#1 Added Sugars & Syrups
- Fructose elevates uric acid, which decreases nitric oxide, raises angiotensin, and causes your smooth muscle cells to contract, thereby raising your blood pressure and potentially damaging your kidneys.
- Increased uric acid also leads to chronic, low-level inflammation, which has far-reaching consequences for your health. For example, chronically inflamed blood vessels lead to heart attacks and strokes; also, a good deal of evidence exists that some cancers are caused by chronic inflammation. (See the next section for more about uric acid.)
- Fructose tricks your body into gaining weight by fooling your metabolism—it turns off your body's appetite-control system. Fructose does not appropriately stimulate insulin, which in turn does not suppress ghrelin (the "hunger hormone") and doesn't stimulate leptin (the "satiety hormone"), which together result in your eating more and developing insulin resistance.2
- Fructose rapidly leads to weight gain and abdominal obesity ("beer belly"), decreased HDL, increased LDL, elevated triglycerides, elevated blood sugar, and high blood pressure—i.e., classic metabolic syndrome.
- Fructose metabolism is very similar to ethanol metabolism, which has a multitude of toxic effects, including NAFLD (non-alcoholic fatty liver disease). It's alcohol without the buzz.
#2 Unhealthy Fats ~ Hydrogenated, Partially Hydrogenated, Trans & Saturated
If you do eat animal products, organic is vital. The difference in organic and non-organic animal foods is significant. As an example, look at the difference between organic and non-organic eggs. Our body functions best when we eat an equal balance of the two fatty acids: omega-6 and omega-3. Having too much omega-6 and too little omega-3 leads to numerous health problems, including generalized inflammation, high blood pressure, depressed immune function, weight gain, an irritated intestinal tract, and a tendency to form blood clots. An organic egg, one that comes from a hen allowed to eat green plants and insects, contains an optimal ratio of omega-6 and omega-3 fatty acids of 1:1. A commercial supermarket egg from a hen that is fed mainly grain in a factory-farm environment has a ratio closer to 15 or 20:1 which creates an internal imbalances that leads to inflammation and chronic disease.
#3 Food Additives ~ Dyes, Colorings & Flavorings
Natural flavorings are often made using just as many chemical manipulations as artificial flavorings. In some cases, there are no distinguishable differences between natural and artificial flavorings. The term “natural” is able to be used because at some point a natural substance was used, but this does not indicate the end product is in any way natural. MSG, monosodium glutamate, is a common food additive used in processed foods as a flavor enhancer that tricks the taste buds into believing there is more of a flavor then is actually present. MSG has been shown to cause headaches, nausea, weakness, difficulty breathing, drowsiness, rapid heartbeat and chest pains in many.
Artificial colorings added to processed foods also pose a serious health risk especially to children. In 2007, a study published in the Lancet found a mix of four artificial food colors and preservatives, including sodium benzoate, aggravated hyperactivity in two groups of children that did not have ADHD. The two groups were a group of 3 year olds and a group of 8-9 year olds. Another study published in Discover magazine in 2008, found that common food additives were shown to double children’s hyperactivity. The European Union, who tends to be light years ahead of the U.S.’s FDA in health matters, acted to place warning labels that state “May have an adverse effect on the activity and attention in children.” on foods containing six artificial colors including Yellow #5, #10, #6 and Red #3, #7 and #40, commonly used here in the U.S. without any warning to consumers.
Dyes, colorings and flavorings added to foods cause a myriad of health problems. Citrus Red 2, Red 3, Red 40, Yellow 5, Yellow 6, Blue 1, Blue 2 and Green 3, --which are some of the most commonly used artificial food colorings--have all been identified as being, or being contaminated with, potential cancer-causing chemicals, according to the Center for Science in the Public Interest. And Blue 1, Red 40, Yellow 5, and Yellow 6 are known to trigger reactions in those with allergies.
Food additives have been shown to cause other health problems outside of hyperactivity in children. A Paper published in the Canadian Journal of Gastroenterology theorizes that the increase in Irritable Bowel Disorders in Canada, in recent years, may be related to the impairments of digestive proteases, caused by the inhibition of healthy gut bacteria by dietary chemicals. Especially noted, in the study, were the use of saccharin and sucralose. The study showed that these food additives increased the pH level of the intestines, thereby reducing the amount of good bacteria in the intestine by over 50%.
The World's Healthiest Foods describes the disastrous health consequences of a couple other common food preservatives, BHT and BHA.
"Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are currently being investigated for their potential to damage genetic material and therefore promote cancer. BHT has been shown to induce tumors in the stomach and liver in animals, when used at high levels. Although this preservative is allowed in foods at a low level per food, it is one of the most common preservatives, and is present in many processed foods. The amount consumed in the entire diet may be higher than the "permitted" level per food and remains a concern by many scientists."
