Instead of buying sugar-laden, commercially manufactured yogurt....try this:
1 cup plain low-fat yogurt
1/4 cup pineapple chunks
1/2 banana, sliced
1 teaspoon flax seeds
unsweetened pineapple juice, to taste
Place all ingredients into bowl. Mix thoroughly. Adjust juice to your liking.
Besides getting more nutrients than store-bought versions, you have control over the ingredients.
