Smoking and too much sunlight make your skin age more quickly, we read recently in a Danish study. Today we’ve dug up a French epidemiological study that was published in PLoS One in 2012. According to that study, you can delay the speed at which your skin ages by using olive oil daily.
The researchers also looked at the subjects’ diet, in particular the amount of mono-unsaturated fatty acids that the subjects consumed each day. On the basis of this they divided the participants into four equal-sized groups. These groups are called quartiles.
The results for the women were fairly similar, but not statistically significant.
Mono-unsaturated fatty acids are found in dairy products, meat and meat products, groundnut oil and sunflower oil – and in olive oil. However, it was only the mono-unsaturated fatty acids in olive oil that offered significant protection against facial aging. The more mono-unsaturated fatty acids from olive oil that the participants consumed, the fewer signs of skin aging the researchers found.
