Question: Is yogurt rich in protein?
About the article "Yogurt", section "Nutritional value and health benefits".

Candidate passages:
Strained yogurt contains significantly more protein than non-strained yogurt, including both casein and whey protein.
During the straining process, although the liquid whey is strained, the original whey and casein protein present in milk remain intact.
Strained yogurt, like non-strained yogurt, is also considered a good source of beneficial pro-biotics. 
Strained yogurt, yogurt cheese, labneh ( "labanah"), or Greek yogurt is yogurt which has been strained in a cloth or paper bag or filter to remove the whey, giving a consistency between that of yogurt and cheese, while preserving yogurt's distinctive sour taste.
Like many yogurts, strained yogurt is often made from milk which has been enriched by boiling off some of the water content, and sometimes by adding extra butterfat and powdered milk.
Yogurt strained through muslin is a traditional food in the Levant, Eastern Mediterranean, Near East, and South Asia, where it is often used in cooking, as it is high enough in fat not to curdle at higher temperatures.
Dishes may be cooked or raw, and may be savoury or sweet.
Due to the straining process to remove excess whey, even non-fat varieties are rich and creamy.
In western Europe and the US, strained yogurt has become increasingly popular because it is richer in texture than unstrained yogurt, and higher in protein.
Since the straining process removes some of the lactose, strained yogurt is lower in sugar and carbohydrates than unstrained yogurt.
Most of the recent growth in the $4.1 billion yogurt industry in the United States has come from the strained yogurt segment.
"Greek-style" yogurt is similar to Greek strained yogurt, but may be thickened with thickening agents, or if made the traditional way, is based on domestic (rather than Greek) milk. 
Yogurt is nutritionally rich in protein, calcium, riboflavin, vitamin B6 and vitamin B12.
It has nutritional benefits beyond those of milk.
Lactose-intolerant individuals can sometimes tolerate yogurt better than other dairy products, because the lactose in the milk is converted to glucose and galactose, and partially fermented to lactic acid, by the bacterial culture.
Yogurt containing live cultures has been found effective in a randomized trial at preventing antibiotic-associated diarrhea.
Yogurt contains varying amounts of fat.
There is non-fat (0% fat), low-fat (usually 2% fat) and plain or whole milk yogurt (4% fat).
A study published in the "International Journal of Obesity" (11 January 2005) also found that the consumption of low-fat yogurt can promote weight loss, relative to a gelatin placebo.
Yogurt is a valuable health food for both infants and elderly persons.
For children, it is a balanced source of protein, fats, carbohydrates, and minerals.
For senior citizens, who usually have more sensitive colons or whose intestines have run out of lactase, yogurt is also a valuable food.
Elderly intestines showed declining levels of bifidus bacteria, which allow the growth of toxin-producing and, perhaps, cancer-causing bacteria.
Yogurt may help prevent osteoporosis, reduce the risk of high blood pressure.
Yogurt with active cultures helps the gut, may discourage vaginal infections, and may help one feel fuller.
The "yogurt defense" was made famous by the trial of Carol Downer, one of the developers of menstrual extraction.
She was arrested at her self-help group and charged with practicing medicine without a license, as she inserted yogurt into the vagina of another woman to treat a yeast condition.
Carol Downer was acquitted; the jury did not equate inserting yogurt with practicing medicine.
TCBY has many flavors of frozen yogurt.
Some stores have soft serve and hard scooped yogurt, while some newer stores have only soft serve.
The soft serve only stores use a self-service model, with customers being charged by weight.
The soft serve yogurts consist of Golden Vanilla, Chocolate, and White Chocolate Mousse that are to be served daily, and then a variety of other flavors.
Most stores have at least three soft serve yogurt machines allowing them to serve at least one no sugar added soft serve yogurt flavor.
The No Sugar Added yogurt is made with splenda instead of regular sugar.
TCBY offers many regular and sugar free toppings.
One of the most popular toppings is wet walnuts, which consists of walnuts in hot artificial maple-flavored syrup.
TCBY also serves drinks such as Berriyo yogurt smoothies and Frappe Chillers.
In September 2010, TCBY said it was launching the test of breakfast and lunch meal replacement bowls, parfaits and smoothies made from non-frozen "fresh" yogurt called Yovana-Simply Yogurt in two self-service company stores in its headquarters of Salt Lake City.
TCBY announced in June 2011 that customers may visit stores in Little Rock and Harrison, Arkansas; Charlotte, North Carolina; and Memphis, Tennessee to taste Yovana, Simply Yogurt.
In May 2011, TCBY launched Super Fro-Yo, a reformulated version of its yogurt with a more nutrient-rich profile.
The company brought down the fat content of its yogurt to below 2 percent, so it can be labeled low fat.
However, the product has also maintained its rich, creamy texture with the addition of fiber, something American consumers are told to eat more of.
The fiber in TCBY's product also serves as a prebiotic, or food for the healthful bacteria in the yogurt, which boosts the benefit that live-and-active cultures bring to the digestive system.
Super Fro-Yo is also higher in protein, vitamin A, vitamin D, and calcium, and the product now includes seven types of probiotics.
To qualify as Super Fro-Yo, for example, the yogurt must have fewer than 120 calories per serving, a minimum of 10 percent of the daily recommendation for vitamin A and 20 percent of the recommended level of vitamin D, 1 gram or less of saturated fat, and a minimum of 20 billion live-and-active cultures at the point of manufacture.
On January 10, 2012, it was reported that TCBY would launch a Greek frozen yogurt product.
TCBY is the first frozen yogurt shop to offer Greek frozen yogurt.
Every year, TCBY offers mothers across the nation a free frozen yogurt on Mother's Day, and fathers a free frozen yogurt on Father's Day. 
Bulgarian yogurt is similar to other yogurt produced in the Balkans, but it has a distinctive flavor.
This is due to the milk of the Bulgarian sheep, which are raised on herb-rich pastures using traditional methods, and to the specific local strains of bacteria used.
Another factor influencing flavor is that Bulgarian yogurt is never sterilized after fermentation.
