I will now review how the voice relates to specific kinds of drinks, in a series.
Good drinks for the voice:Part9 Orange Juice
The orange is not only ingested in fruit form, it can also be made into juice. There are many types of oranges in the citrus family. Such common types are navel, blood, mandarin, valencia and clementines. Oranges are refreshing and are a good source of vitamins A & C. Many oranges contain seeds. The proper name for an orange seed is, pip. Oranges contain pulp as well, also known as the juice vesicles of the fruit, which hold the juice in the fruit. The pulp has cells which have small membranes, and protect the seeds of the fruit. Having pulp in your orange juice is simply a personal preference, and many people choose orange juice where the pulp has been filtered out. I’ve investigated orange juice with and without pulp, and analyzed how it can relate to vocalization.
Do you feel like you have more or less sputum if you drink orange juice?
Many doctors claim that the content of orange juice encourages us to secret, serous fluid
(also known as serosal fluid). Serous fluid is typically pale yellow or transparent in color, and is contained inside our body cavities, saliva and blood. The saliva is made by the high viscoelasticity of sputum and the serous fluid. Serous fluid also comes from mixed glands, which contain both mucous and serous cells. Serous fluids are known to aid in assisting respiration, digestion, and excretion. The fluid allows the organs to slide without friction across the cavity walls and one another, as they carry out their routine functions. This freedom of movement is vital for mobile organ health.
If you eat an orange or drink orange juice, you will increase the serous fluid in the saliva. The fruit or juice is not overly sticky in the throat and is good for singing.
Holistic medicine uses dry orange peels to stop coughing naturally instead of man made medicine.
I think this is also good for the voice.
On the contrary, there is also opinions that oranges and orange juice increase the viscoelasticity of the sputum. In that case, the saliva can become dry depending on the orange juice. (the percentages and concentrates of the juice available for purchase vary) It very well might increase the viscoelasticity of the sputum if sputum already exists in the throat, thus effecting our saliva.
Unfortunately, I do not know how the content of an orange effects the sputum but some people say, their sputum feels stickier than normal if they eat an orange or drink orange juice. I agree with their statement and believe that to be true.
