Consuming raw noodles in small quantities does not usually lead to adverse effects, but if consumed in large quantities it may lead to indigestion. Each 100 grams of raw noodles provides 284 calories and contains 8.3 grams of protein, 61.9 grams of carbohydrates, 0.7 grams of fat, 11 milligrams of calcium and 36 milligrams of iron. Raw noodles do not contain toxic substances and their nutritional composition is similar to that of cooked noodles, but since their proteins are not heat denatured, they are more difficult to digest and absorb. A small amount of raw noodles can provide nutrients to the body and generally does not lead to adverse effects, but if too much is consumed, it can easily lead to indigestion, plus the raw noodles themselves have a poor flavor and are not recommended as a regular food to consume.
