Why more vegetarians don't become vegans

The Labour leader has been a vegetarian for almost 50 years after working on a pig farm when he was in his early 20s.

Speaking to staff at an outlet of cosmetics retailer Lush, the 68-year-old said: "I eat more and more vegan food and have more and more vegan friends.

"There are quite a lot of vegan MPs - not a lot but there are some.

"One of my close relatives has just become a vegan and I went to her house for dinner and it was absolutely brilliant.

Bodybuilder dies after eating high-protein diet

Days later, Hefford was pronounced dead. Only after her death did her family learn that Hefford, the mother of a 7-year-old girl and a 5-year-old boy, had a rare genetic disorder that prevented her body from properly metabolizing her high-protein diet.

World's most obese nation

recent study found that more than 2 billion adults and children globally are overweight or obese and suffer health problems because of that -- but this is nothing new.

What a hunter-gatherer diet does to the body

Diet is key to maintaining diversity and was strikingly demonstrated when an undergrad student went on a McDonald's diet for ten days and after just four days experienced a significant drop in the number of beneficial microbes.

Similar results have been demonstrated in a number of larger human and animal studies.

Coconut oil 'as unhealthy as beef fat and butter'

It is packed with saturated fat which can raise "bad" cholesterol, says the American Heart Association in updated advice.

Coconut oil is commonly sold as a health food and some claim the fat in it may be better for us than other saturated fats.

The AHA, however, says there are no good studies to support this.

'Seductive names' make vegetables more appealing

A team at Stanford tried it out on students in the university cafeteria and found veggie sales went up by 25% when indulgent labels were used.

"Sizzlin' beans", "dynamite beets" and "twisted citrus-glazed carrots" tempted diners to fill their plates.

Healthy labels, such as "wholesome", were a turn-off, even though the dishes were identical in every other way.

Seductive carrot... 

The experiment took place over the whole of the autumn academic term. Each day, a vegetable dish was labelled up in one of four ways:

Weight-related deaths can affect non-obese too

Of the 4 million deaths attributed to being overweight in 2015, nearly 40% were not considered clinically obese.

The study found more than 2 billion children and adults suffered from health problems linked to being overweight.

These include type 2 diabetes, heart disease and some cancers.

But an increasing percentage had a body mass index (BMI) of less than 30, the threshold for obesity.

The secret behind healthy Greek hearts

They found a new genetic variant, common among villagers, which appears to protect the heart by lowering levels of "bad" fats and cholesterol.

Despite a diet rich in animal fat, the people of Mylopotamos in northern Crete do not suffer from cardiovascular disease.

And they really love their cheese.

What's special about these Greek villages?

The isolated villages of Zoniana and Anogia are high up in the mountains on the island of Crete.

Few people move in or out of the villages and the inhabitants are known for living well into old age.

Weight loss can be tied to when, not just what, you eat

You might skip breakfast. At lunch, you may opt for a salad with lots of veggies, no croutons and low-fat dressing -- on the side, of course.

Then, three o'clock hits.

You're incredibly hungry and craving candy, sweets or chips. You finally cave, eating a candy bar or other treat.

By 6 p.m., you're tearing the kitchen apart, snacking on anything you see.

Mauritius: The island where food is everywhere

It's a globe-spanning display of produce that migrated here along the paths of the sailing ships that brought settlers, slaves and servants to Mauritius.

"It's a melting pot, curry from India, noodles from China," says Linzy Bacbotte, a Mauritian singer and advocate of Creole culture. "It's very colorful, all the spices. And if you want a snack, the dried fish. It's yum."

She also likes a drink called alouda, sort of a milkshake with tapioca balls and sweetened with flavored syrups.

But Mauritius is one of those places where a bounty of snacks are never far away.
