Link between drinks and obesity

2012-09-23 14:32

Washington -Three new studies published in the United States this weekend reaffirm a link between sweet soda and fruit drinks to an epidemic of obesity that is sweeping the United States.

Consumption of these drinks has more than doubled since the 1970s, and the rate of obesity among Americans during the same period reached 30% of the adult population, said the authors of a study published online by the New England Journal of Medicine.

The first study, which involved more than 33 000 American men and women, showed that drinking sugary drinks was affecting genes that regulate weight and increased the genetic predisposition of a person to gain weight.

The researchers used 32 variations of genes known to affect the weight to establish a genetic profile of the participants. They also determined the participants' eating habits, their consumption of sweetened beverages and exercise practices.

The other two studies showed that giving to children and adolescents calorie-free drinks like mineral water or soft drinks sweetened with artificial sweeteners resulted in weight loss.

The first was conducted at Children's Hospital Boston, which examined 224 overweight adolescents who were encouraged to consume water or light sodas for a year.

Sugary drinks

These teens gained only 0.68kg of weight during this period compared to 1.5kg in another group that consumed sugary drinks.

Yet another study was conducted by researchers at the VU University Amsterdam (the Netherlands) and involved 641 children aged 4 to 11.

Half of the group drank sweet and fruity drinks while the other half the same drinks with sugarless sweeteners.

After 18 months, children who consumed the low-calorie drinks gained 6.39kg on average compared to 7.36kg in the group that drank sugary fruit drinks.

"Taken together, these three studies suggest that calories from sugar-sweetened beverages do matter," said Doctor Sonia Caprio of Yale University writing in the New England Journal of Medicine.

"These randomised, controlled studies ... provide a strong impetus to develop recommendations and policy decisions to limit consumption of sugar-sweetened beverages, especially those served at low cost and in excessive portions, to attempt to reverse the increase in childhood obesity," she added.

      You should at least watch this before you dismiss the sugar issue. http://www.uctv.tv/skinny-on-obesity

      Why does it take years of study to prove a given? Totall calories consumed - total calories used = weight gain/loss. If you drink sugary stuff, beer, whatever and combined with your food intake the calories exceed the calories you use you WILL gain weight. Fruit juice is "healthy" but fattening. There is a huge con going on. People read "healthy" but don't read how calorie laden some stuff is. Nuts are healthy but extremely fattening, etc...

    We are addicted to carbs, which are so easy to mass supply. The Paleo-diet consisted of proteins, fats, and rough greens, and our pancreas and insulin response is completely buggered with our modern day dependence on starches(especially refined ones).

    all a load of hogwash - I have two gardeners.(Yes, it's expensive and I really don't 'need' them). One is 93 - and yes, we've offered him a substantial pension (besides the one he gets from his formal employment which terminated at 65) and begged him to stay at home but he ignores/scorns us (says he'd rather work than die lazy) and turns up and gets stuck in to work until we give him his cooked breakfast, lunch and two teas - consisting of plates piled high with carbs and fatty proteins(his foods of choice) accompanied by huge mugs of tea sweetened with 6 spoons of sugar each time. I kid you not. (He drinks 5 of these each day he works - and he works 6 days a week). The other chap who is much younger at 57 (we employ him because his employer died and we thought he'd relieve the old man of some labour (ha ha!!) has the same. Both are lean and trim, full of energy with the bodies of much younger men. PHYSICAL EXERCISE and WORK. Humans evolved to run (hunters) and walk (gatherers). We are going against our nature slobbing in seats and gobbling without gathering. Only those who can afford to eat and do no physical labour and hard exercise are obese....Read Prof Tim Noakes "Challenging Beliefs". All the men in my family are insomniacs. Restless energy with not enough physical activity to burn it...they don't sleep. Son lets sit up even later and work on computers and watch television. Urghhhhhhhhhhhhhhh. Makes for very unhealthy living.
