Diet is one of those things we are all told contradictory opinions about. The raw food diet, the blood type diet, the Paleolithic diet, the Atkins diet, there are so many strands of belief claiming to be the best diet mankind has ever known. While we don’t necessary believe that one same diet is appropriate for every single person, we strongly believe in avoiding these 9 foods, no matter which school of dietary thought you swim in.
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
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 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). CLA is not only known to help fight cancer and diabetes, it may even help you to lose weight, which cannot be said for its trans-fat substitutes.
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.
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. 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, thyroid disease, cancer, immune system problems, and increased LDL cholesterol levels.
6. Non-Organic Potatoes and Other Fresh Produce Known for High Pesticide Contamination
Of the 48 different fruit and vegetable categories tested by the Environmental Working Group for the 2013 guide, the following 15 fruits and vegetables had the highest pesticide load, making them the most important to buy or grow organically:
Apples Celery Cherry tomatoes Cucumbers Grapes Hot peppers Nectarines (imported) Peaches Potatoes Spinach Strawberries Sweet bell peppers Kale Collard greens Summer squash
In contrast, the following foods were found to have the lowest residual pesticide load, making them the safest bet among conventionally grown vegetables. Note that sweet corn has a tendency to be genetically engineered (GE). If you’re unsure of whether the sweet corn you’re buying is GE, opt for organic varieties:
Asparagus Avocado Cabbage Cantaloupe Sweet corn (non-GMO) Eggplant Grapefruit Kiwi Mango Mushrooms Onions Papayas Pineapple Sweet peas (frozen) Sweet potatoes
7. Table Salt
Processed salt (regular ‘table salt’ ) is 98 percent sodium chloride, and the remaining two percent comprises man-made chemicals, such as moisture absorbents, and a little added iodine. These are dangerous chemicals like ferrocyanide and aluminosilicate. Some European countries, where water fluoridation is not practiced, also add fluoride to table salt
Natural salt is about 84 percent sodium chloride. The remaining 16 percent of natural salt consists of other naturally occurring minerals, including trace minerals like silicon, phosphorous and vanadium
Given that salt is absolutely essential to good health, we recommend switching to a pure, unrefined salt. One of the best varieties is Himalayan salt. It’s hand-mined, hand-washed, and minimally processed. Himalayan salt is only 85 percent sodium chloride, the remaining 15 percent contains 84 trace minerals from our prehistoric seas. Unrefined natural salt is important to many biological processes, including:
- Being a major component of your blood plasma, lymphatic fluid, extracellular fluid, and even amniotic fluid
- Carrying nutrients into and out of your cells
- Maintain and regulate blood pressure
- Increasing the glial cells in your brain, which are responsible for creative thinking and long-term planning
- Helping your brain communicate with your muscles, so that you can move on demand via sodium-potassium ion exchange
8. Soy Protein Isolate and Other Unfermented Soy Products
One of the worst problems with soy comes from the fact that 90 to 95 percent of soybeans grown in the US are genetically engineered (GE). In Australia, genetically engineered soybeans are extremely common. Genetically engineered soybeans are designed to be “Roundup ready,” which means they’re engineered to withstand otherwise lethal doses of herbicide.
The active ingredient in Roundup herbicide is called glyphosate, which is responsible for the disruption of the delicate hormonal balance of the female reproductive cycle. What’s more, glyphosate is toxic to the placenta, which is responsible for delivering vital nutrients from mother to child, and eliminating waste products. Once the placenta has been damaged or destroyed, the result can be miscarriage. In those children born to mothers who have been exposed to even a small amount of glyphosate, serious birth defects can result.
Soy protein isolate can be found in protein bars, meal replacement shakes, bottled fruit drinks, soups and sauces, meat analogs, baked goods, breakfast cereals and some dietary supplements.
Besides soy protein isolate, ALL unfermented soy products are best avoided if you value your health. Thousands of studies have linked unfermented soy to malnutrition, digestive distress, immune-system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility—even cancer and heart disease.
The only soy with health benefits is organic soy that has been properly fermented, and these are the only soy products I ever recommend consuming. After a long fermentation process, the phytate and “anti-nutrient” levels of soybeans are reduced, and their beneficial properties become available to your digestive system.
9. Artificial Sweeteners
Contrary to popular belief, studies have found that artificial sweeteners such as aspartame can stimulate your appetite, increase carbohydrate cravings, and stimulate fat storage and weight gain. In one of the most recent of such studies, saccharin and aspartame were found to cause greater weight gain than sugar.
Aspartame is perhaps one of the most problematic. It is primarily made up of aspartic acid and phenylalanine. The phenylalanine has been synthetically modified to carry a methyl group, which provides the majority of the sweetness. That phenylalanine methyl bond, called a methyl ester, is very weak, which allows the methyl group on the phenylalanine to easily break off and form methanol.
You may have heard the claim that aspartame is harmless because methanol is also found in fruits and vegetables. However, in fruits and vegetables, the methanol is firmly bonded to pectin, allowing it to be safely passed through your digestive tract. Not so with the methanol created by aspartame; there it’s not bonded to anything that can help eliminate it from your body.
Methanol acts as a Trojan horse; it’s carried into susceptible tissues in your body, like your brain and bone marrow, where the alcohol dehydrogenase (ADH) enzyme converts it into formaldehyde, which wreaks havoc with sensitive proteins and DNA. All animals EXCEPT HUMANS have a protective mechanism that allows methanol to be broken down into harmless formic acid. This is why toxicology testing on animals is a flawed model. It doesn’t fully apply to people.
Guidelines for Healthy Food
Whatever food you’re looking to eat, whether organic or locally grown, from either your local supermarket or a farmer’s market, the following are signs of a high-quality, healthy food.
- It’s grown without pesticides and chemical fertilizers (organic foods fit this description, but so do some non-organic foods)
- It’s not genetically engineered
- It contains no added growth hormones, antibiotics, or other drugs
- It does not contain artificial anything, nor any preservatives
- It is fresh (if you have to choose between wilted organic produce or fresh conventional produce, the latter may still be the better option as freshness is important for optimal nutrient content)
- It was not grown in a factory farm
- It is grown with the laws of nature in mind (meaning animals are fed their native diets, not a mix of grains and animal byproducts, and have free-range access to the outdoors)
