Why High Fructose Corn Syrup is More Fattening than Sugar

--HFCS = a sweetener found in most sodas and many other processed foods.
--HFCS contains lots of unbound fructose
--high-fructose diet-->hypertriglyceridemia, nonalcoholic fatty liver disease (NAFLD), and insulin resistance
--fructose consumption decreases signaling to your CNS by hormones leptin and insulin
--leptin signals "satiety", so you never feel fed, you stay hungry !!!!
--fructose is converted to fat by the liver much more easily than glucose is (ie is more lipogenic)
--sugars usually go to liver and may be stored (as glycogen), burned, or turned to fat
--fructose converts into adipose and triglycerides, do not pass go, do not collect $200
--overconsumption of HFCS-->nonalcoholic fatty liver disease (NAFLD)-->hepatic insulin resistance & type II diabetes
--new diabetes diagnoses up by 90 percent in the last decade
--1/4 of all Americans are either diabetic or pre-diabetic
--rising HFCS consumption is linked to US epidemics of obesity, DM & metabolic syndrome
--the HFCS industry persists in claiming that their sweetener is just like sugar, and have studies to prove it, but they paid for those studies
--#1 source of calories in America is high fructose corn syrup in soda (approx 40g/can)
--40g is more than the AMA’s recommended daily max for ALL caloric sweeteners
--HFCS is in all kinds of processed, pre-packaged foods too, even non-sweet foods
--US use of HFCS increased 10,673% in 35 years: 1970-2005, according to USDA Dietary Assessment of Major Trends in U.S. Food Consumption report
--processed foods account for > 90% of US food budget
--average of 1/4 of calories consumed in US is in added sugars, mostly HFCS
--11 different carbonated soft drinks containing HFCS were tested for other chemicals
--these 11 have ‘astonishingly high’ levels of reactive carbonyls: undesirable and highly-reactive compounds assoc w/ “unbound” fructose and glucose molecules-->may cause tissue damage
--reactive carbonyls not present in table sugar, its fructose and glucose are “bound”
--reactive carbonyls elevated in blood of diabetics, linked to health complications
--1 can soda contains about 5x the concentration of reactive carbonyls than what's in the blood of an adult with diabetes (so what?)
--HFCS-->sig increase to triglycerides and LDL
--high triglycerides = heart disease risk
--HFCS is empty calories, no nutritional content whatsoever, sucks nutrients from your bod
--unbound fructose interferes w/ heart's use magnesium, copper and chromium
--whole fruit contains some fructose but it has enzymes, vitamins and minerals in it too
--HFCS almost always made from genetically modified corn
--GMO corn increases your risk of developing corn allergies

Cell Metabolism March 2009; 9(3):252-64

--mice fed a high-fructose diet could be protected from insulin resistance if a gene known as transcriptional coactivator PPARg coactivator-1b (PGC-1b) was "knocked down" in the animals' liver and fat tissue
--this gene (PGC-1b) regulates the activity of several other genes, including one that builds fat in the liver
--if they start using drugs to adjust people's PGC-1b gene expression and prevent type II diabetes, they'll be missing the point that you could just stop consuming so much fructose instead of taking a drug


majority of HFCS made from genetically engineered corn
corn syrup that has undergone an enzymatic process to increase its fructose level
then mixed with pure corn syrup (100% glucose)-->final form
can be manipulated-->fruct=gluc, or up to 80%fruct/20%gluc
fructose ingestion increases uric acid levels-->heart disease
raises levels of lactic acid-->mb life threat at extreme levels
high sucrose diet may alter intracellular metabolism-->oxidation-->accelerate aging
rats given fructose had changes in skin collagen
fruct metabolized by the liver-->pancreas not produce normal amount of insulin
fructose converts to fat more easily than other sugars-->obesity
fructose consumption-->increased TG levels
damaging effects w/ copper deficiency, inhibits copper metabolism
poor copper metab-->anemia, CT issues, MIs, high chol, dysglycemia, thyroid disorders
