sunday morning tragedy to report. four passengers have been killed in the passenger train derailment in new york city. at least 63 others have been injured. as you can see from these live pictures, it happened earlier this morning in the bronx. looking at the aerial video. we're told that four of the cars at least ran off the tracks as this train which was traveling from poughkeepsie new york to grand central terminal in manhattan flew off the curve just a few miles from the spuyten duyvel station. they're searching for victims, but again, the death toll now sadly sits at four. >> just to give you more details

on this. there are police dogs on scene looking to see if anybody else needs to be removed from these trains. dangerously close to the water. there were police crews also in the water. it's an all hands on deck situation, including new york governor andrew cuomo, who was on scene along with new york city police commissioner ray kelly. they're asking that we just allow the investigators to do their job. the ntsb will listen to the black box and determine how fast the train was going. at least one passenger who took the train every sunday, he said, felt it was going way beyond the speed it should have to get ready to pull into a station. again, four people killed. 63 at least injured. four area hospitals are on scene. coming up later today, we'll talk to one of the hospitals and one of the doctors from the hospital, an emergency management specialist who will tell us the injuries they're seeing and what it takes for a hospital to respond to a tragedy of this magnitude.

>> authorities not speculating on exactly if speed was a factor in this. that's all part of the investigation as the black box, they say, is on the train and will be recovered. >> we'll be right back with much more. stay with us for the very latest on this train derailment. and i'm jamie colby. great to have you here because it's time now for "sunday housecall." >> i'm aeric shawn. joining us, dr. marc siegel, associate professor of medicine at nyu's langal medical center, also author of "the inner pulse." >> and dr. david samadi is with us. chairman of yourology and chief robotics surgeon. good to see you. >> we begin today, we talked about testosterone the other week. now there's a new warning from the fda saying a chemical found

in common food items like french fries, potato chips, and cookies can actually cause cancer. cancer-causing chemicals in what we love? >> we're going to talk about the testosterone topic, too. >> we're talking about a chemical called acrylamide. we already don't like the food that acrylamide is in. we have been talking about it on the show for a long time. we're starting off in a good place. we like fruit and vegetables. that doesn't have a lot of acrylamide. we like low-fat dairy. you know what has acrylamide. it's a chemical that's formed by processi sugars and amino acid like a kimical equation and it forms acrylmide in stuff like french fries, toast as it's browning. as your food is browning or as your french fries are frying, you get acrylamide.

the more you fry it, the more you get acrylamide. the thinner the french fry, the more you get acrylamide. the fda is saying let's watch our potatoes, use more mature potatoes. what is acrylamide? it's been shown in rodents at high doses to be associated with cancer. in humans, the information is not in yet. the studie in. eric, your question, what do i do when i go home? we don't have proof that it leads directly to cancer. in fact, studies have not shown a connection to breast and prostate cancer, but maybe some association in humans with ovarian cancer. >> the rats and mice, do they stuff their faces full of french fries and get cancer? how do we know this potentially could harm us when they have that in the lab? >> one of the greatest things about "sunday housecall," and i talk to people on monday morning, they want to know what to do for the next coming week. and sometimes we do the dance because we're kind of in a tight spot. because some of these proofs and

research haven't shown that acrylamide causes cancer. i would very quietly and calmly say to people to be careful. in ten years when the real result is out there, theiwe're g to look back and say we had a hint. they said potential cancer, so there are hints of it. this comes from studies from sweden ten years ago. they say if you make your french fries and potato chips, don't make them too brown. make them gold. that was a nice hint. ten years go by. we forget, and it's overheating. when you have amino acids plus sugar and you overheat it to what temperature? 250 degrees. the more you overcook, more you overheat it, you can cause acrylamide. >> fewer french fries, not well done. >> people are going to eat some of them. >> look, you can't avoid it. 40% of calories in the american diet have acrylamide.

it's in our water, in the paper, in the plastic. its rar everywhere. you can't avoid it. >> can we get rid of it? >> you can decrease the amount you have. one of the ways is not using the thin french fries and frying them. i'm not going to point to the particular fast food restaurants that have them. >> actually, eric's point is well taken. you should call for acrylamide out of our diet. what the fda is saying, don't store your potatoes in the refrigerator. wash it beforehand, and now you can add acrylamide next to salt, sugar, and transfat as the enomy in our diet. >> it doesn't even sound tasty. >> not good for you. >> a lot of people asked us after we told you about low t, testosterone levels in men, and how they should have it checked. now they're reporting a shorter life span. what's the story.

