I missed a tuna-fish sandwich with mayo on toasted wheat bread more than anything. Six months after I went vegan, I snuck into a deli and took one home. And, of course, it wasn't nearly as good as I fantasized. It tasted, well, fishy.

We've all seen chicken portrayed as the low-fat, heart-healthy alternative to red meat for years, but it no longer adds up. You might want to lean away from eating birds and lean toward more plant-based options of protein like black beans, lentils, tofu, chickpeas and whole grains.

Personally, I like to juice up several different kinds of fruit and vegetables - which may include various combinations of bananas, red bell peppers, apples, carrots, celery, broccoli, spinach, parsley, tomatoes, cucumbers, etc.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.
