Loud, prolonged snoring interrupted with gasps and pauses in your breathing may signal a condition called sleep apnea. This cause and effect can be the result of an airway obstruction resulting in a drop in your oxygen level as you sleep. However, there are several reasons, other than sleep apnea, that can cause a reduction in blood oxygen levels. Each time you stop breathing, the amount of oxygen in your blood drops.
Eggs are obviously not dairy. In any case, the reason strict vegetarians would not eat eggs is not because they are animal products (that would be the reason vegans would not eat eggs) but rather because eggs might be fertilized and therefore are a potential life.
Milk, yogurt and cheese are all classified as dairy products on MyPlate, the United States Department of Agriculture's dietary guidelines. Products made from milk that retain their calcium content, whether the milk comes from cows, goats or other animals that produce milk, belong to the dairy family by the USDA classification. The USDA also classifies calcium-fortified soy milk as a dairy product, even though it's made from the soybean plant, not from animal milk. Foods made from milk that don't contain calcium are not classified as dairy products -- and thus don't belong to the milk, yogurt and cheese group. Dairy Products Milk is the most basic of dairy products.
