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?


Is it normal if my boyfriend's semen is chunky?

1) I tried looking for an answer to my question in the archives, but didn't find one. What I want to know is if it is normal that my boyfriend's semen has clumps (I don't know how else to describe it) in it? The semen has never been clumpy before, but the last time I gave him a blowjob, the semen had a chunky consistency to it. Should I be worried that this may be an STD, or is this kind of thing related to other things, and if so, what are they? Thanks.

2) I just realized a few days ago that my sperm comes out in pieces. For example, they are as thick as small boiled rice pieces... is there a concern to worry?


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!


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.


Is Mirena safe for those who have yet to give birth?

I have recently been advised that my on-going migraines might be caused and/or increased by the use of contraceptives containing estrogen. To that end, I have been recommended to switch to a progesterone-only form of birth control. Which, in turn, basically means I get to choose between Implanon and Mirena (I really can't stand needles, so Depo is out for me!). I am only 23 years old, and have not yet started a family. I do want to have children someday, and am very enticed by the idea of Mirena lasting to the point when I might want to begin trying to get pregnant. However, all of the advertisements for Mirena state that ideal candidates have already had children.

Is Mirena still safe for use in women who have not yet given birth? If so are there any additional side effects to consider in this instance?