>> testosterone as a yourology is extremely important, vital to your health. important for bone density, muscle mass, losing fat. you can't live without testosterone. the peak in men is age 30. as we age, every year, you lose about 1% of testosterone. when you get to your 50s and 60s, a gradual male menopause, which we have spoken about. what do you do? all these ads on tv, get your testostero testosterone, macho man, six pack, doesn't really help. too much testosterone, based on the study from sweden, shows it can reduce the size of testicles, causes infertility, make sure you gain fluid retention and acne. based on the study, you want to moderate your testosterone at a moderate level, not too high, not too low. number one, see a yourology, get

your testosterone, 7:00 in the morning, that's when you want to do, and it's not randomly taken. we want to see if your prostate is enlarged, if you have a history of prostate cancer. >> what's ingood number? >> your total testosterone should be over 400, and your free floating testosterone should be 900 and 1600. we'll post it on facebook. >> the big list they give you when you go to the doctor, is it on there? >> i check psa on everyone over 40. testosterone in everyone over 50. people who are overweight, getting fatigued, getting tired. if they start to develop diabetes, that's another issue where testosterone can be a problem. get your physician to check your testosterone. what do we do if we find low testosterone is the question. we may be wanting to replace it, but we have to be careful.

the study we talked about last time showed it could precipitate heart disease in men over the age of 60. the study this week showed maybe the medium level of testosterone is the best place to be. but we have quadrupled the amount of men getting prescriptions for this in the last ten years. >> when you go to the doctor, ask him. coming up in a second, you use them every day to keep in touch with our loved ones and business and everything else. well, cell phones and those studies about potential cancer. our medical a-team will break down the potential risks. also, the holiday shopping season kicked off this weekend, we have toyed consumer advocates are warning parents to stay away from. doctors took a look at those and will tell you what to look out for, next.

[ inhales deeply ] oh. what a relief it is.

back now on "sunday housecall." you know at this time of year, toys are usually at the top of most people's holiday shopping lists, but consumer advocates are warning that some toys could be more hazardous for your kids' health than others. dr. siegel, what is the list and what should people look out for? >> first of all, i want to applaud a law passed in 2008. the consumer product safety improvement act has changed the playing field here. it used to be in 2008, eric, there were 131 recalls. most due to lead in toys. the past year, tw2013, so far, lead. there was one toy that i won't mention that did have a problem with lead. you want to worry about lead and cadmium, kids swallowing little things, marbles, noisy things. two leap frog toys caused so much noise, they had to be withdrawn. one out of five children up to the age of 12 are already hearing impaired.

watch out for noise, tiny pieces kids can swallow, things kids can choke on, and what's in the toy they can lick, like lead, like cadmium. we're moving in the right direction. >> what do parents do? it's hard, you have an older child, and then you have a younger one running around on the carpet trying to put it in their mouth? >> you have to pay attention. examine the toys. look for labels and find out if there's lead or cadmium, and anymore it, make sure you separate them and find out if there's anything small enough to get into the mouth of the kids. as a surgeon, we look for solutions. i want people to have some hints. if there's something stuck in the throat, the last thing you want to do is stick your finger in and try to dig it out. you just push it further in. you want to push the kids on the chest and basically kind of hit it from behind and see if you can get the toy or marble out. if something is stuck in the nostril, you cover the other sigh and blow in the mouth like

you're giving cpr. that should push it out. that's the way to do it. if something is stuck in the ear and there's nobody around, use s saline wash to get that toy or whatever the marble is. those are small hints. of course, you call 911 if you're really in trouble. those are the things you should do. 200,000 visits to the emergency room for kids injured by toys. as marc mentioned, we have come a long way. the level of lead and the cadmium is much less, but now there's a whole list of toys, even this year, that had 29 times more lead than it should be, so i think people should really be careful about this because it caused cognitive and mental retardation. >> can i ask you a quick question. on the outside of the boxes, they have the ages. and god bless the easy bake oven. it's how i learned to cook. should you pay attention to the age requirements like 3 or more or 5 or more? >> that's a great point, dr. colby.

very young kids are going to end up getting burned or hurt with something they're not supposed to be cooking at. two other things, fragrances, watch out for allergies. to david's point about emergency treatment, you could have anaphylaxis from a toy, and magnets are something kids tend to swallow. >> good advice. >> i want to make sure that people know jamie is not a real doctor. someone called me and said, can jamie write prescriptions? >> she's an honorary doctor on houseca housecall. >> they're the subject of many medical myths. our doctors are going to weigh in on what you need to worry about when it comes to your cell phones. so many studies, but the real answers are here on "sunday housecall."

