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.

Does exercise protect you from dementia?

It would be common senses to think that exercise would lead to better physical health and this in turn would protect you from dementia.

But a recent study in BMJ suggests that exercise does NOT have a significant protective effect on developing Alzheimer’s dementia .

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.

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.

Low Carb Diet

High carbohydrate diet can make a person put on weight.

The extra weight can put a strain on the knees and logic dictates that over time this can cause knee problems due to excessive “wear and tear”.

So would a Low-Carbohydrate and Low-Fat Diet help to relieve Pain in Individuals with Knee Osteoarthritis.

Yes, low carb diet can indeed have positive effect on Knee pain.

A study testing the efficacy of two dietary interventions found that low carb diet can reduce pain intensity .

What’s in a name?

The word cancer is a dreaded one. Not without a good reason. Cancer is the number one killer. Even when someone has a good outcome, the cancer journey is torture. Emotional turmoil is immeasurably horrendous.

But many people would be surprised to hear that there exists a category of low risk cancers. “Low-risk Cancers are cancers which usually don’t kill; These Cancers are found either incidentally on scans performed for some other reasons or found as part of routine cancer screening.”

Because they are not deadly, Should the patients diagnosed with low-risk cancers be spared the dreaded label of cancer?

Should low-risk cancers be labelled something else and the word cancer used only for the “serious” high-risk cancers ?

Personally, I do not agree with renaming of the low risk cancers..Others disagree

Joint the debate at the BMJ.

Can Turmeric control cancer ?

Turmeric powder

 

Turmeric is an orange coloured spice widely used in Indian dishes.

Turmeric has been used in Indian traditional medicine (Siddha and Ayurveda).

Turmeric has anti-inflammatory and anti-Cancer properties when tested in laboratories.

Remember – a potential to be beneficial (based on lab studies) is not the same as being proven to work in humans. Lot of substances which are promising in the laboratory eventually turn out to be useless in humans.

If you search PUBMED database- which is an online database of scientific papers- you will find hundreds of papers pertaining to medicinal use of turmeric and its key ingredients such as curcumin. But unfortunately among the many hundreds of published papers, there are very few human trials which have explored turmeric as a anti-cancer treatment.

Inspite of the positive anectodal reports on various internet sites, the available scientific evidence for use of turmeric as an anti-cancer treatment is very spare. ( references below).

Hence it is not worthwhile using turmeric as a cancer treatment.

If you do like Indian dishes, use turmeric as a spice in your normal diet.

But do stay away from the supplements which are sold with health claims.

Low carbohydrate diet

The advocates of low-carb diet received a scientific boost recently.

An American trial, published recently in the British Medical Journal, compared the effects of low-carb-high-fat diet with high-carb-low-fat while keeping total calories and protein intake constant.

This elegantly done trial shows that carbohydrates are bad for weight loss. A diet with a combination of low-carb-high-fat content was the winner in this trial and it promoted energy loss and helped maintain weight loss.

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?

blur calcium close up dairy

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.

Can alcohol cause cancer?

pexels-photo-533257.png

Can alcohol cause cancer?

Yes,  worldwide, 1 in 20 cancers are attributed to alcohol .

How much drinking causes cancer?

“Even modest use of alcohol may increase cancer risk, but the greatest risks are observed with heavy, long-term use”

“The more that a person drinks, and the longer the period of time, the greater their risk of development of cancer, especially head and neck cancers”

Are light drinkers at risk ?

Risk of cancer is present at  even at low levels of consumption.  Hence, the World Cancer Research Fund/AICR makes the following recommendation: “If alcoholic drinks are consumed, limit consumption to two drinks a day for men and one drink a day for women.” They also recommend that, “for cancer prevention, it’s best not to drink alcohol.”

Is wine less risky than spirits?

No,  the risk is present “regardless of the specific type of alcoholic beverage (ie, beer, wine, or spirits/liquor)”

Which cancers can arise due to alcohol?

Alcohol is causally associated with Mouth, Throat, Gullet, Liver, Breast and Bowel cancers.
