Brazos Valley This Morning.
IN THE 1980S…SOME STUDIES
SHOWED THAT
OLEIC ACID WOULD DECREASE BAD
CHOLESTEROL AND INCREASE GOOD
CHOLESTEROL. THE QUESTION THAT
THEN
BEGAN TO BE ASKED WAS WHAT COULD
BE DONE TO
BEEF TO CHANGE FATTY ACID
COMPOSITION…AND
INCREASE THE AMOUNT OF OLEIC
ACID.
STUDY BEGAN WITH A JAPANESE
BREED OF BEEF
CATTLE THAT IS NOTED FOR ITS FAT
MARBLING.
SHEL WINKLEY HAS MORE IN THIS
WEEK'S FROM THE
GROUND UP.
"WE GOT THOSE SAMPLES FROM
JAPAN AND
REALIZED THAT THERE'S EITHER A
GENETIC
COMPONENT OR A PRODUCTION
COMPONENT
IN INCREASING OLEIC ACID BECAUSE
THE BEEF'S
VERY HIGH IN FAT MARBLING, AND
VERY
HIGH IN OLEIC ACID, AND A FEW
YEARS BACK I
TALKED TO A PRODUCER FROM
HOKKAIDO, THE
NORTHERN MOST ISLAND, AND I
ASKED HIM IS IT GENETICS OR IS
IT PRODUCTION AND HE SAID
IT'S ABOUT SIXTY PER CENT
GENETICS, FORTY
PER CENT PRODUCTION, SO YOU HAVE
TO PUT
BOTH TOGETHER. I SAID ALL RIGHT,
SO YOU NEED
CATTLE THAT WILL MARBLE, AND
CATTLE
THAT THEN HAVE THE GENETICS TO
MAKE MORE
OLEIC ACID." STEPHEN SMITH IS A
REGENTS PROFESSOR AND A TEXAS
A&M
AGRILIFE RESEARCH SCIENTIST. "MY
WIFE'S A REGISTERED DIETICIAN
WITH A PHD IN
NUTRITION, AND I SAID, WE'VE
FIGURED OUT HOW
TO PRODUCE BEEF THAT'S REALLY
GOOD FOR YOU,
AND SHE SAID YOU CAN'T SAY THAT.
I SAID SURE I
CAN, IT'S HIGH IN OLEIC ACID.
UNLESS YOU'VE
DONE A HUMAN TRIAL AND ACTUALLY
DEMONSTRATED THAT IT HAS SOME
POSITIVE
HEALTH BENEFITS AND NOT A
NEGATIVE ONE, SHE
SAID YOU CAN'T MAKE THAT CLAIM."
SMITH TOOK HIS WIFE'S ADVICE AND
DID SEVERAL
STUDIES USING MEN AND WOMEN. "IN
THOSE STUDIES, INVARIABLY, WE
SAW THAT
REGULAR GROUND BEEF WASN'T BAD
FOR YOU,
DIDN'T DO ANYTHING BAD, BUT WHEN
YOU
INCREASED THE OLEIC ACID IN THE
GROUND
BEEF BY USING GENETICS , THEY'D
ALL INCREASE
HDL CHOLESTEROL, THE GOOD
CHOLESTEROL, BUT
THE MORE OLEIC ACID THAT YOU HAD
IN THE
BEEF, THE GREATER RESPONSE WE
GOT."
SMITH'S STUDIES FOUND NO
NEGATIVE HEALTH
IMPACTS, SO HE DID INDEED
CONCLUDE THAT
EATING GROUND BEEF THAT'S HIGH
IN OLEIC ACID
DOES HAVE HEALTH BENEFITS. SO
STRIKE A BLOW TO THE
CONVENTIONAL WISDOM
THAT SAYS THE ALL AMERICAN
HAMBURGER
ISN'T GOOD FOR YOU. I'M SHEL
WINKLEY, LOOKING
AT CENTRAL TEXAS AGRICULTURE,
FROM THE
GROUND UP.
