What increases cholesterol in the blood is excessive consumption of certain saturated fats. As for the cholesterol provided by foods such as butter or egg yolk, normal consumption as part of a balance diet is not a problem. Cholesterol levels in the blood are linked to a number of factors: genetics, gender, age, lack of physical activity, obesity, etc. People who need to monitor their cholesterol levels should seek advice from their doctor or dietician/nutritionist.
Nutritional intake of butter
Butter is a fat made from the cream skimmed from milk. Twenty litres of milk are needed to make 1 kg of butter. Like all fats, it should be consumed in moderation. Although it is seen as a “treat”, butter is a non-negligible source of vitamins A and D.
What makes butter special is its irreplaceable flavour, great spread on bread or toast or used to enhance vegetables. A knob of butter makes green beans taste much better!
Micronutrients
Butter is a source of vitamin A and also provides vitamin D. These vitamins have the following properties:
-
-
- Vitamin A (or retinol) plays a role in:
- Vision
- Immunity (ability to fight illness)
- Growth
- Skin health
- Vitamin D (or calciferol) plays a role in:
- Bone health
- Muscle function
- Immunity (ability to fight illness)
Although butter comes from milk, it contains very little calcium (15 mg per 100 g compared with 120 g of calcium per 100 ml of milk).
- Vitamin A (or retinol) plays a role in:

Calorific value
The calorific value of butter is 75 Kcal per 10 g. It is a high-calorie food and should be consumed in moderation.
By comparison, oil, whether it is olive, sunflower, palm or any other kind of oil, contains 100% fat by definition. A soup spoon (10 g) provides 90 Kcal.
Light margarines contain as much fat and calories as butter. They are made from a mixture of different plant-based fats and other ingredients.
Fat
Of the 82% of lipids contained in butter, 54% are saturated fats, 22% monounsaturated fats and 2.8% polyunsaturated fats. It also contains 220 mg of cholesterol per 100 g.
Focus: Fatty acids in dairy products
Saturated fats are mainly found in milk fat. We now know that, depending on their nature, not all saturated fats have the same effect on health. The family of fatty acids is large and we are learning more and more about the roles each one plays. Depending on their biochemical structure, they can be divided into two families:
- Short-chain and medium-chain fatty acids
They are mainly found in milk fat and are quickly used by the liver, so are not stored in large quantities. They do not increase cholesterol levels and some even lower them. One of them protects against colorectal cancer.
- Long-chain fatty acids
Some of them, in particular palmitic acid, are likely to increase cardiovascular risk if they are consumed excessively. Others have a neutral effect on cholesterol levels and a positive effect on protein metabolism and omega-3 fatty acids.
Furthermore, dairy products also provide polyunsaturated fats in balanced proportions (omega-6 and omega-3) and monounsaturated fats with a positive health image.
