Is it okay to feed a 4-year-old nilagang baka or sinigang na baboy? Thanks!

NO! not recommended. Bumabara po sa puso ung mga taba ng baka etc. You might wonder baka ung iba nagkakaroon ng heart disease. Red meats such as beef, pork, have more bad saturated fat and cholesterol. Maybe once every 2 weeks is okay but should not be frequent.
