WEBVTT 00:00:00.787 --> 00:00:04.337 Have you ever heard the one about how breastfeeding is free? 00:00:05.071 --> 00:00:06.222 (Laugther) 00:00:06.596 --> 00:00:08.985 Yeah, it's pretty funny 00:00:09.179 --> 00:00:14.308 because it's only free if we don't value women's time and energy. 00:00:15.337 --> 00:00:19.885 Any mother can tell you how much time and energy it takes 00:00:20.024 --> 00:00:21.892 to liquify her body -- 00:00:22.048 --> 00:00:24.696 to literally dissolve herself -- 00:00:24.864 --> 00:00:26.097 (Laughter) 00:00:26.308 --> 00:00:29.187 as she feeds this precious little cannibal. 00:00:29.396 --> 00:00:30.731 (Laughter) 00:00:31.622 --> 00:00:34.150 Milk is why mammals suck. 00:00:35.617 --> 00:00:37.609 At Arizona State University, 00:00:37.781 --> 00:00:39.494 in the comparative lacation lab, 00:00:39.668 --> 00:00:42.327 I decode mothers' milk composition 00:00:42.491 --> 00:00:45.199 to understand its complexity 00:00:45.375 --> 00:00:47.782 and how it influcences infant development. 00:00:48.965 --> 00:00:51.999 The most important thing that I've learned 00:00:52.201 --> 00:00:57.347 is that we do not do enough to support mothers and babies. 00:00:57.996 --> 00:01:00.054 And when we fail mothers and babies, 00:01:00.263 --> 00:01:04.422 we fail everyone who loves mothers and babies: 00:01:04.565 --> 00:01:07.411 the fathers, the partners, the grandparents, the aunties, 00:01:07.606 --> 00:01:11.857 the friends and kin that make our human social networks. 00:01:12.745 --> 00:01:17.413 It's time that we abandon simple solutions and simple slogans, 00:01:17.579 --> 00:01:19.534 and grapple with the nuance. 00:01:19.824 --> 00:01:22.039 I was very fortunate 00:01:22.207 --> 00:01:25.340 to run smack dab into that nuance very early, 00:01:25.543 --> 00:01:28.343 during my first interview with a journalist 00:01:28.534 --> 00:01:30.189 when she asked me, 00:01:30.395 --> 00:01:33.784 "How long should a mother breastfeed her baby?" 00:01:36.277 --> 00:01:40.952 And it was that word "should" that brought me up short 00:01:41.080 --> 00:01:45.506 because I will never tell a woman what she should do with her body. 00:01:47.021 --> 00:01:48.910 Babies survive and thrive 00:01:49.082 --> 00:01:53.082 because their mother's milk is food, medicine and signal. 00:01:53.528 --> 00:01:54.839 For young infants, 00:01:55.004 --> 00:01:56.799 mother's milk is a complete diet 00:01:56.962 --> 00:01:59.351 that provides all the building blocks for their bodies, 00:01:59.540 --> 00:02:00.679 that shapes their brain, 00:02:00.848 --> 00:02:03.008 and fuels all of their activity. 00:02:03.554 --> 00:02:06.072 Mother's milk also feeds the microbes 00:02:06.263 --> 00:02:08.788 that are colonizing the infant's intenstinal tract. 00:02:09.078 --> 00:02:10.606 Mothers aren't just eating for two; 00:02:10.790 --> 00:02:13.120 they're eating for two to the trillions. 00:02:14.747 --> 00:02:19.273 Milk provides immunofactors that help fight pathogens, 00:02:19.493 --> 00:02:24.685 and mother's milk provides hormones that signal to the infant's body. 00:02:25.056 --> 00:02:26.641 But in recent decades, 00:02:26.846 --> 00:02:28.808 we have come to take milk for granted. 00:02:28.972 --> 00:02:31.382 We stopped seeing something in plain sight. 00:02:31.806 --> 00:02:36.844 We began to think of milk as standardized, homogonenized, pasturized, 00:02:36.945 --> 00:02:40.238 packaged, powdered, flavored and formulated. 00:02:40.996 --> 00:02:43.173 We abandoned the milk of human kindness, 00:02:43.350 --> 00:02:45.706 and turned our priorities elsewhere. 00:02:46.755 --> 00:02:50.352 At the National Institutes of Health in Washinton D.C. 00:02:50.544 --> 00:02:52.709 is the National Library of Medicine, 00:02:52.838 --> 00:02:55.474 which contains 25 million articles -- 00:02:55.652 --> 00:03:00.020 the brain trust of life science and biomedical research. 00:03:00.387 --> 00:03:03.712 And we can use key words to search that database, 00:03:03.905 --> 00:03:04.678 and when we do that, 00:03:04.877 --> 00:03:08.886 we discover nearly a million articles about pregnancy, 00:03:09.059 --> 00:03:12.525 but far fewer about breast milk and lactation. 00:03:13.101 --> 00:03:17.713 When we zoom in on the number of articles just investigating breast milk 00:03:17.876 --> 00:03:21.967 we see that we know much more about coffee, wine and tomatoes. 