Final answer:
The acceptable range for lipid intake as per the Food and Nutrition Board is 20% to 35% of daily caloric intake. This fits within the guidelines provided by the American Heart Association for a balanced diet, with an emphasis on the importance of limiting saturated fat intake.
Step-by-step explanation:
The acceptable macronutrient distribution range set by the Food and Nutrition Board for lipids is 20% to 35% of kilocalories. This means that a healthy diet should not exceed 35% of total calorie intake from lipids, which includes fats such as triglycerides, cholesterol, and phospholipids. An example of how this translates into a daily diet could be somebody consuming a 2000 kilocalorie diet; the recommended lipid intake would be a maximum of 700 kilocalories from fats, equal to 77 grams of total fat (since fat has approximately 9 calories per gram).
Based on recommended percentages of daily calories from food groups, we know that saturated fats should account for no more than 10%, and unsaturated fats should make up about 20% of our daily kilocalorie intake for fats. It is also observed from studies that approximately one-third of the calories in an average American diet come from fat, which aligns with the American Heart Association's recommendation of consuming 30% or less of daily calories from fat, with less than 10% from saturated fat.
