Just watched a science programme and .. sugar is ageing and will make your skin look older
It's true-it helps to harden and wrinkle the skin through a process called glycation. It apparently becomes a real problem after about the age of 35 or so. I happen to have an addiction to sugar. While my diet is generally very healthy, sugar is my weakness.
I've tried to substitute xylitol for sugar but find that in the case of gum and candies, it seems to make me crave sugar all the more. I've grown accustomed to drinking my hot green or white tea with no sugar at all, and long ago eliminated soft drinks and juices. Sweet drinks have always been a weakness. But even so, I'll gorge on fruit and can't be like around things ice cream. My s.o. went into town and I asked him to bring me back a milkshake from a fast-food establishment-I know I should text him and tell him nevermind, but I really want that milkshare!
As far as my eating influencing my skin appearance-I can't say that when I'm substaining on fish, vegetables, fruits and nuts that it makes any discernable difference. I will
say that when I eat a great deal of sugary foods, I notice a lot more sprouting of random, unwanted hairs
But as far as skin appearance goes: it's the topical things-mainly moisturizing and using an alpha hydroxy treatment (in other words, exfoliating) that make the biggest improvement.
