Blog: Can one change improve your health and the world's?
By Jennifer Nelson, M.S., R.D. and Katherine Zeratsky, R.D.
Eating too much red meat and saturated fat has been shown in numerous studies to be associated with adverse health effects, such as elevations in total and low-density cholesterol levels, and increased risk for heart attack and stroke. Red meat is also a source of several cancer-causing compounds, including those formed when meat is cooked at high temperatures, and saturated fat, which is associated with increased risk of breast and colorectal cancer.
A study of meat consumption among over 500,000 Americans, published in the "Archives of Internal Medicine," found that those who ate the most red meat (about 6 ounces daily) had the highest death rate from all causes, as well as a higher risk of cancer and heart disease, than those who ate the least amount (about 1 ounce daily). The researchers calculated that 11 percent of deaths in men and 16 percent of deaths in women could be prevented if people decreased their red meat consumption to the level in the lowest intake group.
An accompanying editorial takes a more global view and points out that reducing meat consumption could improve "world health" — meaning, in this case, the health of the planet. And the United Nations has urged countries to find ways to reduce the livestock industry's impact on the environment:
- Water supply. The amount of water used to raise animals for human consumption is two to five times the amount needed to cultivate basic food crops. In addition, livestock production contributes to erosion and contamination of the water supply with antibiotics, pesticides, nitrogen and phosphorus.
- Climate. Livestock are responsible for about 18 percent of greenhouse gas emissions — more than what is created by transportation. Deforestation to make room for pastures and feed crops also contributes to the greenhouse effect.
- Biodiversity. Livestock and wildlife interact in many ways — both positive and negative. Livestock can help sustain open grassland ecosystems. However, expansion of grazing land and feed crops into forested areas has resulted in the irreversible loss of native plant and animal species.
I want to point out that there are major efforts underway on the part of those who raise livestock to minimize these impacts. I applaud these efforts. We need to do our part too. Cutting down on meat consumption can result in better personal health — and perhaps a healthier world too.
