Do COVID vaccines cause heart inflammation?

July 23, 2021July 22, 2021

Yes

COVID Vaccines have caused heart inflammation in a small minority of people.

But that does NOT mean Vaccines have to be avoided.

The benefits of vaccines are far higher than risk of side effects for vast majority of adult population.

People have not stopped traveling by car because of risk of road accidents. This is because benefits considerably outweigh the risks !

Would COVID Vaccination become mandatory for all adults ?

July 13, 2021July 13, 2021

It is unlikely to become mandatory in most western countries. It almost certainly would not become mandatory in USA, where Vaccination seems to become tangled with highly divisive politics.

But it is not an impossible scenario in European countries.

It is possible that more countries would follow the example of Turkmenistan, which has a policy of “no jab, no job”

Also, it does not have to a direct government policy.

If the governments change the law to allow businesses to demand vaccination proof, then indirectly vaccination becomes mandatory for most people.

Private Businesses and Travel industry may decide to make vaccination mandatory for their employees and customers so as to avoid further disruption to their business.

In countries, such as Israel and U.K., where there is already high uptake of vaccination, a change in Law may not be needed at present.

But if the present surge in infections continue, and variants emerge, Governments may change their approach.

Are many NHS staff reluctant to have COVID-19 vaccines?

June 2, 2021June 1, 2021

No !

Vast majority of health care workers already had the COVID vaccine. Only a small minority have vaccine hestitancy.

A recent study found that about 90% of staff had at least one dose of the vaccine within 2 months of vaccine roll out. That is very impressive.

This study ( published in Lancet Journal) found that vaccines are very effective in reducing infections.

But the study also showed what we know already. Vaccination does not give 100% protection.

Everyone, in particular, health care staff need to continue with other COVID precautions such as masks, distancing and regular washing as advised by Government.

Does breast feeding the baby protect the mother from heart diseases in later life ?

March 15, 2021January 4, 2021

Yes, it can.

A Study published in British Medical Journal found that “A longer length of breastfeeding was associated with a reduced risk of cardiovascular disease”

The study also found that women who had certain pregnancy related complications were also at increased risk of heart disease in later life.

In addition, the study also found that taking contraceptive pills (combined pills) in younger age led to increased risk of heart disease and stroke in later life.

Awareness of these risks would help to take steps to reduce the risk from them.

Does Hand Washing help to prevent COVID-19 ?

February 14, 2021February 14, 2021

Yes,

But the extent to which Hand washing helps is uncertain.

Masks, Social distancing and Vaccination seem to be more highly important than Hand Washing.

Read the very good Guardian newspaper piece on the topic of hand washing.

Obesity kills but is losing weight in old age also risky ?

January 4, 2021December 29, 2020

Losing weight is a New year resolution for many people. There is no doubt that having a normal weight is healthy overall.

But there is always some degree of uncertainty with any health advice and this BMJ paper certainly gives “food for thought”.

Before you read further , you have understand that there are varying degrees of being overweight. BMI ( Body mass index) is the scientific way of looking at body weight issues and it is calculated using height and weight.

Based on BMI, people are usually classified into three groups:

(a) underweight and normal weight (BMI<25)

b) overweight (BMI 25.0-29.9)

There is no doubt that obesity is bad for health. The BMJ paper not supringly found obesity in adulthood increased the risk death.

But, intriguingly, just being overweight only without being obese does NOT seem to have MAJOR impact on risk of death in adults.

Paradoxically, the study found that “weight loss from middle to late adulthood was associated with increased risk of death”

It is large well designed study but nevertheless results of observational studies need to be interpreted with caution.

The message from this study is “do not gain excessive weight during early adulthood“. Losing the excessive weight later on might not undo the damage already done to the body.

Does smoking cause Body pain ?

January 1, 2021January 1, 2021

Yes. Smoking can cause body pain and make you miserable.

Smoking is bad for various obvious reasons including the risk of developing of cancer. As smoking can make you miserable with pain, it’s time to make a new year resolution to stop smoking.

A large study done in UK shows that current and ex-smokers have a higher degree of bodily pain.

The study involved 223,537 people who were surveyed between 2009 and 2013 by the British Broadcasting Corporation (BBC) Lab UK Study.

As it is such a big study, the conclusions do need to be taken seriously.

Definitely another reason for quitting smoking this new year !

Can a Vegan diet help weight loss?

January 1, 2021December 27, 2020

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!

Can Pollution affect your heart?

December 16, 2020December 3, 2020

Air pollution, particularly breathing toxic fumes whether it is from a cigarette or a diesel lorry is bad for the lungs.

Can pollution affect your heart as well ?

