time now for "sunday housecall." hello, everyone. i'm julie band race in for arthel. >> and i'm arab shawn, bump as always. joining us dr. marc siegel director of medicine at langone medical center and author of "unlocking the secret of. >> and joining me also is dr. david samadi, chief of robotics surgery. >> jappy july fourth. >> millions of people will be gathering, a time of reflection and celebration for our country, and, unfortunately, a time that can also result in trips to the

emergency rooms. dr. siegel? >> you know, we've talked a lot about it before about barbecuing which clearly everyone is going to be doing, and i don't want to go over old ground except to say check with soap and water to make sure there's no leak coming out of your gas part of the grill. separate your raw meat from your cooked meat. eat a lot of vegetables, don't eat 5,000 hot dogs. if you drink -- >> not a hot dog eating contest. >> if you drink ten beers, don't drive. stay hydrated but i want to ad something today which is fireworks. >> oh, yeah. >> everybody is setting off the firecrackers, and the first thing is, air, i don't want kids under the age of 5 anywhere near this. don't think a kid could set off a sparkler. i don't want kids lighting sparklers, i don't want young kids at all near this. as watch out when you're drinking do this. also, don't go throwing this anywhere. light a firecracker, don't throw it anyway. you think it's funny. it's not. people get injured. over 7,000 visit to the

emergency room and you can lose a finger, throw into a place where there's dry grass or some place where it can catch fire, you can set a fire off. a huge probable. >> a lot of people with bottle rockets, and i grew up and put them in bottles. a lot of times on the beach people hold them in their hands and let them shoot out of their hands and that's asking for trouble. >> absolutely. let me say happy fourth of july and for us who come from other countries this is a great moment to celebrate and we're all proud to be an american, and getting back to your question, temperature in the hand of these can go up to 1,000 degrees and burn off hands and arms and a lot of injuries. yes, you should go celebrate but keep the kids away from the fireworks, that's number one. what i see a lot of times in the emergency rooms are people that are drinking, but they don't realize that had half drunk, they are out in the sun and being dehydrated and after a few hours they are drunk and start swimming and that's when you run the risk of having drowning and other things. and this is also a weekend where the number of car accidents goes

up skyrockets, that's what we see in the emergency room. a lot of times, julie, they may not feel like they are drunk, get behind the wheel, texting and letting the pictures from the fireworks to their friends and that's when you will get car accidents. be careful. i think grilling and having like some fun food, i'm okay with it. we've talked about all healthy foods, you know, 50 weeks of the year. this is a time they can loosen up and have their hot dog and hamburgers. i have no problem with that. >> i want to add, by the way, if you're going to barbecue or if you're going to use fireworks, have an emergency kit around. if you get burned, either from a firework or grill, put it under cool water. have an expert around. that's why i'm going to a barbecue at his house. you want a surgeon around. you can tell the difference between second-degree and first-degree burns because second-degree has blistyinging to them. larger than the palm of your hands, go to the hospital. and third-degree burns,

automatically go to the hospital. >> should you go to the hospital with a second-degree burn? >> absolutely. don't want to treat it yourself. make sure you go there because they can prevent it and treat it very rapidly. other thing we see kids, they have the whole three-day weekend so they are out in the sun and also sunburn is another problem so make sure you use the spf at least over 15. >> right. >> and every two hours apply. but, you know, this is a fun time. >> it's a whole long weekend of fun. >> by the way, more than welcome to come to our parties also. >> he's got the emergency kit. >> i don't cook but i will come. >> falls in the pool and has the emergency kid. >> i'll bring my floaties. >> and testing the grill with soviet union and water. what do you do? how does that work. >> first time you're using it and haven't used it all year it can have leaks and we're talking propane. if it has a leak, and you light a match, use soap and water going on to the grill. >> you talk about drinking, people should be drinking a lot of alcohol and we should remind

people to drunk a lot of water. i've done it my investment you start at 10:00 in the morning with the bloody matter and by the afternoon you're drinking beer. >> and you're dehydrated on top of that. >> and wine. >> i've never done this before, but the mistake is swe forget to drink water and that's the problem. the dehydration is serious. >> dehydration plus alcohol and start jumping and diving and those kinds of things and that's when you'll have a lot of accidents and always, have a couple of people watch the entire group and if you see someone who is not doing well, don't let them jump in. >> great point. >> especially with kids around the pool. >> absolutely. >> it's easy for the grown-ups to go off and have a couple of drinks and enjoy life and you're thinking the kids are out there having fun and something potentially could happen. >> i want to emphasize julie's point about water. never too late. before you start drinking water. while you're drinking, two-fisted drinking. wann water in one hand and always the other. >> double fisted to me is two cook dals. water and my cocktail. >> and after you drink it's the best treatment for hangovers. >> talking about mixing alcohol.

