Additionally, we typically eat way too much meat rather than consuming the recommended 3-ounce serving size.
A recent nutrition research study continues to add fuel to this debate on meat consumption and weight gain[1]. This new study examined the relationship between protein intake and body mass index and compared animal protein to plant protein intakes in volunteers enrolled in the Belgian National Food Consumption Survey. Eating habits were determined by 24-hour dietary recalls from over 3,000 men and women. In this group of volunteers, animal protein consumption was nearly twice as high as plant protein consumption. Meat and meat products made up the majority of the animal protein consumption, while cereals and cereal products made up the majority of plant protein intake. A look at the relationship between different protein intakes and body mass index revealed:
As animal protein intake increased, body mass index became greater in men.
Also in men, eating greater amounts of animal protein resulted in greater waist sizes.
In men and women, an increasing level of plant protein consumption was linked to both a lower body mass index and a smaller waist size.
This new research study continues to suggest that the consumption of animal protein is linked to an increase in body mass index and waist size, putting individuals at risk for becoming overweight or obese. In contrast, altering our eating habits to include greater amounts of plant proteins might help support a healthier body weight and reduce our risk of becoming overweight. Unfortunately, this study's summary does not indicate whether this analysis was done such that it adjusted for caloric content of these foods, as this could impact the final conclusions. Nonetheless, previous research that did make this adjustment still suggested that red meat consumption was linked to weight gain. Reducing the amount of animal protein we consume or making healthier choices in the animal proteins we choose to consume can be an important part of our fight against obesity. Fortunately, the U.S. Department of Agriculture (USDA) recently announced that the 40 most popular meat products will be required to carry a nutrition facts panel starting January 1, 2012. The nutrition facts panel will include the calories and grams of total fat and saturated fat the product contains and any product that lists a lean percentage statement (e.g. "80% lean") on its label also must list its fat percentage. This information will make it easier for all of us to choose meat products that fit into a healthy diet.
