Many foods have been heavily promoted as being healthy when they are nothing more than pernicious junk foods. In the featured article, Clean Plates1 founder Jared Koch shared his list of nine staple foods that are far less “good for you” than you’ve been led to believe.
Here, I expand on the selections that are mentioned in the featured article.
1. Canned Tomatoes
Many leading brands of canned foods contain BPA — a toxic chemical linked to reproductive abnormalities, neurological effects, heightened risk of breast and prostate cancers, diabetes, heart disease and other serious health problems. According to Consumer Reports’ testing, just a couple of servings of canned food can exceed the safety limits for daily BPA exposure for children.
High acidity — a prominent characteristic of tomatoes – causes BPA to leach into your food. To avoid this hazardous chemical, avoid canned foods entirely and stick to fresh fruits and vegetables, or switch over to brands that use glass containers instead—especially for acidic foods like tomatoes.
2. Processed Meats
As Koch warns, processed deli meats like salami, ham, and roast beef are typically made with meats from animals raised in confined animal feeding operations (CAFOs).
This means they’re given growth hormones, antibiotics and other veterinary drugs, and raised in deplorable conditions that promote disease, these meats are also filled with sodium nitrite (a commonly used preservative and antimicrobial agent that also adds color and flavor) and other chemical flavorings and dyes.
Nitrites can be converted into nitrosamines in your body, which are potent cancer-causing chemicals. Research has linked nitrites to higher rates of colorectal, stomach and pancreatic cancer. But that’s not all. Most processed deli meats also contain other cancer-promoting chemicals that are created during cooking. These include:
- Heterocyclic Amines (HCAs) which are hazardous compounds created in meats and other foods that have been cooked at high temperatures. According to research, processed meats are clearly associated with an increased risk of stomach, colon and breast cancers.
- Polycyclic Aromatic Hydrocarbons (PAHs): Many processed meats are smoked as part of the curing process, which causes PAHs to form. PAHs can also form when grilling. When fat drips onto the heat source, causing excess smoke, and the smoke surrounds your food, it can transfer cancer-causing PAHs to the meat.
- Advanced Glycation End Products (AGEs): When food is cooked at high temperatures—including when it is pasteurized or sterilized—it increases the formation of AGEs in your food. AGEs build up in your body over time leading to oxidative stress, inflammation and an increased risk of heart disease, diabetes and kidney disease.
The truth is, processed meats are not a healthful choice for anyone and should be avoided entirely, according to a 2011 review of more than 7,000 clinical studies examining the connection between diet and cancer. The report was commissioned by The World Cancer Research Fund2 (WCRF) using money raised from the general public. Therefore the findings were not influenced by any vested interests, which makes it all the more reliable.
It’s the biggest review of the evidence ever undertaken, and it confirms previous findings: Processed meats increase your risk of cancer, especially bowel cancer, and NO amount of processed meat is “safe.” You’re far better off ditching the deli meats and opting instead for fresh organically-raised grass-fed meats, or wild caught salmon.
The unfortunate result of the low-fat diet craze has been the shunning of healthful fats such as butter, and public health has declined as a result of this folly. There are a myriad of unhealthy components to margarine and other butter impostors, including:
- Trans fats: These unnatural fats in margarine, shortenings and spreads are formed during the process of hydrogenation, which turns liquid vegetable oils into a solid fat. Trans fats contribute to heart disease, cancer, bone problems, hormonal imbalance and skin disease; infertility, difficulties in pregnancy and problems with lactation; and low birth weight, growth problems and learning disabilities in children. A US government panel of scientists determined that man-made trans fats are unsafe at any level.
- Free radicals: Free radicals and other toxic breakdown products are the result of high temperature industrial processing of vegetable oils. They contribute to numerous health problems, including cancer and heart disease.
- Emulsifiers and preservatives: Numerous additives of questionable safety are added to margarines and spreads. Most vegetable shortening is stabilized with preservatives like BHT.
- Hexane and other solvents: Used in the extraction process, these industrial chemicals can have toxic effects.
Good-old-fashioned butter, when made from grass-fed cows, is rich in a substance called conjugated linoleic acid (CLA). Much of the reason why butter is vilified is because it contains saturated fat. If you’re still in the mindset that saturated fat is harmful for your health, then please read the Healthy Fatssection of my Optimized Nutrition Plan to learn why saturated fat is actually good for you.
