Interesting Medical Study on Omnivores versus Vegetarians

The link to the actual study

An excerpt:

Population-based studies have consistently shown that our diet has an influence on health. Therefore, the aim of our study was to analyze differences between different dietary habit groups in terms of health-related variables. The sample used for this cross-sectional study was taken from the Austrian Health Interview Survey AT-HIS 2006/07. In a first step, subjects were matched according to their age, sex, and socioeconomic status (SES). After matching, the total number of subjects included in the analysis was 1320 (N=330 for each form of diet – vegetarian, carnivorous diet rich in fruits and vegetables, carnivorous diet less rich in meat, and carnivorous diet rich in meat). Analyses of variance were conducted controlling for lifestyle factors in the following domains: health (self-assessed health, impairment, number of chronic conditions, vascular risk), health care (medical treatment, vaccinations, preventive check-ups), and quality of life. In addition, differences concerning the presence of 18 chronic conditions were analyzed by means of Chi-square tests. Overall, 76.4% of all subjects were female. 40.0% of the individuals were younger than 30 years, 35.4% between 30 and 49 years, and 24.0% older than 50 years. 30.3% of the subjects had a low SES, 48.8% a middle one, and 20.9% had a high SES. Our results revealed that a vegetarian diet is related to a lower BMI and less frequent alcohol consumption. Moreover, our results showed that a vegetarian diet is associated with poorer health (higher incidences of cancer, allergies, and mental health disorders), a higher need for health care, and poorer quality of life. Therefore, public health programs are needed in order to reduce the health risk due to nutritional factors.

This is interesting for a lot of reasons. Yes, vegetarians are skinnier in general and don't destroy their livers as much but...that's it. They tend to have higher cancer rates (probably because our bodies were built to eat fish and meat) and allergies (dear God, like I would need anymore! Meat and potatoes please after Lent. For right now, Salmon and rice, please!). What I find interesting though is the mental health disorders part. Possibly due to not getting certain proteins needed to make various chemicals in the body? I'm not sure.

At any rate, the study is an interesting read and does prove one thing, being fat and happy isn't necessarily a bad thing. ;-)
