Abstract
BACKGROUND EarlyNutrition ( www.project-earlynutrition.eu ) is an international research consortium investigating the effects of early nutrition on metabolic programming. OBJECTIVE To summarize current evidence and standards, recommendations, guidelines, and regulations on nutrition or supplements in lactating women with emphasis placed on long-term health effects in offspring, including cardiovascular disease, hypertension, overweight/obesity, metabolic syndrome, diabetes, or glucose intolerance. METHODS Medline, Embase, selected databases and websites were searched for documents published between 2010 and 2015. RESULTS Thirteen documents met the inclusion criteria. Effects of maternal long-chain polyunsaturated fatty acid (LC-PUFA) supplementation on overweight/obesity or hypertension in offspring were assessed in 10 studies. One study described the effect of maternal vitamin D supplementation on overweight/obesity, and the remaining 2 studies assessed the effects of maternal probiotic/synbiotic supplementation during lactation on overweight/obesity or metabolic syndrome in their infants. Forty-one documents contained dietary recommendations on various macro- and micronutrients for lactating women, but without consideration of our long-term health outcomes in infants. CONCLUSION Literature on nutrition of lactating women and its effect on their infants' later health with respect to metabolic programming outcomes appeared to be scarce, and focused mostly on supplementation of LC-PUFA's. No recent guidelines or recommendations were available, highlighting the significant research gaps regarding this topic.

Obesity and overweight: Impact on maternal and milk microbiome and their role for infant health and nutrition.
Garcia-Mantrana, I, Collado, MC
Molecular nutrition & food research. 2016;(8):1865-75
Abstract
Obesity, particularly in infants, is becoming a significant public health problem that has reached "epidemic" status worldwide. Obese children have an increased risk of developing obesity-related diseases, such as metabolic syndromes and diabetes, as well as increased risk of mortality and adverse health outcomes later in life. Experimental data show that maternal obesity has negative effects on the offspring's health in the short and long term. Increasing evidence suggests a key role for microbiota in host metabolism and energy harvest, providing novel tools for obesity prevention and management. The maternal environment, including nutrition and microbes, influences the likelihood of developing childhood diseases, which may persist and be exacerbated in adulthood. Maternal obesity and weight gain also influence microbiota composition and activity during pregnancy and lactation. They affect microbial diversity in the gut and breast milk. Such microbial changes may be transferred to the offspring during delivery and also during lactation, affecting infant microbial colonisation and immune system maturation. Thus, an adequate nutritional and microbial environment during the peri-natal period may provide a window of opportunity to reduce the risk of obesity and overweight in our infants using targeted strategies aimed at modulating the microbiota during early life.

Persistent Organic Pollutants and Concern Over the Link with Insulin Resistance Related Metabolic Diseases.
Mostafalou, S
Reviews of environmental contamination and toxicology. 2016;:69-89
Abstract
Persistent organic pollutants (POPs) are mostly halogenated compounds tending to persist in the environment, enter into the food chain, and accumulate in fat mass of mammals due to their high lipophilicity. They include some organochlorine pesticides, polychlorinated biphenyls, brominated flame retardants and polycyclic aromatic hydrocarbons. Some of these chemicals were widely used in the past so that their residues can be detected in the human body, though their usage has been banned for years. POPs have been shown to perturb the health of biological systems in different ways evidenced by carcinogenicity and disrupting effects on endocrine, immune, and reproductive systems. There are many epidemiologic and experimental studies on the association of exposure to POPs with insulin resistance and related metabolic disorders like obesity, diabetes, and metabolic syndrome. Inflammation as a known mechanism accompanying insulin resistance has also been shown to arise in insulin target tissues exposed to POPs. This review addresses the breast milk concentration of POPs in different regions of the world, synthesizes the current information on the association of POPs with insulin resistance related metabolic disorders, and discusses the inflammation as an involved mechanism. Considering high prevalence of insulin resistance related metabolic diseases and their relation with POPs, much need is felt regarding international and regional programs to not only limit their production and usage but eliminate these persistent pollutants from the environment.

Infant feeding and obesity risk in the child.
Oddy, WH
Breastfeeding review : professional publication of the Nursing Mothers' Association of Australia. 2012;(2):7-12
Abstract
Early nutrition in infancy may influence later child health outcomes including overweight through 'programming'. Systematic reviews suggest that breastfeeding is associated with a modest reduction in the risk of later overweight and obesity. This commentary explores some of these mechanisms behind this association. Generally breastfed infants are leaner than artificially (formula)-fed infants and behavioural and hormonal mechanisms may explain this difference. The theory is that a high nutrient diet in infancy adversely programs the principal components of the metabolic syndrome in the child (body mass index, blood pressure and blood lipids) by promoting growth acceleration, whereas slower growth benefits later cardiovascular disease and its risk factors. Artificial-feeding stimulates a higher postnatal growth velocity with the adiposity rebound occurring earlier in those children who have greater fatness later, whereas breastfeeding has been shown to promote slower growth. The adverse long-term effects of early growth acceleration emerge as fundamental in later overweight and obesity. The higher protein content of artificial baby milk compared to the lower protein content in breastmilk is responsible for the increased growth rate and adiposity during the influential period of infancy of formula-fed infants. Breastfeeding, on the other hand, has a protective effect on child overweight and obesity by inducing lower plasma insulin levels, thereby decreasing fat storage and preventing excessive early adipocyte development. Plausible biological mechanisms underlying the protective effect of breastfeeding against obesity are based on the unique composition of human milk and the metabolic and physiological responses to human milk.
