HOUSECALL" AND JOINING US IS DR.

DAVID SAMADI, CHIEF OF ROBOTIC SURGERY.

>> GOOD MORNING.

>> ALSO DR.

MARC SIEGEL IS HERE, ASSOCIATE PROFESSOR OF MEDICINE AT NYU.

GOOD SEE YOU.

>> GOOD TO SEE YOU.

>> HOPE EVERYONE IS WELL.

>> WELCOME BACK.

>> THANK YOU.

GREAT TO BE WITH YOU.

I'M GOING TO START WITH THIS BRAND NEW STUDY THAT QUESTIONS THE BRAIN BENEFITS OF OMEGA-3s.

THOSE ARE THE ACIDS MOST LIKELY FOUND IN FATTY FISHES AND NUTS.

THEY HAVE BEEN TIED IN THIS NEW STUDY TO BRAIN BOOSTING.

SOME OF US DO AIM TO BE SMARTER, BUT MOST OF US DON'T WANT TO HAVE DEMENCHA, SO CAN WE DO ANYTHING TO BOOST OUR BRAIN, GIVE US MORE BRAIN POWER? >> THE SIMPLE ANSWER TO THAT IS TO EXERCISE YOUR BRAIN.

SO YOU WANT TO BE ACTIVE.

YOU WANT TO MAKE SURE THE SAME EXERCISE YOU DO FOR YOUR BODY AND MUSCLES, YOU DO THE SAME BY READING, PUZZLE SOLVING, AND GETTING ENGAGED AND PLAYING CARDS, ET CETERA.

THOSE ARE EVERYDAY KIND OF THINGS YOU CAN DO.

WHEN IT COMES TO OMEGA-3 FATTY ACIDS, WE HAVE SPOKEN SO MANY TIMES ABOUT THIS.

IT'S TIME TO PUT IT TO REST AND GO OVER THE GOOD, BAD, AND UGLY.

WHAT'S GOOD ABOUT OMEGA-3 FATTY ACIDS IS IT HELPS WITH RHEUMATOID ARTHRITIS.

IT REDUCES INFLAMMATION SO FOR THE HEALTH, IT'S HEART HEALTHY.

IT MAY HAVE ROLES IN DEPRESHZ.

IT HAS GOOD BENEFITS ABOUT THIS.

THE BAD THING ABOUT THIS IS WE HAVE TALKED ABOUT DIMENSIONA AND ALZHEIMER'S.

IT DOESN'T MAKE A HUGE DIFFERENCE IN YOUR COGNITIVE SKILLS AND MEMORY, UNFORTUNATELY.

NOW, IN BABIES, PRENEATPRENATAL, IT MAY PLAY A ROLE, BUT IN ADULTS, IT DOESN'T.

THE UGLY THING IS THE RECENT NEWS THAT CAME OUT WITH PROSTATE CANCER.

HIGH DOSES OF OMEGA-3 FATTY ACID S INCREASES THE RICK OF PROSTATE CANCER BY 70%.

THAT'S THE UGLY PART.

WHAT'S THE MESSAGE TO A LOT OF PEOPLE WATCHING THIS? IF YOU TAKE .5 MILLIGRAM OR 1 GRAM, THAT'S ENOUGH.

TWO PORTIONS OF SALMON A WEEK, THAT'S MORE THAN ENOUGH.

THE PROBLEM IS THAT A LOT OF DOCTORS ON TV PUSH FLAXSEED, FISH OIL, SALMON, MULTIVITAMINS, OMEGA-3 FATTY ACID.

THAT ACCUMULATIVE DOSE IS NOT GOOD.

>> THIS IS THE FIRST TIME AND I HAVE BEEN DOING THIS SHOW FOR MANY YEARS, I NEVER HEARD A BAD THING ABOUT OMEGA-3s AND FISH OIL.

70% INCREASE IN PROSTATE CANCER? WHAT ELSE SHOULD WE KNOW? >> THAT WE TALKED ABOUT, AND I LIKED THAT STUDY AND DAVID THAT STUDY BECAUSE IT WAS WELL DONE.

HERE'S THE ISSUE, OMEGA-3 FATTY ACIDS, THE AMERICAN HEART ASSOCIATION SAYS 1 GRAM A DAY.

TODAY, WE'RE TALKING ABOUT DIMENSIONA.

THERE'S ADVANTAGE WITH OMEGA THREES AND DEPRESSION.

I'M NOT THAT IMPRESSED WITH THIS STUDY BECAUSE IT WAS DONE OVER SIX MONTHS ONLY AND USED RATS OTHER THAEN PEOPLE AND HAD THEM DO PUZZLE SOLVING AND MEMORY.

I'M NOT TOTALLY CONVINCED WE CAN SAY THIS IS SOMETHING THAT'S RELATED TO ALZHEIMER'S.

THERE WAS A STUDY A FEW YEARS AGO THAT SHOWED A 40% REDUCTION IN ALZHEIMER'S IN PEOPLE WHO HAD A LOT OF OMEGA-3s IN THEIR DIET.

I THINK THE JURY IS STILL OUT ON OMEGA-3s, BUT WHAT WE'RE COMING ON IS THIS IDEA, YOU HAVE TO KNOW WHY YOU'RE DOING SOMETHING.

IF YOU EAT FISH, MAYBE IT'S BECAUSE YOU'RE NOT EATING MEAT.

MAYBE IT'S PART OF A HEALTHIER LIFESTYLE.

MAYBE THAT'S WHY WE'RE SEEING SOME OF THE ADVANTAGES OF IT, SO WHAT'S WRONG WITH THAT? YOU EXERCISE, YOU EAT RIGHT, YOU'RE ON THE MEDITERRANEAN DIET WE TALK ABOUT, AND YOU EAT A COUPLE PORTIONS OF FISH A WEEK.

DO IT WITH MODERATION.

>> KEEP POPPING THE FISH OIL? >> DON'T DO IT BECAUSE OMEGA-3 FATTY ACID IN FISH OIL, IT CAN CAUSE WITH COUMADIN AND ANTIPLATE LTS CAUSE MORE BLEEDING.

>> TALK TO YOUR DOCTOR.

>> ABSOLUTELY.

THAT'S GREAT ADVICE TO DEFINITELY HAVE THE DISCUSSION.

>> EXACTLY.

NOW TO TALK ABOUT KIDNEYS AND KIDNEY FAILURE.

KIDNEY FAILURE IS ONE OF THE LEADING CAUSES OF DEATH IN OUR COUNTRY.

AND ACCORDING TO THE CDC, IT'S ACTUALLY KILLED 50,000 PEOPLE IN
