Are the bacteria that make food smell and taste bad the same ones that make you sick?

Taste and smell are not reliable indicators of food safety. Some bacteria that cause food-borne illness do not have off-flavors associated with them. Clostridium botulinum, for example, produces a tasteless but deadly toxin. One clue that it may be present is a bulging lid on canned food. Any cans with bulging lids should be discarded without opening, and disposed of beyond the reach of children and pets. However, botulinum poisoning is not limited to canned foods. It can occur in other foods stored improperly.

Too Much of a Good Thing?

When the FDA mandated the fortification of grain products with folic acid in 1996, it resulted in a dramatic 40 to 50 percent decrease in the number of babies born with neural tube defects, one of the most common birth defects.

Can eating a high-sodium diet still hurt me even if I don’t have high blood pressure?

Although you are not hypertensive now, there are some reasons why it would be a good idea to start moderating your sodium intake. As we age, our blood pressure tends to rise. This does not happen to everyone, but it does happen to the majority of people.

In addition, as we age, it can become more and more difficult to change food habits. Gradually lowering sodium intake over a few years can make the transition easier. Limited data also suggest that even people with normal blood pressure benefit from a modest reduction in sodium.
