View Full Version : Too much fruit?

Hi. I admittedly know nothing about nutrition, but always thought one ule was to eat as many fruits and veggies as you can, at least five a day of each. A lot that I've read around here and else where says to limit fruits. Why is that?

The issue with fruit is that it has a much higher carbohydrate content and GI than fibrous veggies, and it has a lower nutrient density. Eating too much of it can prevent ketosis, a metabolic state where your body burns fat (either dietary fat or bodyfat) for fuel in preference to glucose (carbohydrates), which is something many people here strive to remain in due to its numerous benefits.
It's pretty much the Paleo version of junk food. It's still healthy, but easier to overconsume than veggies are.

Fruits (today's UNnaturally selected, hybridized, super-sweet fruits) are high in sugar, particularly fructose.
There are two major ways that people can screw up the Paleo eating plan:
1 - Way too much fruit (and the accompanying sugar)
2 - Too many nuts (tree nuts are one of the top 8 allergenic food categories)
If one doesn't mess up with either of the above, they'll be golden.

Fructose is good and bad. Good in the fact that it has to be converted by the liver into glycogen first which is a longer process (and not raising insulin right away), bad in the fact that if too much fructose is consummed and liver glycogen stores are full, then it gets easily converted into fat. So...everything in moderation, but if you are focusing on weight loss especially, you want to create an environment of low insulin and low gylcogen so the body breaks into fat stores for conversion to glucose/energy. Some fruits are better ratio of fructose/glucose (high glucose=quicker rise in blood sugar=insulin spike).