Yes, it can.

A large study involving more than 8 million people across 184 major cities in China studied the effect of pollution on heart diseases.

The study reports that “short term exposure to Pollutants in air is associated with increased risk of hospital admissions for major heart problems”.

May be everyone living or working close to major roads or high traffic areas should invest in a good mask !!!

Is red meat bad for heart?

December 6, 2020December 3, 2020

Yes, red meat can increase the risk of developing heart disease.

Scientific evidence for a healthy diet and prevention of diabetes

October 21, 2020October 10, 2020

Simple things in life can be the most difficult; For instance, Regular Exercise and a balanced Diet for a healthy life.

What constitutes a healthy diet is common knowledge. For example eating Whole grains, Fresh Fruit and Vegetables )

But what is accepted as common knowledge is not always backed up by robust scientific evidence .

So it is good to see two scientific papers in a recent issue of British Medical Journal with one paper exploring the role of fruit and vegetable consumption on type 2 diabetes and another paper exploring the role of whole grain foods on risk of type 2 diabetes.

1. One study found that Vitamin C and carotenoids have a protective effect against diabetes ( eg diet rich in citrus fruits, tomatoes , root vegetables such as carrots )

A word of caution to those rushing to buy vitamin supplements from the authors : “fruit and vegetable intake, rather than vitamin supplements, is potentially beneficial for the prevention of type 2 diabetes”.

2. Another study found that “whole grain foods, including whole grain breakfast cereal, oatmeal, dark bread, brown rice, added bran, and wheat germ, significantly reduced the risk of developing diabetes.

Coronavirus re-infection and immunity

October 13, 2020January 1, 2021

Many Viral infections give some sort of immunity to the person infected. For example, if a child has chicken pox, then the child develops immunity to further chicken pox. This immunity can even be life long for many children.

But some viral infections don’t result in significant immunity to further infection. For example, Flu and Common Cold viruses infections do not result in effective long immunity. That’s why flu vaccines are given yearly to vulnerable people.

It was hoped that a Coronavirus infection could result in at least some sort of long immunity to further infections.

A recent report of man who developed Coronavirus/ COVID-19 for the second time is worrying. If this is a widespread phenomenon and not an isolated case, then it has significant implications for the current pandemic.

Herd immunity, whereby many people are immune to further Coronavirus infection either through previous infection or Vaccination, was suggested as the way of ending the current pandemic.

This report, if confirmed to be true across significant sections of population, would indicate a much more longer duration of COVID-19 pandemic.

Which is better for COVID-19 protection : face masks or face shields.

September 23, 2020September 23, 2020

Various type of masks are used by public for protection against COVID-19.

Some wear cloth masks. Some use medical disposable masks. Some wear face shields particularly those working in shops.

Are they all the same?.

Recent evidence indicates that standard light-blue disposable surgical masks are the most effective at containing the Cornovirus.

Face shields were found to be failing when compared with standard ( triple layer) medical grade masks.

Do soft drinks increase the risk of an early death?

September 14, 2020September 3, 2020

Yes.

Soft drinks do increase risk of an early death.

In a large study involving 451 743 individuals from 10 countries in Europe, the regular consumption of soft drinks increased the risk of death.

The increased risk was seen with both sugared drinks as well as artificially sweetened drinks. Worryingly the hazard from artificially sweetened drinks seems higher.

The take home message: drink more water !

COVID-19 risk assessment of NHS members : is it an opportunity missed?

September 5, 2020September 3, 2020

The National Health Service had recently embarked on a Risk assessment exercise of its staff to assess the Vulnerability of individual members to Coronavirus infection ( COVID-19).

The exercise is being done with good intentions. Given the unprecedented situation of the pandemic and lack of concrete data , the exercise seemed to have steered away from firm “one size fits all” type of recommendations.

Given the uncertainties with the currently available data on various forms of protection ( from simple surgical masks to shielding) , the exercise could have been a starting point for an nationwide intervention study .

An opportunity seems to have been missed and if there is a second wave, NHS might regret not learning from the first wave.

Please do add your opinion at the rapid response section of the BMJ.

Can Coffee cause abortion ?

August 28, 2020November 18, 2020

Yes, it can .

Coffee can harm pregnancy. Coffee can cause miscarriage, stillbirth, lower birth weight, and preterm birth.

Hence various guidelines do advise reduction in coffee consumption during pregnancy.

A recent study in BMJ group journal goes further and suggests avoiding coffee altogether during pregnancy.

There are caveats but those who want to be very cautious should consider avoiding coffee during pregnancy just like one avoids alcohol during pregnancy.

If you survive the Coronavirus, Can you get Coronavirus infection again ?

