listen, even if you were bad all week, we can make it better because it's time for "sunday housecall." joining us dr. marc siegel associate professor, author of the inner pulse, unlocking the secret code of sickness and health. >> and dr. samadi, chief of robotics at mt. sinai center. always good to see you every sunday at this time. >> there's always hope for all

of us. you transformed eric and i. we want folks to pay attention. we have good information today. >> back from san diego. >> that's right. >> great time. >> trying to stay younger. in this new study we're going to first start talking about. we know now there's a link between the heart and our brain. turns out factors that help raise the risk of heart disease they say could also negatively affect our brain function. dr. siegel, what does that mean? are we talking about cholesterol and this sort of thing. >> i think this is an important study. this is out of the netherlands. it looked at 3700 patients. we already know people with heart disease have -- as they get old they have a problem with cognitive impairment. what's cognition? thinking, reasoning, learning, language, memory. okay? that's what we already know. this study looked at people who didn't yet have heart disease. they had risk factors. they had some of the ones you mentioned, high cholesterol, essure. number one they looked at was

smoking. they found that young people beginning at the age of 35 were already starting to do more poorly on these tests for thinking that i just mentioned if they had those heart risk factors, high blood pressure, diabetes, smoking. they found people that smoked up to 15 points per day do two points less on the test. more than 16 cigarettes a day, three points less. why? i don't think it's due to blood flow to the brain. i think it's due to the fact blood vessels in the brain are similar to blood vessels that lead to the heart. i think we're looking at arteries here. as they get clogged up, or as they get diabetes, they don't funk as well. cigarette smoking clogs them. we have to do another study where we literally look at brain vessels. >> what if you don't smoke and you have these risk factors anyway? >> if you don't smoke and you have these risk factors anyway, you can do a lot to control them. you can get sugar under control,

exercise, eat right. things we talk about every week on the show, get them under control. >> dr. samadi, what do i do if i go to the doctor and i'm concerned it's happening? >> what's happening to you? are you forgetting things? is your memory going down? is it a progressive thing? is there a family history of dementia? the doctor has to dig in. what he has to do, he knows what's not good for the heart is also not good for the brain. we also know as your stomach gets bigger you don't have that problem. as we get more obese, the brain almost shrinks because hippocampus, memory center, doesn't function as well. >> a lot of those risk factors we talked about, obessity, diabetes, smoking is on the top of the pyramid. as marc mentioned you would have basic constrictions. blfs don't bring enough blood to the brain. risk factors of coronary artery disease. arteries are small. think about the arteries in the brain, they are even smaller.

there's not enough room. it's the same systemic problem. how do you take care of this. eric, you're in trouble. we've got to take care of this. besides exercise and sugar and all this stuff we talk about, last week we talked about fountain of youth and blueberries on top. they should be brainberries they help antioxidants, et cetera. salmon, all those are great. alderberry. when of think of brain, go nuts. everything with nuts are good for you. >> weighing in, inflammation, i want to ask if those folks taking a baby aspirin a day if this would be helpful also. >> didn't look at it. probably very smart, improves brain function. >> point well taken. all these diseases lead to inflammation. inflammation causes plaque, low blood flow. one of the things you should do, if you're under a lot of stress, which i know you're not, also get a monthly vitamin b-12 shot.

that's a joke. vitamin b-12 always boosts your brain and energy. >> check your level. >> if you need it. >> if you need it. >> not everybody does. >> baby aspirin and fish oil. >> dr. colby isn't making any recommendations. >> mediterranean diet works. >> olive oil, we love it. not with bread. meanwhile, here is another thing. you've got smoking 16 cigarettes a day, people are still doing that? if you're still going to tanning beds, too, you're about to find a warning. the fda actually wants to see a new proposal going forward where indoor tanning beds come with cancer warnings. doctor, do people need to be reminded how dangerous they are? >> absolutely. this is a follow-up to the segment from last week with melanoma. the risk of melanoma among teenagers, 20s on the rise. 2.3 million teenagers going to tanning salons so the risk of melanoma, which should be 40s and 50s are high.

