Nutrition and Food Sources

Moringa leaves (drumstick leaves) contain exceptionally high levels of carotene (precursor to Vitamin A) compared to common vegetables like lady finger, brinjal, or amaranthus. Moringa is known for its exceptional nutritional profile.

Vegetables are the most comprehensive natural source of vitamins and minerals, providing Vitamin A, C, K, folate, potassium, magnesium, and many others. While cereals provide some B vitamins and minerals provide calcium, vegetables offer the widest variety of micronutrients.

A fact is a statement that is true and can be proven. A fact is true and correct no matter what. An opinion, however, is a statement that holds an element of belief; it tells how someone feels.

Green leafy vegetables like spinach, fenugreek, and amaranth leaves contain significant iron, though pulses (especially with vitamin C) and eggs are also excellent sources. The key is iron bioavailability - plant-based iron is enhanced when consumed with vitamin C-rich foods.

Milling removes the outer bran and germ layers of grains, which actually DECREASES calcium content along with other nutrients like fiber, iron, and B vitamins. The statement that milling increases calcium content is factually incorrect, making it the answer to 'which statement is not correct.' Parboiling, malting, and sprouting do preserve or increase nutrients as stated.

The correct usage of contrary is ‘contrary to’. Rest of the options do not give a sound grammatical structure. Hence (1).

Groundnuts, Sesame, and Mustard are all agricultural products primarily cultivated for the extraction of oil.

Avocados are widely considered one of the most nutrient-dense fruits due to their high content of healthy fats, fiber, vitamins, and minerals. Compared to the other options, they offer a superior nutritional profile.

Scurvy is caused by a deficiency of Vitamin C. Lemons are a rich source of Vitamin C, making them an effective dietary intervention.

Rice is a cereal grain, which belongs to the grass family (Poaceae).

It is used as a supplementary food for humans and animals.