August 26, 2020August 25, 2020

Yes, you can get infection again.

Last month, we had studies reporting that the immunity to Coronavirus fades quickly after recovering from an infection. The scientists have warned that re-infection is a risk.

Now, we have a case in Hong Kong where a patient seem to have been unlucky to get the infection again. It is a worrying report and suggests that coronavirus is going to be with us for a long time.

The only reassuring fact is that patient was free of symptoms during second infection. One has to hope that all re-infections are mild !

Can you catch Coronavirus infection from Soft drink cans, Sandwich wrapper and Amazon Parcels?

August 24, 2020November 18, 2020

Yes. Possible but chances are very small according to reports.

If someone sneezed or coughed near a parcel or food package and you touch it within a few hours, it is possible to get Coronavirus infection from parcels and packages.

But, in practice, most parcels and food packaging seem safe and no conclusive real world evidence has been published so far to indicate that packages spread infection widely.

In experimental conditions, Coronavirus has been shown to survive for upto 72 hours. The virus is “more stable on plastic and stainless steel than on copper and cardboard”.

In laboratory conditions “On copper, no viable SARS-CoV-2 virus was measured after 4 hours . On cardboard, no viable SARS-CoV-2 virus was measured after 24 hours”.

In the artificial conditions of the lab “The longest viability of viruses was on stainless steel and plastic; the estimated median half-life of SARS-CoV-2 virus was approximately 5.6 hours on stainless steel and 6.8 hours on plastic”.

Solution: If you are worried , and if possible, you can try leaving parcels for 24hrs before touching them with bare hands. Alternatively, try wearing disposable gloves to remove packaging.

Is Honey a better treatment for coughs and colds ?

August 21, 2020August 23, 2020

Possibly yes, in some cases of viral infections , according to a paper published a BMJ group journal ( BMJ Evidence Based Medicine) .

The paper has been widely quoted in various newspapers today.

The BMJ group journal authors report: “Honey was superior to usual care for the improvement of symptoms of upper respiratory tract infections.

It provides a widely available and cheap alternative to antibiotics…….but further high quality, placebo controlled trials are needed.”

A word of caution: Honey has high sugar content. Diabetics need to be careful. People will allergies need to take care. Of course bacterial infections need antibiotics particularly in old and vulnerable!

Is weight loss a sign of cancer?

August 19, 2020August 23, 2020

If you have been dieting and exercising to shed excess weight, then you can celebrate your success in achieving your goal.

But some poorly lose weight unintentionally . This type of weight loss that occurs without intention might be of concern in some people.

A recent article in BMJ advocates screening for cancer in some patients if they have weight loss and other symptoms in their chest and abdomen.

Male smokers over the age of 50 are one of the high risk groups !

Don’t ignore weight loss !

Can you get Coronavirus infection more than once?

July 13, 2020July 12, 2020

If you are one of the unlucky ones to have already been infected with Coronavirus infection but recovered from it, can you become unlucky again and get another Coronavirus infection later this year ?

Unfortunately, the answer is a YES.

Some Viral infections can sometimes lead to life long immunity. For example, most people who had chicken pox as a child tend to have lifelong immunity and it would be uncommon to get chicken pox again. (except in some circumstances).

But infection with ‘Coronavirus causing COVID-19’ doesn’t seem led to long lasting immunity or resistance to a second Coronavirus infection.

A Newspaper report on a study by a team from King’s College London suggests that susceptibility to a second infection may occur as short as 3 months in some patients. This because the level of antibodies produced by the immune system after first infection start to fade away within a few months in some patients.

If confirmed, this is probably one of the most worrying news during this pandemic.

This study result could also affect Vaccine development and how frequently it may need to be administered.

Can Coronavirus linger in air, and cause COVID-19 by spreading through air ?

July 8, 2020November 18, 2020

Normally many flu-like viruses spread by direct or close contact.

Because Virus containing droplets are heavier than air, scientifically it is thought that when someone coughs or sneezes, virus particles quickly fall to ground or surrounding objects.(“like a brick or stone falling to ground“).

But a group of scientists and WHO have raised the possibility that coronavirus can stay in air for longer periods, float around and cause more infections. (“float like a balloon“). This is called air-borne transmission.

What does it mean?

If confirmed– this means “closed spaces” are high risk even if you maintain 2 metre distance from an infected person. AVOID CLOSED SPACES.

As many people in UK do not wear masks in public places, there is a high chance of second wave of infections in the coming weeks as lock down is eased. WEAR A MASK.

It also means avoiding non-essential visitors to hospitals so that visitors cannot catch the infection or pass the infection to vulnerable patients. AVOID NON-ESSENTIAL VISITORS AT HOSPITALS.