we also got a lot of phone calls from wonderful dermatologists out there who loved the segment last week. their point now, this is a huge step forward. fda saying younger than 18 years old don't go there. also they are moving up the risk from low risk to moderate class to risk for tanning salons. they want it on websites, brochures. it's a huge step forward. is it enough? we'll see. about three months from now, there's going to be new guidelines pushed by fda. i think it's a great idea. melanoma kills. >> i think about tan mom. should kids need parents permission to use tanning beds? they don't right now? >> i'd like to see that. i like where the fda is going here. i worry it will only get on pamphlets and won't get to people who go to these things. 2.3 million teenagers using tanning salons. increases melanoma, nonmelanoma, why do people need these tanning

salons. there's compelling scientific evidence dem stralgt ultraviolet radiation from indoor tanning devices is associated with increased risk of melanoma and nonmelanoma skin cabser. in fact, the risk of developing melanoma the deadliest form of skin cancer increases 75% for individuals who have bern exposed to uv radiation from indoor tanning and the risk increases with each use. it's both kinds of ultraviolet light. >> what about protection? those places sell sunscreen. >> fda does say less amount of time you're in there better. maybe in some cases these devices work, maybe they don't. best use is to avoid. fda stepping up regulation, indoor tanning, wait a minute, we're losing money. what about the economy? this is unsafe. this is dangerous. >> suntan lotions won't work.

65% of the people who have gone there have had some sort of sunburn. the other thing, a study from missouri, they notice about 10 to 12 years old without parents permission got in. >> 10 to 12. >> 60% got in without parents permission. that was an excellent question you brought up. i think this is a great step. it's going to be following up. after 30 years it's good fda kicked in. >> can i let people in on a little secret. you don't have to go to the tanning beds. look, look at us. fake bake. >> i wear my suntan lotion. >> by the way, david's point about sunburn is a really important point. people are not taking this seniorsly and it's time they do. >> you brought up a great point. thank you for talking to us about it. eric. >> it's not just suntanning on george clooney, dr. samadi, the rest of us, a stunning new discovery happened this week.

scientists have a new theory now on the cause of gray hair. do you have it? you're going to want to stay tuned to find out about a permanent cure. >> wow! also, this one could actually help after all the mother's day treats. control room, eat the red velvet cupcakes i baked today, please. we have a medical procedure that actually forces your body to eat less food starting tomorrow. >> hi, i'm stationed in southwest asia and i would like to wish my mother of gulfport mississippi a very happy mother's day. i love you, mom. and i hope to see you soon.

braef back now with "sunday housecall." imagine getting older without the gray hair. grays could be a thing of the past. a team of researchers are developing a treatment that could take care of the problem. >> a study out of england, looked at 2700 patients. they have known for a while hydrogen peroxide has something to do with the problem. if you increase hydrogen peroxide in the hair, it decreases a chemical which makes melanin, which makes gray hair. if they get prevent it in the air, they could prevent gray from occurring. in 2700 patients it had an impact. there's a future for a drug that blocks hydrogen peroxide. it's all very chemical. i think this has a lot of potential. i'm not exactly sure why people should do it.

look at dr. samadi or myself. we're fine with a little distinguished gray. >> david, what do you think about the finding? >> i think gray hair is perfectly find. >> of course. >> a lot of this is genetics. it's premature. my father at 35 went all gray. stress is a tremendous risk factor. look at the presidents coming in, three years later they are gray. a lot has to do with the body, the defense mechanism. as we age, some of the enzymes, some vacuum cleaners around our head like catalysts. as we age those vacuum cleaners won't work as well. it's not good for hair follicles, almost bleaches hair from inside out. what if you put it back in. that's what the study in. they have something that may show up in our shampoo, medications, et cetera, and that would increase the melanin. what's interesting about this, a lot of the study comes from

vitiligo. michael jackson made it famous. they started using it on the skin. it's activated. the skin got melanin and got the color back. we're hoping this will help. >> vitiligo, talking about the areas of the skin without pigment that you see. this reversed that. >> if you've got gray hair it happens. keep it, or maybe get your hair colored. >> the patients love it. george clooney, you better watch out. >> it could be it's healthier than the hair dye we use. >> go gray, stay gray, it's fine. >> this is big news this week. it's a personal health thing with new jersey governor chris christie but it did draw new attention on a specific type of weight loss surgery. it also brought growing questions over the risks and benefits and that's coming up in our "sunday housecall" segment. we'll be right back. urn come between us and what we love.

