Protica Nutritional Research
America’s focus on nutritious eating began to receive general attention in the 1940s when President Roosevelt introduced the RDA, or advisable Daily Allowance (RDA) model. This model, which took on the shape of a pyramid in the 1980s (and hence now goes by the term “food pyramid”), has gone through a number of iterations since its inception more than 60 years ago[i].
This change and evolution of the RDA model is, in many respects, a positive step. It demonstrates that, just as America’s information on diet and nutrition is advancing, so too are the models that guide its eating habits. In fact, the USDA itself has definite to update the term and now refers to “RDI’s” (“Reference Daily Intake”) instead of RDA’s.
However, undermining whatsoever of this constructive change is the fact that galore Americans are increasingly confused over what, how, and when to eat. A survey conducted by the USDA in 1996 verified this fact when 40% of respondents united strongly with the statement that “there are so galore recommendations about well-preserved ways to eat, it’s hard to know what to believe”[ii].
One of the most grave expressions of this growing dietary confusion has to do with a concept called the regular Value, or “DV”. Introduced by the USDA in the 1990s, the DV is a dietary numerical reference that is supposed to allow people to make healthy eating choices[iii].
The unemotional idea behind the DV, which is expressed as a percentage, is that it provides a very important piece of information. The DV informs consumers how much of a nutrient they are getting from a particular food item. For example, if the DV label on a can of beans declares that it represents “10% of the DV for fat”, then consumers can keep track of that number to know if, throughout the day, how much greasy they are eating

However, cardinal does not have to be a mathematician or a dietician to see that the preceding idea begs a significant question: is this10% of the DV for greasy “good” or is it “bad”? In other words, should a consumer choose this source of fat because it represents a good source of fat, or avoid it for the different reason?
It is this question that has caused so much confusion among health-conscious consumers. It has caused specific anxiety among those who are wisely ensuring that they eat the advisable daily allowance for protein.
The importance of protein in diet cannot be understated. It is not simply an essential macronutrient for athletes, such as bodybuilders and runners. Protein is important for life itself, regardless of mobility or athleticism. Among other essential functions, protein maintains and repairs muscle tissue, aids digestion, regulates chemicals, manages hormones, and produces enzymes[iv]. In extreme cases, a dangerous lack of protein actually leads to a condition called Kwashiorkor, where the body cannibalizes itself

Trying to determine the right amount of protein – as expressed in terms of DV% -- has been a difficult challenge for most eaters. Unfortunately, as a result of this confusion, some consumers have not been eating high quality protein. This is because the DV number is simply not enough information upon which they can make healthy protein eating decisions.
The missing number in the DV equation is the Reference Daily Intake (RDI) level. The RDI for protein is, generally, 50 grams per day. Consumers can take the number of total grams of protein in a product, and divide it by this RDI for protein to determine what the “optimum” DV number should be.
For example, if a product offers 25 grams of protein, and the RDI is 50 grams per day, then the product’s “optimum” DV will be 50%. Therefore, the figure “50%” should appear on the product’s labeling. If the number is lower than 50%, the consumers instantly know that it is not an optimum source of protein.
Finding high superior sources for unexpendable micronutrients like protein (among others) is a challenge that should not be difficult, but it is, because whatsoever food makers do not want to educate consumers on how to detect high quality from low quality. This is particularly hapless in the health and nutrition food industry, where cardinal would expect manufacturers strive for higher quality nutrition. Regrettably, this is not always the case.
However, that is not reason to despair. Rather, it just as untold reason to support companies that are making the effort to ensure that their products reflect only high superior DV levels, and a concurrent effort to educate the public on how to determine best DV.
[1] The FDA is broad that the DV concept is not intended to matrilineal people on how much they should eat. In this example, the eater should not conclude that eating 10 cans of beans will achieve “100% of the advisable fat intake per day”. The DV is intended as a reference number only and not as a recommendation. The intake per day is advisable by the RDA/RDI, which will be discussed further in this article.
