Longer Life? NuVal may help you live a longer, disease free life.



So you enjoy NuValand find it extremely easy to use while grocery shopping, but ever wonder what trading up means for your health and wellness? A 2011 research article in the American Journal of Preventative Medicine discusses the relationship between NuVal and the risk of chronic disease.

NuVal, a nutritional scoring system, is part of an effort called nutrient profiling which ranks or classifies foods based on their nutrient compositions. The purpose of the one-number scores is to communicate the nutritional value of foods to shoppers and allow for comparisons between food products on the shelf. NuVal uses a scientific algorithm called the Overall Nutritional Quality Index (ONQI), which takes into account more than 30 nutrients and food properties. The NuVal score provides a summary of the nutritional information in a one-number score between 1 and 100.

Nutrients included in the algorithm have a known relationship with health outcomes, known public health importance, and are of benefit to public health if changes in the nutrients’ intake occur. Nutrients that generally have favorable effects on health are part of the top number, numerator, of the ONQI score. Nutrients that generally have unfavorable effects on health are part of the bottom number, denominator.

NuVal Score = Favorable Nutrients / Unfavorable Nutrients
The numerator is divided by the denominator to give the NuVal score. The higher the score, the better the nutrition. A few favorable nutrients include fiber, vitamin D, calcium, omega-3 fatty acids and iron. A few unfavorable nutrients include saturated fat, trans fat, sodium and added sugar. Other factors affecting the score include fat quality, protein quality, carbohydrate quality (glycemic load) and energy density.

NuValis the first nutrient scoring system to be evaluated for health outcomes. The goal of this study was to determine if the ONQI algorithm predicted lower risk of chronic disease over 20 years. Lifestyle habits, medical history, disease diagnosis, and dietary intake data were collected from 62,284 women and 42,382 men during the famous Nurses’ Health Study and Health Professionals Follow-up Study, respectively.

The study found that eating foods with higher NuVal scores was associated with lower risk of chronic disease and total mortality over 20 years. Specifically, eating higher scoring foods was strongly associated with lower risk of developing cardiovascular disease (CVD) and diabetes. What does this mean? People that ate foods with higher NuVal scores stayed healthier and lived longer!

NuVal has the ability to help shoppers choose foods to include in a healthy diet and lower the risk for disease. Let NuVal help you work to prevent disease every time you shop. Remember, the higher the score, the better the nutrition!
