0:00:00.737,0:00:04.627 Have you ever heard the one[br]about how breastfeeding is free? 0:00:05.061,0:00:06.212 (Laugther) 0:00:06.486,0:00:09.055 Yeah, it's pretty funny, 0:00:09.055,0:00:14.474 because it's only free if we don't value[br]women's time and energy. 0:00:15.287,0:00:19.995 Any mother can tell you[br]how much time and energy it takes 0:00:19.995,0:00:22.043 to liquify her body -- 0:00:22.043,0:00:24.876 to literally dissolve herself -- 0:00:24.876,0:00:26.197 (Laughter) 0:00:26.197,0:00:29.416 as she feeds this precious[br]little cannibal. 0:00:29.416,0:00:30.731 (Laughter) 0:00:31.492,0:00:34.480 Milk is why mammals suck. 0:00:35.507,0:00:37.689 At Arizona State University, 0:00:37.689,0:00:39.632 in the Comparative Lactation Lab, 0:00:39.632,0:00:42.431 I decode mothers' milk composition 0:00:42.431,0:00:45.379 to understand its complexity 0:00:45.379,0:00:48.282 and how it influcences infant development. 0:00:48.965,0:00:52.149 The most important thing that I've learned 0:00:52.149,0:00:57.485 is that we do not do enough[br]to support mothers and babies. 0:00:57.846,0:01:00.224 And when we fail mothers and babies, 0:01:00.224,0:01:04.403 we fail everyone who loves[br]mothers and babies: 0:01:04.403,0:01:07.569 the fathers, the partners,[br]the grandparents, the aunties, 0:01:07.569,0:01:12.220 the friends and kin that make[br]our human social networks. 0:01:12.715,0:01:17.483 It's time that we abandon simple[br]solutions and simple slogans, 0:01:17.483,0:01:19.498 and grapple with the nuance. 0:01:20.422,0:01:22.127 I was very fortunate 0:01:22.127,0:01:25.820 to run smack dab into[br]that nuance very early, 0:01:25.820,0:01:28.863 during my first interview[br]with a journalist 0:01:28.863,0:01:30.369 when she asked me, 0:01:30.369,0:01:34.358 "How long should a mother[br]breastfeed her baby?" 0:01:36.167,0:01:41.012 And it was that word "should"[br]that brought me up short, 0:01:41.012,0:01:45.918 because I will never tell a woman[br]what she should do with her body. 0:01:46.941,0:01:48.900 Babies survive and thrive 0:01:48.900,0:01:52.900 because their mother's milk[br]is food, medicine and signal. 0:01:53.408,0:01:54.929 For young infants, 0:01:54.929,0:01:56.854 mother's milk is a complete diet 0:01:56.854,0:01:59.463 that provides all the building[br]blocks for their bodies, 0:01:59.463,0:02:00.812 that shapes their brain, 0:02:00.812,0:02:03.252 and fuels all of their activity. 0:02:03.554,0:02:06.072 Mother's milk also feeds the microbes 0:02:06.072,0:02:08.857 that are colonizing the infant's[br]intenstinal tract. 0:02:09.078,0:02:10.756 Mothers aren't just eating for two, 0:02:10.756,0:02:13.536 they're eating for two to the trillions. 0:02:14.747,0:02:19.273 Milk provides immunofactors[br]that help fight pathogens, 0:02:19.273,0:02:24.465 and mother's milk provides hormones[br]that signal to the infant's body. 0:02:24.956,0:02:26.541 But in recent decades, 0:02:26.541,0:02:28.753 we have come to take milk for granted. 0:02:28.753,0:02:31.483 We stopped seeing[br]something in plain sight. 0:02:31.727,0:02:36.855 We began to think of milk as standardized,[br]homogonenized, pasturized, 0:02:36.855,0:02:40.538 packaged, powdered, flavored[br]and formulated. 0:02:40.836,0:02:43.283 We abandoned the milk[br]of human kindness, 0:02:43.283,0:02:45.799 and turned our priorities elsewhere. 0:02:46.755,0:02:50.352 At the National Institutes of Health[br]in Washinton DC 0:02:50.352,0:02:52.797 is the National Library of Medicine, 0:02:52.797,0:02:55.633 which contains 25 million articles -- 0:02:55.633,0:02:59.890 the brain trust of life science[br]and biomedical research. 0:03:00.207,0:03:03.792 We can use key words[br]to search that database, 0:03:03.792,0:03:04.815 and when we do that, 0:03:04.815,0:03:09.034 we discover nearly a million[br]articles about pregnancy, 0:03:09.034,0:03:12.500 but far fewer about[br]breast milk and lactation. 0:03:12.991,0:03:17.716 When we zoom in on the number of articles[br]just investigating breast milk, 0:03:17.716,0:03:22.217 we see that we know much more[br]about coffee, wine and tomatoes. 