Typical costs: Having a contractor level and prepare the area then pour a concrete slab ranges from $1,000-$2,000 for a 10x20-feet; $4,000-$6,000 for 80x20-feet; and $5,000-$10,000 for 100x100-feet. Smaller projects cost more per square yard because of minimum travel, labor and equipment costs.
What makes yogurt - well, yogurt? The words live and active cultures refer to the living organisms, Lactobacillus bulgaricus and Streptococcus thermophilus, which convert pasteurized milk to yogurt during fermentation. Note that the milk is pasteurized before culturing to remove any harmful bacteria.
Frozen yogurt. Not all products termed 'frozen yogurt' actually contain live and active cultures. Some so-called 'frozen yogurts' use heat-treated yogurt, which kills the live and active cultures. Even with the live and active cultures, do not assume that a frozen yogurt is a healthy choice. Many frozen yogurts have just as much sugar per serving as the ice cream sitting next to it in the freezer section.
