Meat supply many nutrients like iron, protein, magnesium, zinc and fat etc. But calcium is present in only negligible quantity. 

Soybeans are among the richest plant sources of protein, containing approximately 36-56% protein by weight. This is significantly higher than meat (which has high protein but also high fat and water content), green leafy vegetables (which are primarily fiber and water with modest protein), or oranges (which are mainly carbohydrates with minimal protein). Soybeans are a complete protein source, making them particularly valuable in vegetarian diets.

David Morley, a British pediatrician, developed the Growth Chart in the 1960s as a simple tool for monitoring child health in developing countries. The growth chart allows health workers to track a child's weight and height over time, making it easy to identify growth failure early. This simple visual tool revolutionized child health monitoring globally and remains a cornerstone of child health programs today.

Orchitis is the medical term for inflammation of the testes. The suffix '-itis' indicates inflammation, while 'orch-' refers to the testis (from Greek 'orchis'). This condition can be caused by bacterial or viral infections, with mumps being a common viral cause. The other options refer to inflammation of different anatomical sites: peritoneum (peritonitis), skin (dermatitis), and cartilage (chondritis).

The Medical Termination of Pregnancy (MTP) Act was passed by the Indian Parliament in 1971 and came into force in 1972. This landmark legislation legalized abortion in India under specific conditions, marking a significant step forward for women's reproductive rights. The Act was amended in 2002 and 2003 to expand access and update regulations. 1971 represents the year of original passage.

Surat, a major city in Gujarat, experienced a significant plague outbreak in 1994. This was the first major plague epidemic in India since the early 20th century and caused international concern. The outbreak led to massive public health responses and highlighted the importance of urban sanitation and disease surveillance systems. The other cities listed did not experience plague outbreaks in 1994.

Smallpox vaccine, the first successful vaccine to be developed, was introduced by Edward Jenner.

Colostrum is the first milk produced by mammals, including humans, in the initial days after giving birth. It is thick, yellowish, and rich in antibodies, growth factors, and immune cells that provide crucial passive immunity to the newborn. Colostrum is often called 'liquid gold' due to its concentrated nutritional and immunological value. Normal milk production begins several days after birth, while weaning refers to the transition away from milk.

Vision 2020: The Right to Sight was a global initiative launched in 1999 by the World Health Organization (WHO) in partnership with the International Agency for the Prevention of Blindness (IAPB). The goal was to eliminate avoidable blindness by the year 2020. While other UN agencies like UNESCO and UNICEF work in health domains, this specific vision initiative was led and funded primarily by WHO. DANIDA is the Danish development agency, not the primary funder.

Vitamin D is called “kidney hormone”.

In epidemiology, 'bridge population' refers to groups that can transmit infections from high-risk groups to the general population. STD patients are considered a bridge population because sexually transmitted infections can spread from them to their partners who may not be in high-risk groups. This concept is crucial in disease control planning. AIDS patients, cancer patients, and viral fever patients do not typically serve as epidemiological bridge populations in the same way.

Stroke volume is the correct term for the amount of blood ejected by the left ventricle during each heartbeat. In a healthy adult at rest, this is approximately 70-80 mL. Cardiac output is the total blood pumped per minute (stroke volume × heart rate). Ejection fraction is the percentage of blood pumped out relative to the total blood in the ventricle. 'Threshold output' is not a standard cardiac term.

Pellagra is a deficiency disease caused by lack of niacin (vitamin B3) or its amino acid precursor tryptophan. The classic symptoms are known as the '3 Ds': diarrhea, dermatitis, and dementia, with death being the fourth if untreated. Pellagra was historically common in populations dependent on corn-based diets. The other options are deficiencies of different vitamins: folic acid (megaloblastic anemia), vitamin C (scurvy), and thiamine (beriberi).

Byssinosis is specifically an occupational lung disease caused by exposure to cotton, flax, or hemp dust in textile workers. It is not genetic, hormonal, or nutritional - it develops from workplace inhalation of organic dust particles.

The Reproductive and Child Health (RCH) programme was launched in India in 1997 during the Ninth Five-Year Plan. It integrated various maternal and child health services into a comprehensive program.

Trophology is the branch of science that specifically studies nutrition and food science. Mycology studies fungi, phonology studies sound systems in language, and teleology is a philosophical concept about purpose and design in nature.

The National AIDS Control Programme (NACP) was launched in India in 1987, making it one of the earliest national responses to HIV/AIDS globally. Phase I began in 1992, but the program itself was established in 1987.

Dengue fever is transmitted specifically by Aedes mosquitoes, particularly Aedes aegypti. Anopheles mosquitoes transmit malaria, Culex mosquitoes transmit West Nile virus and filariasis, making Aedes the correct answer.

World Health Day is celebrated annually on April 7th to mark the founding of the World Health Organization (WHO) in 1948. Each year focuses on a specific health theme.

The chemical name of the vitamin B12 is cobalamin.

Rice water stool - watery, pale, flecked with mucus resembling rice water - is the classic diagnostic symptom of cholera. It's caused by the cholera toxin producing massive fluid secretion into the intestine.

The mediastinum is the central compartment of the thoracic cavity between the two lungs. It contains the heart, great vessels, trachea, esophagus, and thymus gland. The pleural cavity surrounds individual lungs, while thoracic cavity is the broader term.

Enteric fever is the clinical term for typhoid fever, caused by Salmonella Typhi. It affects the intestines (enteric = relating to the intestine). Measles and mumps are viral diseases, while cholera causes different gastrointestinal symptoms.
