Does a snack at half-time boost energy to finish a sports game?

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?


Should I tell my current partner if my ex just told me they have an STI?

I've been going out with a girl here at my school for the past six months. Last weekend I went home (out of state), and fooled around with an ex-girlfriend. She called me last night and told me that she might have an STI. She went to the doctor this week and told me she would let me know when she finds out for sure. We didn't use a condom.

My problem is, what should I tell my girlfriend? I really love her and don't want to ruin things because of this stupid fling I had. But I can tell she's annoyed that I've avoided her all weekend. I can't exactly tell her next time we get together that I don't feel like fooling around, but I don't know how long it will be before I know if I'm infected. And what do I do if I am? Help!


Is it safe to chew and spit out food?

I have been chewing and spitting large amounts of food (pretty much always sweet stuff — pastries, chocolate, etc.) almost every night for eight or nine months. I am eating a healthy, balanced diet otherwise, maybe a little on the lower caloric side (1300 to 1500 calories per day). My chewing and spitting sessions usually follow a balanced meal. I know this is a type of eating disorder. I have done a lot of research online and I know that there are side effects, although they vary depending on who you ask. Some sites mention that chewing and spitting activates the release of insulin and results in hyperinsulinemia, insulin resistance and weight gain. Is this true? How long would it take to develop these problems? Are these reversible if I were to stop this behavior?


What can I do if my parents don't believe I'm bi?

I came out recently to my parents as being bisexual. They were surprised, as expected, but they didn't believe me! They said it's "not normal for someone to suddenly change their orientation." But it wasn't sudden — I've known for a while! What should I tell them?


How should I tell my partner about my herpes?

When my boyfriend and I began our sexual relationship, he insisted on using condoms. I gratefully agreed because I felt it then wouldn't be necessary for me to tell him about my STD — herpes. Now, two months later he's decided that he "trusts" me enough to stop using the condoms. I don't see any way I can keep the relationship, even if he can handle the STD part, if I tell him I've been lying over the past two months. Do you have any advice? I don't want to lose him, but I don't want to be responsible for giving him any diseases either.


How to read and trust nutrient value charts?

I have researched health and nutrition online for a while now, and I work out not only with weights and yoga, but martial arts and mountain biking, as well.

Lately while researching online, I've found that a lot of nutritional value charts conflict in numbers. Some charts say that skim milk contains eight grams of protein, some charts say skim milk contains 13 grams of protein. Which charts are right?? This is incredibly frustrating and confusing. I did find out that there is nutrition software available, but it's so expensive and it comes with lots of extra things that only doctors need really, like making charts for patients and what not.

Also, I found information on one site saying that adults should consume 0.8 grams of protein per however many kilos you weigh (I weigh 82 kilos, so that means 66 grams of proteins per day). Another site said that adult females between 25 to 50 kilos just need 55 grams of proteins per day. Also, it's not just protein intake that conflicts with all of these charts online.

If you can help out at all, it would be greatly appreciated. Thank you in advance.


Am I ready to start dating a new guy?

I have recently started seeing this man who I think is adorable and things are going really well. My last relationship was a three year nightmare that ended a long time before I finally broke it off. Everyone keeps saying to follow the rules and take it slow and to be careful because I am on the rebound and it is too soon to get involved. How can I know if what I am feeling is right and if I should just go with the flow? I am still feeling so new at all this stuff and I am often very scared to get hurt again. Please give me some of your expert advice!


How can I help loved ones who have bulimia?

1) I've recently just found out that my boyfriend of four years is bulimic... He hasn't told me, but I have put the puzzle pieces together after living with him for the past 18 months... I had even heard him purging in the bathroom while we were on vacation. I'm really struggling with this information and I don't know how to approach him about it... I'm guessing it has been going on for around six years now. How do I confront him about it??

2) I was wondering if bulimics lose weight rapidly, because I have a friend who I think may be bulimic, because she eats, but I think she may be throwing up her food. She has lost 25 pounds in the last month. She binges, and I would like to know how I can help her.


Are waxy fruits safe to eat?

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?
