Do any of these resonate with you? Then you have to check out Dr Saurabh Sethi’s new Instagram post on ‘5 signs your body needs more nutrition’. In his November 9 post, Dr Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford Universities and asked: “Which of these signs have you noticed recently?”
Check what twitching in eyelids or limbs indicates
He explained these warning signs in the video he posted, and said: “First, brittle nails. This indicates a deficiency of protein and iron in the diet. Second, twitching in the eyelids or the limbs indicates magnesium deficiency, which is critical for transmitting nerve impulses. Third, clicking sounds at the joints. It could be a warning sign of vitamin D3 or calcium deficiency.”
What premature greying of the hair could indicate
Dr Sethi added, “Fourth, premature greying of the hair. This could indicate a deficiency of vitamin B12, which is crucial for RBC production and oxygen transport at the hair follicles. This could also be a sign of copper deficiency, which is responsible for melanin production, imparting colour to your hair. And fifth, easy bruising. This could mean that you’re running short of vitamin C, which is responsible for collagen formation. It could also mean a deficiency of vitamin K1, which helps in blood clotting.”
