Final answer:
The statement is true; triglycerides constitute about 98% of dietary fats. These molecules are critical for energy storage and other bodily functions but should be moderated in the diet to maintain heart health.
Step-by-step explanation:
The statement that triglycerides make up about 98% of all the fats in the diet is true. Triglycerides are indeed the most common type of fats found in the diet and in the body’s tissues. Triglycerides provide a major source of energy for the body, particularly during rest and low to moderate intensity physical activities. They are comprised of a glycerol backbone and three fatty acids. Beyond energy storage, they have roles such as assisting in the absorption of fat-soluble vitamins A, D, E, and K, providing insulation to retain body heat, and protecting bones and internal organs.
Dietary triglycerides are critical for a healthy diet but should not exceed 35 percent of total caloric intake. Excess triglycerides can be a concern for heart health, which has led to the popularity of omega-3 fatty acid supplements to help manage triglyceride levels in the blood. However, it is important to remember that these supplements are not substitutes for a balanced diet and regular exercise.
