The safest choice for food storage is glass. A couple of years ago, glass food storage containers were hard to come by and expensive. Look for brands that are made in the United States because some glass imported from China has been shown to contain lead or cadmium especially if there is paint or enamel involved.
Two brands that are made in the U. Duralex is made in France and Lifefactory is made in Europe, so they should also be safe. Both Ball and Kerr canning jars are made in the U. You can check your existing glass for lead with LeadCheck Swabs. There has been a lot of talk about what plastic is safe to reuse, and what is not. First of all, there are different sorts of plastic, used for different purposes.
They are categorized in accordance with what raw material was used to produce the product. Here are the different categories:. According to The Green Guide , a website and magazine focusing on promoting greener living and owned by the National Geographic Society, the safest plastics for repeated use in storing food are from categories 2, 4 and 5. Most Tupperware containers are made from 4 or 5 plastics. However, some of their products are made from polycarbonate, 7, which has been shown to leak the harmful, hormone-disrupting chemical Bisphenol A BPA into food items after repeated use.
Bisphenol A BPA. So what is BPA really, and how harmful is it? Bisphenol A is a key industrial chemical used to make polycarbonate, which is a hard, clear plastic. Studies made by governments in the US, Europe and Japan, as well as studies conducted by academic researchers and by industry, show that under typical use conditions, the migration of BPA into food is extremely low. In my opinion, there is more reason to worry about some of those other categories, like 1 and 3.
Not many I guess. Most of us use these bottles more than once. This will stop NOW. I took a look at the water bottles in the store last time I was there, and turns out almost every single one of them was made out of 1 plastic.
Bottles made from this plastic are proven to leak carcinogenic, hormone-disrupting phthalates when used over and over again. PVC can leak cancer-causing dioxins , which is one of the most toxic environmental pollutant there is. PVC is found in a wide range of consumer products, such as packaging, credit cards, bottles and imitation leather, as well as in construction material, such as window frames, cables, pipes, window blinds, wallpaper and flooring.
In addition to that it is used in car interiors and in hospitals, as medical disposables. Burning creates and releases more dioxins and compounds containing chlorine, which further contaminates the environment. Furthermore, phthalates are present in this category as well. They are added to PVC to make it soft and flexible.
Have you started using more glass storage containers in response to the news reports about PVC, polystyrene, and bisphenal A or are you just more careful in selecting plastic ware?

She believes it is possible to live fully and eat well while spending less. I would like to know what PP Grade was used in Tupperware products? As I only can see PP material engrave on the product. Good point. I buy cook mostly from scratch, but when I do buy packaged ingredients I try to buy them in glass jars.
Pyrex, for instance, does not contain chemicals that can leach into food. Of course, such items can break into glass shards if dropped. But most consumers would gladly trade the risk of chemical contamination for the risk of breakage any day. Read past columns at: www. We can't go back in time, but some things have definitely changed.
There's surprisingly little research on how our bodies actually build muscle.
