollars for a single bottle of unpolluted water.

  6. Yeah, a lot of people just pop pills as a habit. It provides a psychological edge, i guess.Good marketing and conditioning from the pill provider part. Poor governance on the importance of public well fare on the other side.

  8. childre that age do not require vitamins

    1. You’re full of something browner and slinkier than any vitamin. Children that age, and much younger, are dying or going blind all over the world for lack of vitamins.

    2. -Studied medicine from a donkey shed in the dessert.

  9. This guys from NZ yay!

    1. A lot of Al-Jazeera reporters/journalists are, don’t know why… but they are all good at their job 🙂
