What is MyNetDiary’s Food Grade, and how can it help you most?

  • 5 Minute Read

The Food Grade is a handy MyNetDiary tool that helps you compare healthiness among similar foods using simple letter grades–from A to D. Instead of pouring over Nutrition Facts panels of multiple products, you can use Food Grade to spot the best choices for healthy eating at a glance!

Here’s what you need to know about how Food Grade works and certain limitations of this nifty scoring system.

What is the food grade

Key Takeaways

  • MyNetDiary assigns foods a letter grade from A through D, making it easier for you to compare similar food products quickly without getting lost in multiple Nutrition Facts panels.
  • Food Grade is based on 12 nutrients: fiber, protein, vitamin A, vitamin C, calcium, and iron boost the scores, while total fat, saturated fat, cholesterol, sodium, total carbohydrates, and sugar drag it down. This helps you spot healthier choices much faster!
  • Food Grade works best when choosing between similar foods, like different types of cheese or pasta, rather than judging a food’s overall worth in your diet or healthy-eating pattern.
  • Food Grade has some limitations to keep in mind. For example, it doesn't consider calories, or healthy fats like omega-3s, potassium, or vitamin D, so nutritious foods like olive oil can come up low.

What is the Food Grade, and how is it calculated?

Food Grade is just what it sounds like. It is a letter grade (A, B, C, or D) that MyNetDiary uses to rank the healthiness of a food product based on a "food score" derived from a math formula.

These food scores will vary from -5 (less healthy) to +5 (more healthy) for serving sizes shown on the Nutrition Facts panel of a food product. For more detailed information about the food score and how it's calculated, see the appendix at the end.

Our Food Grade is calculated using these 12 nutrients, most of which appear on the Nutrition Facts panel:

Some nutrients have a bigger impact on Food Grade than others

Positive contributors

Negative contributors *

*Foods with a higher amount of these nutrients will hurt the food score. For instance:

Item Serving Size Food Score
SpaghettiOs spaghetti in tomato and cheese sauce 1 cup -1
Spaghetti cooked, enriched, without salt 1 cup 2
Spaghetti, whole wheat, cooked 1 cup 4

Some folks are numbers people, and others prefer grades. MyNetDiary developed a simple conversion between the food score and the food grade.

Higher positive scores mean healthier options, so they get a higher grade. The negative scores means foods are less healthy, so they get a lower grade.

Food Grade Food Score
A ≥ 1.5
A- 1
B+ 0.5
B 0
B- -0.5
C+ -1
C -1.5
C- -2
D+ -2.5
D ≤ -3

Serving size matters

If you log a larger or smaller serving size, your score will inherently shift the food's score, depending on the nutrient content.

How should I use Food Grade?

Use Food Grade to compare similar foods, not to judge a food’s value.

To reach these healthy dietary goals, choose foods and drinks with higher food grades.

When you stick to that, you'll likely choose more foods that are:

Following a low-carb or keto diet?

If you follow a low-carb or keto diet, MyNetDiary's got you covered! The Food Grade system for these diets uses a separate scoring system to help you refine your choices and find healthier foods that fit these diet plans.

Once you select Keto or Low-Carb Premium diets, the respective Food Grade system will automatically be enabled.

What are the limitations of Food Grade?

Healthy eating is nuanced, and a healthy diet is about more than the Food Grade system. Listen to your body, and team up with your medical provider and dietitian to craft an eating plan that fits your unique health goals and eating preferences.

Frequently Asked Questions

What is the MyNetDiary Food Grade?

Food Grade is a tool that gives a letter grade from A to D for each food product in MyNetDiary's database, ranking how healthy a food product is. It converts a numerical food score (usually between -5 to +5) into an easy-to-read grade. The higher the grade, the healthier choice!

How is the Food Grade calculated?

Food Grade is calculated from 12 nutrients using a food scoring method published in 2009 in the Journal of the American Dietetic Association. Nutrients like fiber, protein, and calcium boost the score, while saturated fat, sodium, and sugar drag it down. The serving size also affects the food grade.

Does Food Grade include calories?

No. Food Grade doesn't account for calories. If weight loss is your goal, track your calories separately, and use Food Grade to find the more nutritious option when comparing similar foods.

Does Food Grade work for keto or low-carb diets?

Yes! MyNetDiary has specific keto and low-carb Food Grades, each with its own scoring system. When you select Keto or Low-Carb Premium diets, the matching Food Grade system turns on automatically to help you find healthier foods that fit your eating plan.
