There are no health risks to eating too much asparagus, notes LiveScience. However, gas and bad smelling urine are potential side effects from eating large amounts of it. Asparagus can also cause allergic reactions to some people, as stated by WebMD.
Asparagus should not be consumed in high amounts during pregnancy because it may harm hormone balances, as claimed by WebMD. Asparagus is high in folic acid, vitamins B6, A and C, thiamine, and potassium. Since asparagus is a member of the Liliaceae family, people who are sensitive to garlic, leeks, onions or chives may also have an allergy to asparagus.
