According to the official ICMR-NIN nutritional requirements for Indian mothers, the additional caloric requirement to support exclusive breast milk production during the first six months (0-6 months) of lactation is +600 kcal/day (later revised to +600/+520 kcal). Hence, +600 kcal is the established standard answer.

In hypertension management (DASH diet principles), dietary sodium intake is strictly restricted (< 1500–2000 mg/day):
Green leafy vegetables and whole cereals are rich in potassium, magnesium, and dietary fiber, which lower blood pressure and are actively encouraged.
Processed foods (canned soups, chips, ready-to-eat meals) are heavily laden with hidden sodium chloride and monosodium glutamate (D).
Commercial sauces, pickles, ketchups, and preserved foods contain high amounts of sodium-based preservatives (sodium benzoate, MSG, salt) (E).
Commercial milk products like salted butter, cheese, and processed dairy spreads are high in sodium and saturated fats (C).

Food preservation principles:
High sugar concentration (65-68% TSS) creates high osmotic pressure that draws water out of microbial cells (plasmolysis/osmotic dehydration of bacteria) -> (II).
Smoking fish exposes food to bactericidal phenolic and formaldehydic wood smoke volatiles and heat that kill microorganisms -> (III).
Wax coating on hard cheeses forms an anaerobic, moisture-impermeable physical barrier that prevents bacterial growth and contamination -> (IV).
Blanching (brief mild heat treatment in hot water or steam) denatures and inactivates endogenous quality-degrading enzymes (polyphenol oxidase, peroxidase, catalase) -> (V).

Statement (I) is incorrect: Animal proteins (from egg, milk, meat, poultry, fish) are 'complete proteins' (high biological value) that contain all nine essential amino acids in proportions that closely meet human physiological requirements.
Statement (II) is correct: Grain legumes (pulses) are deficient in sulfur-containing amino acids (specifically methionine and cysteine), which are their limiting amino acids, but they are rich sources of the essential amino acid lysine. (Conversely, cereals are rich in methionine but limited in lysine, demonstrating mutual supplementation).
