Q. If vitamin A is fat-soluble; does that mean it's found in foods that contain fat?
A. Yes. Vitamin A occurs naturally only in foods of animal origin, such as liver, which is the storage place for vitamin A in animals and humans; some seafood; butter; whole milk and egg yolks. This form of vitamin A is usually called pre-formed vitamin A, or retinol. Retinol is also added to skim and low-fat milk.
The plant occurs in several parts of India, chiefly in the drier parts of the peninsula, and is usually cultivated in hedges. It is also cultivated for commercial purposes, in Punjab, Gujarat, Madhya Pradesh and Rajasthan.
The leaves contain a glucosidal coloring matter and hennotanic acid. On petroleum ether extraction, the seeds of the plant yield a viscous oil containing behenvc, arachidic, stearic, palmitic, oleic and linoleic acids.
Q. I know that a compound of fluorine, called a fluoride, is often added to some brands of toothpaste, and even to some water supplies to help reduce cavities. Does it really work for that?
A. Yes. Tooth decay rates are much higher than average in areas in which the drinking water is naturally low in fluorine. When adequate amounts of fluoride are incorporated into tooth enamel, the rate of tooth decay is substantially reduced. Studies show that it works not only for children's teeth, but for adults, too.
Climate change poses a wide range of risks to population health - risks that will increase in future decades, often to critical levels, if global climate change continues on its current trajectory.
The majority of the adverse effects of climate change are experienced by poor and low-income communities around the world, who have much higher levels of vulnerability to environmental determinants of health, wealth and other factors, and much lower levels of capacity available for coping with environmental change. A report on the global human impact of climate change published by the Global Humanitarian Forum.

Detox with lemon
Lemon juice is a great flavor enhancer and mixed with hot water is a really healthy (and detoxifying) alternative to heavily caffeinated hot drinks. Get twice as much juice out of your lemons by heating in the oven or hot water, or by rolling until slightly soft, before squeezing.

Geneva (AFP) - The number of people with Ebola is set to hit 10,000 in West Africa, the World Health Organization said, as the scramble to find a cure gathered pace.
The UN's public health body said 9,936 people in Guinea, Liberia and Sierra Leone -- the three countries at the epicentre of the world's worst-ever Ebola epidemic -- have contracted the disease. In total, 4,877 people have so far died.
An Obama administration health official said Sunday that U.S. protocols on Ebola failed because they originally were intended for African field hospitals, while the White House came under another round of attacks for its refusal to restrict travel from nations suffering epidemic outbreaks.
Dr. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, said the original Centers for Disease Control and Prevention instructions for dealing with the virus were taken from the World Health Organization’s protocol for Africa, where conditions are much different from those in U.S. hospitals.
After a baby is born and the umbilical cord is cut, some blood remains in the blood vessels of the placenta and the portion of the umbilical cord that remains attached to it. After birth, the baby no longer needs this extra blood. This blood is called placental blood or umbilical cord blood: "cord blood" for short.
Cord blood contains all the normal elements of blood - red blood cells, white blood cells, platelets and plasma. But it is also rich in hematopoietic (blood-forming) stem cells, similar to those found in bone marrow. This is why cord blood can be used for transplantation as an alternative to bone marrow.
