Dr Shubham Vatsya, a senior gastroenterologist and hepatologist at Fortis, said, "Making egg yolks the villain is...biggest scam run by nutritionists." He said the liver produces most cholesterol, so yolks have minimal impact. Citing a study of 1.5 lakh people, he noted that one egg a day doesn’t raise heart or stroke risk. Yolks improve HDL and offer key nutrients.
