These beauty smoothies really work
If you drink a smoothie containing lots of carrot juice, orange juice and other sources of carotenoids, within a couple of weeks your skin will become a colour that most people find attractive. Psychologists at the University of Nottingham Malaysia Campus announced this in PLoS One.
Carotenoids such as lycopene [structural formula shown above] and alpha- and beta-carotene [structural formulae shown below] protect the skin. After being absorbed from food they accumulate in the skin where they inhibit aging processes. As a result, the colour of the skin changes too. In 2011 Scottish psychologists showed that people with relatively high amounts of carotenoids in their skin are more attractive than people with low levels of carotenoids in their skin.
The researchers varied the composition of the smoothies. The composition is shown below. Click on the figure for a larger version. The researchers also added a small amount of fat – in the form of cream of palm oil – to boost the absorption of the carotenoids.
The smoothies provided an average of 25 mg carotenoids per day, as the table above shows. Click on the figure for a larger version. The carotenoids consisted of 80 percent beta-carotene, 15 percent alpha-carotene and 5 percent lycopene.
