Is corn syrup causing the obesity epidemic and harming the brain, too?

Follow in my footsteps as I undertake an ongoing experiment to recover completely from eczema, gut problems and an aching body. I intend to achieve this by not eating anything that is processed, transported over distance, killed, frozen or packaged, (known as dead food). What I am attempting is well proven methodology based on ancient wisdom of the Essenes and Edmond Bordeaux Szekely who successfully cured many hundreds of people of their sickness and disease, plus the wonderful work of Dr Ann Wigmore. I intend to remain fit healthy into old age by practicing yoga and exercising, eating only healthy organic food, fruit, vegetables, nuts, and grain, plus seed sprouts. Doing this I will also save money and leave a light footprint.

Day 38

On the weekend I was talking to my daughter in law about obesity in this country and she said that although Australia has the highest level of obesity per number of population, In America she said ( where she visited recently) the people are huge. One reason she said was the consumption of corn syrup, so I have decided to investigate and found this.

Foods that appear to be nutritious could actually be destroying your brainpower. The culprit? A common ingredient slipped into many "healthy" foods, including baby food, applesauce, and oatmeal, a breakfast favourite. Researchers at UCLA found that ingesting foods and drinks containing fructose, a component of the ingredient high-fructose corn syrup and sugar, for just six weeks caused troubling changes in brain function. "Our findings illustrate that what you eat affects how you think," says Fernando Gomez-Pinilla, PhD, a professor of neurosurgery and integrative biology and physiology at UCLA. "Eating a high-fructose diet over the long term alters your brain's ability to learn and remember information."

While high-fructose corn syrup and added sugar is rampant in soda and candy products, it also hides out in some seemingly innocuous items like bread, juices, ketchup, and instant oatmeal. (Previous studies have found high-fructose corn syrup is sometimes contaminated with mercury.) Most often associated with obesity and diabetes, this latest study, appearing in the Journal of Physiology, shows that too much fructose can harm the brain, too. This could be leading to an all-out American brain drain, given that the average citizen downs about 35 pounds of high-fructose corn syrup every year.

Quoted from: The American Journal of Clinical Nutrition.

Obesity is a major epidemic, but its causes are still unclear. In this article, we investigate the relation between the intake of high-fructose corn syrup (HFCS) and the development of obesity. We analysed food consumption patterns by using US Department of Agriculture food consumption tables from 1967 to 2000. The consumption of HFCS increased > 1000% between 1970 and 1990, far exceeding the changes in intake of any other food or food group. HFCS now represents > 40% of caloric sweeteners added to foods and beverages and is the sole caloric sweetener in soft drinks in the United States. Our most conservative estimate of the consumption of HFCS indicates a daily average of 132 kcal for all Americans aged ≥ 2 y, and the top 20% of consumers of caloric sweeteners ingest 316 kcal from HFCS/d. The increased use of HFCS in the United States mirrors the rapid increase in obesity. The digestion, absorption, and metabolism of fructose differ from those of glucose. Hepatic metabolism of fructose favors de novo lipogenesis. In addition, unlike glucose, fructose does not stimulate insulin secretion or enhance leptin production. Because insulin and leptin act as key afferent signals in the regulation of food intake and body weight, this suggests that dietary fructose may contribute to increased energy intake and weight gain. Furthermore, calorically sweetened beverages may enhance caloric overconsumption. Thus, the increase in consumption of HFCS has a temporal relation to the epidemic of obesity, and the overconsumption of HFCS in calorically sweetened beverages may play a role in the epidemic of obesity.
