Happiness comes from being healthy

Being a doctor I come across various reports. There are claims and counter claims. Just few days back I read that taking calcium supplements and vitamin D is not helpful in preventing osteoporosis or colon cancer. My mother has just attained menopause and for last one year on and off I had started her on calcium supplements. She is confused whether to continue the calcium tablets since they have also reported increased incidence of kidney stones in people taking calcium supplements. On the other side there is my aunt taking vitamin d and calcium supplements for 15 days in a month since last 3-4 years and she has had tremendous symptomatic benefit with the treatment and she says she will continue with her tablets.
My stand on this is neutral as of now. May be another research group will come with evidence that it is indeed beneficial. So if ur symptomatic , please take supplements, that is on an individual basis the decision will have to be taken. As a vitamin supplement to be taken by everybody is to be discouraged in view of the present evidence. The article was published in NEJM , areputed journal.
All said and done the time tested method to remain healthy is to eat frugally, if i have used the word rightly, I intend to report that scientists have found in animals atleast that if u restrict ur diet , u can live 50% more and also with less disease. Age related diseases like osteoarthritis, cancer, diabetes , hypertension are found less commonly in people who eat sensibly.
In fact all the above has solid scientific hypothesis.
It has also been found that mitochondrial DNA gets mutated at a faster rate and the amount of mutations in it is related to ageing and age related diseases. Mitochondrial DNA is also responsible for digesting sugar and generating energy. So u eat more, u put more stress on mitochondrial DNA and it is damaged. There r lot of other arguments, but I end by saying that u can be happy only when u r healthy. Health requires common sense approach. Eat sensibly Eat Healthly. Prevent diseases for " Prevention is better than cure".
