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.
A vegan diet is one that eliminates all animal products and focuses only on plant-based foods. That not only means no meat, but also means no dairy and no eggs. Most vegans also try to avoid processed animal products, like gelatin, that sometimes get added to foods that seem like they would otherwise be vegan. Because the diet is low in calories, cholesterol and saturated fat, going vegan tends to help with weight loss and helps normalize your cholesterol and blood pressure. While more and more restaurants are offering vegan options, it can be hard to find a place to eat out in some parts of the country.
