[NaturalNews] With so much conflicting information out there about which foods are healthy and which foods are not, it can be difficult for many people to determine how best to approach a healthy lifestyle that includes eating well. But a good place to start is to avoid these seven toxic foods, beverages, and additives that are quite common in the American diet.
Diet sodas and beverages sweetened with artificial chemicals. One of the more common dietary misconceptions in mainstream society today is the idea that “diet” beverages are somehow healthier than their sugar-sweetened beverages. Aspartame (NutraSweet, Equal) saccharin (Sweet’N Low), and sucralose (Splenda) are among the more popular artificial sweeteners used in many diet sodas, juices, chewing gums, and other foods (http://www.naturalnews.com).
Not only are artificial sweeteners bad for your health (http://www.naturalnews.com), but they also tend to promote obesity (http://www.naturalnews.com/022785.html). If you want to protect yourself against chronic illness and toxicity — aspartame literally converts to formaldehyde in the body and causes metabolic acidosis — it is best to stick with either raw sugars or natural sugar substitutes like pure stevia extract.
High-fructose corn syrup (HFCS), the silent killer. It is not really much of a secret anymore that HFCS, despite all the corn industry shilling, is a toxic sweetener that should be avoided (http://www.naturalnews.com/hfcs.html). Since it is linked to obesity, brain damage, low IQ, and even mercury poisoning, avoiding all foods that contain HFCS — this can include breads, cereals, and other seemingly innocuous foods — will do wonders for your health.
Most vegetable oils, including hydrogenated and ‘trans’ fat varieties. The misdirected war on saturated fats has convinced millions of people that unsaturated vegetable oils are a healthy alternative. Not only do many vegetables oils turn rancid quickly, which means they are toxic (http://healthwyze.org), but many of them also contain high levels of omega-6 fatty acids which, apart from omega-3 fatty acids, can cause severe health problems like heart disease and cancer. (http://www.naturalnews.com/022860.html)
Many vegetable oils are also derived from genetically-modified organisms (GMOs), including canola, soy, and corn oils. These same oils are often hydrogenated as well, a process that turns them into heart-destroying solid oils. Avoiding these and sticking instead to healthy fats like grass-fed butter, coconut oil, olive oil, and hemp oil will greatly improve your health and lower your risk of disease.
White bread, pasta, and other refined flour foods. They are cheap, plentiful, and come in hundreds of varieties. But white breads, pastas, and other foods made from refined flour are among the top health destroyers in America today. Not only are most white flour products carcinogenic because they are bleached and bromated, but they also lack vital nutrients that are stripped away during processing. Avoid them, and all processed wheat products if possible, to optimize your health.
Monosodium glutamate (MSG), carrageenan, and refined salt. Often hidden in foods under deceptive names (http://www.truthinlabeling.org/hiddensources.html), MSG is a pervasive salt chemical you will want to avoid that is linked to causing headaches, heart problems, brain damage, and other problems. Carrageenan, another chemical additive often hidden in “natural” and organic foods like nut milks and lunch meats, is similarly worth avoiding, as it can cause gastrointestinal upset and colon cancer. (http://www.cornucopia.org)
And processed salt, which is added to just about everything these days, lacks the trace minerals normally present in sea and earth salts, which means it ends up robbing your body of these vital nutrients (http://www.naturalnews.com/028724_Himalayan_salt_sea.html). Hypertension, cardiovascular disease, and stroke are just a few of the many conditions that can result from refined salt intake, so your best bet is to stick with unrefined sea salts and other full-spectrum salts.

[NaturalNews] Many health-minded individuals understand that eating fried or overcooked foods is unhealthy due to the chemical transition of normally stable fats to trans fats that have been shown to dramatically increase heart attack risk. Researchers from the University of the Basque in Spain publishing in the journal Food Chemistry are the first to discover compounds released from common cooking oils that significantly increase the risk of neurologic degenerative diseases and a variety of different cancers.
Breakdown chemical structures known as aldehydes are formed in cooked vegetable oils such as sunflower oil when heated to normal frying temperatures,and are also released into the air where they can be inhaled. Alternate food preparation methods such as roasting, steaming and broiling are safe methods of cooking foods to avoid the dangerous release of aldehydes andprovide a shield against cancer-forming particles and neurodegenerative decline.
Prior studies have identified the health degrading nature of aldehydes, where their presence in organisms is linked to different types of cancer and neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Researchers also know that these compounds remain in vegetable oils after they have been used to fry foods and wanted to determine how they interact with proteins, hormones and enzymes in the body to impede its correct functioning.
Many common vegetable oils produce dangerous aldehydes when heated
The study team heated three types of oil (olive, sunflower and flaxseeds) in an industrial deep fryer at 190 degrees Celsius for a period of forty hours (twenty hours was used for the flaxseed oil). This length of time was used to approximate oils used commercially at a restaurant where fryers remain heated for extended periods of time. The oils were then analyzed using gas chromatography/mass spectrometry techniques.
Researchers found that the sunflower and flaxseed oils degraded significantly and are the ones that create the most toxic aldehydes in the least amount of frying time. These oils are high in polyunsaturated fats (linoleic and linolenic) and breakdown quickly to form the health-demoting aldehyde compounds that permeate the air and penetrate into the food. Olive oil, known to be high in monounsaturated fat, generates aldehydes to a lesser degree and after cooking much longer.
The research team concluded “The fact that significant concentrations of these toxic compounds were found in some oils … is a cause of concern for human health. “Although the scientists did not use coconut oil in their tests, studies have shown that the medium-chain fatty acid does not rapidly convert to deadly trans fats when heated, and may be less likely to produce aldehydes when compared to other vegetable oils. While fried foods are not part of a healthy eating plan, it is important to avoid cooking with low flash-point oils that produce aldehydes and increase the risk of neurologic disorders and cancer.
