6 Potentially Harmful Substances in Food: What You Need to Know
6 ‘Toxins’ in Food That Are Actually Concerning
We often come across alarming claims about everyday foods containing dangerous toxins. Thankfully, many of these warnings don’t hold up to scientific scrutiny. However, there are a few ingredients that might be harmful if consumed in large amounts. Curious about which ones? Let’s break them down in simple terms and offer some real-life tips along the way.
1. Bisphenol A (BPA) and Its Cousins
BPA used to be common in plastic containers and can linings, meaning it could seep into your food. It’s known to mimic estrogen, potentially messing with hormone signals. Animal studies even suggest that BPA exposure during pregnancy might lead to reproductive issues and higher future cancer risks. While many products are now BPA-free, similar compounds like bisphenol S (BPS) have taken its place and may carry comparable risks.
Practical tip: Instead of relying on plastic dishware or bottled water, consider switching to glass or stainless steel. Have you ever wondered why some cans now advertise BPA-free packaging?
Summary: BPA, once prevalent in packaging, has been mostly phased out due to health concerns, but its replacements might not be much safer.
2. Artificial Trans Fats
Trans fats are produced by chemically altering unsaturated oils, often found in processed snacks, baked goods, and margarine. They’ve been proven in multiple studies to spur inflammation and harm heart health. Because of these risks, the United States banned artificial trans fats in 2020.
Think about your favorite packaged snack – if it lists trans fats in the ingredients, it might be worth reconsidering. The good news is that natural trans fats in some animal products don’t seem to have the same adverse effects.
Summary: Artificial trans fats are linked to inflammation and heart disease, which is why they’re now banned in the U.S.
3. Polycyclic Aromatic Hydrocarbons (PAHs)
PAHs are chemicals formed when organic matter burns. They’re notably present in smoked or grilled meats when fat drips and burns, but you might also find them in processed foods. Studies have shown that PAHs can raise the risk of various cancers, including breast and colon cancer.
To cut down on these compounds, try methods like braising or slow cooking instead of charring your food. Have you noticed less smoky flavors when you switch up your cooking style?
Summary: High levels of PAHs in grilled and smoked foods can increase cancer risk—so altering your cooking methods might be a healthier choice.
4. Coumarin in Cassia Cinnamon
Not all cinnamon is created equal. The common cassia varieties (C. cassia, C. loureiroi, C. burmannii) contain coumarin, a substance that might lead to liver damage and even cancer if consumed in high amounts. This is particularly concerning for those who sprinkle cinnamon regularly on their meals.
A handy tip: Look for Ceylon cinnamon, also known as “true cinnamon”—it’s pricier and a bit less common, but it contains much less coumarin.
Summary: While cassia cinnamon is popular, its coumarin content can pose health risks; switching to Ceylon cinnamon could be a safer option.
5. Added Sugars
Added sugars, especially those high in fructose like high-fructose corn syrup, do more than add calories—they’re linked to obesity, type 2 diabetes, liver disease, and even cancer. Often found in sugary drinks and processed snacks, these sugars can trigger addictive eating habits by releasing dopamine in the brain.
What’s a simple change? Try reducing soda and packaged dessert consumption. Experiment with natural sweeteners or whole fruits instead!
Summary: Added sugars pose several health risks and should be enjoyed only occasionally rather than as a daily staple.
6. Mercury in Fish
Fish offers many health benefits, but certain types, especially large deep-sea species, may contain high levels of mercury—a neurotoxin. Mercury accumulates in larger fish as it moves up the food chain, and exposure can be particularly harmful to children, pregnant women, and breastfeeding mothers.
A tip to keep in mind: Opt for low-mercury fish like salmon, pollock, herring, or catfish rather than king mackerel or swordfish. Have you checked which fish you usually pick at the market?
Summary: While fish is nutritious, choosing low-mercury options can shield you from potential neurological risks.
The Bottom Line
Although many scares about food toxins lack scientific backing, some ingredients do warrant caution—especially when consumed in large quantities. The key is moderation. Instead of completely cutting out these foods, consider limiting them. For instance, reducing processed foods and added sugars can make a significant health difference.
Just one thought: Is there a processed food in your daily routine that you could easily swap for a whole-food alternative? Perhaps start with breakfast—try a homemade scramble instead of a frozen meal for a healthier kickstart to your day.
