Commercial urea is added to milk to increase non-protein nitrogen content (Sharma et al. 2012). ... Both peroxides and detergents in milk can cause gastro-intestinal complications, which can lead to gastritis and inflammation of the intestine.

Pros of soy milk It's a good source of potassium and can be fortified with vitamins A, B-12, and D, as well as calcium. It contains as much protein as cow's milk, yet is lower in calories than whole milk and about equal to the calories in 1 percent or 2 percent milk. It contains very little saturated fat.

Urea is found in the urine or uric acid of most living organisms, and is written as chemical formula (NH2)2CO. This compound is highly soluble in water, due to its extensive hydrogen bonding. ... Urea is difficult to dissolve when too little water is present, and it will be too diluted if too much water is used.

Urea and Uric Acid: Urea is produced from the conversion of ammonia. Ammonia comes from the breakdown of amino acids which can be dangerous if too much ammonia is in the body. Uric acid is produced from purines in foods after it has been digested.

Food manufacturers produce lactose-free milk by adding lactase to regular cow's milk. Lactase is an enzyme produced by people who tolerate dairy products, which breaks down lactose in the body.

Summary Milk contains a variety of nutrients that benefit bone health, such as calcium, vitamin D, phosphorus and magnesium. Studies suggest that consuming milk and dairy products may prevent osteoporosis and reduce the risk of fractures.

Whereas lactose is a carbohydrate, whey and casein are the protein components of milk. The body uses a protease enzyme to break them down for digestion and absorption.

Mechanism of action. Urea in low doses is a humectant while at high doses (above 20%) it causes breakdown of protein in the skin. Urea dissolves the intercellular matrix of the cells of the stratum corneum, promoting desquamation of scaly skin, eventually resulting in softening of hyperkeratotic areas.

Skim milk, 1 percent milk, 2 percent milk and whole milk all have the same amount of protein, calcium, vitamins and minerals. Vitamin D is added to all of them. The amount of fat is the only difference between them, and it's a big difference.

There will be slightly more carbohydrate, protein, sugar and calcium. It is also important to remember the 'sugar' in milk is not 'added' sugar. It is a natural, low glycaemic index sugar, called lactose. Sugar is not added to plain skim milk.

DO: Drink Milk Does a tall glass of cold milk or some frozen yogurt sound good? Go ahead. Studies show that drinking low-fat milk and eating low-fat dairy can reduce your uric acid levels and risk of a gout attack. The proteins found in milk promote excretion of uric acid in the urine.

Summary. Urea is a waste product of metabolism that is excreted by the kidneys in urine. Kidney disease is associated with reduced urea excretion and consequent rise in blood concentration.

The principal constituents of milk are water, fat, proteins, lactose (milk sugar) and minerals (salts). Milk also contains trace amounts of other substances such as pigments, enzymes, vitamins, phospholipids (substances with fatlike properties), and gases.

Cows produce milk for the same reason humans do—to feed their babies! When a cow's milk is taken from her to be sold to humans or made into cheese, it means that her baby can't drink it. Instead, calves are fed milk replacers that are completely unnatural.

Some of the major adulterants in milk having serious adverse health effect are urea, formalin, detergents, ammonium sulphate, boric acid, caustic soda, benzoic acid, salicylic acid, hydrogen peroxide, sugars and melamine.

Companies that use this diluted milk in liquid and powdered infant formula check the protein level of the raw milk by testing it for nitrogen content. If melamine has been added to the milk it will show a good level of nitrogen and therefore the milk will pass muster as being protein rich.

In cow's milk and human breast milk, the sugar comes primarily from lactose, also known as milk sugar. Nondairy milks, including oat, coconut, rice, and soy milk, contain other simple sugars, such as fructose (fruit sugar), galactose, glucose, sucrose, or maltose.
