Recommended daily allowance (RDA) is the nutritional requirement and uptake of the food. One has to eat 7 oranges each week so as to meet the requirement.
<h3>What is RDA?</h3>
RDA is the recommended daily allowance that defines the level of the essential nutrients that a person consumes for a healthy lifestyle that is defined by Food and Nutrition so as to meet the required nutrient amount.
Given,
RDA of vitamin C = 60 mg/day
100 gm orange = 70 mg Vitamin C
So for one week, it is calculated as:
7 × 60 = 420 mg
The vitamin C in 100 gm oranges = 0.0007 and 1 oz = 28.3495 grams.
So, 3 oz = 3 × 28.3495 grams = 85048.5 mg
The amount of vitamin C in 85048.5 mg is calculated as:
0.0007 × 85048.5 = 59.53 mg
Number of oranges to be consumed each week = 420 ÷ 59.53 =7
Therefore, 7 oranges must be consumed in a week.
