of the, the you are what you eat, each cell and your body is made from molecules taken from broken down food. and it's also the source of the energy that keeps you alive. but eating is about more than just nutrients. food is also culture. what we eat has a lot to do with where we come from and the groups we belong to however, stories about food and about who want how and why we'd like to. we can also spread racist stereotypes that topic and much more coming up on dw science show. welcome to tomorrow. today. there is

absolutely no way in the world that black folks only express how people are making decisions about what they're eating. a lot of times and we think about the foods of especially people i folks, we often point to, oh, they're just eating some food. and so the decisions are essentially and according to the narrative and sleep africans in the americas, were only given scraps to eat. the part of a pig that white didn't want what's called awful. yours snouts tales and enters. the story goes that the enslaved people often use hot spices and sugar to make these parts tasty or, or deep fried, done. this is like that still exist today, but they're generally viewed as bad for your health and belong to a causing color for referred to as sofas. we have eaten

a variety of food. so that whole scraps, narrative is one that really capture to sort of 18 hundreds to 18. 65 at the end of enslavement. probably a traveler's account that solved black folks eating also, or the leftovers or the in trails that absolutely is not the whole of african and african american diet. psyche williams force and wrote a book entitled, eating while black. she's a professor of american studies at the university of maryland. when you have people who are repeat those narratives without knowing the history, you repeat the, the stereotype. another stereotype is that black people loved to eat watermelon and chicken back in 2008. when for rock,

obama was 1st elected us president, a caricature circulated online at the white house, with a huge watermelon patch on the front lawn. there was nothing to do about it, it was absolutely a racist, true. its roots can be found and the post slavery era in the us when some black people sold watermelons to earn money. a slice resembles a wide smile, which is how black people were often for trade. always grinning, always happy, always wonderfully delighted to be in servitude to point folks. we were accused of being watermelon. darkies, shrieking, stealing darkies. that narrative goes all the way back to enslavement when we were often accused of stealing the chickens. but stereotypes, the size of another discussion is going on. statistics show that black people in

the us are more likely to be over weight, and they suffer from heart disease and diabetes. more often than whites are, latinos and unhealthy diet is usually blaine, one rich in foods, high and fat, and sugar like sol, food, more fast food. yeah, i think one of the things that motivated me to do this research that was this disquiet this conversation about health disparities right? sociologist joseph includes the junior, wrote his dissertation on the black population and jackson, mississippi. and i wanted to know how black people up and now the social economic letter and make decisions about what they i started with people who are homeless. i spent all my days with them. i think what they age. i only age when they a and then after 3 and a half months through connections that i made, i moved up to people who are in poverty to 90. i had 2 children at the time,

has 3 children. now. what i did was just spend time with and i me and start to see what social structures she's experiencing. and then after 3 and a half months i moved up again to to the lower middle class. there was a family that had moved from washington dc to jackson, mississippi, and i moved up again up a middle class. i sort of worked as a paralegal for a lawyer. a lady paralegal is too strong of a word hash, so to help her out in our office a little bit. if we think about the health conditions of black folks as a result of the or individual decision making, i think that's misplaced. if we think about that, most of is just continuing things that happen in the past. i think that's also misplaced. the term food deserts is often used to describe areas where there's not enough healthy food available many times where socially disadvantaged people that were supermarkets offering fresh produce are far away. the

scenario often goes hand in hand with an over supply of cheap, unhealthy offerings from fast food restaurants such as that description apply to where people liked the non need a single mother. man. if we look at the ninety's put available to you by just drawing a circle around her address and seeing what kinds of grocery stores available or i don't think we will capture as much. this includes thinking about how she gets housing and include how she thinks about getting the healthcare transportation. i think for me, food availability includes all of those things and we're able to think about her food, what's what, what she has access to as being related to these other structures. i think it gives us a lot more analytical good back to the topic of soul food, which doesn't just include ingredients like meat, fat, and sugar,

but often also plant face to components like sweet potatoes, beans, k o, window crack foods, popular among foodies today because they're considered healthy it's a variety of foods that in combination would be most familiar to anyone who has southern group, but also an african american community. we helped to build the cuisine and the culinary legacies of the united states of america and globally. there's absolutely no way we survive off of merely craft. please don't reiterate the single store. one ingredient, commented cuisines, across the globe, potatoes in south america. the ink has cultivated different types of the important staple food, filling and vitamin rich tuber traveled from there to europe. with the spanish can

