Does alcohol increase of breast cancer?

Yes, Alcohol does substantially increase the risk of Breast cancer.

Very few people seem to be aware of the risks.

Previously it was thought that heavy drinking is responsible for harmful cancer effects.

But studies from U.K and U.S.A have subsequently shown that even light to moderate drinking can increase the risk of breast cancer.

A very large study involving more than 1,250,000 middle-aged women in the United Kingdom ( enrolled in the Million Women Study) showed that “Low to moderate alcohol consumption” in women increases the risk of breast cancer and certain other cancers.

In a study involving more than 88,000 women from United States, also showed that light to moderate drinking increases the risk of breast cancer.

So keep counting the alcohol units during the festive time.

Crowdfunding expensive stem cell therapies

Crowd fund metaphor

If you have come across a desperate request to crowdfund an expensive stem cell therapy, read this well researched BBC article before you contribute.

Hope is a powerful driver particularly when someone is facing immense difficulties in life. Human beings have a natural inclination to fight against all odds and it seems to be inbuilt in our DNA and psyche.

But not all promising treatments do help desperate people searching for a cure.

Is processed red meat bad for health?

Yes, red meat especially processed red is bad for health.

In a study published in BMJ, red meat was implicated in causing more deaths.

The authors from Harvard, advocate replacing red meat with equivalent amounts of other protein sources, such as nuts, poultry, fish, dairy, eggs, and legumes, and whole grains and vegetables.

Are Vitamin and Food supplements safe and helpful?

A British man recently ended up needing a liver transplant after taking green tea capsules. (1).(2).

Many people do not realise that supplements can be useless or even harmful. 

Firstly, Dietary supplements may not always be helpful. Even though the Public Health team in England recommend vItamin D supplements, a large study published recently  – found that Vitamin D supplements do NOT prevent fractures or falls in General population. (3) (4).

Secondly, Dietary supplements can be harmful. For example , a cancer prevention trial involving 35,533 North-American men reported that  “Dietary supplementation with vitamin E significantly increased the risk of prostate cancer among healthy men”. (JAMA 2011; 306: 1549).  Another cancer prevention trial in Finland involving 29,133 male smokers unexpectedly found a “higher incidence of lung cancer among the men who received beta carotene dietary supplements”. (NEJM 1994;330:1029 )

On the other hand, Vitamin are essential nutrients. Vitamin deficiency can be severely harmful to health. Vitamin D deficiency is common in colder parts of northern hemisphere. Vitamin D supplements are used in treatment and prevention of osteoporosis (5). Vitamin B12 deficiency is common in Vegans and Vitamin B12 supplements are used. (6).

So there is no clear cut answer ….

Always consider the possibility that “dietary supplements may actually have harmful as well as possible beneficial effects”.

Can milk cause cancer?

A vegan group’s recent advertisement claimed that “cow’s milk contains 35 hormones, including oestrogen … some of these are linked to cancer”.

Advertising Standards Authority (ASA) in U.K banned the vegan group’s advert  as it found the groups claims misleading.

Does the evidence stack up?

First of all, I have to emphasize that “Human Mothers milk” is the best nutrition a new born baby can have…even though it might have various natural hormones.

But “mass produced diary milk” is a different matter.

A large observational study from ” Central Sweden”  found that “High milk intake was associated with higher risk of death and higher fracture incidence in women”. The paper was published in the prestigious BMJ journal in 2014. I suspect the substances used in mass production of diary milk might be the culprit rather than natural milk itself.

So the jury is out on this question. In the mean time, moderation is the key as Cows’ milk does contain many beneficial substances.  Switching to sugary, fizzy drinks or other artifically produed milk alternatives is not sensible either.
