It's important that your diet consists mostly of alkalinizing foods, since your body fucntions better and is more resistent to disease when it is overall in a more alkaline state, as opposed to acidic. It is now well known that a body that is predominantly acidic is far more prone to things such as arthritis, cancer, heart disease and many, many more ailments.
Almost all the ingredients of this salad are generally considered alkaline (with the exception of the mayo) and the yoghurt, which is more or less neutral:
3 cups finely sliced/chopped cabbage
2 cups finely grated carrot
1/3 cup raisins
3 tbs sunflower seeds
1 apple, diced (optional)
3 rings pineapple, diced (optional)
1 celery stick, chopped (optional)
5 heaped dessert spoons plain greek yoghurt
1 heaped dessert spoon tangy mayo
20 drops liquid stevia
Mix the first 7 ingredients together. For the "dressing", mix the yoghurt, mayo and stevia together well. Mix into the rest of the ingredients.
I usually add whatever ingredients I happen to have on hand, so if I don't have apple, pineapple and celery, I don't add them - it's great tasting either way.
If you would like the dressing more tangy, just use less yoghurt and more mayo. I like to use as little mayo as I can because of all the additives in there. I also like to sweeten it a little with some stevia - if you prefer it more tart, then leave this out. Also, if you're going to be using more mayo, then you may want to add more stevia for sweetness.
Incidentally, stevia is the most alkalinizing sweetener there is.
