Bisphenol A (BPA) is a chemical found in the inner coating of cans and in some plastic bottles. Some studies find higher blood levels of BPA in people who have cardiovascular disease. Now a study has tested whether BPA can raise blood pressure.
Korean scientists gave soy milk to 60 people aged 60 or older on three occasions. The beverage was served in either cans or glass bottles (glass is BPA-free).
Two hours after drinking the beverage from either kind of container, systolic blood pressure had dropped (possibly because of the soy milk). But it fell 5 points less after the participants drank the soy milk from the cans than after they drank it from the glass bottles.
What to do: Try to buy foods in glass bottles or cartons rather than cans. This study doesn’t prove that BPA causes high blood pressure over the long term, but why not play it safe? Also, the National Institute of Environmental Health Sciences has ex¬pressed concern about BPA’s “effects on the brain, behavior, and prostate gland in fetuses, infants, and children.”
