Obesity is now not only more common, but also affecting kids more often. It’s linked to all other problems of metabolic syndrome. In recent years, evidence has been mounting to link the consumption of sugar and sweetened foods with increasing prevalence of obesity, across the ages. Although several therapeutic approaches are being tried, including surgical interventions, the root cause of the obesity epidemic being the modern diet, the most important, most effective, most healthy and least invasive intervention is dietary intervention itself.

Sugar is Toxic: The growing scientific evidence, both epidemiological and mechanistic, very clearly shows that excess sugar induces all of the diseases associated with the metabolic syndrome, Robert H. Lustig et al write in Nature. See Lustig RH, Schmidt LA, Brindis CD. Public health: The toxic truth about sugar.

Modern day food causes all the ills: The highly processed, calorie-dense, nutrient-depleted diet frequently leads to exaggerated supraphysiological post-prandial spikes in blood glucose and lipids. This post-prandial dysmetabolism induces immediate oxidant stress, which increases in direct proportion to the increases in glucose and triglycerides after a meal. The transient increase in free radicals acutely triggers atherogenic changes including inflammation, endothelial dysfunction, hypercoagulability, and sympathetic hyperactivity. To attenuate the increase in glucose, triglycerides, and inflammation after a meal,  a diet rich in minimally processed, high-fiber, plant-based foods, including vegetables and fruits, whole grains, legumes, and nuts is recommended. Other dietary interventions that can significantly ameliorate postprandial dysmetabolism include intake of lean protein, vinegar, fish oil, tea, and cinnamon. Additional benefits may result from calorie restriction, weight loss and exercise.See O’Keefe JH, Gheewala NM, O’Keefe JO.

Dietary fructose linked to metabolic syndrome and diabetes mellitus: In a new study from Vanderbilt University in Nashville, Tennessee, a diet with 30 percent of total energy from fructose was given to 29 adult male rhesus monkeys aged 12 to 20 years for a period of 12 months. Starting at six months and by the end of the 12-month feeding study, ALL (100%) the monkeys developed certain metabolic syndrome components including body adiposity, insulin resistance, and dyslipidemia and four monkeys (15%) developed type 2 diabetes mellitus.

Increased fructose consumption from fruits increases metabolic syndrome risk: A cross-sectional population based study on 2537 subjects (45% men) aged 19-70 y has shown that higher consumption of dietary fructose may have adverse metabolic effects and increase the risks for metabolic syndrome.

Fructose (Fruit Sugar) is a more important cause for metabolic disorders like diabetes, hypertension, fatty liver disease, obesity

Fructose in fruits can increase obesity: A new study reports that when fructose was consumed, absolute lipogenesis was 2-fold greater and that an early stimulation of lipogenesis after fructose, consumed in a mixture of sugars, augments subsequent postprandial lipemia. Acute intake of fructose stimulates lipogenesis and may create a metabolic milieu that enhances subsequent esterification of fatty acids flowing to the liver to elevate TG synthesis postprandially.

Energy Drinks Pose Serious Health Risks for Young People: According to a review of scientific literature and Internet sources, published in Pediatrics, energy drinks that contain caffeine, taurine, sugars and sweeteners, herbal supplements etc., are regularly consumed by 30% to 50% of children, adolescents, and young adults and and are associated with risks for serious adverse health effects such as liver damage, kidney failure, respiratory disorders, agitation, confusion, seizures, psychotic conditions, nausea, vomiting, abdominal pain, rhabdomyolysis, tachycardia, cardiac dysrhythmias, hypertension, myocardial infarction, heart failure, and death.

Metabolic disorders striking the young: Should the stress be on ‘Stress’ or on Food? Many reports emerging from India reveal increasing incidence of metabolic syndrome disorders in young children and many things such as stress at school, sedentary life style, computers, TV, genes and junk food have been blamed. Some have even advised the kids to stop schooling and do yoga for relaxation! Is it not ironical that the so called experts who sought changes in our school education, so as to make it less stressful, now blame the changed methodology for increasing stress? In blaming many things, the strongest reason is bound to be missed: and that reason is the FOOD! See The Young Are Ageing. Outlook Sep 13, 2010 Full Text | Delhi kids suffer from adult ailments!

Apple Or Pear-Shaped Body Type Equally Dangerous: A study of 220,000 people suggests that being obese – having a body mass index (BMI) of 30 or more – is a major risk factor for heart disease, but found the distribution of fat on the body has no impact on that risk.

Metabolic Syndrome May be Due to Disease Causing Fat Cells: UC Davis Health System researchers have reported a novel observation that subcutaneous fat of MetS has increased macrophage recruitment with cardinal crown-like structure features and contributes to the increased cellular inflammation that produces increased levels of biomarkers that are correlated with both insulin resistance and low-grade inflammation.
