Maine Passes GE Crop Bill to Protect Farmers

(Beyond Pesticides, April 14, 2008) After almost a year and a half of debate on genetically engineered (GE) crops, the Maine Legislature passed a bill last week to protect farmers from genetic trespass. According to Protect Maine Farmers, the bill prevents lawsuits for patent infringement against farmers who unintentionally end up with GE material in their crops; ensures lawsuits that do occur will be held in the state of Maine; and, directs the Department of Agriculture, Food and Rural Resources to develop and implement specific practices, or Best Management Practices, for growing GE crops. One component of the bill that was supported by many Maine farmers but failed would have required all businesses selling GE seeds in Maine to report their annual sales data to the Maine Commissioner of Agriculture.

“Maine’s farmers now have some substantial assurance that if they save seed that has been contaminated by [GE] varieties, they are not at risk for a lawsuit,” states Logan Perkins, the lead organizer for Protect Maine Farmers. “Hopefully, the development of these Best Management Practices will give farmers the information they need to make good decisions about how to protect themselves, their livelihoods and their neighbors when using [GE] crops.” North Dakota, South Dakota and Indiana have already passed similar legislation.

How Can I Get Enough Protein? The Protein Myth

The Building Blocks of Life

Protein is an important nutrient required for the building, maintenance, and repair of tissues in the body. Amino acids, the building blocks of protein, can be synthesized by the body or ingested from food. There are 20 different amino acids in the food we eat, but our body can only make 11 of them. The 9 essential amino acids, which cannot be produced by the body, must be obtained from the diet. A variety of grains, legumes, and vegetables can also provide all of the essential amino acids our bodies require. It was once thought that various plant foods had to be eaten together to get their full protein value, otherwise known as protein combining or protein complementing. We now know that intentional combining is not necessary to obtain all of the essential amino acids.1 As long as the diet contains a variety of grains, legumes, and vegetables, protein needs are easily met.

Protein Requirements

With the traditional Western diet, the average American consumes about double the protein her or his body needs. Additionally, the main sources of protein consumed tend to be animal products, which are also high in fat and saturated fat. Most individuals are surprised to learn that protein needs are actually much less than what they have been consuming. The Recommended Dietary Allowance (RDA) for protein for the average, sedentary adult is only 0.8 grams per kilogram of body weight.2

To find out your average individual need, simply perform the following calculation:

Body weight (in pounds) X 0.36 = recommended protein intake

However, even this value has a large margin of safety, and the body’s true need is even lower for most people. Protein needs are increased for women who are pregnant or breastfeeding. In addition, needs are also higher for very active persons. As these groups require additional calories, increased protein needs can easily be met through larger intake of food consumed daily. Extra serving of legumes, tofu, meat substitutes, or other high protein sources can help meet needs that go beyond the current RDA.

The Problems with High-Protein Diets

High-protein diets for weight loss, disease prevention, and enhanced athletic performance have been greatly publicized over recent years. However, these diets are supported by little scientific research.
