0:00Carrots have been around for thousands
0:01of years. There are even records of
0:04carrot seeds from as early as 3000 BC.
0:07But the most famous thing about them is
0:09pretty recent.
0:10>> Better have one of these. Best thing in
0:11worldw.
0:13>> Sergeant, you need to eat a few more
0:14carrots to improve your eyesight.
0:16>> Mom, is it true if you eat carrots, you
0:19can see in the dark?
0:20>> I have no idea.
0:22>> I don't believe eating carrots will help
0:23you see in the dark. In fact, in some
0:26conditions like retinitis pigmentotosa,
0:29um, taking too much vitamin A can
0:30actually be toxic.
0:31>> So, why did we grow up thinking this?
0:34And where did the myth come from? Well,
0:36the answer actually takes us back to
0:38World War II with a story of propaganda
0:41and secret British technology.
0:45The humble carrot or dacus kota is a
0:48member of the apaci family along with
0:50parsnips, parsley, dill, fennel, and
0:53other plants that go in delicious soups.
0:56Carrots find their origin in central
0:58Asia with evidence pointing to their
1:00exact birth being in present day
1:01Afghanistan, but they quickly spread
1:03throughout North Africa, Europe, and
1:05Western Asia. In an early book of herbal
1:08medicines written by Padanios
1:10dioscurities in around year 65, he
1:13writes that the carrot seed is good for
1:15ye painful discharge of urine in
1:18potions. He also wrote that carrots were
1:20good for wild animal bites and even
1:22helpful for people trying to conceive.
1:25In fact, it kind of seems like the
1:27ancient Greeks thought carrots were good
1:28for just about everything but eyesight.
1:30And it's in this 7th century manuscript
1:32of Dioscar's book that we have our first
1:34ever image of an orange carrot. Because
1:37for centuries, carrots weren't usually
1:39orange. They were purple, white, yellow,
1:42and other colors of fancy carrots you
1:44see at bougie farmers markets. The
1:47iconic orange carrot that we eat today
1:49wasn't popularized until Dutch farmers
1:51bred them in the 1600s. And some claim
1:54that the orange was chosen to honor
1:56William of Orange. And orange remains an
1:58important color in the Netherlands to
2:00this day.
2:02From then until the 1900s, carrots
2:04slowly became more popular. We can see
2:06them showing up more and more in the
2:08kitchen, but they were mostly fed to
2:10livestock. As recently as a 100 years
2:12ago, the carrot wasn't quite the iconic,
2:14ubiquitous vegetable that it is today.
2:17And then during World War II, that
2:19changed thanks to one ingenious piece of
2:21propaganda.
2:24500 German bombers and messes fighters
2:27roared over the English coast.
2:29>> By November of 1940, London found its
2:32nights filled with terror from the skies
2:34that made sleep above ground impossible.
2:36>> During World War II, the Germans
2:38sustained a bombing campaign in the
2:40United Kingdom called the Blitz. And the
2:42German bomber planes frequently struck
2:44at night. But the British developed a
2:46new secret radar that would help them in
2:48these nighttime raids. It meant that you
2:50were more difficult to detect, but more
2:52importantly, you were able to detect the
2:55the enemy uh more clearly.
2:57>> And there was one pilot who made great
2:59use of this new radar technology, John
3:01Cunningham.
3:02>> He was one of the first pilots to test
3:04this out and he became highly
3:06successful. He'd actually shot down at
3:09least 20 enemy aircraft and probably
3:12more.
3:12>> Overnight, he became a British hero.
3:15But there was a problem. the Royal Air
3:18Force who did not want the Nazis to
3:22recognize that we'd gained this
3:24advantage. They came up with this idea
3:26that if they could secure a wellknown
3:30pilot, Lee could then persuade the
3:34British people, he had this exceptional
3:37night vision because he was very fond of
3:40carrots and he ate many of them. So he
3:43was nicknamed Cats eye cunningham for
3:45his ability to spot bombers at night.
