Yogurt /Curd is a fermented dairy product made by adding bacterial cultures to milk, which causes the transformation of the milk's sugar, lactose, into lactic acid. This process gives yogurt its tart flavor and unique pudding-like texture a quality that is reflected in its original Turkish name, Yoghurmak, which means "to thicken." Apart from its popular taste, texture and characteristic tanginess, yogurt has been found to have numerous health benefits.
One of the first records of yogurt consumption comes from the Middle East during the times of the Conqueror Genghis Khan in the 13th century, whose armies were sustained by this healthful food. Yogurt and other fermented dairy products have long been a staple in the diets of cultures of the Middle East, Asia, Russia and Eastern European countries, such as Bulgaria.
Yogurt is mentioned in some of the Ahadith too.
Hazrath Abdur-Rahman Rz. was reported to have bought yogurt and butter in the marketplace.-( Bukhari )
Hazrath Said bin Jubair Rz. narrated: Hazrath Ibn Abbas Rz. said: Bibi Um Hufaid Rz., Ibn 'Abbas's aunt sent some dried yogurt (butter free), ghee (butter) and a mastigar to the Prophet (May Allah bless him and give him peace) as a gift. The Prophet (May Allah bless him and give him peace) ate the dried yogurt and butter but left the mastigar because he disliked it. Ibn 'Abbas said, "The mastigar was eaten at the table of Allah's Apostle (May Allah bless him and give him peace) and if it had been illegal to eat, it could not have been eaten at the table of Allah's Apostle(May Allah bless him and give him peace)."
Hazrath Anas Rz. narrated: The Prophet (May Allah bless him and give him peace) stayed for three days at a place between Khaibar and Medina, and there he consummated his marriage with Bibi Safiyya bint Huyay Rz.. I invited the Muslims to a banquet which included neither meat nor bread. The Prophet (May Allah bless him and give him peace) ordered for the leather dining sheets to be spread, and then dates, dried yogurt and butter were provided over it, and that was the Walima (banquet) of the Prophet (May Allah bless him and give him peace).
Today, yogurt plays an important role in many different world cuisines including Turkey, Greece, India, and countries in the Middle East, Eastern Europe and Asia.
The lactic acid bacteria that are traditionally used to make yogurt Lactobacillus bulgaricus and Streptococcus thermophilus also give yogurt many of its health benefits.
Yogurt is a very good source of iodine, calcium, phosphorus, and vitamin B2. It is also a good source of protein, vitamin B12, potassium, molybdenum, zinc and pantothenic acid.
Yogurt smooths skin, soothes the stomach, and even polishes candlesticks.
Health benefits of yogurt:
Some of the health benefits of yogurt are as follows:
1.Promotes Good Digestion:
Yogurt is easier to digest than milk. Many people who cannot tolerate milk, either because of a protein allergy or lactose intolerance, can enjoy yogurt. The culturing process makes yogurt more digestible than milk. The live active cultures create lactase, the enzyme lactose-intolerant people lack, and another enzyme contained in some yogurts (beta-galactosidase) also helps improve lactose absorption in lactase-deficient persons. Bacterial enzymes created by the culturing process, partially digest the milk protein casein, making it easier to absorb and less allergenic.
2.Yogurt contributes to colon health.Yogurt contains lactobacteria, intestines-friendly bacterial cultures that foster a healthy colon, and even lower the risk of colon cancer. Lactobacteria, especially acidophilus, promotes the growth of healthy bacteria in the colon and reduces the conversion of bile into carcinogenic bile acids. The more of these intestines-friendly bacteria that are present in the colon, the lower the chance of colon diseases. Basically, the friendly bacteria in yogurt seems to deactivate harmful substances (such as nitrates and nitrites before they are converted to nitrosamines) before they can become carcinogenic.
Calcium is necessary for strong bones and healthy teeth yogurt is a rich source of calcium - a mineral that contributes to colon health and decreases the risk of colon cancer. Calcium discourages excess growth of the cells lining the colon, which can place a person at high risk for colon cancer. Calcium also binds cancer-producing bile acids and keeps them from irritating the colon wall. People that have diets high in calcium have lower rates of colorectal cancer.
3. Yogurt improves the bioavailability of other nutrients. Culturing of yogurt increases the absorption of calcium and B-vitamins. The lactic acid in the yogurt aids in the digestion of the milk calcium, making it easier to absorb.
2. Boosts Immune Function :
Yogurt can boost immunity. Researchers who studied 68 people who ate two cups of live-culture yogurt daily for three months found that these persons produced higher levels of immunity boosting interferon. The bacterial cultures in yogurt have also been shown to stimulate infection-fighting white cells in the bloodstream. Some studies have shown yogurt cultures to contain a factor that has anti-tumor effects in experimental animals.
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 in a texture that kids love. For elderly people, who usually have more sensitive colons or whose intestines have run out of lactase, yogurt is also a valuable food.
5. Yogurt aids healing after intestinal infections. Some viral and allergic gastrointestinal disorders injure the lining of the intestines, especially the cells that produce lactase. This results in temporary lactose malabsorption problems. This is why children often cannot tolerate milk for a month or two after an intestinal infection. Yogurt, however, because it contains less lactose and more lactase, is usually well-tolerated by healing intestines and is a popular "healing food" for diarrhea.
6. Yogurt can decrease yeast infections.
7. Yogurt is a rich source of calcium. An 8-ounce serving of most yogurts provides 450 mg. of calcium, one-half of a child's RDA and 30 to 40 percent of the adult RDA for calcium. Because the live-active cultures in yogurt increase the absorption of calcium, an 8-ounce serving of yogurt gets more calcium into the body than the same volume of milk can.
The calcium intake from yogurt helps the body to burn body fat rather than store it.
8. Yogurt is an excellent source of protein. Plain yogurt contains around ten to fourteen grams of protein per eight ounces, which amounts to twenty percent of the daily protein requirement for most persons. In fact, eight ounces of yogurt that contains live and active cultures, contains 20 percent more protein than the same volume of milk (10 grams versus 8 grams). Besides being a rich source of proteins, the culturing of the milk proteins during fermentation makes these proteins easier to digest. For this reason, the proteins in yogurt are often called "predigested."
9. Yogurt can lower cholesterol. There are a few studies that have shown that yogurt can reduce the blood cholesterol.
10. Yogurt is a "growth food." Two nutritional properties of yogurt may help children with intestinal absorption problems grow: the easier digestibility of the proteins and the fact that the lactic acid in yogurt increases the absorption of minerals.
Osteoporosis:
Osteoporosis is a disease of the bones and increases the risk in a bone fracture. The combination of calcium and vitamin D found in yogurt makes it especially beneficial to those suffering from osteoporosis. The calcium in yogurt helps strengthens the bones, while the vitamin D helps the body with calcium absorption.
Like cheese, yogurt is a good dairy option for those with lactose intolerance. Yogurt contains lower amounts of lactose than milk because the cultures help to digest the lactose.
To summarize, Yogurt’s live cultures, or “good bacteria,” which turn milk into lactic acid, supply most of this food's health benefits. Yogurt benefits a number of the body's systems, both inside and out.
