Question

which is appropriate according to the dri and dietary guidelines for someone on a 1600 - calorie diet?
o a. 53 grams of total fat
o b. 27 grams of total fat
o c. 27 grams of saturated fat
o d. 10 grams of trans - fat

Explanation:

Step1: Calculate the maximum grams of total fat

According to dietary guidelines, fat should provide 20 - 35% of total calories. For a 1600 - calorie diet:

• Lower limit of fat calories: \(0.2\times1600 = 320\) calories
• Upper limit of fat calories: \(0.35\times1600=560\) calories

Since 1 gram of fat provides 9 calories, the range of fat grams is \(\frac{320}{9}\approx35.56\) grams to \(\frac{560}{9}\approx62.22\) grams.

Step2: Analyze saturated and trans - fat

Saturated fat should be less than 10% of total calories. For 1600 calories, saturated fat calories \(<0.1\times1600 = 160\) calories. Since 1 gram of fat (including saturated) provides 9 calories, saturated fat grams \(<\frac{160}{9}\approx17.78\) grams. Trans - fat should be as low as possible, ideally 0.

Answer:

A. 53 grams of total fat
