The question of whether white or yellow cheese is healthier is misguided because a cheese’s color is a superficial characteristic that offers no reliable insight into its nutritional makeup. The true health profile of any cheese depends entirely on its specific ingredients, the type of milk used, and the manufacturing process it undergoes. To make an informed choice, consumers must look beyond the color and focus on measurable metrics like fat content, calorie density, and sodium levels. The answer lies in the details of the nutrition label and the style of cheese production, not the shade of the cheese.
Why Cheese Color Does Not Indicate Nutritional Value
The color of cheese is primarily determined by two factors: the cow’s diet and the addition of a natural colorant. Cheese made from cow’s milk naturally takes on a yellowish hue when the animals consume fresh grass, which is rich in the fat-soluble pigment beta-carotene. This pigment is passed into the milk fat, giving the cheese a subtle yellow color.
However, many yellow or orange cheeses, such as most commercial cheddar, achieve their color through the addition of annatto. Annatto is a natural, plant-based colorant derived from the seeds of the tropical Bixa orellana tree. This ingredient has no impact on the flavor or nutritional composition of the final product. Therefore, a white cheddar and a yellow cheddar made from the same recipe only differ by the presence of this non-nutritive coloring.
Calorie Density and Fat Content
The most significant factor determining a cheese’s calorie density is its fat content, specifically saturated fat. Cheese varieties are broadly categorized by their moisture content, which is inversely related to their fat concentration and energy density. Harder, aged cheeses generally have less moisture and a higher concentration of fat and calories per ounce than softer, fresh cheeses.
For example, a hard cheese like Parmesan is high in fat and calories, while a soft, white fresh mozzarella or ricotta has a higher moisture content, resulting in a lower calorie count per serving. When selecting cheese for reduced fat intake, the best option is often a part-skim or reduced-fat version, regardless of its color. These modifications lower the saturated fat and calorie counts compared to their full-fat counterparts.
Lower-fat cheeses like cottage cheese are predominantly white and contain significantly fewer calories than most aged, yellow cheeses. However, some white cheeses, such as Manouri, a creamy Greek cheese, can still be very high in fat.
Sodium Levels and Processing Differences
Sodium content varies widely among cheeses. Salt is a necessary ingredient in cheesemaking, as it influences flavor, texture, and acts as a preservative. Generally, the longer a cheese is aged, the higher its sodium concentration becomes because the salt is concentrated as moisture evaporates.
Aged, hard cheeses like Parmesan and mature Cheddar, regardless of their yellow or white color, tend to be high in sodium, sometimes exceeding 500 milligrams per ounce. Conversely, fresh, white cheeses like ricotta, fresh mozzarella, and Swiss cheese are typically among the lowest sodium options. Fresh mozzarella, which is often packed in water or brine, can contain as little as 40 milligrams of sodium per ounce.
Processing also affects the final sodium level; for instance, processed American cheese, which can be yellow or white, is often very high in sodium due to added salts and emulsifiers.
How to Select Cheese Based on Health Goals
Consumers should disregard the cheese’s color and instead prioritize reading the Nutrition Facts panel to align their choice with specific health goals. If the goal is to limit saturated fat and calories, the primary focus should be on the grams of total and saturated fat per serving. Selecting cheeses labeled as “part-skim” or “reduced-fat” will reliably lower these metrics compared to full-fat options.
For individuals monitoring their blood pressure or overall sodium intake, the milligram count of sodium is the most relevant number. Low-sodium goals are best met by choosing fresh, white varieties like Swiss, fresh mozzarella, or low-sodium cottage cheese. Conversely, those seeking a concentrated source of protein and calcium may select harder cheeses, but should be mindful of the higher calorie and sodium load that accompanies them.
