Role of Protein and Amino Acids in Infant and Young Child Nutrition: Considerations for the Development and Delivery of High Quality Complementary Food Supplements.

Prevention of malnutrition in infants and children is multifaceted and requires the following: access to and intake of nutritious food starting at birth with exclusive breastfeeding for the first 6 mo of life, continued breastfeeding in combination with complementary foods from 6-24 mo of age, access to clean drinking water and sanitation, and access to preventive and curative health care (including prenatal). Nutrient-dense complementary foods can improve nutritional status and have long-term benefits; however, in a review of plant-based complementary foods in developing countries, most of them failed to meet many micronutrient requirements. There is need to provide other cost-effective alternatives to increase the quality of the diet during the complementary feeding stage of the lifecycle.

Role of Protein and Amino Acids in Infant and Young Child Nutrition: Protein and Amino Acid Needs and Relationship with Child Growth.

Over a third of all deaths of children under the age of five are linked to undernutrition. At a 90% coverage level, a core group of ten interventions inclusive of infant and young child nutrition could save one million lives of children under 5 y of age (15% of all deaths) (Lancet 2013). The infant and young child nutrition package alone could save over 220,000 lives in children under 5 y of age.

Technological properties and probiotic potential of Lactobacillus fermentum strains isolated from West African fermented millet dough.

Background: Throughout Africa, food fermentations are still driven by indigenous microorganisms which influence the nutritional, organoleptic and safety of the final products. However, for improved safety, consistent quality and beneficial health effects, a trend has emerged which involves the isolation of indigenous strains from traditional fermented products to be used as functional starter cultures. These functional starter cultures possess inherent functional characteristics and can contribute to food quality and safety by offering one or more organoleptic, nutritional, technological or health advantage (probiotics).
