If ever there is one universal language, it would definitely be food. As the years go by, we try to understand and reconcile ourselves with the power of food over our lives. They could make us young or old, fat or slim, health or weak. Because of this, a lot of studies and discoveries were made on the topic of food.

As well look at us in the mirror, most of us would almost immediately notice those lines in our faces. Suddenly we all wonder if we are too old or the environment around us is simply moving time so fast. We wonder what could be done.

When we got up and stepped on that scale, we are shocked to see that line hit past the average weight. We panic as we think that we are getting fat and would mean getting slow. Mentally we relate our weight to our heavy bodies and low energy. We almost immediately sign up for that gym class.

We are extremely conscious of what we look that we tend to forgot that sometimes the answer could be that simple. In our society today, we are bombarded with pollutions and fast food. These two have a tremendous effect on how we eat and look. Fast food centres offer unhealthy food that often times contribute a lot of problems.

Lots of studies and experiments are being done to answer our cry for help. We want a diet that is effective. A diet that could boost our energy levels, make us feel young, look young, affordable and sustainable.

One interesting and very realistic discovery is "food combining". Correctly combining foods makes all the difference in the world to proper digestion, cholesterol and metabolism. Without complete digestion, the nutrients in even the most wholesome food cannot be fully extracted and assimilated by the body.

Before we could even say or open our mouth about food combining, we must first be equipped with the basic knowledge about food, its classifications and digestion. We cannot disregard these as they are the fundamental stones of which this was based. Thus in this book we are going to fully explore the concept of food combining.