4. Vegetable Oils
Of all the destructive foods available to us, those made with heated vegetable oils are some of the worst. Make no mistake about it–vegetable oils are not the health food that you were lead to believe they were. This is largely due to the fact that they are highly processed, and when consumed in massive amounts, as they are by most Americans, they seriously distort the important omega-6 to omega-3 ratio. Ideally, this ratio is 1:1.
Anytime you cook a food, you run the risk of creating heat-induced damage. The oils you choose to cook with must be stable enough to resist chemical changes when heated to high temperatures, or you run the risk of damaging your health. One of the ways vegetable oils can inflict damage is by converting your good cholesterol into bad cholesterol—by oxidizing it. When you cook with polyunsaturated vegetable oils (such as canola, corn, and soy oils), oxidized cholesterol is introduced into your system.
As the oil is heated and mixed with oxygen, it goes rancid. Rancid oil is oxidized oil and should NOT be consumed—it leads directly to vascular disease. Trans-fats are introduced when these oils are hydrogenated, which increases your risk of chronic diseases like breast cancer and heart disease.
So what’s the best oil to cook with?
Of all the available oils, coconut oil is the oil of choice for cooking because it is nearly a completely saturated fat, which means it is much less susceptible to heat damage. And coconut oil is one of the most unique and beneficial fats for your body. For more in-depth information about the many benefits of coconut oil, please see this special report. Olive oil, while certainly a healthful oil, is easily damaged by heat and is best reserved for drizzling cold over salad.
5. Microwave Popcorn
Perfluoroalkyls, which include perfluorooctanoic acid (PFOA), and perfluorooctane sulfonate (PFOS), are chemicals used to keep grease from leaking through fast food wrappers, are being ingested by people through their food and showing up as contaminants in blood. Microwave popcorn bags are lined with PFOA, and when they are heated the compound leaches onto the popcorn.
These chemicals are part of an expanding group of chemicals commonly referred to as “gender-bending” chemicals, because they can disrupt your endocrine system and affect your sex hormones. The EPA has ruled PFCs as “likely carcinogens,” and has stated that PFOA “poses developmental and reproductive risks to humans.” Researchers have also linked various PFCs to a range of other health dangers, such as:
- Infertility – A study published in the journal Human Reproduction3 found that both PFOA and PFOS (perfluorooctane sulfonate), dramatically increased the odds of infertility. PFOA was linked to a 60 to 154 percent increase in the chance of infertility.
- Thyroid disease – A 2010 study4 found that PFOA can damage your thyroid function. Individuals with the highest PFOA concentrations were more than twice as likely to report current thyroid disease, compared to those with the lowest PFOA concentrations. Your thyroid contains thyroglobulin protein, which binds to iodine to form hormones, which in turn influence essentially every organ, tissue and cell in your body. Thyroid hormones are also required for growth and development in children. Thyroid disease, if left untreated, can lead to heart disease, infertility, muscle weakness, and osteoporosis.
- Cancer – PFOA has been associated with tumors in at least four different organs in animal tests (liver, pancreas, testicles and mammary glands in rats), and has been associated with increases in prostate cancer in PFOA plant workers.
- Immune system problems – Several studies by scientists in Sweden indicate that PFCs have an adverse effect on your immune system. As described in a report on PFCs by the Environmental Working Group (EWG), PFOA was found to decrease all immune cell subpopulations studied, in the thymus and spleen, and caused immunosupression.
- Increased LDL cholesterol levels – A 2010 study in the Archives of Pediatric & Adolescent Medicine5 found that children and teens with higher PFOA levels had higher levels of total cholesterol and LDL or “bad” cholesterol, while PFOS was associated with increased total cholesterol, including both LDL cholesterol and HDL or “good” cholesterol.
I strongly recommend avoiding any product you know containing these toxic compounds, particularly non-stick cookware, but also foods sold in grease-proof food packaging, such as fast food and microwave popcorn. Clearly, if you’re eating fast food or junk food, PFCs from the wrapper may be the least of your problems, but I think it’s still important to realize that not only are you not getting proper nutrition from the food itself, the wrappers may also add to your toxic burden.
