There is no RDA for fiber, but the American Dietic Association recommends 20-35 grams from a variety of fiber-rich foods per day. Most people in the US average only 5-10 grams per day; too much fiber (50+ grams per day) may be unhealthy.

Recommended Daily Intake or Reference Daily Intake.
they are used to limit your intake our serve as a guide to how much intake is taken in
Recommended daily fibre intake is between 20 and 30 grams per day.
Dietary intake refers to your daily ingestion of food and water.
The reference values for nutrient intake used on food labels are typically based on established dietary guidelines, such as the Daily Values (DVs) set by health authorities like the FDA. These values indicate the recommended daily intake of various nutrients for a standard adult diet, often based on a 2,000-calorie daily intake. DVs help consumers understand the nutritional content of food in the context of their overall daily diet. Specific values can vary by nutrient and demographic factors, such as age and sex.
Daily Values are the daily dietary intake standards used for nutrition labeling on foods and dietary supplements.
An adults daily dietary fiber intake should generally fall in the range of 20 to 35 g.
The recommended daily intake of protein for dogs is about 25-30 of their total daily calories.

The Recommended Dietary Allowances (RDAs) are a subgroup of the system of Dietary Reference Intakes. The different DRIs include RDAs, Adequate Intakes (AI), Estimated Energy Requirements (EERs), and Tolerable Upper Intake Levels (UIs). Recommended Dietary Allowance is based on meeting the needs of about 97% of the population in a particular age and gender group. Getting below 70% of the RDA of a nutrient is a cause for concern.
Trans fats are to be avoided for proper dietary measures. The RDA (Recommended Daily Allowance) for trans fats is less than 1 percent of the caloric daily intake
The full form of RDA is Recommended Dietary Allowances. RDA represents the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all healthy individuals in a specific life stage and gender group.
