For olive oils whose chemical composition is verified, three nutritional and health claims among those recognised by EFSA (European Food Safety Authority) can be made and are legally allowed.
RICH IN MONOUNSATURATED FATS
Substituting saturated with unsaturated fats in the diet contributes to maintaining normal blood cholesterol levels.
The daily fat intake for an adult is 70 g, and choosing a fat rich in monounsaturated (such as olive oil) or polyunsaturated fatty acids (such as the majority of vegetable oils) over fats rich in saturated fatty acids (animal fats) contributes to maintaining normal blood cholesterol levels.
Furthermore, olive oil’s higher content of monounsaturated fatty acids compared to polyunsaturated ones makes it more stable during cooking.
HIGH VITAMIN E CONTENT
Vitamin E contributes to protecting cells from oxidative stress
If a foodstuff contains a minimum amount of 1.8 mg of vitamin E per 100 g, it can be considered a “source of vitamin E”, whereas if it contains at least twice that amount (3.6 mg) it should be considered a food “high in vitamin E”.
Of course, a good extra virgin olive oil can contain more than 20 mg% of vitamin E, or more than 166% of our daily requirements of vitamin E
OLIVE OIL POLYPHENOLS
Olive oil polyphenols contribute to protecting blood lipids from oxidative stress
The bitter, spicy flavour of good extra-virgin olive oils comes from the presence of special antioxidants called “olive oil polyphenols”.
These substances contribute to protecting blood lipids from oxidative stress; a daily intake of 20 grams of extra-virgin olive oil, which contains 25 mg% of polyphenols, has a beneficial effect.