If air borne transmission is confirmed, it is also bad news for the coming winter.

If Coronavirus is still in community and not eliminated by winter, air-borne transmission is likely to result in further wave of infections.

This is because Winter means more closed spaces and more chance of infection !!!!!!

STAY SAFE

Can Vitamin D prevent respiratory infections such as COVID-19 ?

July 1, 2020June 30, 2020

No conclusive evidence yet.

Some studies suggest a protective effect but two recent “official” reviews in UK has concluded the following.

(1). “The available evidence does not support vitamin D supplementation to prevent acute respiratory tract infections in the general UK population”.

(2). “There is currently no evidence to support vitamin D supplements reducing the risk or severity of covid-19″.

Can Vitamin K help fight Coronavirus?

June 6, 2020June 10, 2020

Possible but like every other observational study, take it with pinch of salt.

Further evidence from well conducted trials are needed before it can be recommended as a COVID treatment.

In mean time, it’s better to stick to natural sources of vitamin such as those mentioned in the newspaper article ( spinach, broccoli, green vegetables, blueberries, all types of fruit and vegetables).

Does Eating Eggs lead to Heart problems?

June 1, 2020June 6, 2020

No, Eating Eggs in moderation is not associated with increased Heart problems.

Heart diseases are one of major killers in Men and Women. In the past, Cholesterol was exclusively blamed for most of the Heart problems. Nowadays, such a simplistic view has been abandoned. We now know that Heart diseases are due to a complex set of poor diet and life style.

Previously Eggs which have lot of dietary cholesterol have been subject to lot of bad press.

A recent pooled analysis of good quality data shows that ” moderate egg consumption (up to one egg per day) is not associated with cardiovascular disease risk overall, and is associated with potentially lower cardiovascular disease risk in Asian populations.”

So like everything else with regards to diet , moderation is the way to go !

Is Chloroquine useful in treatment of Corona Virus?

May 17, 2020June 10, 2020

Chloroquine and the related drug Hydroxy-Chloroquine are drugs commonly used to prevent and treat Malaria infections; and treat some Joint conditions.

During the initial stages of COVID-19 pandemic, there were some reports of Chloroquine being useful in treating Corona Virus.

A Chinese trial published in British Medical Journal BMJ now reports that ” Administration of hydroxychloroquine did not result in …. any meaningful antiviral benefits… compared to standard of care alone in patients admitted to hospital with mainly persistent mild to moderate covid-19”

Chloroquine was not only useless but it had significant side effects in a minority. So Chloroquine or Hydroxy-Chloroquine should not be used routinely outside a clinical trial setting.

Face Masks: Should Public wear face masks because of Corona Virus pandemic ?

May 17, 2020November 18, 2020

Should Public wear face masks because of Corona Virus pandemic ?

Yes.

In some of the Asian Countries there has been universal acceptance of face masks even before Corona Virus pandemic. Hence, it is not surprising that there is wide spread use of face masks during this pandemic .

In USA, after initial hesitation, CDC now recommends use of cloth face masks by public.

In Germany, many states have made face masks compulsory.

In UK, there has been no official recommendation about widespread use of face masks.

With so many unknowns, it is prudent to follow the advice published in British Medical Journal : WEAR A MASK !!

Does air pollution in cities make your jogging and walking less beneficial ?

May 4, 2020January 22, 2020

Yes, air pollution is now being recognised as an important cause of death in major cities and towns.

So avoid major roads and very busy streets.

Any benefit you might accrue from exercise can be wiped out by heavy air pollution if you are jogging on a heavily congested road.

Plain English Medical Letters to Patients

March 11, 2020November 18, 2020

Writing letters to patients in plain English without medical jargon is a gift that only a few doctors possess.

Personalising complex medical terminology in a letter dictated over a few minutes is NOT an inherent skill possessed by many doctors including those who are native English speakers.

Dictating Plain English medical letters would take considerable time and effort – particularly if letters are going to succinctly summarise everything from a medical consultation.

In UK, with regards to Cancer, we are lucky to have cancer charities who do a good job of providing information in plain English ( E.g Cancer Research UK, Macmillan Cancer Support, Prostate Cancer UK).

Cancer Patients in UK also have the support of Cancer Nurse Specialists ( CNS ) who do a fantastic job of guiding patients through their cancer journey and clarify all medical jargon to patients.

Other specialities might not have the resources that are available to cancer patients. But, on the whole, Clinic Time slots are precious. Many UK specialists have long waiting lists.

So if further time and effort is to be expended in busy clinics for dictating plain English Letters – in addition to the usual Medical letters to GP – good clinical evidence is needed to demonstrate that separate plain English letters do benefit patients in a meaningful way.

