Because of this symmetrical geometry, CCl 4 is non-polar. Methane gas has the same structure, making carbon tetrachloride a halomethane. As a solvent, it is well suited to dissolving other non-polar compounds, fats, and oils. It can also dissolve iodine.
Yogurt is also a good source of calcium, potassium, and Vitamin D. Serving Size (1 cup), 1.49 micrograms of Vitamin B12 (25% DV), 137 calories. A Vitamin B12 deficiency may be marked by such symptoms as anemia, weakness, pale skin, weight loss, or upset stomach.
There is also evidence linking B12 deficiency to Alzheimerâs Disease, which is the most common cause of dementia in Western countries (4, 5). The only good food sources of B12 are animal foods like meat, fish and eggs. A deficiency is widespread among vegans and vegetarians, who avoid these foods. In one study, 92% of vegans and 47% of lacto-ovo vegetarians were deficient in this critical brain nutrient (6).
