വെളിച്ചെണ്ണ ശുദ്ധ വിഷമാണെന്നു ഹാര്‍വാര്‍ഡ് പ്രഫസര്‍
ബോസ്റ്റന്‍: വെളിച്ചെണ്ണ ശുദ്ധ വിഷമാണെന്നും ഇത് ഉപയോഗിക്കുന്നതു പോലെ ദോഷകരമായി മറ്റൊന്നുമില്ലെന്നും ഹാര്‍വാര്‍ഡ് സ്‌കൂള്‍ ഓഫ് പബ്ലിക്ക് ഹെല്ത്തില്‍ എപ്പിഡെമിയോളജിസ്റ്റ് പ്രഫസര്‍ കാരിന്‍ മിഷല്‍സ്. ജര്‍മ്മന്‍ സര്‍വകലാശാലയില്‍ അവര്‍ ചെയ്ത പ്രസംഗത്തിന്റെ യൂട്യൂബ് ലിങ്ക്ഒരു ദശലക്ഷം ആളുകള്‍ കണ്ടു കഴിഞ്ഞു.

കൊഴുപ്പിന്റെ അളവ് കൂടുതലാണെന്നും ഇത് ഉയര്‍ന്ന കൊളസ്ട്രോള്‍ നിരക്കിനും അതുവഴി ഹൃദയാഘാതത്തിനും കാരണമാകുമെന്നാണ് മിഷല്‍സ് പറയുന്നത്. മുന്നറിയിപ്പു നല്‍കാന്‍ മാത്രമേ തനിക്കു കഴിയുകയുള്ളൂവെന്നും 'വെളിച്ചെണ്ണയും മറ്റു പോഷക ന്യുനതകളും' എന്ന തലക്കെട്ടുള്ള പ്രസംഗത്തില്‍ പറയുന്നു.

വെളിച്ചെണ്ണ പല രോഗത്തിനും സിദ്ധൗഷധമാണെന്ന രീതിയില്‍ ചില കമ്പനികള്‍ പ്രൊമോട്ട് ചെയ്യുന്നതിനെ അവര്‍ ചോദ്യം ചെയ്യുന്നു. വെളിച്ചെണ്ണയില്‍ 80 ശതമാനം കൊഴുപ്പാണു്. മ്രുഗ കൊഴുപ്പിലുള്ളതിനേക്കാള്‍ 60 ശതമാനം കൂടുതലുണ്ട് ഇത്.

എന്നാല്‍ ഹാര്‍വാര്‍ഡ് സ്‌കൂള്‍ ഓഫ് പബ്ലിക് ഹെല്‍ത്തിലെ തന്നെ ഡോക്ടറായ വാള്‍ട്ടര്‍ സി. വില്ലറ്റ് പറയുന്നത് വെളിച്ചെണ്ണ അത്ര അപകടകാരിയല്ലെന്നാണ്. വല്ലപ്പോഴും ഉപയൊഗിക്കാം.

എന്നാല്‍ വെളിച്ചെണ്ണ ദോഷകരമാണെന്ന നിലപാടിലാണു നല്ലൊരു പങ്ക് നൂട്രിഷനിസ്റ്റുകളും.

For certain health food shops and wellbeing sites it is the panacea that helps everything from bad hair and mental grogginess to obesity and haemorrhoids. But the carefully-crafted image of coconut oil as a cure for many ills has been roundly rejected by a Harvard professor.

Karin Michels, an epidemiologist at the Harvard TH Chan school of public health, poured scorn on the superfood movement and singled out the fad for coconut oil in particular, calling the substance “one of the worst things you can eat” that was as good for wellbeing as “pure poison”.

Michels made her comments in a recent lecture entitled “Coconut oil and other nutritional errors” at the University of Freiburg, where she holds a second academic position as director of the Institute for Prevention and Tumour Epidemiology. The speech, delivered in German, has now been watched nearly a million times on YouTube.

Michels based her warning on the high proportion of saturated fat in coconut oil, which is known to raise levels of so-called LDL cholesterol, and so the risk of cardiovascular disease. Coconut oil contains more than 80% saturated fat, more than twice the amount found in lard, and 60% more than is found in beef dripping.

Last year, the American Heart Association reviewed the evidence on coconut oil among other foodstuffs. While three quarters of the US public considered coconut oil to be healthy, the review noted that only 37% of nutritionists agreed. The authors attributed the gulf in perception to the marketing of coconut oil in the popular press. “Because coconut oil increases LDL cholesterol, a cause of CVD, and has no known offsetting favourable effects, we advise against the use of coconut oil,” the review concluded.

Other organisations have issued similar warnings. “Coconut oil can be included in the diet, but as it is high in saturated fats should only be included in small amounts and as part of a healthy balanced diet,” the British Nutrition Foundation said. “There is to date no strong scientific evidence to support health benefits from eating coconut oil.”

Despite the advice, promotions from health food shops such as Holland and Barrett, and celebrity endorsements from Gwyneth Paltrow and others, have helped UK sales of coconut oil surge in recent years from about £1m to £16.4m in the past four years, according to the consumer research group Kantar. In the US, coconut oil sales appear to have peaked in 2015 at $229m, according the market research firm Spins.

“Coconut oil is about 86% saturated fat, about one-third more saturated fat than butter,” said Victoria Taylor, a senior dietician at the British Heart Foundation.

“We know that diets high in saturated fat are associated with increased non-HDL cholesterol in the blood, and high cholesterol is a risk factor for coronary heart disease and stroke.

“There has been speculation that some of the saturated fat present in coconut oil may be better for us than other saturated fats, but so far there is not enough good-quality research to provide us with a definitive answer.

“What we do know is that replacing saturated fats with unsaturated fats like vegetable oil, olive oil and sunflower oil, and their spreads, has been shown as an effective way to help reduce LDL cholesterol levels, so this would be a healthier choice.

“For the time being, if you like the taste of coconut oil, then, as with butter, it’s fine to use it every now and then. However, it’s best to restrict yourself to small amounts and use unsaturated oils as an everyday choice instead.”

Coconut oil is historically used in Kerala (India) for treating a number of ailments. It is an essential ingredient in may aurvedic medicines. It is used as a lubricant, aftershave, antifungal, antibacterial, antiseptic, antiviral and also as moisturizer. Quite a number of skin care and hair care products' base is coconut oil. Recently it was indicated that it is good for the treatment of dementia....

"Does coconut oil help people who have Alzheimer's disease?"

It's a question that, as it turns out, is surprisingly difficult to answer.

Could it help?

"Absolutely it could," says Carolyn Dean, M.D., N.D., medical director for the Nutritional Magnesium Association.

According to Dean, the potential health benefits of coconut oil have been celebrated since ancient times by different cultures around the world. It's been used as an anti-fungal treatment, a hair-strengthener and a skin softener.

Coconut oil, classified as a medium-chain triglyceride, may even be beneficial for people suffering from other incurable diseases, such as Parkinson's, Multiple Sclerosis and ALS (Lou Gehrig's disease).

Dean witnessed the potential curative power of coconut oil while working with individuals suffering from HIV and AIDS. "We started getting stories about people with HIV that took coconut oil and felt better. As the testimonials started growing, all of us began to realize that there must be something to it."

But, to understand how coconut oil could help someone with Alzheimer's disease, one must first examine the connection that exists between blood sugar, the human brain and diabetes.
