Flour and yeast are the basic materials for making bread, which seems simple. Do you know the difference between "natural yeast" and "commercial yeast"? Because natural yeast needs time to cultivate and experienced baker to operate, the quality of finished products is difficult to control, so many businesses will use commercial yeast. Commercial yeast also comes from natural yeast, but it can be propagated in large quantities after screening and culture by manufacturers, so it can also be fermented in a short time. It only takes 1 hour to make a batch of bread, which is of course the first choice to increase bread production.
Commercial yeast is also cultivated from natural yeast, and there is no explicit provision in China. Many businesses that use commercial yeast may also claim to use natural yeast. Generally speaking, if the dough fermentation time is too short and the fermentation is not complete, it is easy to swell when baked into bread. If the baked bread collapses, the appearance and taste are not good, and merchants can easily make up for it with artificial additives. If commercial yeast bread is operated by unscrupulous merchants, it is easy to make this unhealthy bread.
Q: So is bread with natural yeast necessarily healthy?
Natural yeast bread or hydrogenated vegetable oil bread with high sugar and oil are also unhealthy.
Dr. Chen Junxu once wrote in If you eat wrong, of course you will get sick! It is pointed out in the book that hydrogenated vegetable oil is often used in modern diet, that is, hydrogen atoms, seasonings, artificial spices and vegetarianism are added to vegetable oil which is liquid at room temperature, so that vegetable oil presents a creamy texture. Margarine "Milk Marlene" and vegetable butter are hydrogenated vegetable oils. Many people mistakenly think that vegetable oil is healthier, but it is not.
Because vegetable oil adds two hydrogen atoms, it changes the original "cis fatty acid" into "trans fatty acid". I believe many people will know that it can't be a healthy food when they see "trans fatty acid", not to mention there are many unknown additives in the manufacturing process. However, the characteristics of hydrogenated vegetable oil, such as stability and non-oxidation, make it very popular with merchants. Whether it is bread, cake or fried food, it may contain hydrogenated oil.
Dr. Chen Junxu quoted Health Canada's experiment, which showed that if mother ate many cakes and bread made of margarine and ghee, breast milk might contain more than 7% trans fatty acids! Trans fatty acids are unacceptable in the human body, which will lead to physiological dysfunction in children since childhood, such as arteriosclerosis and stroke caused by blood vessel rupture, and the risk of cancer will also increase. Don't be careless Q: Can you often eat bread with all natural ingredients?
A. Bread is also a kind of starchy food. Every piece of bread is like dropping sugar and oil on white rice!
If you think that eating only bread should not make you fat, you can eat bread without additives as three meals. Dr. Chen Xianchang suggested that you have a taste. Because bread, like rice and noodles, is refined starch food and contains a lot of sugar. Excessive consumption will increase blood sugar and neutral fat, which is also harmful to health.
If you really want to eat bread, pharmacist Wu Zongxiu thinks that you should try to choose organic certified food, which can reduce the chance of eating unknown food additives. If you want to prevent the blood sugar from rising too fast after eating bread, you should choose less delicate bread such as whole wheat and French bread, and eat it in moderation to reduce the burden on your body.
