A “freedom food” turkey which has had a free range life on it’s natural diet – how does it differ nutritionally from intensively reared birds?<\/figcaption><\/figure>\n

The first of a series of talks on the first Monday of each month at 7pm (after running club). All runners\/massage and PT clients are very welcome to attend. The talks are free and will address various aspects of nutrition and training and should appeal to a wide audience. They are informal and friendly.
\nOn Monday 7th August the title of the talk is “Dietary Fat – Friend or Foe”. Over the last 40-50 years the government advice has been to encourage a low fat calorie controlled diet yet the incidence of obesity and Type 2 diabetes is higher than ever. Are we lazy gluttons? Or is the advice seriously flawed? This talk looks at the types of fat present in food, the evidence for and against eating fats on health grounds and the role of the food industry in adding fats to processed foods.\u00a0The aim is to present more information on dietary fat than is generally available, based on scientific studies from the reading list, to assist individuals in making their own personal dietary choices.<\/p>\n

      Some points to ponder:<\/strong><\/p>\n

      In 1984, the US National Heart, Lung and Blood Institute launched a massive health campaign. They undertook a decade long trial to test the idea that eating less saturated fat would curb heart disease. Not a single heart attack was prevented. After 10 years and $115m they gave up.<\/p>\n

      In the early 1990s, the National Institute of Health instigated the Women\u2019s Health Initiative costing around a billion dollars. Amongst the questions asked was whether a low fat diet prevented heart disease or cancer. Fifty thousand women were divided into two groups, a low fat group and an \u201ceat what you like\u201d group. After six years, the \u201clow fat\u201d group had cut both their saturated fat and total fat consumption by a quarter, slightly lowered their total and LDL cholesterol to just below that of the \u201ceat what you like\u201d group, and had lost only 2lbs. There was no difference in their incidence of heart disease, stroke, breast cancer or colon cancer. In fact, there was no observable benefit at all of a low fat diet.<\/p>\n

      In 2007, Stanford University conducted an \u201cA TO Z Weight Loss Study\u201d.\u00a0 Subjects were instructed to eat as much fat and protein as they wanted but avoid carbohydrates i.e a high fat, high saturated fat diet. They were compared with those on a low fat, low saturated fat restricted calorie diet. Those who ate mostly fat and protein<\/p>\n
