Egg yolk nutritious,  rich in vitamins

Do you always toss out the yolks when you make an omelette? If studies are to be believed, avoiding egg yolks could mean you are missing out on good nutrition. Whole eggs don't raise your risk of heart disease - in fact, according to nutrition coach Liz Wolfe, it may be worse for your health to not eat them.

In 2010, The American Journal of Clinical Nutrition published a meta-analysis which stated that “saturated fat was not associated with an increased risk of coronary heart disease, stroke or coronary vascular disease.” Earlier this year, Time magazine, too, reversed the argument it made in a 1984 cover story claiming eggs and other high-fat foods were dangerous.

Wolfe suggests that the real cause of heart disease lies in the inflammation caused by “chronic stress levels, and the overconsumption of vegetable oils and processed carbohydrates.”

According to Wolfe, egg yolks are “a great source of vitamin A, which is good for skin, B vitamins for energy and choline, which supports brain health, muscles and is necessary for a healthy pregnancy.” The saturated fat in yolks is also necessary for hormone production and the body's absorption of vitamins and minerals.

Effect of altered epigenome on Alzheimer's revealed

A study by Brigham and Women's Hospital (BWH) and Rush University Medical Center, has revealed how early changes in brain DNA methylation are involved in Alzheimer's disease.

DNA methylation is a biochemical alteration of the building blocks of DNA and is one of the markers that indicate whether the DNA is open and biologically active in a given region of the human genome. According to the study, the approach may help them to better understand the biological impact of environmental risk factors and life experiences on Alzheimer's disease.

Lead study researcher Philip L. De Jager from BWH Departments of Neurology and Psychiatry said that there are certain advantages to studying the epigenome, or the chemical changes that occur in DNA.

The epigenome is malleable and may harbor traces of life events that influence disease susceptibility, such as smoking, depression and menopause, which may influence susceptibility to Alzheimer's and other diseases.

The findings revealed that methylation levels correlated with Alzheimer's disease in 71 of 415,848 CpG markers analyzed. These 71 markers were found in the ANK1 and RHBDF2 genes, as well as ABCA7 and BIN1 which harbor known Alzheimer's disease susceptibility variants.

Vinegar in diet cleanses system, aids digestion


Sipping on a vinegar-infused drink every morning is the latest health food item endorsed by celebrities to lose weight.

Actress Megan Fox has said that because of her “really big sweet tooth”, she'll sometimes cleanse with a combination of apple cider vinegar and water, claiming it “cleans out your system”.

Supermodel Miranda Kerr drizzles it on her salad, while actress Gwyneth Paltrow and singer Madonna rely on it to keep their looks in check.

Now there is also a restaurant, The Raw Duck in London's Hackney, an eatery to have a menu dedicated to ferments, and apple cider vinegar with a little sugar and grated apple left to develop for three days is one of its most popular items.

“These are deliciously cleansing and help aid digestion,” owner Rory McCoy said. “When we talk about probiotic, we think of those mass-produced yoghurts but these are the real thing. People should know about them. I try to drink a vinegar or eat a ferment every day for my health,” added McCoy.


Katy Mason, nutritionist at The Nutri Centre, says vinegar has been used for centuries for many purposes, like pickling, cleaning as a condiment and for health. “If you look on the internet you will find claims that vinegar, especially apple cider vinegar, will relieve just about any ailment you can think of,” she said.

“Nutritional therapists have known about this product for years and will often recommend it to clients to help stimulate the digestion, alkalise the body and help with weight loss,” she added.
