True or False: MSG, sulfites, and nitrites can adversely affect people with allergies if used beyond approved limits.

1. True

2. False

3. Only true for MSG

4. Only false for nitrites

The correct answer is: True

The statement is true because monosodium glutamate (MSG), sulfites, and nitrites are food additives that can trigger allergic reactions or intolerances in susceptible individuals when used beyond approved limits. Each of these substances has a specific profile for how it can affect individuals with allergies. MSG is known to cause adverse reactions in some people, often referred to as "Chinese restaurant syndrome," which can include symptoms such as headaches, flushing, and other discomforts. This occurs particularly in individuals who are sensitive to it. Sulfites are commonly used as preservatives in dried fruits and other products, and they can cause asthmatic reactions and other allergy-like symptoms in sensitive individuals. Some people may even develop a sulfite allergy, leading to serious health issues if consumed in high amounts. Nitrites, often used in cured meats for preservation and color, can also cause allergic reactions and have been linked to certain health concerns when consumed excessively, especially in processed foods. Overall, these substances must be carefully controlled to ensure that they remain within established safety limits to protect individuals with sensitivities or allergies. Thus, the correct answer reflects the potential health risks associated with these additives when they exceed approved usage levels.
