If you’re looking for information on Parmigiano Reggiano and cholesterol, someone has probably told you to be careful. Yet science tells a different—and much more delicious—story than you might expect. 100 gr. of Parmigiano Reggiano DOP contain about 83–88 mg of cholesterol, a figure that pales in comparison to the 1,232 mg per 100 gr. found in egg yolk. The comparison speaks for itself.
The short answer to the most frequently asked question is this: Parmigiano Reggiano is not only safe for those watching their cholesterol, but it is one of the “lightest” aged cheeses in this regard. Of course, as with any nutritious food, portion size and frequency make all the difference.
How much cholesterol does Parmigiano Reggiano contain?
The most direct question deserves an equally direct answer. According to the nutritional database of CREA (Center for Food and Nutrition Research), 100 gr. of Parmigiano Reggiano DOP contain approximately 83–88 mg of cholesterol. For a standard 30-gr. serving—the amount recommended by nutrition experts—this amounts to just 25–26 mg of cholesterol, compared to 10 gr. of high-biological-value protein and 360 mg of bioavailable calcium.
To put this into immediate context: the World Health Organization recommends not exceeding 300 mg of dietary cholesterol per day. A 30-gr. serving of Parmigiano therefore accounts for less than 10% of this threshold. This fact puts many concerns into perspective.

Grana Padano Institute - Nutrition Education
The most striking fact is the comparison with Grana Padano: the latter, often perceived as a “lighter alternative,” actually contains about 20–25 mg more cholesterol per 100 gr. Parmigiano Reggiano DOP is therefore the aged hard cheese with the most favorable lipid profile.
Parmigiano Reggiano or Grana Padano: Which Is Less Harmful to Cholesterol?
This is one of the most frequently asked questions, and it finally has a clear answer. With about 88 mg of cholesterol per 100 gr., Parmigiano Reggiano DOP is better than Grana Padano (about 109 mg/100 gr.) in terms of both cholesterol and protein content: Parmigiano Reggiano, in fact, offers about 33 gr. of protein per 100 gr. compared to about 32 gr. in Grana Padano, with a higher nutritional density despite a lower cholesterol content.
The difference is partly explained by the production regulations: Parmigiano Reggiano is made with partially skimmed milk (through the natural separation of cream), while Grana Padano follows a slightly different process. Both are protected DOP products, but for those monitoring their lipid profile, Parmigiano Reggiano is the better choice.
Parmigiano Reggiano and Cholesterol: Does Aging Matter?
One of the most technical—and most interesting—questions concerns whether and how aging affects the cholesterol content in Parmigiano Reggiano. A study by the University of Bologna (AMS Thesis, CRPA Lab) analyzed samples of 24- and 36-month-old Parmigiano Reggiano DOP from three different dairies, evaluating variations in the lipid fraction.
The study showed that as aging progresses, free water decreases and nutrients become more concentrated—including cholesterol. In absolute terms, a 36-month Parmigiano will tend to have slightly higher values than a 24-month one, but the difference is small and offset by significantly greater digestibility. The process of proteolysis (protein breakdown) that occurs during the long aging process makes the product more easily digestible and less taxing on the metabolism.

Does Parmigiano Reggiano raise cholesterol? The Fundamental Distinction.
One of the most common confusions in nutrition is that between dietary cholesterol (the kind found in food) and blood cholesterol (the kind in the blood, measured in tests). Several studies—including a 2020 review in the Journal of the American College of Cardiology —suggest that dietary cholesterol has a more limited impact on blood levels than previously believed, especially compared to saturated and trans fats.
Saturated fats are the main factor stimulating the endogenous production of LDL cholesterol in the liver. Parmigiano Reggiano contains about 18 gr. of saturated fat per 100 gr.—a significant amount, but in a 30-g serving, this corresponds to about 5.4 gr., well within the limits of a balanced Mediterranean diet. The Parmigiano Reggiano Consortium recommends 2–3 servings per week, each weighing 30–40 gr.