to treat my low testosterone, my doctor and i went with axiron, the only underarm low t treatment. axiron can restore t levels to normal in about 2 weeks in most men. axiron is not for use in women or anyone younger than 18 or men with prostate or breast cancer. women, especially those who are or who may become pregnant and children should avoid contact where axiron is applied as unexpected signs of puberty in children or changes in body hair or increased acne in women may occur. report these symptoms to your doctor. tell your doctor about all medical conditions and medications. serious side effects could include increased risk of prostate cancer; worsening prostate symptoms; decreased sperm count; ankle, feet or body swelling; enlarged or painful breasts; problems breathing while sleeping; and blood clots in the legs. common side effects include skin redness or irritation where applied, increased d blood cell count, headache, diarrhea, vomiting, and increase in psa. ask your doctor about the only underarm low t treatment, axiron.

and said it, new jersey governor chris christie that he had lap-band surgery. it's not the only procedure, though, that you can go through to lose weight. there's gastric sleeve and many other things can you do we talk about here on "sunday housecall." what about benefits and risks of that procedure. dr. samadi, you're a surgeon. surgery is surgery. there are risks involved. >> we've come a long way. certainly there are a lot of options, gastric bypass is an option, which is a little more invasive and takes a little longer to do the surgery. they have to stay in the hospital. he underwent lap-band, less invasive, done in ambulatory surgery about an hour or so and it's reversible. that's the main advantage of

this. they basically put a silicone belt around the stomach to make it smaller. it's a restrictive pathway so you would eat less and feel fuller much, much faster. you can adjust it. there's a port to put in more saline and make it tighter. risk factors, besides bleeding, in fact of the port. you could have esophageal contraction. you could have reflux, things will back up, but your doctor will adjust it. the key point is there's no quick fix. you said it during the break, they have to be on at least two weeks of liquid diet, then soft diet, then eventually to solid food. you need to have a nutritionist and make sure you continue to do the exercise, et cetera. so you can't just depend on this. you lose about a pound a week and it may go on for a couple of years. so you end up doing quite well. more importantly, the diabetes and high blood pressure, which is a result of this, will disappear. >> many people can get off their

medication, which is a great thing. it isn't a quick fix, especially if you can't stick to a diet before, chances are you won't do it after. >> that's a good point. i struggle with this. people come and say should i have lap-band surgery. the first question for me is are there any underlying causes of obesity, do you have thyroid disease? are you exercising enough? what is the reason for obesity. a good internist will look into those reasons. if your body mass index is over 40, weight for height, what's your weight for your supposed height. if it's over 40 you have to seriously consider this. or, as david mentioning, if you have underlying conditions i'm worried about, high blood pressure, diabetes, insulin resistance that goes with diabetes. these conditions, which are metabolic, have to be treated. if i don't treat them -- i have to tell you, i'm not a big fan of lap-band surgery but if i'm looking in the eye of a heart

attack or stroke, diabetes, i will do anything i can, including lap-band surgery. forty minute procedure. the procedure itself isn't that difficult. >> it's a last resort, not a first resort. >> you said something else i want to comment on. after the surgery, you have to follow up closely. are you getting nutrition, vitamins, minerals, following along. if you don't follow diets you're supposed to do, you can't have the same amount of food. small quantities. >> it's not all negative. i think a lot of patients, over 200,000 done safely. safely surgeons can do a good job and a lot of times it can save lives. >> pick the right surgeon. >> always pick the right surgeon, as we've talked about before. >> gray hair. >> it doesn't make your diabetes go away but it can control your sugar, which is extremely important. for patients that can't do it any other way, this is the way. >> see your internist first. i like that. >> if you don't want to do the lap-band surgery or any surgery,

>> eric: back now with sunday house call. the studies show, the faster we eat, the more we get fat. for sneaky bay -- sneaky ways to eat less. how do we do is it. >> we have to relax and have conversation. spices help a lot. cinnamon, tumerrick, rosemary, thyme. they signal a hormone to slow the brain down. this is what you want to do. have a conversation. enjoy your food. >> eric: david, slow down? >> the best thing is slow down. you let the stretch receptors in your stomach to send the signal that say that you are full. when you eat to fast, you don't allow that.
