david samadi here as well. dr. siegel, the author. we've got it all for you folks today. great to see both of you. >> thank you. >> this was interesting this week. there's some new evidence that the leading cause of death in america is likely preventable. 25% of the time. the study is raising questions, as you can imagine, on one issue in particular. heart it is. we want to start with dr. siegel and ask you, preventable sounds really good. >> especially when we're talking about the number one cause of at the time in the united states. one out of three deaths in the u.s. are caused by heart disease. 800,000 deaths rb heart disease, stroke, high blood pressure. 200,000 of those are preventable. now, how are they preventable? the first thing you've got to look at is lifestyle. we've been talking about it on the show forever. diet and exercise. dr. freeden, head of the cdc and probably the top preventive medicine in the country, i interviewed him and he said exercise is the wonder drug. the closest thing we have to a wonder drug. because it increases everything you want to in

david samadi, chairman of yourology in new york and chief of robotic surgery. >> good morning. >> and dr. marc siegel is here, associate professor of medicine, also author of "unlocking the secret code of sickness and health." good to see both of you. we're going to begin with this alarming new research question, which women should get mammograms and whether screenings at a young age could help save lives. a new study has found a majority of deaths resulting from breast cancer occur in younger women who do not have regular mammograms. dr. samadi, what do you say? >> we have gone around the whole circle in the last five years. if you recall a segment from 2009 when u.s. task forces came in and said no, ma'amgrams between the ages of 40 and 50 because we were finding deadly cancers start at the age of 50. do every other year mammograms and you're fine. i'm very pro screening, whether it's psa for prostate or for mammogram, and these two diseases are identical. same number among men and women. they go parallel. anything we say about mammogram is true for psa tests. we said early diagnosi

david samadi is chair of yourology, also a fox news medical a-teamer.s talk about the peanut butter first. what is the deal with peanut butter and breast cancer? >> this is a very interesting study, and it just was published this week. and what they're saying is that if you are taking two portions of peanut butters ages between 9 and 15-year-old, by the time you become 30 years old, there's 39% lower chance of getting breast cancer, a major study coming in. and part of it is because it reduces the benign breast tissues; cysts, fibroids and those kinds of things. so what i like about this is the fact that they followed this up for many years, and it started in 1996, about 10,000 patients. what i don't like about it is that it's an observational study, and we don't have any control. but you know something? what you learn from this is if you're going to go for some of these sweets or sugar drinks, you can replace it with peanut butters and nuts -- jenna: anytime we talk about peanut butter, we have to talk about people with really bad peanut allergies. is

david samadi is here, we've got to wash our hands because of flu season, on the other hand, if you washuch maybe you might get alzheimer's? how does that work? >> well, i certainly don't want to dismiss. we have talked about this in kids when it comes to allergies, the fact that their immune system is really young and they are not exposed to bacteria, so they haven't really built up a lot of immunity. whether it's going to be the same kind of idea for alzheimer's in the elderly, i'm not sure. but we've spoken about the fact that alzheimer's is becoming a real problem. men and women are living longer and longer, and the numbers -- jenna: some of the statistics are startling, different ones being used, one in three people will suffer from some sort of dementia in their life. that's a very high statistic. >> absolutely. and we have over five million americans suffering from this disease as we speak. those numbers are going to be close to 20 million by 2050. so the question is, is it really the wear and tear and the fact that we're living longer? we never used to have all the cardiac stents

david samadi. it seems to change. what is it at now? >> over the age of 50.o finds a lump and has to get a mammogram. we're talking about screening. this screening has been a big controversy for the age of 40 to 50 for breast cancer and prostate cancer. this debate has been going on. we know screening helps and that saves lives. you see the mortality reduced over the last few decades. so screening absolutely helps, and we want women and men to go for their screening. what we're talking about here is a study coming from harvard and they looked at about 7,000 women, followed them for about seven years. out of the ones that died from breast cancer, a majority of them, almost 70% of them never had mammograms. out of that group, a lot of them were under the age of 50. what we're trying to say is when you diagnose breast cancer in women between 40 and 50 they are very deadly and aggressive and screening saves lives. critics are saying if you go for it you may find cancers that may not kill you so there is overtreatment. the answer to that is that knowledge is extre
