Bisphenol-A (BPA) is a chemical found in the plastic containers of many common foods and beverages. The main food sources are bottled water, packaged foods and canned items, such as fish, chicken, beans and vegetables. Regarding BPA’s negative effects, studies have shown that BPA can dissolve out of these containers and into the food or beverage, making these foods the biggest contributor to high BPA levels in the body.
While a 2010 study found BPA in 63 of 105 samples of food, studies on pregnant animals have also shown that BPA exposure could result in reproductive problems, increased risk of breast and prostate cancer in developing fetuses, infertility, insulin resistance, type 2 diabetes, and obesity among others.
Results from one study, for example, suggest a connection between high BPA levels and polycystic ovarian syndrome (PCOS), a disorder of insulin resistance characterized by elevated levels of androgens, which are hormones crucial for reproductive function such as testosterone. Furthermore, research has also linked high BPA levels to altered thyroid hormone production and function. This is attributed to the chemical binding to thyroid hormone receptors, which is similar to its interaction with estrogen receptors.
While 40 independent studies have reported that negative effects have occurred at levels below the recommended limit in animals, you can reduce your BPA exposure within the recommended daily limit (23 mcg/lb of body weight) and avoid future health risks by looking for BPA-free bottles and containers, as well as by eating mostly whole, unprocessed foods.
https://poppylifecare.org/nutrition/Most types of fish are extremely healthy. But certain species contain high levels of mercury, a neurotoxin that damages the brain and nerves, and which pregnant women are at particularly high risk, since mercury can affect the fetus’s developing brain and nervous system.
A 2014 analysis found that in several countries, mercury levels in the hair and blood of women and children were significantly higher than the World Health Organization recommends, particularly in coastal communities and near mines. While another study found that the amount of mercury varied widely among different brands and types of canned tuna, it found that 55% of the samples were in excess of the EPA’s 0.5 ppm (parts per million) safety limit.
Analyzing that data, it’s not difficult to see how seafood consumption is the largest contributor to mercury accumulation in humans, which comes as a result of this chemical working its way up the food chain in the sea, where plants that grow in mercury-contaminated waters are consumed by small fish, which are then consumed by larger fish. Over time, mercury accumulates in their bodies, which are eventually eaten by humans.
While eating other types of fish is still advised because of their nutritional benefits, you should limit your mercury exposure by avoiding fish with extremely high mercury content such as king mackerel and swordfish. Instead, choose seafood from the “lowest mercury” category on this list and take advantage of the fact that it includes most of the healthy fish, highest in omega-3 fats, too.
As a final note, remember that I’ve mentioned only a few of the toxins found in your daily food products, and it does not mean that you will have to stop eating these completely. In the case of fish, which provides great sources of nutrition, you could improve your selection and eat in moderation, for example. It is also important to know that if you have a diet high in toxins, you can find balance with exercise, healthy fruits and vegetables, which will detoxify your body and maintain a nutritional balance.
