Optimizing body composition with higher muscle and bone mass is crucial for maintaining metabolic activities and preventing various diseases. Poor dietary quality, especially in resource-limited settings, can negatively affect health due to high cereal intake and low animal protein consumption. In addition, deficiencies in vitamin D and calcium are prevalent. Improving diet quality and providing adequate supplementation can improve body composition, enhance overall health, and prevent metabolic diseases in young women in developing countries.
Optimum body composition in terms of higher muscle and bone mass is crucial for balancing metabolic activities for sustainability of healthy human life. Individuals with lesser muscle mass respond poorly to stressed states such as traumatic injury, sepsis and advanced cancers. Most common diseases like obesity, heart disease, cancer and diabetes can be prevented by muscle mass modification. The nutrients like protein, lysine, calcium and vitamin D play a critical role in the maintenance of muscle mass and bone health. Poor dietary protein quality owing to high amounts of cereals and little animal foods have a marked negative impact on health in resource-limited settings. Lysine intake in developing countries is low mainly due to lesser food intake, consumption of cereals as staple diet and processing loss of lysine. Furthermore, lysine intakes have been shown to be marginal in low socio-economic groups which are of even greater concern. Cereal-based diets and cereal-based food subsidy programs offer low quality proteins and pose a risk of quality protein deficiency. Diets lacking in vitamin D contribute to vitamin D deficiency which is prevalent in epidemic proportions in large part of the world. Cereal-based vegetarian diets are responsible for lesser bioaccessibility of calcium as well. For obtaining optimal health, optimal muscle mass should be maintained at a younger age, which can be achieved by improving nutritional quality of diets. Dietary and medicinal supplementation of lysine, calcium and vitamin D may improve the body composition of young adult women in the form of proportionally more muscle mass, bone mass and lesser fat mass, which in turn, may prove helpful in improving general well-being, physical fitness as well as preventing metabolic diseases in developing countries.
