Frequently Asked Questions
Q1: Does heating milk reduce its protein content?
No, gentle heating preserves protein quality. However, ultra-high temperatures (UHT) can cause minimal denaturation without significant nutrient loss.
Q2: Can I use protein in milk 250ml for weight gain?
Absolutely—pair milk with calorie‑dense foods like nuts or oats to boost both macros and calories.
Q3: How does milk protein compare to whey powder?
Milk’s protein includes both whey and casein, whereas whey powder isolates the fast-digesting portion only. Both have unique benefits for muscle support.
