A new study finds that short-term intake of high-fat foods is good for the heart. Researchers artificially induced ischemic heart injury in mice later in the experiment, similar to what happens in a human heart attack. They found that eating high-fat foods for 24 hours, 1 The damage to the heart tissue of the mice at 2 weeks and 2 weeks was 70% lighter than that of the 6-week high-fat food mice and the "vegetarian" mice. The researchers believe that this is because short-term intake of high-fat foods can give the heart muscles more energy and strengthen the ability to resist damage. They believe that the short-term intake of a high-fat diet may protect heart function. Which of the following is true and best supports the conclusion of the problem? ['If the rats are allowed to "eat a day" and then change to "vegan", their heart\'s ability to resist damage is stronger than the rats that "vegan" from the beginning.', 'High-fat foods can enable the body to obtain the substances and energy necessary for activities such as metabolism.', 'Low-density lipoprotein cholesterol contained in high-fat foods is an indispensable substance for the human body.', 'To reduce the risk of heart disease, pay attention to a balanced diet and proper intake of fats and cholesterol.']