>> yeah. it's a good why the. water makes all the difference and when you are drinking over the course of several hours you're not necessarily feeling drunk because it's a slow day drinking, and this is where the water and the dehydration became a big issue, especially when you're in the sun and you have over sen exposure. >> somehow you know a lot about alcohol, that's fine. >> i've done my research, david. i've done my research for years. >> to david's point about watching over the area, you know, kids especially, if you're drinking, better make sure someone is watching your kids because they can fall in the pool. you can say where does johnny go? >> a designated driver and a designated parent. >> absolutely. >> watch the kids. >> and plan ahead, too. if you know you're going to be drinking, first of all, pack be a overnight bag and sleep wherever you're going. no need to try to figure out what to do at the end of the day. >> you got room for me, dave? >> absolutely. it's a fun weekend. >> having fun. >> and celebrate our country. >> that's the most important thing. >> get the flag out. >> get the flag out and be

careful when i put it on the second floor don't lean out too far with the screen less. >> especially, eric, with everything going on, not to get into the politics of this, but it's priceless to be an american, and with all the pressure all over the world, this is a weekend you want to go out and celebrate with your family and we get some rest, too. >> non-partisan celebration. we're americans and celebrating america. >> happy 4th, everyone. >> happenyth. >> the latest diet craze out there, yet another one. eating normly, and then once every few weeks shock your system into thinking it's starving. so does it work? and is it health? we'll ask the doctors next. ♪ [music] jackie's heart attack didn't come with a warning. today her doctor has her on a bayer aspirin regimen to help reduce the risk of another one. if you've had a heart attack be sure to talk to your doctor before you begin an aspirin regimen.

mimics fasting. dr. samadi, what's this all about? >> julie, there's lots of ways to lose weight, a new fad that's coming out and that's fasting. a study that was published that looked at 38 patients. half of them had normal diets the other half went on fasts for about five days a month, and what they followed them afterwards they realized the ones that fasted, meaning they took 750 calories a day, they ended up having lower amounts of fat, cholesterol went down and risk to vardio vascular went down and they were healthier. did the same thing in yeast, mice and human and the same pattern. taking a break from animal fat, sugar, and all the fatty food we're having and tyke five days break of very low calorie intake, you become healthier, so there are pros and cons. i think it's not a bad idea to do it for a couple of days, ng, lower the amount of calories that you take, just to break the cycle of your routine, eating the same kind of food all the time, but if you do it for prolong period,

five days, a week, i think that's when you run into trouble of muscle wasting, when you don't get enough protein you'll affect your whole entire body so i don't like to do this for long periods. short term it's okay. >> marc, what would you do? what would you fast with? just protein? >> mainly protein and we're talking about 725 calories the first day and then 1,000 for the next four days. now, in mice this showed that they actually restarted their immune system. i'm calling this pushing the restart button. in other words, slowing down the metabolism. if you've been having inflammation on your body, pre-cancer, diabetes, heart disease, this is pushing the restart button, but i want to put a cautionary flag on this because there's a lot of people out there that have underlying illnesses who cannot afford to have a fast something like this for five days. if this catches on and becomes a fad, eric, you know what will happen? people will get hurt and sick from it. it may work in mice and what's

interesting in mice they started making stem cells so i believe there's something to this scientifically. restarting the metabolism but for humans 38 people is not a big study. needs to make more of this. makes sense conceptually but i would be cautious because of people's underlying diseases. >> if you really remember, julie, last week we talked about how you can change the ecosystem of your bacterias, good and bad back the yeah, and this probably, as marc mentioned, it's a reboot of your system. you're basically starting from scratch. you're taking a few days from your routine diet and changing some of those bacterias, and for mice to actually create new stem cells, that's a good finding. it may not be ready for prime time but it's an interesting finding. >> similar to a cleanse, big fan of doing a three to five-day juice cleanse, you feel rebooted and have more energy and all of that, and the problem here and here's the con, when you start to lower the intake of fat and calories, doesn't your body start to produce its own fat?

it's sort of the whole notion of if you skip meals it's not good for you because if you're starving yourself your body is going to produce more fat and you're not netly going to lose weight that way is it. >> a very important point and what you're losing, by the way, is first few days is all water. 70%, 80% of your body consists of water and that's the ray they are lose and that's why they are gaining back right away and that's one of the reasons why i said i don't like the fact that it's going for five to seven days because you're starving your body and you're going to basically build up more fat, i agree. >> what you do is actually break down your protein. take your protein and muscle. >> good protein breaking down that you don't want to do. >> and you're fasting, and the cleanses are very variable. >> check with your doctor first. >> julie is doing the right kind of cleanse but make sure whatever you do has enough protein because orth wise you'll break down the protein. >> fat is the source of energy, highly dense, and when you run out of bank and don't have any

currency anymore you'll go to another bank which is protein and you'll start getting into muscle wasting and your point is well taken. >> what's the best type of diet? >> one thing is for sure, and we've talked about the mediterranean. the best dip of diet is low carb, no bread, low in pasta, low in rice and low in cookies. get rid of those carbs. >> low starch. >> no processed foods. no processed foods. >> can you do brown rice? >> look, it's better than white rice, but processed foods are the worst. >> why did you bring brown rice? >> supposed to be really good. >> because it has a lot of vitamin b and has some protein in it, that's true. >> high fiber is the key, fruits and vegetables, less meat, mediterrane mediterranean. >> white foods are the enemy where all the sugars are packed. >> and also portion control. >> that's the key. >> absolutefully. >> glass of red wine here and there? >> or two.