Please do read the BMJ article and put forward your views in the rapid response section.

Do omega 3 supplements provide protection from Stroke and Heart diseases?

February 3, 2020July 18, 2019

It is a common belief that omega 3 fatty acids provide protection from strokes and heart attacks, and improve overall health.

A review from the esteemed Cochrane collaboration pours cold water on this belief.

The review concludes that omega 3 provides ” little or no meaningful effect on the risk of death from any cause”.

They conclude that “omega 3 supplements probably makes little or no difference to risk of cardiovascular events, coronary heart deaths, coronary heart disease events, stroke or heart irregularities”.

The review did find “moderate evidence that ALA, found in plant oils (such as rapeseed or canola oil) and nuts (particularly walnuts) may be slightly protective of some diseases of the heart and circulation”.

However, the effect was very small. They estimated that “143 people would need to increase their ALA intake to prevent one person developing arrhythmia”.

They also estimated that “One thousand people would need to increase their ALA intake to prevent one person dying of coronary heart disease or experiencing a cardiovascular event”.

Overall the review finds that overall “omega 3 provides little if any benefit at all”.

Walking is good exercise

January 23, 2020January 22, 2020

New year. January. First month of a New year – it’s the time of year many people take a look at their lifestyle and vow to eat better, exercise better and live better.

Many people consider Gym or Health Club membership.

But Exercise doesn’t need to cost a lot. Being active, doesn’t need to be regimented.

Simply walking anywhere is good compared to no exercise at all. Walking in the Park or Quiet streets has lot of benefits.

Good article in BBC on the benefits of walking.

A word of caution though !

Avoid Walking or Jogging near busy roads so that the benefits of walking are not negated by pollution.

Is whole milk harmful ?

December 6, 2019December 5, 2019

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”.

Futile antibiotic treatments

December 3, 2019December 5, 2019

Infections are normally highly treatable with antibiotics.

But when someone is dying , the body’s immune system gets weaker. Hence infections quite often occur as part of the dying process.

Treating these infections are often futile. But human nature is inclined to “fight and survive” by all means. So quite often powerful antibiotics are used to treat these infections in dying patients.

There is an ethical argument against futile treatments.

There is also the risk of antibiotic resistance in general population if antibiotics are used inappropriately.

Yes, it can.

It has been well established by systemic review that working long hours can lead to excessive heart attacks. ( ref 1).

The study reports that “Damp and windy days with low pressure can increase risk of experiencing more pain than normal”

“Cold, damp days also made pain worse but interestingly pain was not made by temperature alone”.

Other studies in the past have also found a “significant correlation between humidity and pain“.

Researchers have adjusted the data for confounding factors. Evidence so far is very intriguing.

And the next question is – can one learn to be optimistic, change personality and have beneficial health effects. We don’t know at present.

Dietary advice: take it with a pinch of salt

October 1, 2019October 1, 2019

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 Vegan diet the most healthy ? Are there any risks from Vegetarian diet?

September 5, 2019September 5, 2019

Life would be very simple if we can have clear cut answers with regards to the best diet for everyone’s health.

A recent study published in BMJ indicates that while Vegan diet reduces risk of heart problems it can increase the risk of strokes.

The results might seem confusing and scientists would be certainly seeking more answers. But don’t be surprised if another study from some other research group comes up with a contradictory result. That’s normal in science.

What’s most important is to realise that there are no easy scientific answers to most scientific questions. Research quite often shows unexpected results. What is a logical scientific question quite often throws up unexpected answers.

Overall, the message is “have a well balanced diet” without omitting essential nutrients.

Surprising Number of Americans Believe Alternative Therapies Can Cure Cancer

February 15, 2019January 26, 2019

Photo by rawpixel.com on Pexels.com

A recent National Cancer Opinion Survey found that a significant Number of Americans Believe Alternative Therapies Can Cure Cancer.

Nearly four in 10 Americans (39%) believe cancer can be cured solely through alternative therapies such as enzyme and oxygen therapy, diet, vitamins, and minerals.

Even many of the respondents with direct cancer experience—people who have or had cancer and family caregivers—believe cancer can be cured solely through alternative medicine.(22% and 38%, respectively).

The American survey also found that younger people are the group most likely to hold these views: 47% of people ages 18 to 37 and 44% of people ages 38 to 53.

It is counterintuitive that the generation with access to vast online information at the swipe of a finger holds such unscientific views. One wonders whether the social media is inadvertently promoting misinformation.

Can Turmeric control cancer ?

February 1, 2019January 26, 2019

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.
