No. The only thing I can see that might be a bit counterproductive is if you eat lots and lots and lots of fruits/veggies containing the same vitamins in a very short span of time--your body will not absorb ALL of the vitamin and will flush the excess out, but that's not a bad thing. So, eat 8 oranges in a half an hour and you won't get all the vitamin C, but you will get all that great fiber and other stuff fruits and veggies are good for.<br><br><br><br>
Also, I've heard that spinach can hinder iron absorbption or something like that, so I guess certain combinations of fruits and veggies could be seen as counterproductive.
Spinach does have iron but it also has oxi-some-thing-or-other that blocks iron absorption.<br><br><br><br>
The Diamonds who have written some veggie books follow theory of eating that many 7th day Adventists and others follow which claims that fruit can only be eaten on an empty stomach, or that you must wait a couple of hours after eating a vegetable, starch or protein before eating fruit. As I recall (unreliable at best) the reason is because the body on an empty stomach can absorb the nutrients in fruit. Apparently it can only be in the stomach 20 minutes at most before it begins to ferment (bad I guess). Any other food in the stomach slows the absorption and therefore causes fermentation and therefore malabsorbtion (sp?).<br><br><br><br>
They claim it is good science, other call it mumbo jumbo. You should read about it for yourself and see what you think.
taking vitamin C with something high in iron will increase absorption. taking iron with calcium, or tannins (tea) will decrease the iron absorption. The best sources of iron are cream of wheat and extra firm tofu, not liver as everyone would believe!
Hmm.. I'd always heard *not* to eat fruit on an empty stomach. Something about too much of a sugar rush (?). Not that I care. I just eat my fruits and veggies whenever I please. <img alt="" class="inlineimg" src="/images/smilies/smiley.gif" style="border:0px solid;" title=""><br><br><br><br>
