It's funny because the last time I posted, I said Vitamin C is great. I take that back. If you have very dry and sensitive skin, Vitamin C will burn your skin.
I've actually changed my diet a bit. I rarely eat fast food now (with the exception of pizza, it's my favourite). I make sure I eat a good amount of fruit and veggies. I make lots of smoothies and it does really help because I truly believe that you are what you eat. I also don't drink any soda, which was really hard for me. Not that I drank soda like crazy, beforehand. I just REALLY loved Pepsi/Coke. But now I mostly drink water, smoothies, tea and coffee. I do drink milk and it's very soothing to my body. I allow myself 1 cup of coffee, usually in the morning. When I drink tea, I add 2-3 spoons of organic honey. Honey is extremely beneficial for everyone and it's a great alternative to sugar. I eat lots of avocado, usually 1 or half of one, a day. Avocado is so beneficial for your skin, hair and nails, I think that everyone should be eating avocados. They contain so many nutrients that are perfect for helping skin. I eat eggs I would say 3-4 times a week. I know eggs have cholesterol but they are healthy and I've never had a link between eggs and eczema. I also eat a lot of sushi. Like avocado, this is so important for me. Fish is in sushi and fish has so many fatty oils and omegas. And I'm not a fan of fish so that is how I get my fish intake. I'm actually obsessed with sushi now.
I just want to note that most of the foods that I eat, are organic. I also try to stay away from foods that contain gluten. It's really hard but I'm just taking baby steps. Currently, I'm trying to cut my intake on sugar. I add 3 spoons of sugar in my coffee which is awful but sugar is the biggest drug known to man, so I don't expect it to be easy for me.
As far as skin care goes, I keep it very simple. I try to use products that don't contain too many complicated ingredients. And I also try to switch up my two moisturizers just to keep my skin on it's toes. Again, all my skin care is made for sensitive skin and I always read the ingredients.
Eczema, I feel, has to do a lot with what you put in your body. As well as allergies. People that suffer from eczema are just a lot more sensitive then most people. I don't mind making a change for my skin because it is helping me to lead a healthier life.
