網上查了一下。（WGA 也是一種 Letin）
MAYO CLINIC 是這樣說的 （2018）：
“No scientific evidence exists to show that eliminating dietary lectins will cure any medical disorders or conditions, including autoimmune diseases.
Lectins are naturally occurring proteins that are found in most plants. Some foods that contain higher amounts of lectins include beans, peanuts, lentils, tomatoes, potatoes, eggplant, fruits, and wheat and other grains.
Some research seems to indicate that taking in large quantities of raw lectins could have negative health effects. The amount you’d need to consume each day to get to that level, however, is much higher than a typical diet would include. And studies have shown that lectins break down when processed or cooked, so the risk of adverse health effects arising from lectin-rich foods that aren’t raw is not cause for concern.”
一個2014年的綜述論文《Health effects of wheat lectins: a review》是這樣說的：
“Current data about health effects of dietary lectins, as consumed in cooked, baked, or extruded foods do not support negative health effects in humans. In contrast, consumption of WGA containing foods, such as cereals and whole grain products, has been shown to be associated with significantly reduced risks of type 2 diabetes, cardiovascular disease, some types of cancer, as well as a more favourable long-term weight management. Research is recommended to define actual active lectin contents in wheat-based foods after heat preparation for human consumption.”
