A âdwarf planetâ is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.ith the exception of Ceres, which is located in the asteroid belt, the other dwarf planets are found in the outer solar system. There are another 6 objects in our solar system that are almost certainly dwarf planets and there may as many as 10,000.
With the exception of vitamin B 12 a vegan diet can in principle provide all necessary nutrients. However, in practice, vegans are frequently deficient in calcium , iron , vitamin D , selenium , phosphorous , and zinc . Vitamin B 12 presents a special issue. This vitamin is not provided to any meaningful extent by non-plant foods. (The algae spirulina contains B 12 , but in a non-absorbable form.) Deficiency in B 12 is therefore inevitable among those who follow a strict vegan diet and do not take supplements.
Calories, Protein & Fat. It is important for people trying a vegan diet to include some high-calorie, high-protein foods in order to feel satisfied. Simply removing animal products from a typical American diet is going to leave you with mostly low-calorie foods such as salads, vegetables, and fruit.
