Benefits of Vitamin D supplements and Omega 3 supplements

Most people assume that nutritional supplements are always beneficial. But it is not always the case.

Paradoxically, the people, who may need the supplements because they don’t have a healthy diet, are the often ones who do not take the supplements !

But people, who usually do not need various supplements, because they are health conscious and have a good healthy diet, are often the ones who take the supplements unnecessarily !

Sometimes Supplements can be harmful. Hence, the need for clinical trials to assess the benefits and risks of various supplements.

So it is interesting to read a trial in the British Medical Journal (BMJ) which looked at Vitamin D and marine derived omega 3 fatty acids supplements. The study looked the effect of these two supplements in preventing Autoimmune diseases.

Autoimmune disease is a type of disease where body’s own immune system misfires and causes inflammation in self-tissues.

Autoimmune diseases, are often chronic conditions and cause considerable misery.

The study published in BMJ looked at Autoimmune diseases, such as rheumatoid arthritis, polymyalgia rheumatica, autoimmune thyroid disease, psoriasis, and inflammatory bowel disease, and all other new onset autoimmune diseases.

This well conducted study used a dummy pill and hence the results are usually expected to be quite reliable.

About 25 800 participants were enrolled in the study and were followed up for an average of about 5 years.

This large study from United States found that vitamin D and omega 3 fatty acid supplementation taken for five years reduces the risk of developing autoimmune diseases.

Are mind numbing jobs associated with dementia ?

Yes.

It’s the principle of “use it or lose it”.

Body muscle strength can be lost quickly if it is not used. That’s why many people try to go to Gym and exercise regularly.

The same principle seems to apply to the brain.

People who are using their brain regularly with stimulating jobs are better off than people who are doing mind numbing jobs when it comes to dementia later in life.

So if your are not using your brain that much in your job, perhaps you need a “brain Gym” outside your work !
