Can vitamins increase risk of cancer ?

Yes

Vitamins are absolutely essential nutrients and vitamin deficiency causes various illness.

But a high dose of vitamin, far too much than needed by the body, is also bad.

Everything in moderation is good. Even an abundance of a good thing is bad.

It is similar to food. Lack of food would cause starvation and even death in the extreme. But too much of food causes obesity and other health problems. Same principle applies to vitamins.

A Cochrane review looked at the ability of vitamins to prevent lung cancer. The review concluded that there is “no beneficial effect of supplements for the prevention of lung cancer and lung cancer mortality in healthy people”

Worryingly, the review also found that the following:

Vitamin A supplements increase lung cancer incidence and mortality in smokers or persons exposed to asbestos”.

Vitamin C increases lung cancer incidence in women.

Vitamin E increases the risk of haemorrhagic strokes.

So if you are having a healthy balanced diet, be careful with vitamin supplements.

Can a Vegan diet help weight loss?

Yes, Vegan diet can help weight loss.

Lot of diets promoted by Magazines, Social Media Influencers and Celebrities do not have strong scientific evidence in favour of them.

A scientifically sound trial published by the medical journal JAMA ( Journal of American Medical Association) recently, found the Vegan Diet helped weight loss and promoted Good metabolism.

The trial involving 244 participants found that over 16 weeks, body weight decreased on average by 5.9 kg in those having a Vegan Diet. That’s very impressive!

Before you rush to relish your burger or steak , please note the evidence for beneficial effect is very much in favour of plant proteins than animal proteins.

Is whole milk harmful ?

In years gone by , many viewed milk as a wholesome healthy food. Government encouraged consumption of milk by providing free milk.

But in recent years, milk is viewed with suspicion.

Vegans shun milk and diary products.

Perhaps the Vegans got it right all along at least as far as whole milk is concerned.

A very large study involving 168 153 women and 49 602 men was published recently in British Medical Journal. The study found that whole milk intake is associated with increased risk of death from heart problems and from some cancers such as lung cancer, ovarian cancer, and prostate cancer.

Interestingly “Cheese and yogurt intake was NOT associated with increased risk of death”.

The risk was also less with “skimmed or low fat milk”.

Dietary advice: take it with a pinch of salt

Official dietary advice as well as various “Diets” promoted by various celebrities tend to be very prescriptive. They often give the impression that the evidence behind everything they promote is very clear cut.

But truth is far more murkier ( I might say more “mish mash “).

A new study analysis of old data comes to a different conclusion about “red meat”. This is in fact not surprising as the evidence for various Dietary guidelines and “Diets” are not usually robust and watertight and involves lot of assumptions.

What is the take home message:

Eat “everything you like” in moderation and try to make it as balanced as possible with substitutes for things you avoid !!

Avoid processed food as much as possible and eat fresh.

Don’t be surprised if the next two studies on this topic reach three different conclusions.
