Human milk oligosaccharides (HMOs) in breast milk contribute to the development of the neonatal microbiota and immune system. However, longitudinal studies examining HMO profiles of Chinese mothers remain scarce.
We aimed to analyze HMO profiles, including their composition, concentrations, and changes during lactation, in milk of Chinese mothers.
A total of 822 milk samples from 222 mothers were collected, of which 163 mothers provided single samples. Samples from the remaining 59 mothers were collected on day 3, day 7, and thereafter every 7 or 14 d until day 168. 24 HMOs were studied using high-performance anion-exchange chromatography. Secretor and nonsecretor status were determined based on Lewis blood types and a defined 2'-fucosyllactose (2'-FL) threshold.
Of the 222 mothers, 77% were secretors and 23% were nonsecretors. The longitudinal study involving 59 mothers showed that the total HMOs in secretors were significantly greater than those in nonsecretors during the first 2 wk. Acidic HMOs dec African populations.
Our study showed dynamic changes of 24 HMOs in secretors and nonsecretors during lactation and revealed unique features of these HMO profiles in the milk of Chinese mothers. Interestingly, 2'-FL concentrations in secretors were found to be lower than those of Western populations but higher than those of African populations.
Vitamin A (VA) has been demonstrated to be a regulator of adipose tissue (AT) development in adult obese models. However, little is known about the effect of VA on obesity-associated developmental and metabolic conditions in early life.
We aimed to assess the effects of dietary VA supplementation during suckling and postweaning periods on the adiposity and metabolic health of neonatal and weanling rats from mothers consuming a high-fat diet (HFD).
Pregnant Sprague-Dawley rats were fed a normal-fat diet (NFD; 25% fat;
=2) or an HFD (50% fat;
=2), both with 2.6mg VA/kg. Upon delivery, half of the rat mothers were switched to diets with supplemented VA at 129mg/kg, whereas the other half remained at 2.6mg VA/kg. Four groups of rat pups were designated as NFD, NFD+VA, HFD, and HFD+VA, respectively. At postnatal day (P)14, P25, and P35, pups (
=4 or 3/group) were killed. Body weight (BW), visceral white AT (WAT) mass, brown AT (BAT) mass, uncoupling protein 1 mRNA expression in BAT, serum glucose, lipidlishing a higher RDA of VA for specific populations should be studied further for managing overweight/obesity in early life.
Rates of childhood obesity are higher in American Indian and Alaska Native populations, and food insecurity plays a major role in diet-related disparities. To address this need, local healthcare providers and a local nonprofit launched the Navajo Fruit and Vegetable Prescription (FVRx) Program in 2015. Children up to 6 y of age and their caregivers are enrolled in the 6-mo program by healthcare providers. selleck compound Families attend monthly health coaching sessions where they receive vouchers redeemable for fruits, vegetables, and healthy traditional foods at retailers participating in the FVRx program.
We assessed the impact of a fruit and vegetable prescription program on the health outcomes and behaviors of participating children.
Caregivers completed voluntary surveys to assess food security, fruit and vegetable consumption, hours of sleep, and minutes of physical activity; healthcare providers also measured children's body mass index [BMI (kg/m
)]
score at initiation and completion of the program. We calculated changes in health behaviors, BMI, and food security at the end of the program, compared with baseline values.
A total of 243 Navajo children enrolled in Navajo FVRx between May 2015 and September 2018. Fruit and vegetable consumption significantly increased from 5.2 to 6.8 servings per day between initiation and program completion (
<0.001). The proportion of participant households reporting food insecurity significantly decreased from 82% to 65% (
<0.001). Among children classified as overweight or obese at baseline, 38% achieved a healthy BMI
score at program completion (
<0.001). Sixty-five percent of children were retained in the program.
The Navajo FVRx program improves fruit and vegetable consumption among young children. Children who are obese or overweight may benefit most from the program.

In Canada, few studies have examined how place shapes Indigenous food environments, particularly among Indigenous people living in southern regions of Ontario.
This paper examines and compares circumstances of food insecurity that impact food access and dietary quality between reserve-based and urban-based Indigenous peoples in southwestern Ontario.
This study used a community-based survey containing a culturally adapted food-frequency questionnaire and cross-sectional study design to measure food insecurity, food access, and dietary quality among Indigenous respondents living in urban (
=130) and reserve-based (
=99) contexts in southwestern Ontario.
Rates of food insecurity are high in both geographies (55% and 35% among urban- and reserve-based respondents, respectively). Urban-based participants were 6 times more likely than those living on-reserve to report 3 different measures of food insecurity. Urban respondents reported income to be a significant barrier to food access, while for reserve-baPolicies, social movements, and research agendas that aim to improve Indigenous food security must be governed and defined by Indigenous people themselves. Indigenous food environments constitute political, social, and cultural dimensions that are infinitely place based.
Biofortification of staple crops has the potential to increase nutrient intakes and improve health outcomes. Despite program data on the number of farming households reached with and growing biofortified crops, information on the coverage of biofortified foods in the general population is often lacking. Such information is needed to ascertain potential for impact and identify bottlenecks to parts of the impact pathway.
We aimed to develop and test methods and indicators for assessing household coverage of biofortified foods.
To assess biofortification programs, 5 indicators of population-wide household coverage were developed, building on approaches previously used to assess large-scale food fortification programs. These were
) consumption of the food;
) awareness of the biofortified food;
) availability of the biofortified food;
) consumption of the biofortified food (ever); and
) consumption of the biofortified food (current). To ensure that the indicators are applicable to different settings they were tested in a cross-sectional household-based cluster survey in rural and peri-urban areas in Musanze District, Rwanda where planting materials for iron-biofortified beans (IBs) and orange-fleshed sweet potatoes (OFSPs) were delivered.
