Raw pasta is hard to digest and even harder to absorb the nutrients. Eating a lot of raw pasta can result in gastrointestinal distress problems. However, eating raw pasta is not necessarily too unhealthy, since it not likely that it would result in any fatal health complications.
Raw pasta is known to contain large quantities of phytates and lectins, which are also referred to as anti-nutrients. These damage the intestinal linings, disrupt enzymatic pathways and even cause systemic inflammations. Phytates go on to find minerals like iron and calcium thus making them unavailable for absorption into the bloodstream. It is because of this that someone who eats raw pasta oftentimes can become mineral deficient and even get sick.
