I can easily eat 6 large naval oranges and have many times. What, you will tell me oranges have been hybridized to be sweeter? I'm sorry man, you are soooo wrong. The sweetness is all about the weather and everyone knows that. The naval oranges now are the same stock they were one hundred years ago. How do I know this? Because, we have the original imported tree in my home town and it's the same as all the other stock. It's the SAME, the very first one that was imported. Nothing, absolutely nothing has changed. This tree was imported to Brazil where it wasn't sweet at all and basically wasn't marketable. They had no idea what had gone wrong from the same stock that came from Spain. Then someone brought a sample to my home town and voila, it was once more producing very sweet oranges. Why? Because we have cold winter nights and that stimulates the oranges to become sweeter to resist freezing. When it gets below freezing the oranges will still not freeze because of the natural sugars. However, if you bump them, they will get frost damage on the disturbed portion and fill up those cells with fibers. I'm sorry man to insult you but basically, you're talking out your ass about stuff you know nothing about.
