Those who are sensitive to monosodium glutamate or trying to avoid it in their food should also be familiar with disodium guanylate. While this food additive doesn't have the same potential adverse effects, it's found in many of the same foods, so it's a good indicator that a food may contain MSG.

Whether a dull ache or a splitting pain, frequent headaches can put a damper on your day-to-day activities.
