That is not true, unless the answerer took the term literally, thinking you were asking about a real coma induced by food. (In which case, it is still theoretically possible in extremely rare cases to fall into a coma resulting from symptoms of a food allergy.)
However, the question was about sleepiness after a meal which is commonly known as "Food Coma".
This feeling is usually experienced after consuming a large meal, or a "heavy" meal, but can be felt even after small carb-heavy meals.
It is caused by several factors, including the digestion process suddenly consuming up to 50% of the body's energy level, blood sugar changes due to food consumption as well as hormonal shifts in the brain following a meal. The same hormones that are supposed to trigger the "I'm Full" signal also trigger the "I'm tired, let's sleep!" signal.
In many cases, from a severe head injury but there are many other causes for comas. Also comas can be caused from lack of oxygen to the brain such as if one was to fall unconcious underwater they may slip into a coma.

Any brain damage obtained before the state of coma is what causes clawing hands during a coma. This is what is commonly called a vegetative state.
Anatomic causes of coma are diagnosed from CT (computed tomography ) or MRI (magnetic resonance imaging ) scans.
metabolic causes of coma consist of those conditions that change the chemical environment of the brain, thereby adversely affecting function.

Metabolic causes of coma are diagnosed from blood work and urinalysis to evaluate blood chemistry, drug screen, and blood cell abnormalities that may indicate infection.
