Food Combining question

I noticed several weeks ago the little note about having melons by themselves because the rules of food combining state that melons are best eaten alone. How much do you subscribe to the rules of food combining? Is there a good resource you can recommend for finding the right information about food combining?

I'm only asking because I find I need to alter the menus a little to feel my best. I need a little more protein and sometimes I look at a meal and say, I just can't do that. So I'd like to learn more about the principles behind the menu so that I can make wise choices when I have to deviate.

For example, I notice you don't include meat with bean meals. Is that because beans are too starchy to combine with protein? Or what's the reason? (I'm thinking of my favorite food--chili with meat and beans. Is that a no-no?)

When I looked into food combining, I noticed things like, only one protein with a meal. No eggs and meat at the same meal, for example. Or no dairy with a meal that contains any other protein. And they say to have only one protein meal each day. This goes against what Enlita says--some protein with each meal and snack.

Plus, beans are listed as both a protein and a starch. I only want to learn good principles, and instead, I'm confusing myself.

Can you help clear it up a bit?
