The immediate postpartum period is recognized as a special time in many societies and is commonly associated with food and work restrictions. The logic of food restrictions during a period of increased energy and protein needs has been challenged, but few data are available to test the impact of these practices on the diets of lactating women. In the eastern Amazon the immediate postpartum period is referred to as resguardo, lasts for 40-41 days and includes food taboos and work restrictions. Taking a biocultural perspective, this paper combines data on the beliefs and attitudes surrounding the practice of resguardo with quantitative data on the actual dietary intakes and activity patterns of a cohort of 23 lactating women followed from birth through 15 months postpartum. This paper addresses three topics: (1) shared ideals regarding resguardo; (2) adherence to food and work restrictions; and (3) the impact of these practices on women's dietary intakes and energy expenditure. The results show that the majority of women adhered to food taboos and work restrictions. During resguardo energy expenditure in physical activity was lower, reducing women's energy needs and allowing them to devote more time to infant care. However, energy intakes were also lower. The reduction in dietary intake was impacted more by work restrictions and the loss of women in subsistence tasks during resguardo than by adherence to food taboos. In addition to altering maternal energetic strategies, resguardo served an important social function by reinforcing bonds and, for young women, marking the transition to womanhood.

Parental Care00:55

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
The Menstrual Cycle01:19

The Menstrual Cycle

The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a uterine...
Long-term Depression01:05

Long-term Depression

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
Ovarian Cycle01:27

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