case the doors and the 16th century. today, there are thousands of varieties with a wide range of properties. however, only a fraction are approved for commercial cultivation. what happens when authorization expires for one popular variety in germany, it's almost spelled the end. then farmers pushed back of 40 years ago after a cost and ellen bag took over his parents farm in germany. he switched to organic production and the family business began focusing on potatoes. today. he's a well known specialist and the cultivation and preservation of old varieties of the tuber. 60 so far hellen bag fights for potato diversity. trying to preserve, for instance, the popular linda variety, which was taken off the market gardens. what music is gone going to suddenly we were no longer supposed to grow, don't get the breeder who owned the rights withdrew and subsequent talks went

nowhere could. so they said we should plant new variety, he says they'd be better and we said, but linda is great. the new varieties can't touch it as please come to des moines with money from the legal battle to get the linda a variety of re approved last it's 5 years constant. ellen vegas on happy the situation. even the roads gather some food asides. what we, who decides what we grow as farmers come, that can't happen. otherwise we're just serving the food industry. let's see. the potato farmer views with suspicion decisions made in brussels. we're new, you seed regulations are being negotiated. the law is 1st draft revealed how much influence the seed industry has. he says that the aim is to force out independent plant breeders to not be able to cut me off much more bureaucracy and higher expenses for smaller breeders who won't be able to cope. and technical prerequisites to forcing selection pressure among breeders,

the small ones will give up, the large ones will increasingly take over the market. and that won't be good for either the seed farmers or consumers for the difficulties of the u. n's food and agriculture organization has long emphasized the importance of preserving old varieties. they are often more resistant to extreme weather conditions, diseases or insect passed. so they could play an important role in b adaptation of agriculture to to climate prices. magdalena plead represented the austrian organization caution. noah in brussels for a year. she observed and consulted during negotiations on the new seed regulations . yes. get get out of that. it's all about what will end up on our plates in the future, whether we prioritize taste, health and diversity, or instead place the future of our food supply in the hands of a few corporation. the l in the hands of vinegar concerning the per austrian

association has an archive that stocks around $5500.00 varieties of vegetables, fruit grains, and legumes. their seeds are available to gardeners and farmers on request it's exports were also alarms. last year, when the 1st draft of the you commission's new seed regulation was published. although everyone is talking about diversity in agriculture, it seems like it will achieve the opposite. the scene agro chemical companies that dominate the seed market and also the past deciding market and both are in the same hands and it seems now they're doing everything they can to get diversity out of c . los, i'd like to put the thing in the draft would have prohibited the transfer and exchange of seeds from old varieties to farmers. only private individuals could have received them even public gene banks would no longer have been allowed to distribute seeds, their pride of farmers to sell, or even just swap their own seeds with other farmers would also event against the

law. this would have had serious consequences for commercial farmers like constant ellen back who rely on diversity defense. good. it'd be a scandal and destroy jobs, free trade, food and seeds. it'd be a blatant monopoly of the industry, which would then determine worldwide what we're allowed to do. that, but if that happened, i would want to be a farmer anymore. they did tell me that nickel bring over 50 percent of all seed production worldwide is in the hands of just for companies. although the market for old varieties is negligible, those companies are competition from seeds for varieties that can't be registered as perhaps they want to adapt agriculture to climate change with genetic engineering rather than through breeding on both sides. you, simon, but seeds from resistant varieties are able to adapt decline medic, conditions to social conditions and so they actually have super powers and just

pushing these characteristics that already exist outside as part of this debate about to do that. if you do it 10 brussels, the industry has a host of lobbyists trying to obstruct and welcome competition. but the parliaments environment committee has backs the idea of c diversity. it's agriculture committee has also confirmed and fund conditional right to seat access for farmers. the restrictions were removed from the draft and the parliament adopted an amended version. germany's farmers association is welcome to the release of seeds from old varieties and recognizes the danger that corporations can seek to impose patented seeds on farmers and one apology because you're all set in mind. monopolies are always a problem for agriculture in don't. however, we're in a better situation in germany than in other places. we have a broad range of medium sized readers here that don't rely on patterns. all

