Dairy & Egg Nutrition Calculators
Dairy products and eggs are among the most nutrient-dense animal foods — packed with complete protein, calcium, vitamin D, and B12 — yet the nutritional gap between a boiled egg and a cheese omelette can exceed 300 kcal. This collection provides 2 free nutrition calculators covering multiple cheese varieties and egg preparations.

From Cottage Cheese to Cheddar: Why a 100g Serving Can Mean 72 or 403 Calories
Cheese is arguably the most nutritionally variable single food category. Low-fat cottage cheese provides 72 kcal per 100g with 12.4g of protein and 1g of fat. Cheddar cheese delivers 403 kcal with 22.9g of protein and 33.3g of fat. Cream cheese sits at 342 kcal with only 5.9g of protein. These are not minor differences — they represent fundamentally different foods from a macronutrient perspective, unified only by their dairy origin.
Our cheese calculator includes 8–12 varieties from mozzarella to parmesan to paneer, each with accurate USDA-verified data. This specificity matters because many people track “cheese” generically, using an average that may be 100–200 kcal off from the variety they actually consumed.
The Egg: Nature's Most Complete Nutrient Package in 50 Grams
A single large egg contains meaningful amounts of 13 essential vitamins and minerals — including 169mg of choline (31% DV), 1.2μg of vitamin D (6% DV), 0.5μg of vitamin B12 (21% DV), and 15.6μg of selenium (28% DV). It delivers 6.3g of protein with a PDCAAS score of 1.0, the highest possible protein quality rating. All of this comes in a 72-calorie package that costs less than most supplements.
The yolk vs. white debate is largely settled: the yolk contains all the fat, cholesterol, and fat-soluble vitamins (A, D, E, K), while the white provides approximately half the total protein with almost zero fat. Discarding the yolk eliminates the cholesterol but also removes the choline, vitamin D, and most of the iron. Our calculator lets you compare whole egg, yolk only, and white only so you can see the exact nutritional trade-off.
Dairy & Egg Nutrition Questions
- How many calories are in one large egg?
- One large egg (50g) contains approximately 72 kcal, with 6.3g protein, 0.4g carbohydrates, and 4.8g fat. The yolk contains all the fat (4.5g), most of the calories (55 kcal), and the majority of micronutrients including vitamin D, choline, and B12. The white provides 17 kcal and 3.6g of protein with almost no fat.
- Is eating whole eggs bad for cholesterol?
- Current evidence does not support the old recommendation to limit whole eggs. A 2020 meta-analysis in the BMJ (1.72 million participants) found no significant association between moderate egg consumption (up to 1 egg per day) and adverse outcomes in healthy adults. The 2015–2020 Dietary Guidelines for Americans removed the previous 300mg daily cholesterol cap. One egg contains approximately 186mg of cholesterol, but dietary cholesterol has a modest effect on blood cholesterol for most people — saturated and trans fats have a much larger impact.
- Which type of cheese has the highest protein per calorie?
- Cottage cheese (low-fat) is the clear winner for protein per calorie among common cheeses: approximately 11g protein per 100 kcal. Part-skim mozzarella provides about 10g protein per 100 kcal. In contrast, cheddar provides only 7g per 100 kcal, and cream cheese just 2.5g per 100 kcal. For high-protein diets, cottage cheese and part-skim mozzarella are substantially more efficient protein sources than aged cheeses.
- How does the protein quality of eggs compare to other protein sources?
- Egg protein has the highest Protein Digestibility Corrected Amino Acid Score (PDCAAS) of 1.0 — the maximum possible score. It was historically used as the reference standard against which all other protein sources were compared. Egg protein is a complete protein with all nine essential amino acids in optimal ratios. Per gram of protein, eggs are also one of the most affordable animal protein sources.
- Does cooking method affect the nutritional value of eggs?
- The protein and mineral content remains essentially the same across cooking methods. The main variable is added fat: a boiled egg adds 0 kcal from cooking fat, while a fried egg (in 1 teaspoon of butter) adds approximately 34 kcal. Scrambled eggs with milk and butter can add 30–50 kcal per egg. Our calculator includes boiled, poached, fried, scrambled, and omelet variants to capture these differences accurately.