00:03:22.272 --> 00:03:23.529 (Laughter) 00:03:24.795 --> 00:03:28.237 We know over twice as much about erectile dysfunction. 00:03:28.376 --> 00:03:30.341 (Laughter) 00:03:32.471 --> 00:03:34.205 And I'm not saying we shouldn't know about those things -- 00:03:34.387 --> 00:03:35.002 I'm a scientist, 00:03:35.205 --> 00:03:37.288 I think we should know about everything. 00:03:37.673 --> 00:03:40.206 But that we know so much less -- 00:03:40.380 --> 00:03:41.994 (Laughter) 00:03:42.148 --> 00:03:43.247 about breast milk -- 00:03:43.422 --> 00:03:46.034 the first fluid a young mammal is adapted to consume -- 00:03:46.207 --> 00:03:47.986 should make us angry. 00:03:48.266 --> 00:03:52.276 Globally, nine out of 10 women will have at least once child in her lifetime. 00:03:52.810 --> 00:03:57.020 That means that nearly 130 million babies are born each year. 00:03:57.238 --> 00:04:00.350 These mothers and babies deserve our best science. 00:04:00.846 --> 00:04:05.051 Recent research has shown that milk doesn't just grow the body, 00:04:05.226 --> 00:04:08.436 it fuels behavior and shapes neurodevelopment. 00:04:09.058 --> 00:04:13.565 In 2015, researchers discovered that mixture of breast milk 00:04:13.742 --> 00:04:15.159 and baby saliva -- 00:04:15.348 --> 00:04:17.216 specifically, baby saliva -- 00:04:17.386 --> 00:04:20.990 causes a chemical reaction that produces hydrogen peroxide 00:04:21.163 --> 00:04:23.135 that can kill Staff and Salmonella. 00:04:24.184 --> 00:04:26.289 And from humans and other mammal species, 00:04:26.478 --> 00:04:29.859 we're starting to understand that the biological recipe of milk 00:04:29.998 --> 00:04:33.254 can be different when produced for sons or daughters. 00:04:33.889 --> 00:04:37.174 When we reach for donor milk in the neonatal intensive care unit, 00:04:37.405 --> 00:04:39.483 or formula on the store shelf, 00:04:39.612 --> 00:04:41.844 it's nearly one-size-fits-all. 00:04:42.174 --> 00:04:46.440 We aren't thinking about how sons and daughters may grow at different rates 00:04:46.590 --> 00:04:47.681 or different ways, 00:04:47.857 --> 00:04:49.786 and that milk may be a part of that. 00:04:50.504 --> 00:04:52.495 Mothers have gotten the message, 00:04:52.683 --> 00:04:55.871 and the vast majority of mothers intend to breastfeed, 00:04:56.053 --> 00:04:58.575 but many do not reach their breastfeeding goals. 00:04:59.765 --> 00:05:01.750 That is not their failure; 00:05:01.956 --> 00:05:03.322 it's ours. 00:05:04.069 --> 00:05:08.124 Increasingly common medical conditions like obesity, endocrine disorders, 00:05:08.259 --> 00:05:10.287 C-section and pre-term births 00:05:10.441 --> 00:05:13.248 all can disrupt the underlying biology of lactation. 00:05:13.630 --> 00:05:17.249 And many women do not have knowledgable clinical support. 00:05:17.774 --> 00:05:19.306 25 years ago, 00:05:19.476 --> 00:05:23.078 the World Health Organization and Unicef established criteria 00:05:23.248 --> 00:05:25.721 for hospitals to be considered baby friendly -- 00:05:25.858 --> 00:05:29.400 that provide the optimal level of support for mother-infant bonding 00:05:29.580 --> 00:05:31.154 and infant feeding. 00:05:31.714 --> 00:05:35.007 Today, only one-in-five babies in the United States 00:05:35.148 --> 00:05:37.456 is born in a baby-friendly hospital. 00:05:39.408 --> 00:05:40.765 This is a problem, 00:05:40.965 --> 00:05:43.613 because mothers can grapple with many problems 00:05:43.817 --> 00:05:47.343 in the minutes, hours, days and weeks of lactation. 00:05:47.692 --> 00:05:50.217 They can have struggles with establishing latch, 00:05:50.400 --> 00:05:51.209 with pain, 00:05:51.388 --> 00:05:52.425 with milk letdown, 00:05:52.603 --> 00:05:54.281 and perceptions of milk supply. 00:05:55.302 --> 00:05:59.383 These mothers deserve knowledgable clinical staff 00:05:59.813 --> 00:06:01.950 that understand these processes. 00:06:02.808 --> 00:06:06.960 Mothers will call me as they're grappling with these struggles, 00:06:07.166 --> 00:06:09.506 crying with wobbly voices. 00:06:11.646 --> 00:06:13.486 "It's not working. 00:06:13.667 --> 00:06:16.180 This is what I'm supposed to naturally be able to do, 00:06:16.365 --> 00:06:17.794 why is it not working?" 00:06:18.592 --> 00:06:22.054 And just because something is evolutionarliy ancient 00:06:22.227 --> 00:06:25.034 doesn't mean that it's easy or that we're instantly good at it. 00:06:25.873 --> 00:06:28.354 You know what else is evolutionarily ancient? 