Should I tell my friend that I'm worried about how she sleeps around?

My friend has only been at college for two weeks, and she has already had sex with several guys. She is having safe sex, so it's not dangerous in that sense and she claims to be enjoying herself. However, it seems to me that such behavior is unhealthy and damaging to one's emotional state and reputation — but I'm not sure how to explain to her how I feel, or articulate what is wrong with her how she's acting. Do you think what she's doing is wrong, and if so, how should I confront her?


Are there different nutrient and energy requirements for endurance versus resistance athletes?

I am a second year Nutrition student and have a question about protein and endurance athletes. Why are their protein requirements greater than they are for resistance athletes? Is it because the muscle glycogen stores get depleted over a long period of time with intense exercise? If so, should they consume more carbohydrates than resistance athletes, with a low glycemic index prior to their workout?


Is it okay to replace cravings or "boredom eating" with herbal teas?

I am currently trying to revise my eating habits to eat less often (I'm a throughout the day snacker, and normally don't eat meals). Is it okay to replace cravings or "boredom eating" with herbal teas? I was told that tea is a no calorie drink, and yet it fills me up when I'm hungry. I have started to replace most of my cravings with tea now, so that I actually eat a lot less than before. Is tea healthy for you if it is no caffeine, herbal, and I use honey to sweeten it? I am not used to drinking much of anything in the day and am fairly slim, so could the extra water intake have any weight gaining effects on me? Could this be a healthy diet?


How can I get over the awkwardness after telling my friend I like him?

I'm very attracted to one of my close friends. He used to like me and I used to like him. The other day, I told him I still liked him and that it'd be cool if we took our friendship further. But he just said he liked me as a friend. However, many of my friends have been telling me that he likes me more than a friend and that we'd be good together. After telling him how I feel, I think that he doesn't even want to be friends now, plus he is really awkward. How can I get our friendship back and break the awkwardness? How can I make sure I don't get rejected again by someone else?


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?


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.


Are grains and vegetables sources of protein?

I know that plants (besides soy) are considered "incomplete" protein sources, because they don't contain all of the essential amino acids. However, why is it that the nutrition facts of many grains and vegetables say they have protein? For example — a serving of pasta has seven grams of protein, corn has twp grams, and chickpeas have six grams. Is this considered "incomplete" or "complete" protein, and how can you know how much complete protein you are eating when you mix, for example, a serving of corn, and beans? I think average people should eat 50 to 60 grams of protein a day, but how can you ever know how much you are really eating if you are mixing incomplete proteins that together contribute to your day's protein requirement?