it's our "should i worry" segment, a weekly segment about everything that worries us, not just you, eric. these days everyone has a cell phone and there are so many warnings about potential health risks we don't know who to believe. we'll start with you, doctor. should we worry about our cell phones? >> the short answer is i would say yes, even though we really don't have a scientific proof so to show that cell phone causes cancer. my own personal feeling is after you use it about 60 minutes or so, most data shows that the heat around that side of the brain goes up. there's more sugar in your metabolism on that side of the brain. there are mri changes. if you talk to most neurosurgeons they would be very

concerned. this is a big debate. the con, and one of the reasons why we don't think there's increasing risk, is the number of cell phones purchased a few years ago has gone from 100 million to 300 million cell phones, but the number and statistics on brain cancer hasn't tripled. so that's the debate. if we talk to doctors, say that, okay, so we can't prove it yet, but, you know, the companies are saying keep the phone at least two inches away. so they want you to actually use your phone almost like two inches away. nobody uses the phone like this. >> hopefully you use an earpiece. right? >> the best advice is keep it away from the chirp because the skull is thin, they have more activity so you can cause cancer among them. we're going to see the data coming up. until then, texting is better. use the earpiece. if row don't have any kind of reception, your phone the giving away more radiation. this is nonionizing radiation.

we're talking about here. >> use an earphone. >> or text. >> you don't want that thing in your pocket. >> talking about radiofrequent waves here, in between radio and microwaves. the radiation with treatment of canneser is much more man that and i worry about cancer in the organs next the one you happen to be treating. tauing act radiofrequency waves, there's been no evidence they alter dna, which is what you need for cancer, but it warms the brain, causes changes in glucose. the jury is still out on whether it can increase the risk ofcanc. an interpol study didn't show it, but a large study going on right now called cos mow is probably going to give us the answer in a few years. in the meantime, i'm worried about all this texting, because texting, there's a study on virginia tech that shows your chances of having a car accident are 23 times greater if you're texting while you drive. >> i know what men are saying. what about infertilitnfertility?

they carry their phone in their pants pocket. >> a good point, too. that hasn't been studied. the evidence is not in on that either. >> what do you recommend? >> i agree with david's point. i recommend limiting the amount you stick it to your head but i really recommend you don't use the cell phone while driving, don't text or e-mail while you're driving. 25% of car accidents are related to cell phone use. how about talking to each other? that wouldn't hurt. >> how's that? all right. well, speaking of talking, we'll come back with more. got to take a quick break. >> the benefits of exercise. coming up, what if you're one of those people who always puts that off? we'll explain why it's never too late to start to exercise. some healthy tips. ♪ ho ho ho

back now with "sunday house call." a new study says that maintaining or starting regular exercise even in your later years can help improve your physical and mental health. is it ever too late to start? >> i love the message to end the show with. british sports medicine journal says you're seven times healthier if you start to exercise over the age of 65. 2 1/2 hours of exercise is the minimum, even active walking. i love the elliptical. you've heard me say that. biking. something to get active. in addition, the cdc recommends weight lifting or yoga twice a week. ai also like that. you can lose weight, you have less of a chance of getting dementia or depression and all these other diseases i'm treating you for, obesity-related diseases, high pressure, all decreases when you exerci exercise. >> you feel like if you're out of shape, i'll never get back into shape, but no matter what age you can. >> the big message is to start

early because you start building up your bone bank and that's what you would use for the years coming up. now, the nice thing is that the population of 65-year-olds and older is going to grow. over the next decade we're going to have over 72 million more of all the population so we want to make sure we start early on so we have more of this bone reserve that's going to last us and prevent us from osteoporosis. but exercise is not always about losing weight and getting back in shape. now we're starting to realize it will help delay dementia, delay depression because of the hormonal changes as a result of exercise, and overall it's a very healthy thing to do. you know that for the heart, for everything. >> what i like about it is if we can show that video again, i find these folks so inspiring that they're there, socialization. they're out of the house. they're having fun. >> there's a lot of that in the gym and the pool. now a nod to something i attacked before which is that cell phone, that smartphone i was saying don't text while you

drive, you can put that in your ear and listen to a book or some music or on your ipad you can read a book while you're on some of this equipment. if you multitask you lose track of all of that grinding that's going on and it's good for your health. >> i bet these folks sleep better, they have a better attitude about life, they probably take better care of themselves. right? >> what they're doing right now, part of it is the yoga and exercise they do, they will sleep better, they will gainless weight. it's much better to prevent sleep apnea. he keeps going back to texting. i think text is the best technology. if i don't want to talk to dr. siegel, i can always text him. you know, he wants you not to drive and text. but overall, just three hours a week of exercise is the best thing you can do for your health. >> and don't smoke. >> as president bush said, it's addictive. once you start, you don't stop. >> endorphins. >> thanks so much.

>> this was a great "sunday house call." see you next week. that's going to do it for us. >> i'm eric shawn. "media buzz" with howard kurtz is next. here's howie. first we have a fox news alert. the developing sunday morning tragedy in new york city this morning. four passengers have been killed in that train derailment that happened in new york city in the bronx. at least 63 others have been injured who were on that train. we just heard a few moments ago from new york city police department commissioner ray kelly about the continued search for other survivors. here's what he had to say about that possibility. >> well, there was a concern that the -- the cars are close to the water, concern that someone may have been ejected into the water. we used our divers.
