A new study finds that regularly eating red meat increases the likelihood of premature death. A serving is about the size of a deck of playing cards. What do you think? How often do you eat red meat?

Can Less Red Meat = Longer Life?

This really caught my attention. Is it true? I honestly didn't know. So I did some research.

First I pulled up the longevity map of the United States. Clearly the southeastern US and gulf coast states had the shorter life spans, while the midwest and northern plains had the longer lifespans.

Next I went to the USDA website and found "the Midwest consumes the most beef in the United States"

If the longevity map is correct,
If the USDA statement is correct,

Then its NOT true that beef consumption leads to a shorter life.

I should say the red on the map indicates shorter lifespan, while the green indicates longer lifespan.

This map looks like the Harvard longevity study map.

In a nutshell, using data from the Harvard longevity map, compared to data from the UDSA on beef consumption, from a geographic standpoint there is no relationship displayed between beef consumption and shorter lifespan.

If anything the data suggests otherwise, showing better longevity in areas where beef consumption is the highest.

Here is a link to the study:

... The problem is this is an observational study. Observational studies can prove NOTHING. They are good only for forming hypotheses.
CORRELATION DOES NOT IMPLY CAUSATION.

This study takes one variable, amount of red meat in the diet, and concludes that there is an increased risk of cardiovascular disease and cancer. Did they try to isolate any other variables? What about smoking, Body Mass Index, physical activity level, was it 'CAFO' meat (exposed to hormones, antibiotics, pesticides), alcohol/drug consumption, vitamin/supplement use? What amount of their diet was from vegetables and fruits? What about the ethnicity of the subjects? Marital status?
CORRELATION DOES NOT IMPLY CAUSATION.

This study was based on a questionnaire. According to the study this questionnaire
http://riskfactor.cancer.gov/DHQ/forms/files/shared/dhq1.2002.sample.pdf
was filled out once every four years. That is only eight 8! data points over 32 years.
Think about describing your diet over the last 4 years. How much detail could you describe?
CORRELATION DOES NOT IMPLY CAUSATION.

Here are some interesting reads on meat in the diet.

Concerning the study showing red meat causes shorter life span. No doubt the Chick-Fil-A cows are behind it.

I say that jokingly, but in reality there probably was some kind of financial motivation behind it. SOMEBODY funded this study. My guess is a company that sells something that competes with beef.

Again, The USDA website states "The midwest consumes the most beef" and the Harvard longevity map shows the midwest and plains states to have excellent longevity.
