Are there concerns about only eating peanut butter?

I am a student who is a very picky and health-conscious eater and have grown tired of the food offered in the cafeteria. A good portion of my dietary consumption is in the form of natural peanut butter. I can sit and consume half of a jar in one sitting because I get so hungry and it is the only thing that really satisfies my hunger. Is this a bad thing, and if it is, how can I go about fixing it?


Do male-identified people have body image concerns?

1) My boyfriend, who I have been dating for a while now, says that he is fat and I don't think he is. He is built, but he isn't fat. And he talks about it all the time, and I just don't know what to say to him. He said that when he used to talk with his other girlfriend about it, that she would say, "well, go on a diet," and he said that made him feel like he was fat. And I don't want to hurt his feelings, but I know that by losing weight, he would feel better about himself. But I like him for who he is and how he looks. But what should I say to him when he says things like he is fat, do you think I'm fat, etc.?

2) I am a male, 24 years old, height 5'10", and currently I weigh 143 lbs... When I was 17 or so, I weighed a hefty 190 lbs... at that time, that really had a negative effect on my self image, and now at 143, I still don't think I'm thin enough... I have lost all my weight 100 percent through diet and running about 20 miles/week... but I don't eat enough and I always worry before I leave home if I "look ok"? Do I have serious issues?!?


Is hot sauce the source of my anal aggravation?

I enjoy my spicy foods. In fact, the spicier, the better. If I break a sweat when I'm eating, I've made a successful meal. I'm extremely active, physically, and I rarely get sick. I don't use tobacco, but I drink coffee daily. I average about two bowel movements a day, and I've found within the last week or so, blood on my toilet paper when I wipe my arse. Can the blood be caused by my spicy foods? I had my wife check out the area in question, and she says that it doesn't look like my rectum was bleeding (but it sure felt like it for about two minutes). I just wanted to know if the spicy foods can actually cause bleeding around there, and if so, does this mean that the bleeding could be caused in other places within my digestive system?


Are other drinks besides water still hydrating?

I frequently hear that beverages with caffeine or alcohol are not good for replenishing fluids and preventing dehydration. But in reality aren't they just a bit less effective at hydrating your body than other beverages? In other words, if you were stuck in the desert with nothing to drink but beer, coffee and cola, would you actually be worse off and die of thirst sooner if you drank these beverages versus not drinking anything at all?


Is my hair loss due to my vegetarian diet?

I have been a vegetarian for two years. Since last year, I have been losing quite a bit of hair. I have no pattern of male baldness in either side of my family. I do take multi-vitamins everyday. My diet is fairly nutritious. Could there be any correlation between my vegetarianism and the hair loss? Some books point to folic acid deficiency so I have made an effort to buy vitamins with 100%-200% RDA recommended folic acid. Do you have any ideas on what might be causing this?
