Final answer:
Chronic alcohol consumption affects the detoxification of dietary ingredients by causing liver and kidney dysfunction, which impairs the excretory system's ability to remove waste substances from the body.
Step-by-step explanation:
Chronic alcohol consumption affects the detoxification of dietary ingredients due to the harmful effects it has on the liver and kidneys. The liver is responsible for breaking down toxic substances in the blood, but excessive alcohol consumption can lead to liver disease. When the liver is not functioning properly, it puts added strain on the kidneys, which can result in kidney dysfunction. This impairs the ability of the excretory system to remove waste substances from the body, including dietary ingredients.
