Sour plum soup cannot actually remove fat. The acidity or alkalinity of food does not affect the acidity or alkalinity of the human body. Daily intake of large amounts of acidic food, acidic metabolites increase, will affect the body's acid-base balance. However, in reality, the body will not easily become alkaline just because it eats an extra pound of alkaline food (such as umeboshi) one day. The body itself has a very powerful regulatory system to maintain the acid-base balance and keep the body fluids in a very precise range of weak alkalinity. For normal people, it is difficult to change the acidity or alkalinity of the body with a normal diet. Thus, it is very unreliable to try to change the pH of the body by drinking sour plum soup food. Simply put, it is the main ingredients of sour plum soup that are at work. Both ume and hawthorn have the effect of lifting fats, while tangerine peel can inhibit the conversion of sugar into fat. Perhaps more importantly, it is important to understand that sour plum soup is sugary, so why is it not fattening but also fat-reducing. First of all, it is important to understand that sugar is not the same as fat, or that sugar absorbed into the body is not necessarily converted into fat. In fact, absorbed into the body of sugar, will first be used as a source of energy to maintain the body's vital activities and consumed, and this is often not enough, and then need to mobilize proteins and fats (from lipid-based foods) to provide energy. Only large amounts of excess sugars cause a surplus that is converted to fat. Secondly, except for the high sugar content of soft drinks, the sugar content of general beverages, including sour plum soup, is not considerable. The small amount of sugar and calories contained in the hundreds of milliliters consumed in a day can be offset by the following feedback regulation of the body: 1. The human body's sense of hunger is mainly derived from the neurological reflexes to insufficient blood glucose, and the elevation of blood glucose following the consumption of beverages reduces the appetite, decreases food intake and digestion, and weakens the body's ability to absorb carbohydrates (sugars). 2. Sugar absorption process itself will stimulate the body to increase the current body metabolic rate (increased body temperature when eating), and inertia to maintain for a period of time, this period of time to increase the calorie consumption is likely to offset a small amount of sugar calories. 3, acidic plus sweetness stimulation, will stimulate the body to secrete hormones such as adrenaline, accelerate the metabolism. Third, sour plum soup is sour to drink, but it is actually alkaline food, drinking helps to neutralize the acidic effect of sugars and lipids, accelerate their metabolic decomposition.
