NASA: Omega-3 Intake May Help Prevent Bone Loss

May 19, 2010 by  

NASA: Omega-3 intake may help prevent bone lossSeveral NASA-sponsored studies published in the May issue of the Journal of Bone and Mineral Research indicate that omega-3 fatty acids found in fish oil capsules can help prevent bone loss commonly associated with osteoporosis.

The organization undertook the research because bone density loss is one of the most harmful long-term effects that the weightlessness of space has on astronauts.

For the study, a research team recruited 16 subjects to take part in a 60-day bed rest trial, where the effects of weightlessness were simulated. At the point of follow-up, participants who received high levels of omega-3 fatty acids experienced less bone loss than respondents who were given a placebo.

In light of the findings, the investigators analyzed the diet and incidence of bone loss of a group of astronauts who took part in four-to-six month spaceflights. They concluded that those who consumed more fish lost less bone mineral during their time in space than those who consumed a diet high in other forms of protein.

"These results are very exciting, and provide initial evidence that nutrition may be a key factor in mitigating bone loss in astronauts," said lead author Scott Smith, a nutritionist at NASA’s Johnson Space Center.

    I’m glad to hear about this. I’m a big coffee drinker and apparently this take its toll on the calcium in your body. From now on I will double my intake on omega-3. Is any one out there with the same problem?

    Yvan, I wasn’t aware that coffee could act as a calcium drain. People who suck down lots of pop are setting up themselves for medical miseries they can’t afford. Sugar and sugar substitutes are poisons. If you drink pop that’s laced with ‘alternative’ sweeteners [aspartame, etc.] it can shut down your pancreas (stevia that isn’t ‘blended’ with other sweeteners is safe). Isn’t it funny how MDs and our government want us to keep swilling down LOTS of pop?
    I’m told that krill oil is an improvement over ‘regular’ Omega-3/fish oil supplements. Here’s to your good health.

    Omega 3 is a great supplement for bones but it alone is not enough. To that end, I would suggest that calcium and vit. D supplementation is insufficient. The body needs more than that to build bone and the underlying issue of why it is not re-building as fast as it is re-moving needs to be addressed. Most supplements provide only a few of the critical constituents necessary to build bone and this is like trying to build a house with LOTS of lumber but no windows, nails or bolts. In fact, if we leave the hormonal system imbalanced, it’s like trying to build a new house with a team that is taking it a part every evening when the work-men go home. This is no way to build a house and no way to build bone. I have found one supplement that seems to have all the necessary vitamins, minerals and even a hormonal balancing herb. This is the most complete one that I’ve found. It’s from some place called Nature’s Rite and it’s called Bone Density Maintenance. I’ve been using it and I’m happy with it.

      Your happy with it. Now that is really a good scientific reason for using it.
