Lectins | The Nutrition Source | Harvard T.H. Chan School ...
Lectins, or hemagglutinins, are an "anti-nutrient" that have received much attention due to popular media and fad diet books citing lectins as a major cause for obesity, chronic inflammation, and autoimmune diseases. They are found in all plants, but raw legumes (beans, lentils, peas, soybeans, peanuts) and whole grains like wheat contain the highest amounts of lectins.
Magnesite: A mineral used as a gem and in industry
Test with a refractometer: If your specimen has a polished surface and you have a refractometer (and are good at using it), you will be able to do one of the most reliable tests for magnesite. Magnesite has an index of refraction that ranges from about 1.509 to 1.700, and a birefringence of 0.191.
