Magnesium is an important nutrient that supports immune system functioning and helps protect the body against cardiovascular diseases. Symptoms of magnesium deficiency rarely surface among populations in developed countries, but concern is growing that many people may not have sufficient body stores of this metal. Surveys show that most Americans do not receive a minimum daily requirement of magnesium in their diets.
Magnesium is absorbed from foods by the intestines, before the circulatory system transports it to the body's tissues. Less than one-half of ingested magnesium normally is taken up in this way.
Health issues affecting the digestive tract may impair magnesium absorbance. For example, gastrointestinal disorders such as Crohn's disease can limit magnesium uptake. The kidneys normally limit urinary excretion of magnesium, a function that can help make up for low dietary intake. However, alcohol abuse and certain medications can affect this balance and thereby lead to magnesium depletion.
Symptoms of magnesium deficiency include vomiting, fatigue, and loss of appetite. More severe cases can include symptoms such as muscular cramps, seizures, and coronary abnormalities.
Magnesium insufficiency also can affect the body's ability to absorb other cations, including calcium and potassium, and can lead to other health complications. Good sources of dietary magnesium include leafy green vegetables, potatoes, nuts, and seeds.

According to the passage, what health issue can result from alcohol abuse?

  • A. poor magnesium absorption.
  • B. an impairment of kidney function.
  • C. compromise of the immune system.
  • D. gastrointestinal disorders.
Correct Answer: C

Rationale: The correct answer is C, compromise of the immune system. The passage states that alcohol abuse can weaken the immune system, making individuals more susceptible to infections and illnesses. This compromise of the immune system can lead to various health issues and exacerbate existing conditions. Choices A, B, and D are incorrect based on the passage. While the passage discusses the impact of alcohol abuse on magnesium absorption and kidney function, it does not directly attribute these issues to alcohol abuse. Gastrointestinal disorders are mentioned in relation to magnesium absorption but are not specifically linked to alcohol abuse.
