Food industry dooms children to obesity, says scientist Related Product Information Carbohydrates and fibres (sugar, starches) Fats & oils Related Product Newsletters Carbohydrates and fibres (sugar, starches) Fats & oils News Archives All news for January 2007 All news for December 2006 29/01/2007 - Higher intake of fats is associated with lower body weight, says new research from Sweden that offers an alternative side to the role of fat intake in the rise of obesity. The research also correlated higher BMI with higher sugar intake. Researcher Malin Haglund Garemo, a dietician from Gothenburg University in Sweden, said that more studies are planned to investigate if obesity was being caused by an early increase in insulin, and not fat. "Such results would go against the common perception that fat causes increased insulin production as a result of insulin resistance," she said. The rate of childhood obesity is set to double by the end of the decade, according to recent forecasts by the International Obesity Task Force (IOTF). The alarming figures on childhood obesity estimate that by 2010 almost 287 million kids will be obese, and the overall obese population could rise to 700 million by 2015. Garemos dissertation study focussed on 182 healthy four-year-olds in Gothenburg and examined eating habits and lifestyles. Twenty per cent of the children were classified as being overweight based on their body mass index (BMI greater than 25 kg per sq. m and less than 30 kg sq. m), and two per cent were obese (BMI greater than 3030 kg sq. m). "Most of the children in our study come from good socioeconomic backgrounds. If the study had reflected all four-year-olds in Sweden, more children would probably have been overweight," said Haglund Garemo. Diets, socio-economic, lifestyle and health questionnaires were completed by the parents of the children, and analysis of the children's body build showed that weight increases was a result of the body storing more fat, but those who ate the most fat were not the ones who weighed most. Instead, children who ate less fat had higher BMIs, reports Haglund Garemo. Startlingly, a fourth of all energy requirements of the children was coming from "junk food" (candy, ice cream, cookies, and sweet beverages), despite the overall energy intakes being in accordance with Nordic nutrition recommendations (NNR 2004). "Most children had higher intake of saturated fat and sucrose than NNR 2004, while the intake of polyunsaturated fat - especially omega-3 fatty acids, vitamin D and iron were lower than recommended in most children," wrote Haglund Garemo. "Every third child in the study ate far too little unsaturated fat, above all too little omega-3. These children had significantly higher body weight. This supports other studies that show that obese children have shortages of omega-3," she said. Haglund Garemo also reported that many of the four-year old girls in the study were already displaying signs of the metabolic syndrome, a condition characterised by central obesity, hypertension, and disturbed glucose and insulin metabolism. The syndrome has been linked to increased risks of both type 2 diabetes and CVD. Indeed, the research indicated that children with the highest insulin levels gained the most weight since birth. "Risk factors for the metabolic syndrome can be identified already in healthy 4-year olds, especially in girls," she said. The Swedish Research Council published the research findings. *** The "Swedish Paradox"? TC Here are the vital factors found in the research, it is the now familiar good vs. bad fat observation. Polyunsaturated fats from fish and plant sources not amount of fat is the key point. The subject line is misleading, pure spin to be frank.

Do you have a problem with the concept that not all fats are bad and not all animal fats are bad? And do you have a problem wuth the idea that animal sourced foods are actually healthy? Or do you hold the same ideas as Ancel Keyes? Where exactly do YOU sit on the animal fats debate?

Yes, but far less omega3 sourced fish and plant fats, which was the finding of the article. Olive oil has the most monounsaturated fat and has other health things going for it also. "Do you have a problem with the concept that not all fats are bad and not all animal fats are bad? And do you have a problem wuth the idea that animal sourced foods are actually healthy? Or do you hold the same ideas as Ancel Keyes?" No problem at all, I agree with keyes that grape nuts is a tasty cerial. Moderation is always the best approach for all things unless such as in diabetes one must limit some foods, both carbs and saturated fats in my view based on research. Some research suggests that diabetes is as much a disorder of fat metabolisim and that saturated fats have a higher risk attached. "Where exactly do YOU sit on the animal fats debate?" As above. :: "Polyunsat fat is found in pork, chicken and other meats too." :: [quoted text clipped - 17 lines] :: :: As above. I find it hard to believe that diabetes is a disorder of fat metaboliusm and that sat fats relate to a higher risk in the absence of carbs. Thus, I'm dubious of such research. "I find it hard to believe that diabetes is a disorder of fat metaboliusm and that sat fats relate to a higher risk in the absence of carbs. Thus, I'm dubious of such research." The research is related to what risk factors are associated with metabolic disorder and diabetes. The fat link comes in with what happens to beta cells and other cells related to level of insulin resistance. Obviously it is then that glucose metabolism enters the picture. As in most things biological there is no one straight line set of actions but an interaction and feedback of variables that occurs. Both fat and glucose are involved and act upon the actions of each other. Here is one example abstract illustrating this: [_] 1: Med Sci Monit. 2006 Dec 18;13(1):RA12-17 [Epub ahead of print] High fat diet modulation of glucose sensing in the beta-cell. Type 2 diabetes is primarily associated with beta-cell failure, insulin resistance and elevated hepatic glucose production. The islet beta-cell is specialized for the synthesis, storage and secretion of insulin. Beta-cell failure is characterized by the inability of the beta-cell to secrete sufficient insulin in response to glucose, which ultimately results in hyperglycemia- the clinical hallmark of Type 2 diabetes. Impairment in glucose sensing contributes to beta-cell dysfunction. The facilitative glucose transporter, GLUT-2, and glucose phosphorylating enzyme, glucokinase, are key for glucose sensing of the pancreatic beta-cell, the initial event in the pathway for glucose-stimulated insulin secretion. There is an increase in dietary fat intake, particularly saturated fat, in both the developing and Westernized world, which predisposes individuals to become obese and to potentially develop insulin resistance, beta-cell dysfunction and Type 2 diabetes. A high fat diet is known to reduce both GLUT-2 and glucokinase expression thereby impairing glucose-stimulated insulin secretion. Furthermore, a high fat diet and specific free fatty acids, induces oxidative stress and apoptosis which reduces beta-cell mass and compromises beta-cell function. Glucose sensing is the initial event of glucose-stimulated insulin secretion therefore it is imperative to maintain adequate expression levels of GLUT-2 and GK for ensuring normal beta-cell function. The development of pharmaceutical agents that improve glucose-stimulated insulin secretion may replenish expression of these glucose sensing genes after their attenuation by high fat feeding.

Instead of their conclusion being that not enough "good fats" is bad, why couldn't it be that too much sugar is bad? Why not attack the sugar content of the diet instead of the fat content? It couldn't be that attacking sugar content means nothing while attacking fat content means more dollars for research?

Instead, children who ate less fat had higher BMIs, reports Haglund Garemo" The above is the central fact that stands conventional wisdom on it's head. You can further refine it, and say healthy fats are better than others, which few would argue with. However, that isn't going to do much good, when the accepted wisdom is still that dietary fat is what causes obesity and the answer is more low fat food. :: On Jan 30, 9:17 am, "Bob in CT" <ctvigge...@adelphia.net> wrote: ::: [quoted text clipped - 43 lines] :: dietary fat is what causes obesity and the answer is more low fat :: food.
