查罐装食品涂层的时候,偶尔看到的
在美国92%的罐装食品/饮料有BPA隐患(可信与否自己判断)
http://health.howstuffworks.com/wellness/food-nutrition/facts/92-percent-of-canned-goods-contain-bisphenol-a.htm
大致总结一下:
尽量不要金属罐装食品(其实纸盒包装的也有BPA)
玻璃罐头,玻璃瓶饮料要安全很多
干的豆类干果也很好
使用玻璃和不锈钢的餐具,水具
尽量避免加热或者微波塑料包装食品

10 ways to reduce exposure to BPA
If you're concerned about exposure to bisphenol-A, there are several easy ways to avoid it.
At the store
• Reduce your use of canned foods, or look for cans that are clearly marked BPA-free. Or purchase food in aseptic "brick" cartons.
• Use fresh or frozen vegetables and fruit, which haven't been exposed to BPA.
• Use dried beans instead of canned. They may take longer to cook, but you'll save tons of money.
• Buy tomato sauces in glass jars. BPA may be present in the lining of the jar lids, but exposure is limited if they have been stored upright.
• If you drink juice or soda, opt for glass or plastic bottles, which are safer than canned versions, which often contain BPA.
At home
• Don't microwave food -- including frozen entrees -- in plastic containers. Polycarbonate plastics may be durable, but they can break down at high temperatures, increasing the possibility of BPA leaching into food. Instead, use glass or ceramic dishes for microwaving food.
• As a general rule, try to store food in glass containers. If you use plastic food containers to store food, avoid using them for acidic foods.
• Wash plastic containers by hand in warm, soapy water. High temperatures in dishwashers can also cause plastics to break down.
• For portable water bottles, opt for BPA-free stainless steel, though most new recyclable plastic water bottles do not contain BPA. Plastic bottles that contain BPA are usually marked with a No. 7 recycling code on the bottom.
• Avoid using old and scratched plastic food containers and bottles.
