Beef groups slammed recommendations for consumers to increase their protein intake via beans, peas and lentils, calling the proposal “unhinged.” A major battle is brewing over how much red meat Americans should consume — and it has the beef industry seeing red. The United States is preparing next year to update its Dietary Guidelines for Americans, an influential set of recommendations that inform nutrition labels, what food is served in schools and hospitals and the advice that healthcare professionals give patients. Drafted recommendations are set to call for greater intake of plant-based foods while limiting consumption of beef and starchy vegetables like potatoes. The committee of scientists behind the recommendations also proposed moving “meats, poultry, eggs” to the last group listed in the protein-foods category while adding beans, peas and lentils as options.
