Water bottles: the safest choices.
How safe is BPA-free plastic?
Do you rest easy using BPA-free plastic containers? Many people do. But we may be trading a frying pan for a fire…or at least another frying pan. After research pointed to potential health harms from the chemical bisphenol-A (BPA) leaching from hard-plastic containers and packaging into foods, many manufacturers switched to a different chemical, bisphenol S (BPS), and started labelling their products “BPA-free.” As it turns out, BPS may carry health risks, too. Studies have shown that BPS, like BPA, may have hormone-like effects in the body and harm the heart. In a recent study in mice, BPS was shown to worsen heart function within minutes of exposure, leading researchers to consider that BPS may be more harmful than BPA, particularly for people with heart disease. More research is needed, but if you want to play it safe, use glass, porcelain, or stainless steel containers for food and beverage storage whenever possible. Minimize your use of canned goods, too, since many are lined with materials that include BPA or BPS. Avoid putting plastic containers in the microwave, or putting hot foods or drinks in them, as heat can break down the plastic and increase leaching. And wash your hands after handling receipts from cash registers, since many are coated with BPA—or better yet, choose an email or text receipt when you can.
