Why do you have to avoid fruit? Did Mother Nature make a mistake in producing fruit with all the nutrition in them? Chimpanzees do awfully well on fruit which consist of about 50% of their diet.
I do understand that people who have gotten their bodies in trouble be eating too much processed sweets and carbs (along with too much protein and fat) might have to curb their fruit intake temporarily to get their bodies back in balance. Is that what's going on with you?
I do think non-overly hybrid fruit should be the most sweet foods we should ever eat. Most things sweeter than fruit are processed by humans.
