Stupidity is the cause

Everyone's IQ is different. Some people are very smart, but some people are slow to react. In fact, this is affected by many factors, including genetic factors. Generally speaking, if the parents have a high IQ, then the child's IQ will usually not be low. The child's diet and health problems, physical health, growth environment, and usual use of medicines will also affect intelligence.

1. Genetics: Generally speaking, if parents have high IQs, their children’s IQs will not be low. This genetic factor is also reflected in blood relationships. If both parents are locals, the average IQ of their children is 102; while the IQ of children born to parents who marry from different provinces is 109; if the parents are cousins, the number of children with low IQ increases significantly.

2. Breast milk: Breast milk contains a variety of active substances that promote children's intellectual development, such as DHA. In particular, taurine, which has an important influence on intellectual development, is 10 times higher than in milk. According to a survey, children who grow up with breast milk have an IQ about 3-10 points higher than those who grow up with milk substitutes.

3. Diet: People who eat too much meat or are greedy will have reduced intelligence. The intelligence of people who skip breakfast will be affected. This is because the protein, sugar, vitamins and trace elements consumed in breakfast are all important components for brain health.

4. Obesity: About 20% of people whose weight exceeds normal level will have lower vision, hearing and ability to absorb knowledge. This is because too much fat enters the brain of obese children, which hinders the development of nerve cells and the proliferation of nerve fibers.

5. Growth environment: People who live in a boring environment, such as abandoned babies, who do not receive maternal love and a good education, will have a lower IQ. According to research, the average IQ of this type of people is only 60.5 at the age of 3. On the contrary, the average IQ of 3-year-old children in a good growth environment is 91.8.

6. Drugs: Many types of drugs can affect a person’s intelligence. For example, long-term use of anti-epileptic drugs can lead to a low IQ. After stopping the drugs for several years, the IQ will improve.