structures are diverse and there are specialists. we want to preserve that and we have to create the conditions to do so. with that from somebody false assumptions. magdalena plead or is organization breed the sigh of relief. for now at least the you parliament's decision safeguards the right of farmers to exchange seats. however, the industry lobby did prevail in one area, essential for saving, traditional and local varieties bureaucracy. it seems besides hippe, okay, and, and worst case scenario, small growers focused on diversity could face more red tape and large corporations . if they offer a range of varieties, they could be overwhelmed by bureaucracy and forced out of the market and marketing . a final decision on the future of seeds will be made in brussels in 2025. but industrial agriculture continues to threaten the diversity that will be urgently needed in the future. small scale producers of old varieties like cost and

ellen bag, say the battle is far from over. because what is right now it's your charity. do you have a science question? then send it to us as a video, text or voice mail. if we answer it in the show, you'll receive a little surprises. the thank you. go on. just ask the this time the question comes from santa king in zambia. the why don't fish sing in water? many fish can float in one place without moving their sens much, and the ability is all down to their swim bladders. it's an oregon located in their trunks. a kind of sac filled with gas. without one, a fish would sink to the bottom like

a stove. that's because their bodies are dense or tense, heavier than the surrounding water. without a swim bladder, they'd have to constantly exert themselves to remain in the same place and a water called out. that'd be strenuous to swim. bladder allows a fish to equalize its weight without if the surrounding water. every 10 meters water pressure increases by one kilogram per square centimeter. if the fish swims up it's swim, bladder expands as the pressure of the water column above its balls. so the fish grows more buoyant to keep from rising even higher. it has to release some gas to compensate this. on the other hand, a fish swims deeper. the water pressure acting on it rises compressing this when bladder then must force more gas into the oregon in order to achieve neutral buoyancy with its surroundings. the principal works in the same way as a boy and see compensator by pumping air into

a vast or releasing its divers can also float effortlessly at different depths. the swim bladder also serves to stabilize fish in the water. those that have problems with their swim bladder is often seen and balanced. swim chaotically or hang upside down. menu caught a legend as fish like raise and sharks have to remain in constant motion to avoid sinking to the bottom. instead of a swim bladder, they have light skeletons and very large livers that store lots of fat. because fat is also lighter than water that helps keep them boy and the bottom dwelling fish like flat fish and more a heels also get by without swim bladders. that's because they don't have to adjust to changes in water pressure the, the oceans are home to many fascinating organisms. the deep sea in particular, is

a real treasure trove, not only of rear plants and animals, but also of valuable raw materials. manganese nodules found there, for example, contain metals urgently needed for the transition to sustainable energy and see, we carl's and shellfish contain active ingredients that could be repurposed as can through drugs or antibiotics. but is it right to just grab all the marine treasure? we can find a treasure hunt on the north sea coast with the search turn up anything valuable today? tyesha and mo hope so it's best if you find a ring or some gold jewelry with coins would also be cool. and we also clean up and take all the bottle caps and other stuff back with us. no matter

what the treasure hunters find, the search is always exciting. the, the depths of the world's oceans. how's the afford beyond price? much remains unexplored, but could one day prove very useful in fields like medicine. for instance, there's fast potential. we see it as a treasure waiting to be discovered. there's a huge range of organisms in the oceans and overall much higher diversity, then auto land data to us online, at the sinking bag society in frankfort marines. who ology is one area of research that for a year, a known species are discovered and any of them could inspire new medicines. the tropical mangrove, c squared, for example, provided the active ingredient for a novel cancer drugs. the potential is enormous, promising new compounds are constantly being added to a growing list for them. so gums adult and despise one child example that's been in

the limelight. recently. as the active ingredient and rim desert video empties it was originally isolated from the horn and silica spines in the 1950s. but i sent a note from the guy on the drug games, same when it proved effective against cove is 19 car off and see we have had millions of years to develop defense mechanisms against an amazing disease. and we can put those mechanisms to good use compounds they produce can, for example, inhibit inflammation, have an anti microbial effect or protect nerve cells. these title mudflats are also a unique habitat. how's the treasure hunt going? most as you just have to be patient with the metal detectors, the 2 searchers are able to detect metallic objects up to half a meter down on the other side of the world and the depths

