Many advocates of the so-called Paleo diet will tell you that our ancestors’ plates were heavy on meat and low on carbohydrates — and that, as a result, we have evolved to thrive on this type of nutritional regimen.

Herman Pontzer, an evolutionary anthropologist at Duke University and author of  Burn , a book about the science of metabolism, says it’s a myth that everyone of this time subsisted on meat-heavy diets. Studies show that rather than a single diet, prehistoric people’s eating habits were remarkably variable and were influenced by a number of factors, such as climate, location and season. I

  By Matt Lloyd,  - BBC News, Edited by -  Amal Udawatta,                         The beast is believed to be the biggest fish ever caught in Welsh waters   A giant 900lb (408kg) tuna believed to be the biggest fish ever caught in Welsh waters has been landed by an angler, fittingly named Batey. Simon Batey and friend Jason Nott caught the Atlantic bluefin tuna off the Pembrokeshire coast. The huge 9ft (2.82m) fish was caught, measured and then released. Campaigners said Welsh waters now boast some of the biggest fish in the world and want a fishery established to attract international anglers. Mr Batey, from Sarn, Bridgend, landed the tuna while returning from fishing in an area of the Irish Sea known as the Celtic Deeps, approximately 30 miles off the west Wales coast. During the hour-long struggle, he passed the rod to Mr Nott, from Cwmaman, Rhondda Cynon Taf, while working with skipper Andrew Alsop. It was measured from the nose to the fork of the tail while a globally recognised f

 From - Knowable Magazine, By  Bob Holmes , Edited by - Amal Udawatta, Vegetarianism and veganism aren’t the only options for diners who are concerned about environmental sustainability. Diets with a small amount of meat can actually have a smaller environmental footprint — in the long run, at least. CREDIT: PETER AND MARIA HOEY Scientists find that a small amount of animal products could have a place in our diets without wreaking environmental havoc. But it’s far less than what we consume today, and only if farmed in just the right way. As governments drag their feet in responding to climate change, many concerned people are looking for actions they can take as individuals — and  eating less meat  is an obvious place to start. Livestock today account for about 14.5 percent of global greenhouse gas emissions, mo than all the world’s cars and trucks combined. Those numbers are daunting already, but the situation could grow worse: Our appetite for meat is increasing. The United Nations f

Studies of the Hadza diet reveal that they eat a seasonally changing variety of meat, fruit, tubers and honey — a far cry from today’s meat-heavy “Paleo diet.”       CREDIT: © MATTHIEU PALEY hat did people eat for dinner tens of thousands of years ago?
