“…Both Kenyan Maasai (Nestel, 1985) and Senegalese Fulani (Benefice et al, 1984) dry season energy intake is higher than in the wet season (Maasai dry season energy intake is 1293 kcallpersodday on Ranch 1, and 1202 kcallpersodday on Ranch 2; wet season intake is 835 kcallpersodday for Ranch 1 and 828 kcallpersodday for Ranch 2; Fulani dry season energy intake is reported as 2619 kcallpersonlday and wet season intake is 2005 kcallpersodday). Although milk, milk products, and livestock could be sold in the wet season for a higher return rate of calories in cereals, pastoralists choose not to do this and drink the milk instead.…”

“…Although wet season data are not available for the Maasai of Tanzania, it is likely that this generality holds for them also. The West African Fulani are the exception to this wet season milk bias, in large part because development efforts have transformed their former dairy enterprise into a commercial meat-producing operation, thus forcing them to sell animals to purchase cereals (Benefice et al, 1984). Cereals form the most important dry season food for all groups except the Turkana.…”

African pastoralists inhabit a variety of environments within tropical arid to semiarid regions. Ecological and cultural factors as well as economic opportunities and constraints influence the amounts and types of foods available. The preferred staple of all pastoral populations is milk from livestock. Pastoral diets are low in energy, but apparently adequate in protein. Growth in children is slow until late adolescence when height approaches the 50th percentile of reference data. Adult pastoralists are correspondingly tall and lean. Maintenance of high human numbers within the economy is a common strategy among a variety of pastoralists. The result is that pastoralists appear to be near the lower threshold of reasonable nutritional status at most times. This occurs despite marked variation in such elements as livestock and human numbers, diet composition, and activity patterns.

“…The possibility of over-consumption among past populations would then have depended on the energy density of the diet, which would have varied enormously according to ecological circumstances, ranging from high values among some hunter-gatherer groups (Speth, 1991), to low values among many agriculturalists (Ulijaszek, 1991). Seasonal overconsumption occurs in most kinds of subsistence economy (Benefice et al 1984;Dugdale & Payne, 1986;de Garine & Koppert, 1988;Galvin et al 1994).…”

Present-day human eating behaviour in industrialised society is characterised by the consumption of high-energy-density diets and often unstructured feeding patterns, largely uncoupled from seasonal cycles of food availability. Broadly similar patterns of feeding are found among advantaged groups in economically-emerging and developing nations. Such patterns of feeding are consistent with the evolutionary ecological understanding of feeding behaviour of hominids ancestral to humans, in that human feeding adaptations are likely to have arisen in the context of resource seasonality in which diet choice for energy-dense and palatable foods would have been selected by way of foraging strategies for the maximisation of energy intake. One hallmark trait of human feeding behaviour, complex control of food availability, emerged with Homo erectus

“…The severe droughts that affected the Sahel in the early 1970s prompted studies on the nutritional status of adults, which provided evidence for precarious mean values and strong seasonal variations in rural populations (Bénéfice et al, 1984;Loutan and Lamotte, 1984).…”

Objective: To describe levels, monthly variations and trends in weight and arm circumference of non-pregnant lactating women living in the Sahel, characterized by one short yearly rainy season (July-October). Methods: A mixed unbalanced cross-sectional longitudinal observational study conducted at 3, 5, 7 and 10 months postpartum among 3869 women living in the Sine area in central Senegal who had brought their infants into dispensaries for immunization from January 1990 to February 1997, and 1-5 consecutive children per woman (26 106 visits). Results: Mean weight was 55.7 kg (s.d.: 7.1), but it varied by 2.5-3.9 kg each year, from high means during the dry season (March-May) to low means at the end of the rainy season (September-November). The prevalence of underweight, overweight and obesity (body mass index (BMI)o18.5, 25-29.9 and 430 kg/m 2 , respectively) was 7.6% (95% confidence interval: 7.3, 7.9), 6.4% (6.1, 6.7) and 0.4% (0.3, 0.4), but varied strongly by season (Po0.0001 for all). Unlike weight, mean arm increased during the early rains, a peak season of agricultural work ( þ 0.10 cm/month (s.d.: 0.6) from June to August vs À0.35 kg/month (s.d.: 1.1) for weight). BMI and arm circumference were positively associated with age (mean: 20.8 vs 22.2 kg/m 2 and 25.3 vs 27.4 cm, at 20-24 and 40-49 years, respectively, Po0.0001 for both). Conclusions: Season was a major determinant of the anthropometric status of rural African women. Negative energy balance reduced body weight from the onset of agricultural labour, while arm circumference increased during early rains, probably due to high physical activity.
