Answer: irresponsibility
Step-by-step explanation:
The word "gluttony" in the context of the paragraph most likely means is irresponsibility. Gluttony simply means greed.
From the text, we can infer that some people indulge in unwholesome fast food and think of gratifying a morbid appetite rather than supplying the body with proper nourishment.
This shows irresponsibility with regards to the food that they take.
