6-Alfalfa Sprouts
These tasty little greens are often added to salads, soups, and even burgers. For many nutritionists, alfalfa sprouts also make their lists of “superfoods.” However, eating them raw has raised a few health concerns. For one thing, alfalfa sprouts are likely to become contaminated with E. coli. If the grower and the consumer take proper precautions, though, this shouldn’t be too much of an issue. Many store-bought veggies are just as likely to pose a similar risk. However, the most significant concern with alfalfa sprouts is that they contain a toxin called L-canavanine. This nonprotein amino acid naturally occurs in many plant species to provide a defense against insects. But it also causes severe responses in autoimmune-compromised persons.
Studies on animals with autoimmune tendencies have shown that consuming vegetables containing L-canavanine caused an increase in conditional flare-ups. Some people have even found it to be a contributing factor to the development of specific diseases like lupus. Specialists are still conducting studies in humans to nail down the exact connections between raw sprouts and autoimmune problems. For now, though, they recommend that anyone with a compromised immune system steer clear of these little sprouts.
