- HELLO AND WELCOME TO OUR SECTION ON VITAMINS.

WE'RE GOING TO BE COVERING WATER SOLUBLE AND FAT

I WANT TO POINT OUT THAT A LOT OF THE INFORMATION

IN YOUR TEXTBOOK IS GOING TO COVER NUTRITIONAL DEFICIENCIES

WE DON'T SEE THAT OFTEN IN THE UNITED STATES.

THEY'RE MOSTLY FOUND IN DEVELOPING COUNTRIES.

BUT EVEN IF YOU'RE NOT DEFICIENT IN A VITAMIN,

DON'T DEVELOP THE DISEASE ASSOCIATED WITH DEFICIENCY,

HAVING LOW LEVELS OF VITAMINS CAN IMPACT YOUR HEALTH.

NOW REMEMBER MICRONUTRIENTS ARE BOTH VITAMINS AND MINERALS.

WATER SOLUBLE VITAMINS ARE VITAMINS C AND B,

WHEREAS THE FAT SOLUBLE VITAMINS ARE A, D, E,

AND K. NOW WHAT I'D LIKE TO DO IS HAVE YOU TAKE A

LOOK AT THIS PICTURE AND THIS IS FROM THE BP OIL SPILL.

BUT YOU CAN SEE HOW OIL IS DIFFERENT FROM THE WATER.

YOU CAN SEE THERE IS A SEPARATION OF THE TWO.

AND THIS REALLY IMPACTS HOW VITAMINS ARE ABSORBED AND

THEN THEY'RE BIO AVAILABILITY OR HOW THEY FUNCTION IN THE BODY,

HOW THEY'RE TRANSPORTED, HOW THEY'RE STORED IN THE BODY.

SO THINK ABOUT THIS PICTURE OR YOU CAN THINK ABOUT

PART IS VERY SEPARATE FROM THE OILY PART.

NOW, OF COURSE, WE LEARNED ABOUT LIPIDS THAT ACT AS EMULSIFIERS,

THAT CAN HELP BIND AND BRING THOSE INTO SOLUTION.

BUT LET'S START WITH OUR WATER SOLUBLE VITAMINS.

VITAMIN C AND ALL THE VITAMINS ARE WATER SOLUBLE.

SO THIS MEANS THAT THEY ARE GOING TO DISSOLVE IN THE WATER.

SO THAT MEANS THEY'RE EASILY ABSORBED AND TRANSPORTED.

SO IT'S VERY EASY FOR THEM TO BE BOTH DIGESTED AND--

EXCUSE ME, ABSORBED AND THEN TRANSPORTED THROUGHOUT THE BODY.

BUT BECAUSE THEY'RE WATER SOLUBLE THEY'RE

NOT GOING TO BE STORED IN ANY SIGNIFICANT QUANTITIES.

AND THIS ALSO MEANS THAT THEY'RE RARELY TOXIC.

NOW THE FAT SOLUBLE VITAMINS, THAT'S A, D, E, AND K,

THESE ARE NOT GOING TO DISSOLVE IN WATER.

BUT YOU ARE NOT CONSUMING ANY FAT WITH THEM,

THE ABSORPTION IS GOING TO BE MUCH LOWER THAN

IT WOULD BE IF YOU WERE CONSUMING THEM WITH FAT.

BECAUSE THEY HAVE THE CAPACITY TO BE STORED,

IN FACT, YOU KNOW, VITAMIN D YOU CAN GET ENOUGH THROUGH

THE SUMMER MONTH AND WE'LL TALK ABOUT THIS IN A LITTLE BIT,

AND I KNOW I'M JUMPING BACK AND FORTH HERE,

THIS IS MOSTLY FROM FORTIFICATION AND SUPPLEMENTS,

AND THEN WHAT WE'RE GOING TO DO IS TALK ABOUT

BUT I'M START WITH VITAMIN K IN THIS SECTION.

SO THE FUNCTIONS OF VITAMIN A INCLUDE FUNCTIONING WITH VISION,

AND THAT BASICALLY MEANS IT'S GOING TO HELP WITH

REPLACING THE BODY LININGS, SUCH AS THE SKIN.

IT ASSISTS WITH THE GROWTH OF BONES AND EVEN THE TEETH.