of the pacific, the different treasure is storing, desires, 4000 meters, beneath the surface, primordial lumps cover the sea bed. manganese nodules could provide industry with some urgently needed resources. there's one guy that's going to have a tied in a to some manganese nodule. habitat in the deep sea is special because they contain metals. we need for the energy transition of it and mainly cobalt and copper. and nicole are fine but also list the young bicycle for and the crew flies to whom valid? so i'm in there. um and then there's also the very specific costs in terms of these nodules provide. they are more guides towing, which is special funnel on the city about that without mind. and he has not jewels wouldn't exist in montgomery knowing got his help habitat for extraordinary creatures. one that our hunger for raw materials could completely destroy with unforeseeable consequences. studies show that mining the sea bed leaves the massive

stars, deep sea echo systems struggle to recover. and the resource is far from inexhaustible. you've actually, i'm really made a grow just a few millimeters in a 1000000 years. so a nodule, the size of my hand is between 5 and 10000000 years old. its fossil raw material, just like oil and gas, is vic when it's gone, but it'll take millions of years to grow back. and the specific you have a task for the phone of the lives on us, not just the stuff that grows on it as the nodules are also a habitat for mobile fod out. that'll also be gone. for millions of years to they going out. there are still no clear regulations for extracting vol materials from the deep sea doubts are growing as to whether the underwater destruction is worth it. mining nodules would only be profitable if prices for metals rise and no

other substitutes are found. done present, inclined by for what at the end of the day is such a small contribution to the supply of raw materials to cause such major and truly long term damage. i don't think that's responsible for those, for so are some treasures better left undisturbed. the finally, the detectors sounds the alarm, but it can't tell whether a metal is valuable or not. that's part of what makes the hobbies so exciting. interesting. just another poll tab, this time. one positive side effect of the hobby is that the seekers also collect any metal waste. they fine for recycling marines while they're just tools. and usually it is on a completely different kind of treasure hunt. somebody's concern is put the on his

expeditions, clear finds new marine organisms every day. sometimes their tiny like these pieces of coral does this sort of stick with the show. that's the greatest treasure for me . that in the oceans of which, by the way, cover most of our planet with 71 percent of our surfaces, water. and we're actually the blue planet and not planet ours. and then we depend on the oceans. but we still know so little about the time you get seen and every time i go out there i find new species and which is really satisfying, just to see how much our existence depends on the diversity of life. and the ocean is growing increasingly clear. it affects food with how materials are cycled climate, practically every fundamental process on the planet. nothing works without the oceans and their inhabitants not,

not put 101599 percent of the bio diversity on our planet is invertebrates and they make up the entire echo system on without them the whole system would simply kalauia wasn't able to just as team of columbia and animals like crowds, snails and corals. those are the true treasures of the sea back to mow and ice looking for a more mundane sort of treasure. 8 hours after their search began, low finally strikes page arch, or ring, and it even fits aisha. it has to be checked against loss property claims 1st, but it was still a nice end to the days. treasure hunt because finding treasure can make you happier to knowing. that wraps things up. thanks for watching and see you again next time on tomorrow. today. bye for now. well

the,

every morning i go to my grandma, i don't know, so i know i'm off the medicine. so you with this property. now we're going to go to my university. this is my car, this is our school. otherwise you have 7 years. what does that like to grow up in europe to young and european euro? my now on the off the same road, my. here's the brave ramos and that would be for go because they

the adoption of the nazis direct to enter room activists. tell the tale of 2 heroic lines. the same in 30 minutes, d w. the doctors. why does this? because now i'm leaving the new host. join us for an exciting explanation of blogs and everything in between. this is a video and audio production, 5 d,

w. i hope video will tune in about half of what did you do before i played tennis. survived the ocean bits. thanks to music. he was the nazis favorite conductor. positions under the swastika, a documentary about the sounds of power and inspiring story about survival. music in nazi germany, watch now on youtube dw documentary, the last presidential election coverage 2024 on dw. we addressed the pivotal issue as of the 2nd. asking the questions of metal to motors and latino to other fastest growing demographic groups in the united states. but historically that boat are turned on has been known, so which interest will motivate people to vote the air and muslims. those are important for both candidates, especially when states like michigan to how we would affect the outcome. because it

actually by the presidential election, 2024 watts, the whole coverage on the this is the w news, and these are top stories. king philippe and queen latifah of spain have cut short a visit to the flood ravaged eastern province of valencia. enraged by late warnings and delayed assistance in spain's worst flash floating in decades, furious crowds hurled mud and insults at the royals. the emergency campaign is now switching to a recovery effort as hopes of finding survivors save carmella harris and donald trump had been making their final.
