For starters... more families (that have access to large quantities of meat) need to do at least one meal a week without it.... then grow to two+.
Also, meat per meal is WAY too high! Most men should have 6 ounces of meat or less, but have more, 2 to 3 times more. Women, 2-3 ounces!
Meat, the right meat can be so beneficial but the body can only absorb so much. We consume meat and bread in much larger quantities then vegetables. This is a fatal mistake.
Besides meat consumption being way to high to be healthy, overall consumption is mostly from over processed foods that contain little value and cause weight gain. People eat in sporadic intervals and then eat mostly empty calories. Dead foods instead of 'live' ones.
Food education through media and schools is the fastest way to solve this but teachers are inundated with testing. Jamie Oliver's Food Revolution is a great start. Harvest Foods program from a few years ago put fresh vegetables into the hands of elementary school children. It came with curriculum and a poster too. School gardens are great too. Ours is a lot of fun and educational.
