Wa'alaikum assalam! Boleh jer minum air kelapa muda masa berpuasa, air kelapa naturally low in sugar and kaya dengan electrolytes, so takde issue dengan glucose readings masa test. Ramai orang pantang sikit jer sebab takut, tapi scientifically okay lang, especially if it's pure air kelapa tanpa tambahan gula. Kalau you worried about the reading, boleh check dengan doctor je, tapi honestly dari experience ramai mum yang minum during puasa fasting okay jer. You're doing great by being careful about what you consume, that shows you really care!
