The Five Absolute Worst Foods You Can Eat
By Dr. Mercola October 18, 2003
Doughnuts are fried, full of sugar and white flour and most all varieties contain trans fat. Store-bought doughnuts are made up of about 35 percent to 40 percent trans fat, and an average doughnut contains about 200 to 300 calories, mostly from sugar, and few other nutrients.
Trans fats, found largely in commercially prepared baked and fried foods, have become notorious in recent years because they not only raise "bad" LDL cholesterol, but also lower levels of heart-healthy HDL cholesterol. High trans-fat intake has been linked to coronary heart disease, in which fatty plaques build up in the heart arteries, sometimes leading to a heart attack.
One can of soda has about 10 teaspoons of sugar, typically in the form of high fructose corn syrup, 150 calories, 30 to 55 mg of caffeine, and is loaded with artificial food colors and sulphites. I can't think of any good reason to ever drink it. The diet varieties are even worse, as they are filled with harmful artificial sweeteners like aspartame and/or sucralose.
Studies have linked soda to osteoporosis, obesity, tooth decay and heart disease, yet the average American drinks an estimated 50 gallons of soft drinks each year. Plus, drinking all that sugar will likely suppress your appetite for healthy foods, which pave the way for nutrient deficiencies.
(3) French Fries (and Nearly All Commercially Fried Foods)
Potatoes are bad enough when consumed in their raw state, as their simple sugars are rapidly converted to glucose that raises insulin levels and can devastate your health. But when they are cooked in trans fat at high temperatures, all sorts of interesting and very unpleasant things occur.
Anything that is fried, even vegetables, has the issue of trans fat and the potent cancer-causing substance acrylamide. Animal studies have shown that exposure to acrylamide increases the risk of several types of cancer, and the International Agency for Research on Cancer considers acrylamide a "probable human carcinogen." It has also been linked to nerve damage and other neurotoxic effects, including neurological problems in workers handling the substance.
While this chemical can be formed in many foods when they're heated to a temperature above 120 degrees Celsius (248 degrees F), French fries and potato chips are the biggest offenders.
Most commercial chips, and this includes corn chips, potato chips, tortilla chips, you name it, are high in trans fat. Many also contain genetically engineered ingredients. Fortunately, some companies have caught on to the recent media blitz about the dangers of trans fat and have started to produce chips without trans fat. However, the high temperatures used to cook them can still cause the formation of carcinogenic substances like acrylamide, and this risk remains even if the trans fat is removed.
“Natural” chips are increasingly popular, but it’s important to realize that this means very little in terms of its health impact. A fried, genetically engineered corn chip is still going to wreak havoc in your body—even if it’s low in trans fat.
(5) Fried Non-Fish Seafood
This category represents the culmination of non-healthy aspects of food. Fried shrimp, clams, oysters, lobsters, and so on have all the issues of trans fat and acrylamide mentioned above, plus an added risk of mercury.
Seafood is loaded with toxic mercury and shellfish like shrimp and lobsters can be contaminated with parasites and resistant viruses that may not even be killed with high heat. These creatures, considered scavenger animals, consume foods that may be harmful for you. Farmed seafood may be even worse than wild-caught, as they’re fed concoctions of antibiotics and other synthetic chemicals.
Eating these foods gives you a quadruple dose of toxins--trans fat, acrylamide, mercury, and possibly parasites or viruses--with every bite. The only fish I now eat is wild red Alaskan salmon that has been proven through independent lab testing to be virtually free of harmful levels of mercury and other contaminants.
