Diabetes risk increases with higher intake of total protein and animal protein, according to a new study in this month’s issue of Diabetes Care. Researchers analyzed the diets of 38,094 Dutch participants from the European Prospective Investigation into Cancer and Nutrition (EPIC) study and found that for every 5 percent of calories consumed from protein instead of carbohydrate or fat, the risk of developing diabetes increased 30 percent. Increased animal protein intake coincided with increased intakes of saturated fat, cholesterol, and heme iron, and with increased body mass index, waist circumference, and blood pressure. Vegetable protein intake was not associated with diabetes risk.

Bacteria from chicken products may be a major cause of urinary tract infections, according to a new study published by the Centers for Disease Control and Prevention. Researchers examined urine samples from women who had urinary tract infections and matched E. coli in the samples to E. coli from contaminated foods. They found that most of the E. coli was ingested through retail meat products (61 percent of which were chicken products) and ready-to-eat products (73 percent of which were meat products). The authors concluded that chicken was the main source of urinary tract infection-causing E. coli. Researchers also warned that animal product sources of E. coli might be drug-resistant which can require more costly and complicated treatments.
