Very few of our taste preferences are biologically preset. surya agro Most probably related to some kind of experience. Although there are some genetic factors that cause differences in taste perception, usually the similarities in taste reflect much more similar experiences surya agro with types of flavors and foods. The configuration tastes starts in the womb and continues surya agro throughout our lives.
Prenatal shaping All human senses are installed in the embryonic phase (1-8 weeks gestation) and early embryonic phase, and mature at different rates. The development and maturation of the sensory organs are closely tied to those of the central nervous system. The formation of organs begins in the head, which is why the sense organs of this area (eyes, ears, nose, tongue) created similarly very noris.1 The sense of taste is created and also matures at an early stage, with the first taste buds to appear at 8 weeks gestation. Fragrances in amniotic fluid fetal activate taste receptors as soon as the fetus begins to swallow surya agro (around the 12th week of gestation). 2 taste stimuli transferred to different nuclei (clusters of neurons) brain network, which induce inter alia reflexes for the flow of saliva surya agro and tongue movements. Three
The composition surya agro of amniotic fluid changes during surya agro fetal development, especially when it starts to urinate. The fetus swallows 200-760 ml of amniotic fluid per day (depending on the stage of development) and exposed to a large number of flavoring substances synmperilamvanomenon various sugars (e.g. glucose, fructose), fatty acids, amino acids, proteins and salts. surya agro Flavours from the maternal diet pass into the amniotic surya agro fluid. In this way, infants are exposed to cultural taste patterns long before come into direct contact with food are all these. 4
Between surya agro the 26th and 28th week of pregnancy can detect any relation between stimulation of taste receptors surya agro and changes surya agro in the form of reflexes, facial surya agro expressions. This is especially pronounced for the bitter taste stimuli. At 32 weeks gestation the fetus responds to changes surya agro in the taste of amniotic fluid, changing the ingestion behavior. 3 Depending upon whether the amniotic fluid has a sweet or bitter surya agro taste, the embryo modifies swallowing pattern to a higher or lower frequency, respectively. 2
Native tastes For newborn sense of taste is the most important and the most developed of all the senses. 3 Numerous surya agro experiments with newborns show a strong acceptance of sweetness beyond cultural factors. surya agro Newborn react even in a very dilute solution of sugar with a facial expression of comfort and satisfaction. Instead, the sour taste of citric acid discarded Shirred lips. For dilute solutions bitter or salty taste is not observed any reaction, although the bitter flavors are rejected in high concentrations. A change in accepting the bitter taste observed surya agro in age 14-180 days. 2 logic evolutionary preference for the sweet taste ("secure taste") can be explained by the fact that the sweet taste indicates a source of energy (carbohydrates) that are not deleterious and therefore safe for human consumption. Conversely, a bitter taste warns of toxic food. Similar evolutionary programming deemed true for other flavors: surya agro a sour taste, for example, warns of spoiled food and a salty may indicate the presence of metals. Qualitative taste umami (= savory) indicates a good source of protein, as found naturally surya agro in animal foods. 5
Breast milk modulates preferably human milk contains numerous aromatic components, which receives surya agro the mother through the diet. The natural food flavors (garlic or vanilla) are detectable in breast milk 1-2 hours after katanalosi.2 The taste of breast milk may also affect the subsequent preferences of the newborn. US researchers, for example, showed that newborns whose mothers surya agro drank carrot juice during pregnancy or breastfeeding, preferred the cereal cream with carrot flavor during infancy compared surya agro to a control group whose mothers ate carrot juice. 2