>> yeah. >> happy 4th. >> coming up, we'll talk to you about a rare and critical test that can detect how well the blood flows in your heart. we'll tell you what it is and what it means and how you can prepare for it while we contemplate the diet.

. and back now to "sunday housecall." and our segment should i worry? a weekly segment in which we talk about everything that worries us. one viewer writes i'm a 53-year-old woman, never smoked and in great shape and have been scheduled for a thalium stress test. should i worry. dr. siegel, why do you think her doctor suggested this? >> we don't have enough information. if she has a family history of heart disease, not having any symptoms, no chest pain, high

blood pressure, high cholesterol and exercises a lot and is about to do a marathon and want to know if she is a risk, those are reasons to consider it, but consider this, eric. what's called the pre-test probability with a stress test, a thalium which is much better. >> what is that? >> what a stress test is you run or walk someone on a treadmill and watch to see what happens and simulate what's called the increased workload of the heart and when the heart is under stress you look to see if there'sin an example of some narrowifainarrowinging going on. 80% of the coronary arteries have to be narrowed before it comes out on a stress test. 70%. why am i saying that? you can have disease to the arteries of your heart and a stress test wouldn't show it. it's got to be really narrow before it comes out. it's also overdone in some people. not everybody over 50 should have a stress test. i told you the reasons. if she has a risk, real risk then i might -- or diabetes is another risk factor i might want to do it knowing that the pre-test probability, the chances of her having a problem, is only 80% to 90% that a stress

test will make it up. not 100%. stress tests miss the problem and will sometimes you have it when you don't have it. >> what should you do tell you when you don't. there are other things you can do, we talked about calcium scoring, a c.t.angiogram. and it's a test that examines function. it's practical. saying hey, if you want to run a marathon, do it under circumstances where we can control it. >> and he deals with this a lot more, but it's good for what are the indications of a stress test. and if you have high cholesterol

and blood pressure, should you go for a stress test? if there's no family history, i don't see any reason why, first of all, are stress tests bei ii overdone in the country? that's what needs to be responded to. and you look at the blood pressure, the whole purpose is to find if there are any blockages in blood flow to your heart. i don't see any reason in this particular patient. >> let me address that. what i should say, the more risk factors you have, the more of a chance you should do this. also if you have

abnormaliti abnormalities. if i see something on the ekg, then i go for the stress test. >> is the thallium thing different? >> what they do, they give you the thallium and look at the heart rate, blood pressure, and see if there's any kind of blockage. if there is, you are going to have a different heart rate. >> the thallium, it's a dye they put in, and it doesn't get picked up by arteries that are blocked. >> and use the e-mail hou

today her doctor has her on a bayer aspirin regimen to help reduce the risk of another one. if you've had a heart attack be sure to talk to your doctor before you begin an aspirin regimen. they affect millions of people, but new research suggests early exposure to allergies may be keeping them at bay. is that the truth, we should perhaps rule them out from affecting us later by exposing us earlier in life? >> we see the numbers on the rise. how many times have you heard, don't give kids eggs or peanut

butter, until they're 2 or 3 years old? a new study says that everything we thought is wrong, and the earlier you expose your kids gently, they start building up tolerance. and they realized when the kids are exposed earlier on, a number of the peanut allergies in the future is a lot less. and so, i think it's okay to expose them, shock can be lethal. so, i think it's good to start early. >> and in the study in 2014, in israel, jewish children were

given peanuts, and they had less allergies. and we've changed our requirements based on this study. they're very excited about this as a game changer. the first time, they literally gave peanuts and peanut butter from 4 months until five years of age, and an 86% reduction. >> how do you know your child may have that allergy? talk to your doctor? >> great point. you have to know who's at risk. but we may be causing allergy by prematurely taking foods away. and the body says, i don't see that. when it finally sees it, they make an allergy to it. >> when we were kids, there were

no rules with no eggs or honey. now, more andhildren seem to have allergies. there are no-nut policies in schoolrooms because of more allergies. >> and we're using more dete detergent, and you're not exposed. and then your body is in shock. >> makes sense. >> and the kids used in these studies, high-allergy kids. they were taking kids at risk, and think found much less problems. >> and it's devastating to some families, they always have to walk around the epi-pens in

their pockets. if someone becomes short of breath, take them to the e.r. >> happy fourth. >> thank you. >> thanks for watching, everyone. fireworks on the presidential campaign trail. clinton getting blasted for roping herself off and roping the press in. while jeb bush makes it personal. going after donald trump for his comments. and it's decision day in greece. on a decision that could determine the nation's future. we're live in athens. >> plus, game on, we're just a few hours away from a long-awaited rematch from the rival japanese and u.s. women's
