Phthalates in Food: 7 Ways to Reduce Your Exposure



You probably know that some plastic toys—like the now infamous rubber ducky—contain the hormone-disrupting, birth-defect-causing, probably-carcinogenic plasticizers known as phthalates. You may have even heard that this group of chemicals is also found in the fragrance of your favorite personal care products.

Most of my clients are surprised to learn, though, that the single largest source of phthalate exposure comes from our food and water supply—and this is not just true for people eating microwaved meals from plastic trays. Almost all of us have phthalates in our systems, and a recent study showed that when fasting, people’s phthalate levels dropped by five to ten times within the first 24 hours without food. This is not to say we should stop eating–but we should get phthalates out of what we eat!

Until phthalates are banned for good, we can take matters into our own hands in several ways.  Here’s how:
  1. Avoid putting your food in or on plastic. Even BPA- or phthalate-free plastic may leach harmful chemicals, and it’s impossible to know for sure which containers, wraps, or baggies may contain phthalates without testing. Opt for glass food storage containers, and choose bottles and sippy cups that are made of stainless steel, silicone, or glass. Try zippered cloth bags instead of plastic food storage bags, and try to source meats and cheeses that come wrapped in paper whenever possible.
     
  2. If you must use plastic, keep it out of the microwave and dishwasher. When plastic is heated, it leaches more chemicals, and phthalates are no exception. Even the hot water of the dishwasher causes plastic to degrade and release toxins, so if you do use plastic food-storage containers, replace them often.
     
  3. Eat more plants. People who eat diets rich in plant foods—fruits, vegetables, beans, grains, nuts, and seeds—have lower levels of phthalates in their blood than do people who eat more animal foods. Substituting out just a few meat- and dairy-heavy meals a week with vegan ones can lower your family’s phthalate levels. If you’re worried about protein, try beans. For fats, add nuts or avocado. For calcium, choose kale or collard greens.
     
  4. Eat organic and grass-fed produce, meat, and dairy. Phthalates are used in pesticides and herbicides, neither of which is permitted on certified organic produce. Pesticide-treated animal feeds are not allowed in organic meat and dairy production. Ideally, you’ll eat dairy and meat from grass-fed cows, pigs, and chickens, since phthalates may contaminate animal feed stored in plastic containers (even if that feed is organic).
     
  5. Choose low-fat meat and dairy. I don’t love giving this advice, because I generally am not a fan of low-fat dairy products, always opting for whole milk and full-fat yogurt for my family. Unfortunately, foods that are higher in fat are particularly prone to chemical leaching. Most farms use plastic tubing to milk their cows, which likely introduces phthalates at the start of the production process, and the chemicals then hang out in the fattiest part of the milk. In light of this, you might want to consider buying lower fat cheeses or taking the skin off of chicken.
     
  6. Invest in a water filter. If your water supply is tainted by industrial waste, phthalates may show up in your drinking glass. Granular activated carbon filters should remove DEHP, which is the type of phthalate used in water pipes. A nano-filtration system is more expensive but possibly even more effective way to filter out phthalates.
     
  7. Avoid processed foods. Phthalate contamination is yet another reason to stick to whole foods as much as possible. The more opportunity your food has had to come in contact with plastic throughout the production process, the greater the chance that it will be tainted with phthalates.

Grass-Fed vs. Feedlot Beef - What's the difference?

If asked, most people could not tell you where the meat on their plate came from. In fact, if they wanted to know, it would be darned difficult – if not impossible – to find out. On the other hand, while they may imagine that the beef cow they are eating was once frolicking on lush green pastures, the average American today would NOT want to meet their dinner while it was still standing.

No, Virginia, not all cows eat grass.

That lovely image of a herd of cattle happily munching away and contentedly chewing their cud is mostly a figment of your imagination. Over the last 70 years, the beef industry has evolved into an intense, industrial enterprise designed to put as much weight on animals as fast as possible and get the resulting meat to market as quickly as possible.

To do that, beef cattle – who are by nature ruminants (grass eaters) – are hustled off the pasture where they spent their first six months of life to spend the next six to eight months packed into confined animal feeding operations (CAFOs) with no green pasture in sight. In those feedlots, they are fed grain – lots of grain – to bring them up to the target weight for slaughter. Since it takes as much as 7 pounds of grain (corn, barley, soybeans, and other grain) to develop a pound of meat and those cattle gain about 3 pounds a day, that’s a lot of feed.

At the same time, to keep the cattle gaining weight, they are given growth hormones and antibiotics. According to the Union of Concerned Scientists, 70% of all antibiotics used in the United States are fed to livestock. And, as many as six different growth hormones may be given to beef cattle, three of which occur naturally and three of which are synthetic.

