Do you eat apples in the morning on an empty stomach?
In fact, for healthy people, you can eat apples at any time. There is no harm in eating apples in the morning on an empty stomach. This is mainly because the ingredients in apples are not complicated and they are easily digestible. Generally, 100 g of apples contain 86 grams of water, protein 0.2 grams, fat 0.2 grams, carbohydrates (sugars) 13.5 grams, dietary fiber 1.2 grams, Vitamin C4 milligrams, calcium 4 milligrams, potassium 119 milligrams and so on.
However, for those who have a bad stomach, it is best not to eat apples on an empty stomach. In particular, some gastrointestinal diseases, generally need to quit cold food, especially in the morning to eat an apple on an empty stomach, may cause stomach discomfort. In addition, for those who have blood sugar fluctuations. Apple's sugar content is about 13.5%, and mainly monosaccharides, absorption rate is high, eaten on an empty stomach, easily lead to fluctuations in blood sugar.
Eat Apple Notes
For ordinary healthy people, if there is no discomfort in eating apples in the morning on an empty stomach, the general problem is not significant. However, it is not recommended to eat it for a long period of time. After all, all kinds of acid and cold stimulation during the morning fasting have certain effects on the stomach and intestines. I suggest you eat apples like this:
1. People with a poor gastrointestinal tract do not recommend eating an apple on an empty stomach. You can drink hot porridge or the like in the morning.
2. Although peeling does not necessarily prevent the residue of pesticides, it is best for peeling apples that are too fresh and shiny or imported.
3. Time is tight, remember to sip slowly and slowly so as to facilitate digestion and absorption of nutrients;
4. It is advisable to use apple as a snack in the morning, which means that you need to eat on time in the morning;
5. If you have to eat an apple on an empty stomach in the morning, remember to have some breakfast, even if it's just a vegetable bag, a bowl of oatmeal, a corn, a cup of soy milk or an egg.
The benefits of eating apples
1. Eat apples to lose weight
A medium-sized apple contains only 60 to 100 kcal calories, is free of fat and does not contain sodium, and is a food that is no longer good for MM that is losing weight.
The nutrients and other phytochemicals in apples help fight cancer.
Women's obesity not only affects daily work, life, and beauty, but also is susceptible to cancer.
2. Eat an apple every day can also prevent stroke
Apple is good for health and is the patron saint of women's health. It is best to eat apples together with the skin, because compared with apple meat, apple flavonoids in the higher content, antioxidant activity is also strong, and can prevent stroke in middle-aged women.
However, due to the fact that Apple may use a lot of pesticides during the planting process, if it is not carefully cleaned during the consumption of apples, the fertilizers and pesticides remaining on the apple epidermis may cause various diseases such as leukemia. Therefore, if it is not guaranteed that Apple is natural, it will be the most Wash and peel well.
3. Apple contains a variety of effective prevention of heart disease
Apple is rich in folic acid, folic acid is the main component of vitamin B, it helps prevent the occurrence of heart disease.
Antioxidants in apples are good for the healthy operation of the heart. Apple's fiber, pectin, antioxidants and other ingredients can reduce bad cholesterol in the body and increase the level of good cholesterol, so that bad cholesterol blocks blood vessels later than normal. The earlier the bad cholesterol blocks blood vessels, the greater the risk of heart disease.
4. Eat more apples can prevent osteoporosis
Apples contain boron and manganese, minerals that enhance bone quality. A US study found that boron can significantly increase the concentration of estrogen and other compounds in the blood, which can effectively prevent calcium loss.
Medical experts believe that if menopause women can take 3 grams of boron per day, then their calcium loss rate can be reduced by 46%. Menopausal women eat more apples, which is beneficial to the absorption and utilization of calcium and prevention of osteoporosis.
5. Apple can neutralize human acidic substances
70% of illnesses occur in women with acidic body, while apples are alkaline foods. Eating apples can quickly neutralize excessive acidic substances (including acid produced by exercise and acidic foods such as fish, meat and eggs produced in the body). Acidic metabolites) enhance physical strength and disease resistance.
Preparation of Fenebute
1. Prepare the first intermediate
Benzaldehyde and ethyl acetoacetate into ethanol, stir at room temperature under the catalysis of organic alkali reaction with filter cake filtration after 45 ~ 50 h, after the completion of the filter with ethanol elution filter cake, dry cake solids, then ethanol filtrate concentrated to a quarter of the original volume, to cold, concentrate filtering alcohol washing, solid, merging two solid is the first intermediate; The mole ratio of benzaldehyde, ethyl acetoacetate and ethanol is 1:2.5 -3:12-15.
2. Prepare the second intermediate
The first intermediate is added to the mass concentration of 20% sodium hydroxide solution, and the reaction is stirred at 85-90°C for 2-5 hours. After filtration, the filter cake is used for filtration. After filtration, the filter cake is washed, the filtrate is combined and cooled, and the filtrate is cooled by stirring for 3h. Solid second intermediate; The mass ratio of the first intermediate to the sodium hydroxide solution is I: 1.8-2.0;
3. Prepare the third intermediate
The second intermediate was dissolved in pure acetic anhydride solution for reflux 3 ~ 5h. After the reflux, the acetic anhydride was concentrated and dissolved with toluene. After the dissolution, ammonia water was added, and the reaction took place at 60_65°C for 1 ~ 1.5 h. Filtrate, wash and dry the precipitated solid to get the solid third intermediate; The mass ratio of the second intermediate, pure acetic anhydride solution, toluene and ammonia water is 5:1-1.2:0.5-0.8:0.5-0.8;
4. Prepare Finebute
The third intermediate was dissolved in 25% sodium hydroxide solution and cooled to _5°C ~ 10°C. After cooling, sodium hypochlorite was added slowly within 15-20min for 1h reaction, followed by ice bath reaction of 0.5 ~ 1.5 h and water bath reaction of 0.5 ~ 1.5 h. Finally, the temperature was gradually increased to 60 ~ 80°C for 1-5 h, and the reaction was cooled again after completion. After cooling, hydrochloric acid was added in the ice water bath to adjust the PH to 2, and the decolorization was stirred at room temperature. After filtration, sodium hydroxide was added in the ice water bath to adjust the PH to 6-7, and the cooling was stirred for 2 hours. The mass ratio of the third intermediate, sodium hydroxide solution and sodium hypochlorite is 1.0:0.8-1.0:1.0-1.1.
