A new study in the Journal of
Alzheimer’s Disease finds a strong
link between some food preservatives
and an increased risk of death from
Alzheimer’s, Parkinson’s and diabetes.

Nitrates and nitrites are found in a lot of foods we eat: bacon, hot dogs, and even cheese and beer.

The chemicals aren’t there naturally – they’re added as preservatives. And they’re also used in fertilizers.

Dr. Suzanne de la Monte is the study’s lead author.

She says they found a strong connection between higher death rates from Alzheimer’s, Parkinson’s and diabetes and the increases in our exposures to these chemicals in our food and water since the late 1960s.

“What we’ve identified says this is certainly something I would consider very very important. Are there other things? Probably.”

She says people could be genetically predisposed to these diseases.

But she says long term exposure to nitrates and nitrites could also be playing a role in two ways: whether we get these diseases and how severe they might end up being.

Curbing Cow Burps

Cows burp methane gas. It’s a potent greenhouse gas. The Environmental Protection Agency says cow burps alone make up 20% of the methane emissions in the US. Rebecca Williams reports some people worry the government might step in:

The farm lobby’s worried Congress will try to regulate gassy cows.

But if you thumb through the giant climate change bill before Congress, you’ll find Section 811. That section says the government can’t regulate cow burps.

In the meantime, some farmers are trying to make their cows less gassy.

The company Stonyfield Farm is getting its dairy farmers to change their cows’ diets.

Nancy Hirschberg is with the company. She says the new diet has cut cow burps by 12%.

“It’s very much like people. When you are feeling good, you’re not having a lot of gas – you’re more efficient, more of your energy is available for living life. The same with the cows, you want as much energy as possible to go into producing milk, not into burps which are in fact, waste.”

She says the cows also have sweeter breath.
