Mono fruits is convenient but not ideal. Our taste buds get tired of it quickly and we lose our appetite quickly. Eating just fruits is already difficult to get enough calorie. Now, mono fruits making even more difficult to eat.
Banana by itself is too sweet. Lemon by itself is too sour. By when you mixing both. You get the perfect combo taste. Because it taste better, we can enjoy more and eat more to get enough calorie.
Every fruit have it's strength and weakness. By pairing the right kind of fruits together, we get 10 times of excitement. And hopefully getting enough calorie.
There is no evidence that our body can only process one kind of food at a time.
Naturally, it's also possible to find banana and lemon at the same time. And when you are eating, just put them together.