3:47And the British told the newspapers that
3:48his uncanny ability to see in the dark
3:51came from a certain orange vegetable.
3:54>> There's no mention of, you know, this
3:56particular campaign and that it it was
3:58actually having any impact on sort of
4:01Nazi reactions.
4:02>> But it did trick the British at home.
4:05The myth that carrots could help your
4:06eyesight was spreading quickly. Along
4:08with the stories of Catsai Cunningham
4:10that they were feeding the newspapers,
4:11Britain launched the dig for victory
4:13campaign. Because the British had
4:14another vital reason to convince the
4:16population that carrots were good for
4:18them. During the Second World War, as
4:20Britain faced food shortages, the
4:22government encouraged their people to
4:23grow their own food in home gardens. And
4:25with limited space and a difficult
4:27climate, one of the easiest crops to
4:29grow was carrots.
4:31The Ministry of Food put out lots of
4:33carrot based recipes like carrot trile,
4:35carrot fla, and even carrot cigarettes.
4:38And iced carrots on a stick sold at
4:40candy stores to replace lollipops due to
4:42sugar rationing. And they developed
4:44characters aimed at convincing children
4:46to eat carrots like this guy, Dr.
4:48Carrot. Combined with the stories about
4:50cats Cunningham, the myth that carrots
4:52could make you see in the dark was
4:54cemented. Today, the carrot's one of the
4:56most popular vegetables. It's ranked
4:58fourth in the world behind only its old
5:00friend, potato pee. Another piece of
5:02British propaganda that I can't really
5:04get into, but Google potato pee. You're
5:06not going to be disappointed. Speaking
5:08of delicious carrots, this video is
5:10presented by a delicious yogurt,
5:11Stonyfield Organic. For over 40 years,
5:14Stonyfield Organic has been a champion
5:15for truth in our food system. There's a
5:17lot of misinformation out there. That's
5:19why they believe in highquality
5:20ingredients to ensure that what they put
5:22on shelves is the best product for you
5:24and your family. The milk they use comes
5:26from family farms across the country
5:27like Molly Brook Farm and Cabbat,
5:29Vermont. It's USDA organic certified,
5:31which means no pesticides, no
5:33antibiotics, and no growth hormones. So,
5:35when you're on your next grocery run,
5:36consider checking out Stonyfield Organic
5:38Yogurt. It's also important to note that
5:40Stonyfield Organic didn't dictate the
5:42content of the story, but their support
5:44made this tasty reporting possible. Now,
5:46back to carrots. I've heard all kinds of
5:49interesting myths and the interesting
5:52thing about myths that last a long time
5:53is there is a particle of truth to it.
5:57Yes, we do need vitamin A and other
6:00things, keratenoids to see better, to
6:03actually see. I'm not sure they actually
6:05make it better as much as they keep it
6:07from going blind if you don't have
6:09vitamin A. So, it's not so much that
6:11carrots can help you see better, but
6:13people who don't get enough vitamin A do
6:15actually experience some negative
6:16effects to their eyesight.
6:18>> They get night blindness. They stop
6:20being able to see at night, and over
6:22time, they lose even daytime vision. The
6:24vast majority of us get enough vitamins
6:27if you're eating a normal, healthy diet.
6:29>> And the things that are best for your
6:30eye health might have nothing to do with
6:32your diet at all. Multiple pieces of
6:34data have shown us that people who look
6:37at phones a lot, which is 100% of the
6:39population at this point, end up getting
6:42myopio over time. The two ways to
6:44prevent it, and data shows this very
6:46clearly, which is to get about an hour
6:48of sunlight during high sun times, not
6:51look at the sun, just be outside and not
6:54look at any near target. So, if you grew
6:57up believing that carrots were good for
6:58your eyesight or could even make you see
7:00in the dark, then you fell for World War
7:02II British propaganda. But that might
7:04not be such a bad thing cuz carrots
7:06really are good for you. And in that
7:08sense, maybe Dr. Carrot was on to
7:10something.
