I'm transitioning back into my vegan diet after a few years of slobbing down meat. I came across this on blacksgoingvegan.com
What is a No White Foods Diet?
The No White Foods Diet is a low glycemic diet that eliminates foods low in nutrition and high in starchy carbohydrates and sugar. During the next 30 days while participating in the No White Foods Challenge, you will eliminate all refined white foods, most importantly white sugar and flour — both of which send blood sugar levels skyrocketing. For pre-diabetics, diabetics, and people who need to lose weight, controlling insulin and blood sugar are mandatory.
White foods are replaced with foods high in beta-carotene and polyphenols – which are vibrant colors of red, orange, yellow, green, and even purple. The few exceptions to the “no white foods” rule are egg whites cauliflower, parsnips, plant or animal milk, lean poultry and white fish, explained in more detail below.
Even though they may be vegan and actually good for you in moderation, white plant-based foods like potatoes and white beans are also no-no’s for the next 30 days. While on this program, you will also eliminate solid white fats from your diet such as butter and cheddar cheese (both of which are white before dyes are added to make them yellow).
The No White Foods Challenge is very simple to follow and provides a much healthier way of eating. You don’t need any special kitchen equipment or books to adhere to it, either. This is not a no-carb Atkins-style program! You will see eat carbohydrates daily, but they’ll be complex carbs full of fiber and vitamins… much healthier choices than you’ve been eating in the past.
Similar to how it just happens to be "master and slave drives"
