All seeds of the grass family - wheat, rye, rice, spelt, etc. - are high in lectins. You also find lectins in beans, dairy and in the nightshades (tomatoes, potatoes, eggplant).

This very often causes major digestive distress and the individuals often have no idea why as they assume their diet is clean.

You can throw some almonds in your steamer as you steam broccoli or brussel sprouts and you remove about 50% of the lectins and make the nuts more bioavailable (9).