Since those animals are eating 50 to 60 pounds of feed a day, a quick look at the source of that feed is important. Forty-four percent of the corn grown in the US is used for animal feed, and 86% of the corn planted in 2010 was bio-engineered varieties that contained insect- or herbicide-resistant genes (or both). Fifty-nine percent of the soybean harvest is crushed for oil, however the meal left over from the crush is used as animal feed. A whopping 94% of all soybeans grown are genetically engineered to be herbicide tolerant.

Meat and potatoes, please…

Researchers have linked serious health problems such as heart disease, stroke, diabetes, and certain types of cancer to heavy meat consumption. Americans eat more meat than ever before, and most of it is high in saturated fats.

We consume about 67 pounds of beef a year for each person – man, woman, and child. And those animals eat a lot of corn and other grain: most beef cattle are “finished” on grain before slaughter; only a very small percentage is entirely “grass-fed.”

Ah, back to that question – don’t cows eat grass? More and more farmers and ranchers are raising grass-fed beef on a natural diet consisting of fresh grasses, legumes, and other plants and allowing them to roam about.

Many are choosing to follow organic practices in their herd management, which are clearly healthier and more humane for the animals. The good news is that meat from those animals is free of antibiotics, steroids, hormones, pesticides, herbicides and other potentially toxic substances. The bad news is that it can take nearly two years to bring those animals to market on grass.

You Are What You Eat Eats Too


Studies have shown that an animal’s diet can have an impact on the nutritional content of the meat on the consumer’s table. Grass-fed meat has been shown to contain less fat, more beneficial fatty acids, and more vitamins and to be a good source of a variety of nutrients. According to a study published in the Journal of Animal Science in 2009, eating grass-fed beef provides many benefits to consumers.

Grass Fed Beef Benefits to Consumers

  • Lower in total fat
  • Higher in beta-carotene
  • Higher in vitamin E (alpha-tocopherol)
  • Higher in the B-vitamins thiamin and riboflavin
  • Higher in the minerals calcium, magnesium, and potassium
  • Higher in total omega-3s
  • A healthier ratio of omega-6 to omega-3 fatty acids (1.65 vs 4.84)
  • Higher in CLA (cis-9 trans-11), a potential cancer fighter
  • Higher in vaccenic acid (which can be transformed into CLA)
  • Lower in the saturated fats linked with heart disease
Lower Fat – Meat from grass-fed cattle is much lower in fat, and therefore lower in calories. A 6-ounce steak from a grass-finished animal has almost 100 fewer calories than the same sized-piece from a grain-fed animal. If, like the average American, you eat about 67 pounds of beef a year, switch to grass-fed beef and you’ll save nearly 18,000 calories a year.

Omega-3 Fatty Acids – Omega-3 fatty acids are fats that are essential to human health. Sixty percent of the fatty acids in grass is omega-3, which is formed in the chloroplasts of green leaves. Grass-fed cattle can contain as much as two-to-four times more omega-3 fatty acids than grain-fed animals.

At the same time, a high ratio of omega-6 to omega-3 fatty acids has been linked with an increased risk of cancer, cardiovascular disease, allergies, depression, obesity, and autoimmune disorders. A ratio of four to one or lower is considered ideal, Grain-fed beef has a much higher ratio of omega-6 to omega-3 fatty acids than wild game or grass-fed beef. In grass-fed beef the ratio is approximately 2 to 1, while the ratio in grain-fed beef is more than 14 to 1.

More Vitamins – In humans vitamin E is linked with la lower risk of heart disease and cancer. Meat from grass-fed cattle is higher in vitamin E.; as much as four times higher in vitamin E than meat from feedlot cattle.

Rich source of CLA – Meat from grass-fed animals is the richest known source of “conjugated linoleic acid” or CLA. Grass-fed cattle have been found to produce 2 to 5 times more CLA than cattle fed high grain feedlot diets. In laboratory animals, a diet containing even a small amount of CLA greatly reduced cancerous growths.

Shop Local for Grass Fed Meat

Finding grass fed meats in you community is getting much easier than it used to be as more and more small ranches are popping up across the USA. It's now common to find grass fed beef and lamb at local farmers markets. The best value is to buy the cow 'on the hoof' which means that you are buying the whole cow- bones, skin and all. The cow is then processed at a butcher and the individual cuts are delivered individually wrapped and labeled ready for your home freezer.

A growing trend among friends and family is sharing a whole cow (also known as cow-pooling, as in car-pooling). This is much easier for the rancher so he can pass the savings on to you. A 1/4 share of a whole grass fed cow usually results in between 150-250 pounds of finished beef depending on the breed and size of the cow.