Parmigiano Reggiano does not significantly raise blood cholesterol when consumed in the recommended portions (30 gr.).
Its high calcium content (1,155 mg/100 gr.) may promote the intestinal excretion of saturated fats, thereby reducing their absorption.
Bioactive peptides released during aging (such as those derived from casein) have shown antihypertensive properties in some preliminary studies.
Its low lactose content (virtually absent after 24 months of aging) makes it suitable even for those with lactose intolerance.
Its very high protein density ( 33 gr. of protein per 100 gr.) makes it filling: you eat less, which indirectly promotes lipid control.
How much Parmigiano can you eat if you have high cholesterol?
The answer isn’t a ban, but moderation. In a diet for hypercholesterolemia, Parmigiano Reggiano can be included by following these guidelines:
Maximum serving size: 30–40 gr. per serving (equivalent to 2–3 generous shavings).
Frequency: 2 times a week, avoiding pairing it with other foods high in saturated fat in the same meal.
As grated: 5–10 gr. per dish (equivalent to about 1–2 level tablespoons) does not significantly affect the daily lipid profile.
Preferred aging: 24 or 30 months offers the best balance between digestibility, cholesterol content, and flavor intensity.
Recommended pairings: fruit, raw vegetables, legumes—fiber-rich foods that help reduce cholesterol absorption.
If you are taking statins or other lipid-lowering medications, there are no known interactions with Parmigiano Reggiano. However, for a personalized diet, it is always advisable to consult your doctor or nutritionist.
Saturated Fats vs. Cholesterol in Parmigiano: The distinction that changes everything.
Many people with high cholesterol worry about dietary cholesterol but overlook saturated fats—which, paradoxically, have a more direct impact on LDL levels in the blood. Parmigiano Reggiano has a complex fat profile: in addition to saturated fats, it contains a significant amount of monounsaturated fatty acids (such as oleic acid) and a small percentage of polyunsaturated fats, including conjugated linoleic acid (CLA), a fatty acid found in the milk of grass-fed cattle and associated in the literature with potential beneficial effects on lipid metabolism.
The complete lipid profile of Parmigiano Reggiano is therefore not that of a simple “fatty cheese”: it is a complex matrix, in which the presence of calcium, proteins, and micronutrients modulates the overall metabolic impact in a more favorable way than simply reading the “saturated fat” value on the label.
💡 Did you know that…
100 gr. of Parmigiano Reggiano DOP contain about 83–88 mg of cholesterol, while 100 gr. of egg yolk contain over 1,200 mg— almost 15 times more . Yet eggs are often considered more “diet-friendly.” Parmigiano also offers complete proteins of the highest biological value, bioavailable calcium, and such high digestibility that 100 gr. are absorbed in just 45 minutes, compared to the 3–4 hours required for the same amount of meat.
Parmigiano Reggiano in the Mediterranean Diet: A Rightful Place.
The Mediterranean Diet, recognized by UNESCO as Intangible Cultural Heritage of Humanity, does not exclude aged cheeses: it includes them as a concentrated source of protein and calcium, to be consumed in moderation. Parmigiano Reggiano DOP fits perfectly into this framework, thanks to its nutritional density, versatility in the kitchen, and low lactose content, which makes it accessible to most adults.
For the elderly—a group often disadvantaged by dietary restrictions related to cholesterol—Parmigiano Reggiano is particularly valuable: its high calcium content (1,155 mg/100 gr., nearly double the daily requirement in a 50-gr. serving) and protein content make it an ally against osteoporosis and sarcopenia, conditions far more common and debilitating than a slight increase in dietary cholesterol.
Have you discovered that Parmigiano Reggiano is compatible with a cholesterol-conscious diet?
Now all you have to do is choose the aging profile that’s right for you: from the classic 24-month to the prized 22-year-old, have it delivered directly to your home in just a few days, and enjoy it with friends and family with peace of mind.
