Industry (and private lobbies not directly for profit) elects our government officials, who in turn pander back to industry/lobbies. The foxes watch the foxes and we pay the price. The junk food and grain industries are much more powerful (read: rich) than the cattle farmers, so our government advices us to eat tons of carbohydrate (with no regard to quality), but to eat only 4-9 ounces protein and fats "sparingly".
