【街市健身學】營養師教你街市慳錢增肌（附爆肌餐）

Nutrition Point's founder, Jim Lau, advises that individuals can build muscle affordably by sourcing high-protein foods directly from local markets, which can be more cost-effective than buying protein powder. For example, a $7 block of tofu provides one-third of daily protein and contains soy isoflavones that accelerate muscle recovery. Other budget-friendly options include two large chicken breasts for $25, offering more protein than 1.5 cans of tuna, and beef shank, which contains three times the iron of spinach, making it beneficial for intense workouts.