00:06:28.697 --> 00:06:31.982 (Laughter) 00:06:32.485 --> 00:06:33.709 Sex. 00:06:33.895 --> 00:06:36.695 And nobody expects us to start out being good at it. 00:06:36.929 --> 00:06:38.675 (Laughter) 00:06:39.894 --> 00:06:44.346 Clinicians best deliever quality equitable care 00:06:44.531 --> 00:06:48.433 when they have continuing education about how to best support lactation 00:06:48.596 --> 00:06:49.758 and breastfeeding. 00:06:50.204 --> 00:06:52.218 In order to have that continuing education, 00:06:52.397 --> 00:06:54.230 we need to anchor it to cutting-edge research 00:06:54.382 --> 00:06:58.060 in both the life sciences and the social sciences, 00:06:58.207 --> 00:07:03.837 because we need to recognize that too often historical traumas 00:07:03.986 --> 00:07:05.174 and implicit biases 00:07:05.328 --> 00:07:09.029 sit in the space between a new mother and her clinician. 00:07:09.942 --> 00:07:11.814 The body is political. 00:07:13.036 --> 00:07:16.658 If our breastfeeding support is not intersectional, 00:07:16.829 --> 00:07:19.189 it's not good enough. 00:07:19.521 --> 00:07:22.487 And for moms who have to return for work, 00:07:22.658 --> 00:07:27.398 because countries like the United States do not provide paid parental leave, 00:07:27.564 --> 00:07:31.740 they can have to go back in as short as just a few days after giving birth. 00:07:32.723 --> 00:07:35.932 How do we optimize mother and infant health 00:07:36.128 --> 00:07:39.386 just by messaging about breast milk to moms 00:07:39.561 --> 00:07:42.139 without providing the institutional support 00:07:42.322 --> 00:07:45.261 that facilitates that mother-infant bonding 00:07:45.424 --> 00:07:46.773 to support breastfeeding? 00:07:47.036 --> 00:07:49.069 The answer is we can't. 00:07:51.152 --> 00:07:53.762 I'm talking to you, legistlators, 00:07:53.899 --> 00:07:55.445 and the voters who elect them. 00:07:55.683 --> 00:08:00.334 I'm talking to you, job creators, and collective bargaining units, 00:08:00.470 --> 00:08:01.423 and workers, 00:08:01.635 --> 00:08:02.993 and shareholders. 00:08:03.622 --> 00:08:07.590 We all have a stake in the public health of our community, 00:08:07.766 --> 00:08:10.567 and we all have a role to play in achieving it. 00:08:11.494 --> 00:08:14.671 Breast milk is a part of improving human health. 00:08:15.282 --> 00:08:19.057 In the NICU, when infants are born early or sick or injured, 00:08:19.224 --> 00:08:23.266 milk or bioactive constituents in milk can be critically important. 00:08:23.726 --> 00:08:25.027 Environments or ecologies, 00:08:25.198 --> 00:08:28.227 or communities where there's high risk of infectious disease, 00:08:28.431 --> 00:08:30.820 breastmilk can be incredibly protective. 00:08:31.013 --> 00:08:34.362 Where there are emergencies like storms and earthquakes, 00:08:34.560 --> 00:08:35.906 when the electricity goes out, 00:08:36.089 --> 00:08:37.929 when safe water is not available, 00:08:38.134 --> 00:08:41.236 breast milk can keep babies fed and hydrated. 00:08:42.610 --> 00:08:45.361 And in the context of humanitarian crises, 00:08:45.557 --> 00:08:48.558 like Syrian mothers fleeing war zones, 00:08:48.745 --> 00:08:54.127 the smallest drops can buffer babies from the biggest global challenges. 00:08:55.745 --> 00:09:00.305 But understanding breastmilk is not just about messaging to mothers 00:09:00.462 --> 00:09:02.057 and policy makers. 00:09:02.404 --> 00:09:05.442 It's also about understanding what is important in breastmilk 00:09:05.621 --> 00:09:08.197 so that we can deliver better formulas 00:09:08.411 --> 00:09:12.281 to moms who cannot or do not breastfeed for whatever reason. 00:09:12.681 --> 00:09:14.531 We can all do a better job 00:09:14.711 --> 00:09:17.935 of supporting the diversity of moms raising their babies 00:09:18.098 --> 00:09:20.003 in a diversity of ways. 00:09:21.211 --> 00:09:22.800 As women around the world struggle 00:09:22.989 --> 00:09:26.500 to achieve political, social and economic equality, 00:09:26.678 --> 00:09:29.056 we must reimagine motherhood 00:09:29.226 --> 00:09:34.378 as not the central core aspect of womanhood, 00:09:34.521 --> 00:09:39.474 but one of the many potential facets of what makes women awesome. 00:09:39.640 --> 00:09:41.267 It's time. 00:09:41.786 --> 00:09:43.811 (Applause)
