Dialogue: 0,0:00:00.00,0:00:02.66,Default,,0000,0000,0000,,"Safest Source of B12"
Dialogue: 0,0:00:03.64,0:00:05.72,Default,,0000,0000,0000,,What’s the best way to get vitamin B12?
Dialogue: 0,0:00:05.72,0:00:08.43,Default,,0000,0000,0000,,Well, B12 is not made by plants;
Dialogue: 0,0:00:08.43,0:00:09.71,Default,,0000,0000,0000,,not made by animals either.
Dialogue: 0,0:00:09.71,0:00:10.80,Default,,0000,0000,0000,,It’s made by certain bacteria,
Dialogue: 0,0:00:10.80,0:00:13.08,Default,,0000,0000,0000,,some of which line the guts of animals,
Dialogue: 0,0:00:13.08,0:00:14.54,Default,,0000,0000,0000,,of which people eat and drink.
Dialogue: 0,0:00:14.54,0:00:16.20,Default,,0000,0000,0000,,But that’s not the best source,
Dialogue: 0,0:00:16.20,0:00:18.80,Default,,0000,0000,0000,,because of the baggage \Nthat comes along with it.
Dialogue: 0,0:00:18.80,0:00:22.53,Default,,0000,0000,0000,,Just like we can’t get the iron in \Nbeef without the saturated fat,
Dialogue: 0,0:00:22.53,0:00:25.24,Default,,0000,0000,0000,,the protein in pork without lard,
Dialogue: 0,0:00:25.24,0:00:28.40,Default,,0000,0000,0000,,the calcium in dairy without hormones;
Dialogue: 0,0:00:28.40,0:00:32.39,Default,,0000,0000,0000,,we can’t get the B12 in animals without \Nalso consuming stuff we don’t want—
Dialogue: 0,0:00:32.39,0:00:33.92,Default,,0000,0000,0000,,like cholesterol.
Dialogue: 0,0:00:33.92,0:00:37.18,Default,,0000,0000,0000,,For example, to get 47 \Nmicrograms of B12 from eggs,
Dialogue: 0,0:00:37.18,0:00:40.31,Default,,0000,0000,0000,,because the absorption is so low,
Dialogue: 0,0:00:40.31,0:00:44.32,Default,,0000,0000,0000,,we’d have to literally eat hundreds\Nof scrambled eggs a day.
Dialogue: 0,0:00:44.32,0:00:47.29,Default,,0000,0000,0000,,200 to 400 eggs a day!
Dialogue: 0,0:00:47.29,0:00:49.22,Default,,0000,0000,0000,,Do you know how much\Ncholesterol that would be?
Dialogue: 0,0:00:49.22,0:00:51.36,Default,,0000,0000,0000,,If you got all your B12 \Nfrom scrambled eggs,
Dialogue: 0,0:00:51.36,0:00:55.09,Default,,0000,0000,0000,,you’d consume 69,000 \Nmilligrams of cholesterol—
Dialogue: 0,0:00:55.09,0:00:58.100,Default,,0000,0000,0000,,practically your entire \Nyear’s worth every day.
Dialogue: 0,0:00:58.100,0:01:01.45,Default,,0000,0000,0000,,So, yes, chickens harbor bacteria;
Dialogue: 0,0:01:01.45,0:01:02.59,Default,,0000,0000,0000,,the bacteria make B12;
Dialogue: 0,0:01:02.59,0:01:04.32,Default,,0000,0000,0000,,some of that B12 \Nmakes it into the chicken,
Dialogue: 0,0:01:04.32,0:01:05.65,Default,,0000,0000,0000,,and then into the egg—
Dialogue: 0,0:01:05.65,0:01:07.100,Default,,0000,0000,0000,,but so does the cholesterol.
Dialogue: 0,0:01:07.100,0:01:11.14,Default,,0000,0000,0000,,There has to be a better way!
Dialogue: 0,0:01:11.14,0:01:14.35,Default,,0000,0000,0000,,Why don’t the bacteria \Nin our colon make B12?
Dialogue: 0,0:01:14.35,0:01:15.46,Default,,0000,0000,0000,,They do, actually.
Dialogue: 0,0:01:15.46,0:01:19.38,Default,,0000,0000,0000,,It’s just too far downstream \Nto be absorbed.
Dialogue: 0,0:01:19.38,0:01:23.59,Default,,0000,0000,0000,,In one of the less appetizing but \Nmore brilliant experiments in the field,
Dialogue: 0,0:01:23.59,0:01:30.69,Default,,0000,0000,0000,,a Dr. Callender delineated that human \Ncolon bacteria make large amounts of B12.
Dialogue: 0,0:01:30.69,0:01:33.03,Default,,0000,0000,0000,,Although the B12 is not \Nabsorbed through the colon,
Dialogue: 0,0:01:33.03,0:01:33.88,Default,,0000,0000,0000,,it is active.
Dialogue: 0,0:01:33.88,0:01:35.14,Default,,0000,0000,0000,,How do we know?
Dialogue: 0,0:01:35.14,0:01:37.66,Default,,0000,0000,0000,,She found some vegan \Nvolunteers with B12 deficiency,
Dialogue: 0,0:01:37.66,0:01:39.39,Default,,0000,0000,0000,,collected their stools for 24 hours,
Dialogue: 0,0:01:39.39,0:01:41.37,Default,,0000,0000,0000,,and then, you guessed it,
Dialogue: 0,0:01:41.37,0:01:42.78,Default,,0000,0000,0000,,bon appetit!
Dialogue: 0,0:01:42.78,0:01:43.53,Default,,0000,0000,0000,,And it worked!
Dialogue: 0,0:01:43.53,0:01:45.30,Default,,0000,0000,0000,,They were cured.
Dialogue: 0,0:01:45.30,0:01:47.77,Default,,0000,0000,0000,,Those are some hardcore vegans.
Dialogue: 0,0:01:47.77,0:01:50.14,Default,,0000,0000,0000,,There has to be a better way!
Dialogue: 0,0:01:50.14,0:01:51.66,Default,,0000,0000,0000,,And thankfully, there is:
Dialogue: 0,0:01:51.66,0:01:53.59,Default,,0000,0000,0000,,fortified foods and supplements.
Dialogue: 0,0:01:53.59,0:01:57.02,Default,,0000,0000,0000,,Not only the safest, but \Nalso the most effective.
Dialogue: 0,0:01:57.02,0:01:59.07,Default,,0000,0000,0000,,In the U.S. Framingham Offspring Study,
Dialogue: 0,0:01:59.07,0:02:05.35,Default,,0000,0000,0000,,one in six meat-eaters between \Nages 26 to 83 were B12-deficient.
Dialogue: 0,0:02:05.35,0:02:08.15,Default,,0000,0000,0000,,The folks with the highest B12 levels
Dialogue: 0,0:02:08.15,0:02:10.22,Default,,0000,0000,0000,,weren’t the ones eating \Nthe most animal products,
Dialogue: 0,0:02:10.22,0:02:12.21,Default,,0000,0000,0000,,but the ones taking supplements,
Dialogue: 0,0:02:12.21,0:02:16.78,Default,,0000,0000,0000,,and eating the most \Nfortified breakfast cereal.
