Interesting links, thanks Junto.
I have been on a low lectin diet for some time now, avoiding the
nightshade family of foods (includes tomato, potato, bell peppers, aubergine/eggplant), the
bean family (includes all beans and peanuts), and
grains (includes wheat, corn, oats, rye and rice).
Grains I find are the hardest to avoid, because it then becomes a little difficult to get carbohydrates in your diet, especially since you can't have potatoes either (though sweet potatos or yams are fine).
Interestingly, if you eat some sugar (sucrose) at the same time, this affords some protection from the damaging effect of dietary lectins (
1). So if you are going to have some say some grains in your diet, along with their toxic lectins, then a "spoon full of sugar helps the toxins go down".
As far as
bovine colostrum is concerned, this supplement seems to prevent the increase in leaky gut (gut permeability) caused by NSAIDs (
1), but as for colostrum's ability to prevent the increase in gut leakiness due to heavy exercise (as stated in the link you provide), there seems to be conflicting evidence: the study your link refers to (here
1) says colostrum prevents the exercise-induced increase in gut leakiness, but another similar study said colostrum
increases exercise-induced gut leakiness (
1). So it seems it is not so clear.
In any case, when I took high doses of colostrum (2 heaped teaspoons daily), it I found it generally helpful for my ME/CFS.
