Some of the facts that jumped out at me were the changes in the quantities of food we eat. For instance, did you know that in the last 100 years, meat intake has risen from about 124 pounds per person per year to over 200 pounds. Cheese consumption was less than 4 pounds a year; now it is 33 pounds! He also points out that we've been sold a bill of goods on chicken. He says that "chicken's fat content isn't much different from beef's (about 29 percent for lean beef, 23 percent for skinless chicken breast)."
Now that you know some of the ways our eating habits have changed, I encourage you, if you're a meat eater, to cut back on the amount of meat in your diet. One of the nutrition courses I'm taking pointed out that if you get most of your protein from meat, you only need - at most - a palm-sized portion once a day. You might also look at your plate size. About 100 years ago, a typical dinner plate was 9 inches; now they're about 12. By decreasing the size of your plate, you can trick your mind into feeling fuller since it gives the illusion of more food.
