There is clear evidence that folic acid deficiency in pregnancy is related to the occurrence of neural tube defects in newborns.
These malformations are caused by incomplete closure of some regions of the neural tube and include anencephaly and spina bifida encefalocete (with effects ranging from death to paralysis more or less important or urinary incontinence).
They are probably due to the lack of folic exist, there is not enough DNA for normal development of the embryo, and consequently a defect in neural tube closure.
It has been shown that supplementation with folic acid before conception and during early pregnancy decreases the incidence of neural tube defects in newborns. Because of this, it is recommended that all women in a position to become pregnant should take the order of 400 micrograms / day of folic.

Since about 50 years ago showed that the decay could be controlled with the use of fluoride, many preparations have appeared that contain it. Some are for professional use and some not.
Fluoride has three very beneficial effects on teeth:
- Increases the resistance of enamel: Applying fluoride on the teeth, it reacts with calcium in them, forming calcium fluoride. In this way, the fluorine reacts with the crystals of tooth enamel (hydroxyapatite), resulting in a compound that greatly increases the resistance of enamel.
- It helps remineralisation: Fluoride contributes to the remineralization of the tooth, by encouraging entry into the structure of calcium and phosphate ions. This is because the fluoride has negative charge and attracts the calcium and phosphate whose charge is positive.
- Has antibacterial action: Fluoride has antibacterial action attacking the bacteria that colonize the tooth surface.

A team of Spanish scientists has created a green chocolate that instantly kills the appetite. The novelty is a mixture of cocoa, jojoba and spirulina (an algae), which according to its creators, the body produces naturally a feeling of fullness after eating just one or two chocolates of 15 grams each, picked up the BBC today .
The end result, which received the approval of the Agro-Food Technology Institute of Spain, is a combination of biochemical that stimulates the production of phenylalanine, an amino acid in the brain that activates neurotransmitters such as cholecystokinin (CKK, by its initials in English ).
The CKK, a gastrointestinal hormone, stimulates enzymes segregation and sends messages to the brain and the digestive system to signal that the body is already filled, thus cutting your appetite. Professor of Chemistry at the University of Alicante and one of the creators of the new product, Armando Yañez, said that this chocolate is “so simple and tasty as any candy, with the difference that helps the body know when to stop. With him is just greed, “he concluded.