0:03:22.217,0:03:23.474 (Laughter) 0:03:24.725,0:03:28.237 We know over twice as much[br]about erectile dysfunction. 0:03:28.237,0:03:30.202 (Laughter) 0:03:32.331,0:03:34.865 I'm not saying we shouldn't[br]know about those things -- 0:03:34.865,0:03:35.872 I'm a scientist, 0:03:35.872,0:03:37.773 I think we should know about everything. 0:03:37.773,0:03:40.206 But that we know so much less -- 0:03:40.206,0:03:41.820 (Laughter) 0:03:41.820,0:03:43.359 about breast milk -- 0:03:43.359,0:03:46.181 the first fluid a young mammal[br]is adapted to consume -- 0:03:46.181,0:03:47.960 should make us angry. 0:03:48.216,0:03:52.226 Globally, nine out of 10 women will[br]have at least once child in her lifetime. 0:03:52.720,0:03:56.930 That means that nearly 130 million[br]babies are born each year. 0:03:57.188,0:04:00.300 These mothers and babies[br]deserve our best science. 0:04:01.271,0:04:05.106 Recent research has shown that milk[br]doesn't just grow the body, 0:04:05.106,0:04:08.436 it fuels behavior and shapes[br]neurodevelopment. 0:04:08.928,0:04:12.195 In 2015, researchers discovered 0:04:12.195,0:04:15.072 that the mixture of breast milk[br]and baby saliva -- 0:04:15.072,0:04:17.230 specifically, baby saliva -- 0:04:17.230,0:04:21.094 causes a chemical reaction[br]that produces hydrogen peroxide 0:04:21.094,0:04:23.276 that can kill staph and salmonella. 0:04:24.074,0:04:26.429 And from humans[br]and other mammal species, 0:04:26.429,0:04:29.810 we're starting to understand[br]that the biological recipe of milk 0:04:29.810,0:04:33.366 can be different when produced[br]for sons or daughters. 0:04:33.779,0:04:37.434 When we reach for donor milk[br]in the neonatal intensive care unit, 0:04:37.434,0:04:39.483 or formula on the store shelf, 0:04:39.483,0:04:42.135 it's nearly one-size-fits-all. 0:04:42.135,0:04:46.401 We aren't thinking about how sons[br]and daughters may grow at different rates, 0:04:46.401,0:04:47.692 or different ways, 0:04:47.692,0:04:49.961 and that milk may be a part of that. 0:04:50.414,0:04:52.535 Mothers have gotten the message, 0:04:52.535,0:04:55.933 and the vast majority of mothers[br]intend to breastfeed, 0:04:55.933,0:04:58.755 but many do not reach[br]their breastfeeding goals. 0:04:59.725,0:05:01.850 That is not their failure; 0:05:01.850,0:05:03.536 it's ours. 0:05:04.069,0:05:08.264 Increasingly common medical conditions[br]like obesity, endocrine disorders, 0:05:08.264,0:05:10.322 C-section and pre-term births 0:05:10.322,0:05:13.129 all can disrupt the underlying[br]biology of lactation. 0:05:13.540,0:05:17.369 And many women do not have[br]knowledgable clinical support. 0:05:17.674,0:05:19.416 25 years ago, 0:05:19.416,0:05:23.138 the World Health Organization[br]and Unicef established criteria 0:05:23.138,0:05:25.761 for hospitals to be[br]considered baby friendly -- 0:05:25.761,0:05:29.503 that provide the optimal level[br]of support for mother-infant bonding 0:05:29.503,0:05:31.277 and infant feeding. 0:05:31.574,0:05:35.147 Today, only one-in-five babies[br]in the United States 0:05:35.148,0:05:37.796 is born in a baby-friendly hospital. 0:05:39.318,0:05:40.895 This is a problem, 0:05:40.895,0:05:43.763 because mothers can grapple[br]with many problems 0:05:43.763,0:05:47.619 in the minutes, hours, days[br]and weeks of lactation. 0:05:47.619,0:05:50.324 They can have struggles[br]with establishing latch, 0:05:50.324,0:05:51.323 with pain, 0:05:51.323,0:05:52.640 with milk letdown, 0:05:52.640,0:05:54.671 and perceptions of milk supply. 0:05:55.232,0:05:59.643 These mothers deserve[br]knowledgable clinical staff 0:05:59.643,0:06:01.980 that understand these processes. 0:06:02.628,0:06:07.070 Mothers will call me as they're[br]grappling with these struggles, 0:06:07.070,0:06:10.210 crying with wobbly voices. 0:06:11.646,0:06:13.656 "It's not working. 0:06:13.656,0:06:16.219 This is what I'm supposed to[br]naturally be able to do, 0:06:16.219,0:06:18.048 why is it not working?" 0:06:18.482,0:06:22.124 And just because something[br]is evolutionarliy ancient 0:06:22.124,0:06:25.431 doesn't mean that it's easy[br]or that we're instantly good at it. 0:06:25.753,0:06:28.474 You know what else[br]is evolutionarily ancient? 