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.
Almost all eggs are Kosher. Under Kosher dietary laws, neutral eggs are considered neither milk nor meat and may be eaten with either. Kosher-certified eggs are produced according to biblical laws governing the selection and preparation of foods.
