Are there health concerns associated with consuming Sucralose (Splenda)?

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?


Is reusing water bottles safe?

I started buying bottled water because it seemed to taste better. As an experiment, I tried refilling the empty bottles with tap water and refrigerating them. And I discovered that what I really liked was drinking chilled water out of the bottle. If no one else is using the bottles, how often do I need to wash the bottles out with soap as opposed to just re-filling them?


Why are my wounds healing more slowly?

I have noticed lately that wounds such as cuts are healing much more slowly than before. I have also noticed that I am scarring more. For example, a tiny hole in my hand has developed a scar that is four times the size of the actual injury, and it is slightly raised. Am I missing something in my diet that is causing this? Or could it be an effect from on-going stress and anxiety? I am a vegetarian with some vegan tendencies, and I take a multi-vitamin every day or so.


How can I find support as a gay student in New York?

I'm an undergraduate student from China. And I'm going to the mathematics department with fellowship. I'm really very happy and eager for my future life in Columbia.

I'm now twenty years, but still have no girlfriends. Why? Because I'm a gay student. Sometimes I really feel very sad about that. You see, I'm also an emotional person and I'm eager for love, but I can't. I'd not prefer to make gay friends on Web sites since many of them are lying and I'm afraid to get AIDS. Since I'm very pure, good looking, and excellent in study, some classmates and schoolmates (male) show great affection to me. But I dare not accept it because I'm AFRAID.

Both my parents are professors, but they are very traditional and could not accept that. At the same time, I do not want to hurt them, so I really don't know what to do. I know New York City have a lot of gay students, and it's also such a "free" metropolitan city, so I'm really very glad, but still mixed feeling.

Here I wanna ask you:

(1) Are there a lot of gay students in Columbia University?

(2) Is there any gay club or activity in CU?

(3) What should I do now?

Thanks so much! I've seen your answer to a lot of questions and feel very excellent. Best wishes!
