Is there a better subject with which to begin a discussion of the relationship between food and health than apples? After all, doesn’t “an apple a day keep the doctor away”? Maybe it does, if you throw it at her! There are no single foods that have magical health properties. There are good diets and there are bad diets. It is certainly possible to have a good diet and never eat apples, just as it is possible to gorge on apples and have a horrible diet. What really matters in terms of nutrition is the net effect produced by all of the chemicals that wend their way into our bodies from the food we eat. Yes, chemicals. I can practically see those eyebrows being raised. It may seem unusual to see the word “chemical” without an adjective like “poisonous,” in front of it. Actually, without appropriate context, “toxic chemical” is a meaningless term. . . . Everything in the world is made of chemicals, and if you restricted yourself to a diet free of chemicals, you would be dining in a vacuum! With that in mind, let’s investigate the chemicals in an apple. So tell me, would you like some nail polish remover in your diet? Or rubbing alcohol? Then have an apple! Yes, all apples contain acetone and isopropanol. And if these don’t sound toxic enough, you can throw in some cyanide. It’s there too. Added by nature, not by humans! Should you then be worried about eating apples? Of course not! The amounts of these chemicals are too small to be of any consequence. Apples, as already mentioned, contain over 300 naturally occurring compounds, and whatever effect the fruit has on our health is a reflection of all of these.