0:06:28.697,0:06:31.982 (Laughter) 0:06:32.315,0:06:33.749 Sex. 0:06:33.749,0:06:36.889 And nobody expects us[br]to start out being good at it. 0:06:36.889,0:06:38.635 (Laughter) 0:06:39.894,0:06:44.346 Clinicians best deliver[br]quality equitable care 0:06:44.346,0:06:48.478 when they have continuing education[br]about how to best support lactation 0:06:48.478,0:06:49.860 and breastfeeding. 0:06:50.064,0:06:52.298 In order to have[br]that continuing education, 0:06:52.298,0:06:54.401 we need to anchor it[br]to cutting-edge research 0:06:54.401,0:06:58.150 in both the life sciences[br]and the social sciences, 0:06:58.150,0:06:59.940 because we need to recognize 0:06:59.940,0:07:05.488 that too often historical traumas[br]and implicit biases 0:07:05.488,0:07:09.439 sit in the space between[br]a new mother and her clinician. 0:07:09.842,0:07:12.304 The body is political. 0:07:12.956,0:07:16.708 If our breastfeeding support[br]is not intersectional, 0:07:16.708,0:07:19.068 it's not good enough. 0:07:19.521,0:07:22.487 And for moms who have to return for work, 0:07:22.487,0:07:27.407 because countries like the United States[br]do not provide paid parental leave, 0:07:27.407,0:07:32.023 they can have to go back in as short[br]as just a few days after giving birth. 0:07:32.603,0:07:36.092 How do we optimize mother[br]and infant health 0:07:36.092,0:07:39.450 just by messaging about[br]breast milk to moms 0:07:39.450,0:07:42.238 without providing[br]the institutional support 0:07:42.238,0:07:44.977 that facilitates[br]that mother-infant bonding 0:07:44.977,0:07:46.696 to support breastfeeding? 0:07:46.886,0:07:49.269 The answer is we can't. 0:07:51.152,0:07:53.762 I'm talking to you, legistlators, 0:07:53.762,0:07:55.398 and the voters who elect them. 0:07:55.583,0:08:00.234 I'm talking to you, job creators,[br]and collective bargaining units, 0:08:00.234,0:08:01.507 and workers, 0:08:01.507,0:08:03.135 and shareholders. 0:08:03.522,0:08:07.700 We all have a stake in the public[br]health of our community, 0:08:07.700,0:08:10.841 and we all have a role[br]to play in achieving it. 0:08:11.334,0:08:14.881 Breast milk is a part[br]of improving human health. 0:08:15.282,0:08:19.237 In the NICU, when infants are born[br]early or sick or injured, 0:08:19.237,0:08:23.266 milk or bioactive constituents in milk[br]can be critically important. 0:08:23.546,0:08:25.117 Environments or ecologies, 0:08:25.117,0:08:28.226 or communities where there's[br]high risk of infectious disease, 0:08:28.226,0:08:30.965 breast milk can be incredibly protective. 0:08:30.965,0:08:34.524 Where there are emergencies[br]like storms and earthquakes, 0:08:34.524,0:08:35.990 when the electricity goes out, 0:08:35.990,0:08:38.050 when safe water is not available, 0:08:38.050,0:08:41.152 breast milk can keep babies[br]fed and hydrated. 0:08:42.540,0:08:45.501 And in the context of humanitarian crises, 0:08:45.501,0:08:48.502 like Syrian mothers fleeing war zones, 0:08:48.502,0:08:54.344 the smallest drops can buffer babies[br]from the biggest global challenges. 0:08:55.565,0:09:00.395 But understanding breast milk is not[br]just about messaging to mothers 0:09:00.395,0:09:01.990 and policy makers. 0:09:02.264,0:09:05.532 It's also about understanding[br]what is important in breast milk 0:09:05.532,0:09:08.378 so that we can deliver better formulas 0:09:08.378,0:09:12.248 to moms who cannot or do not[br]breastfeed for whatever reason. 0:09:12.621,0:09:14.651 We can all do a better job 0:09:14.651,0:09:18.045 of supporting the diversity[br]of moms raising their babies 0:09:18.045,0:09:20.260 in a diversity of ways. 0:09:20.951,0:09:22.840 As women around the world struggle 0:09:22.840,0:09:26.631 to achieve political, social[br]and economic equality, 0:09:26.631,0:09:29.009 we must reimagine motherhood 0:09:29.009,0:09:34.421 as not the central,[br]core aspect of womanhood, 0:09:34.421,0:09:39.484 but one of the many potential facets[br]of what make women awesome. 0:09:39.484,0:09:41.111 It's time. 0:09:41.506,0:09:43.531 (Applause)
