I get the apples provided in the dining hall on campus every day and have noticed that they are completely coated with wax (scratching the surface produces white flakes). I was wondering, how harmful is the wax if I eat two or three apples a day?

I was told to eat foods with pectin. All I know is that apples have pectin. Do any other foods contain pectin?

My soccer coach is suggesting we eat bananas at half-time of our soccer game to rebuild our energy for the second half. I understand that bananas are a very good source of energy, among other things. I don't see any detriment to this idea, but my question is this: Does the consumption of bananas result in an immediate energy boost? I have always been led to believe that food must be digested through the system before the body realizes the benefits, and that usually takes several hours. Can you enlighten me?

1) What are your thoughts regarding the use of Splenda as a sugar substitute? I have heard that the body is not able to metabolize this and that it is excreted through the urine. Do you have any current research on Splenda and the side effects? I realize it is a relatively new product. Thank you!

2) I searched the archives and found no information on Splenda or sucralose. Lately, it seems like Splenda is gaining popularity in the crowded sugar-substitute category. It seems too good to be true — measures cup for cup like sugar, you can bake with it and mix it into drinks, and it is made from sugar so it really tastes like sugar. My two questions are... is this a safe product, or are there some disadvantages with the product? And secondly, if it is very safe and versatile, why aren't more companies using it now?

I know how important it is to get plenty of fruits and vegetables in one's diet, but I've been finding it difficult ever since I moved out to do so. I live by myself, on a fixed income, and I can only grocery shop once a week. Whenever I buy fruits and vegetables, they end up going bad three or four days after I buy them, and I feel like I've wasted them. Do you have any advice on cheap, vitamin-rich fruits or vegetables that keep for a good long time? Thanks!

Despite medication, diet control, and exercise, I still have a ratio problem regarding HDL/LDL. What foods would you suggest to boost HDL, while reducing LDL?
