Buffaloberries which grew mostly in the western U.S. and are regarded as a treat by bears are already being anointed as the "superfood" of 2014. Why? Because a study in Food Science, a very reputable journal, found that the berries contain carotenoids and phenols, compounds with antioxidant properties. Well, hallelujah!</p> Thu, 09 Jan 2014 03:30:41 +0000 Joe Schwarcz PhD 2063 at /oss /oss/article/food-you-asked/why-do-lobsters-change-colour-cooking <p>Believe it or not, shrimp and lobster have something in common with carrots. They have a good dose of carotenoids in their body. Carotenoids are yellow-orange compounds that are quite widespread in nature but the first one isolated was beta carotene from carrots which gave the name to the whole family. But they are also responsible for the colouring of orange juice, red peppers, watermelon, tomatoes, egg yolks, apricots, corn, pink grapefruit, pink salmon and pink flamingoes.</p> Tue, 06 Nov 2012 23:53:09 +0000 Joe Schwarcz PhD 1772 at /oss /oss/article/environment/why-do-leaves-have-autumn-colours <p>For many, the colour change of the leaves come September instigates a feeling of melancholy. Still, nobody denies that the reds, greens, oranges, and yellows are a spectacular sight! But what is behind this display that forebodes the long, bitter winter?</p> Wed, 07 Nov 2012 18:56:03 +0000 Amanda Scullion 1774 at /oss /oss/article/general-science-you-asked/why-milk-white-and-not-green-grass <p>Questions about milk are always interesting because, after all, it is our first food. Milk is meant to be the only sustaining food during early life and therefore it must contain all the required nutrients: water, proteins, fats, milk sugar, vitamins and minerals. Chlorophyll, the green colouring agent in plants, is not a required human nutrient and therefore evolution has not resulted in it being incorporated by the mother's body into milk. This is not to say that milk has no coloured substances in it, it does.</p> Wed, 31 Oct 2012 21:58:13 +0000 Joe Schwarcz 1730 at /oss
