1. Meaning: Non-alcoholic beverage, also known as Soft Drink, is a kind of beverage with no alcohol or alcohol content below 0.5%. ?

2. Specific description: Soft drinks are mainly made of mineral water or drinking water, fruit juice, vegetable juice or extracts from flowers, leaves and roots of some plants, and these drinks belong to the category of soft drinks.

3. For example, soft drinks include carbonated drinks (fruit juice, fruity, cola, low-calorie and other types, excluding drinks that produce carbon dioxide by fermentation), fruit juice (pulp) and fruit juice drinks, milk-containing drinks, vegetable juice drinks, vegetable protein drinks, bottled drinking water drinks, tea drinks (tea drinks, fruit juice tea drinks and other tea drinks), solid drinks and other tea drinks.

4. Function: Replenish human body moisture.

Second, hard drinks (alcoholic drinks)?

1. Meaning: Hard drinks refer to drinks containing alcohol, including white wine, brandy, whisky, vodka, felt wine, rum, tequila, liqueur, aperitif, various special drinks, cocktails, wine, beer, etc. As opposed to soft drinks, those containing alcohol are called hard drinks.

2. Does the raw material include drinking water or mineral water, fruit juice, vegetable juice or roots and stems of plants? , leaves? Extracts from flowers and fruits.

* * * Same point: corrosive.

Differences at home and abroad: Hard drinks mainly contain beer, as well as fruit wine such as wine, which is completely different from the brewing method in China. As for soft drinks, such as soda and fruit tea, they have different tastes and different preparation methods. But it is definitely very different from the method of making drinks in China. China drinks pay attention to mellow and strong taste; Western drinks, on the other hand, pay attention to the difference in taste and the irritation of taste.

(1) Benefits: A study by neurologists at the University of Scotland in Glasgow found that drinking 2 cans of carbonated drinks a day can improve people's memory by 20% and effectively prevent Alzheimer's disease. Because the hippocampus in the brain will become very active under the stimulation of rising blood sugar, the hippocampus in Alzheimer's patients will decline and the hippocampus will shrink.

(2) Disadvantages: With the continuous improvement of people's quality of life and the change of eating patterns, the consumption of soft drinks (that is, non-alcoholic drinks) and the intake of acidic diets are increasing day by day. Soft drinks are mostly acidic, and their pH values are between 1-6. As the starting point and portal of digestive tract, teeth will inevitably suffer from the corrosion of acidic drinks for a long time.

(C) the corrosiveness of soft drinks to teeth

1. In the early stage of acid erosion?

The main manifestations are slight demineralization of glossy surface, loss of natural texture of enamel and smooth mirror-like changes of tooth surface. At this time, patients often do not feel symptoms.

2. With the aggravation of acid etching?

There will be shallow disc-shaped defects on the smooth enamel surface, groove-shaped defects on the incisal crest of the anterior teeth, thinning of the incisal margin, dentin exposure and so on.

In addition, acid etching can also cause dentine hypersensitivity, and even pulpitis. In severe cases, it may also cause diseases such as broken teeth, premature loss, disordered occlusion, decreased face height and disorder of temporomandibular joint, which will affect chewing function and aesthetics, and will also have adverse effects on patients' physiology and psychology.

So for the sake of oral health, we must do it.

Adjust the oral environment to follow healthier living habits and reduce exogenous acids entering the oral cavity, such as: reducing the intake frequency of acidic diet; Use straws when drinking beverages to shorten the contact time between acid and teeth; Rinse your mouth with water or soda water after drinking.

Reduce the corrosive ability of acid? For example, if the existing beverage formula is improved, macromolecular sugar substitutes (such as xylitol and sorbitol) with low corrosiveness are used to replace sugar sweeteners with strong corrosiveness.
