|According to the World Health Organization (WHO), Nutritional support is an integral part of a comprehensive response to HIV/AIDS. Receiving appropriate nutrition can help improve the health and quality of life of HIV-infected individuals. The current WHO recommendations for the nutrient requirements of people living with HIV/AIDS call for increases in energy over the intake levels recommended for healthy non-HIV-infected individuals of the same age, sex, and level of physical activity. Increased energy metabolism in asymptomatic adults requires 10-15 percent additional energy; this additional energy requirement is 20-30% in symptomatic adults.
Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed
