Health problems in middle age

A recent British study reports that nearly a third of middle-aged adults have at least two Health issues.

This is very a depressing statistic.

Lot of people seem to suffering from high blood pressure, mental ill-health and back problems.

It’s important that people take time to look after themselves even if work and life in general is stressful.

It is also important to note that COVID affects people with underlying health issues much more badly.

On the other hand, middle aged people who have health issues should not despair. They are not an exception and think of themselves as very unlucky.

They can see that lots of other people are also suffering. They should get on with their lives and make it better.

This may sound a bit odd at first glance. But some people do find it reassuring to know that lots of other people are also suffering with same health issues.

For example, Some of prostate cancers patients are relieved when they learn that hundreds of thousands of people are out there, living for many years, after a cancer diagnosis. They are not alone.

Cancer Research U.K. website says this: “An estimated 280,500 men who had been diagnosed with prostate cancer between 1991 and 2010 were alive in the UK at the end of 2010”

Is drinking alcohol within guideline amount safe ?

No !

It would be a shock for many to hear that “No amount of alcohol is absolutely safe”.

A team at Imperial College London analysed MRI scans of heart, brain and liver of people who drink alcohol. They found that higher alcohol consumption was related to smaller brain, weaker heart and fatty liver.

They reported that “there is no ‘safe threshold’ below which there were no toxic effects of alcohol.

Previously other studies have also reported that there is no safe limit for alcohol!

In 2018, a Lancet study reported that the risk of death and risk of cancers increased substantially with increasing levels of alcohol consumption; and there was no safe limit below which there was no risk.

The message is “Avoid alcohol”

If you can’t, then atleast drink as little as possible.

Selenium can be harmful for Skin cancer patients

Nutritional supplements are often tried to prevent cancer. But well- designed rigorously conducted clinical trials have NOT shown any benefit in prevention of many cancers.

Selenium was suggested as a preventative supplement for skin cancer.

A clinical trial compared Selenium against placebo in United States. The results were disappointing.

Selenium supplementation was found to be ineffective at preventing Skin cancers.

To make matters worse, Selenium was found to Harmful and increased the the risk of getting some skin cancers such as squamous cell carcinoma.

Cancer and COVID-19

Cancer patients, as expected, did badly during the 1st wave of the COVID-19 pandemic

Data presented at ESMO ( European Society of Medical Oncology) shows that Cancers had – higher rates of Hospitalisation, higher risk of Complications and increased risk of Death.

Elderly cancer patients on the whole did very badly but surprisingly cancer patients under age of 50 did far worse than their peers without cancer.

Can Hair dyes cause cancer?

Yes, there is a possible increased risk of some types of skin and breast cancer as well as ovarian cancer.

Permanent hair dyes are widely used. A recent study published in BMJ suggests that use of Hair dyes might be risky.

This large study from United States enrolled 117 200 women in the Nurses’ Health Study. The women reported on personal use of permanent hair dyes, and were followed for 36 years. So overall it is a high quality observational study.

Read the full paper and Caveats at the BMJ website.

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?

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.
