Chiasma (genetics) In genetics, a chiasma (pl. chiasmata) is the point of contact, the physical link, between two (non-sister) chromatids belonging to homologous chromosomes. At a given chiasma, an exchange of genetic material can occur between both chromatids, what is called a chromosomal crossover, but this is much more frequent during meiosis than mitosis. In meiosis, absence of a chiasma usually result in improper chromosomal segregation and aneuploidy.
For example, certain kinds of breast cancers are insulin sensitive, and thus eating a lot of carbohydrates (ironically like in a vegan diet) would cause your body to produce lots of insulin, making this an inefficacious strategy in reducing risk for those particular kinds of cancer.
Vegan Nutrition. The key to a nutritionally sound vegan diet is variety. A healthy and varied vegan diet includes fruits, vegetables, plenty of leafy greens, whole grain products, nuts, seeds, and legumes. Work on limiting, or avoiding processed foods, which are hard to digest and are without the energy of live whole foods (whole foods are those that you eat the way they grow).
