david samadi, great to see you. chief of robotics. >> hello, good afternoon, and hello. we start with something that's really important. you go to the doctor, you want antibiotics because you feel lousy and usually you get them. there's a brand new report that says doctors are still overprescribing antibiotics. the study finds 6 of 10 patients with a sore throat are prescribed antibiotics even though they say only 1 infection in 10 is severe enough to have antibiotics. dr. siegel, you go to the doctor and say, cure me. are antibiotics always the immediate answer? >> absolutely not, eric. this is quite disappointing. this comes out of harvard and they found doctors are prescribing antibiotics for sore throats 60% of the time, the same in 2000. for bronchitis, 73% of the time. the amount of doctor visits has tripled for people having bronchitis. i'll tell you what's wrong with that. sore throats, only 10% of the time are strep, 10%. here we are, doctors like me overprescribing antibiotics. we just talked about the impact. resistant bacteria is thriving. 23,000 deaths per y

david samadi is here. he's a professor, too, and great to see both of you. thank you for joining us. i wanted to begin with this new research in the fight against alzheimer's. there's a study that finds doctors may soon be able to detect the disease years before the first symptoms set in. dr. siegel, how early? >> this is pretty exciting. it's out of johns hopkins and published in a major journal called neurology and it looked at the idea of looking at the fluid that's around the brain, the csf, we call it. that fluid we're going to talk about in the second topic as well, but it's not only a cushion, but it absorbed waste products and protein from the brain the brain makes when it's working. if you have these two very abnormal proteins, if they build up in the fluid around the brain, it may be a marker that five years down the line, you might have a problem thinking. you may be forgetful, you might have a problem with daily activities. you may be on the verge of mild dementia or alzheimer's. if we knew five years in advance, if you could predict five years i

david samadi. >> dr. marc siegel as well. associate professor of medicine at nyu and author of "unlocking the secret code of sickness and health" which is what we do here. >> growing fears over one of the most common foods we eat. almost all of us eat chicken. there's been a big salmonella outbreak from raw chicken and it's getting worse. so far, it's sickened more than 300 people in 20 states and puerto rico and it's spreading. what do we do and how do we prepare our chicken so we don't get this? >> nothing to really panic about. 300 people over 20 states, but what we want people to know is this strain of salmonella is very resistant to antibiotics. this one doesn't respond. what happens with a lot of these infections is people get dehydrat dehydrated. they gets cramps, abdominal pain, and it's the nausea and vomiting that leads to the dehydration. make sure you drink a lot of fluid, and if it doesn't get well, take a stool sample and a culture. >> it takes days to see if you have this. >> the cdc reports over 45,000 cases a

david samadi with us, a member of the fox news medical a-team. ttle bit cancer here. one hour a day, does it matter what type of walking? or brisk walk around the park or walking with your kids or at the grocery store? >> all is healthy. brisk walking one hour a day seven days a week reduced risk of breast cancer by 14%. that is significant. this is medical breakthrough coming out from the american cancer society. jenna, they looked at over 70,000 postmenopausal women. followed them for 17 years. this is a really great study. now we're seeing that just exercise alone, one hour a day for seven days aweek you can reduce the risk. if you do vigorous exercises that can reduce the risk of breast cancer by 25% and that's significant. we know about the health benefit of exercise. i talked about this on "fox news sunday" house call. about the fact that it can besides cholesterol and heart benefits, it can help your mood and sex life, believe it or not. as a urologist i've said that. now we can see it actually can reduce the risk of breast cancer and that'

david samadi joins us now. thanks for being here. relaxation.rd a lot of about the five-hour energies. do these work and what's in them? >> none of us have that kind of problem. i could put my head down and pass out. these actually are completely opposite of what you described. culturally we always want the energizers and trying to wake up. these are supposed to calm you down. i went through all of these. great names. dream water, five-hour sleep. they all have ingredients we give patients. melatonin. gava, which is a mood stabilizeer, antianxiety. they have put them in there and it actually works. a few people tell me this calms them down and it works. if you have a major sleeping problem. this is for people who have tried everything. they have gotten the best mattress and they have made the room calm and they have the same kind of going to bed and waking up, if you tried everything -- exercise, et cetera. you may want to try this. here's the thing. >>brian: you're saying don't get in the habit of doing this every day but if you are having trou
