Ayurvedacharya Dr. According to Sunil Carpenter, consumption of raisins before going to bed at night is a rampant remedy for increasing the immune system. This can relieve people who are often suffering from problems like cold, cough and fever. The raisins contain rich amounts of nutrients such as protein, fiber, iron, potassium, copper, vitamin B6 and manganese, which help improve acidity, insomnia, bone weakness and eyesight. Eating boiled raisins in milk at night strengthens the bones, increases the light of the eyes and eliminates sleep related problems. In addition, raisins full of fiber are also beneficial to lose weight by keeping the stomach full. The raisins strengthen the immune system due to antioxidant qualities, which protect the body from viruses and bacteria.
