According to the US Science and Technology Daily, economists at the University of Iowa School of Business found that the free breakfast provided by the school helps students from low-income families achieve better academic results. For children from low-income families who participate in the US Department of Agriculture School Breakfast Program, their math, science, and reading scores are higher than those who do not participate in the program.
The US federal government’s free breakfast for children from low-income families began in 1966. If some schools have a certain percentage of children from low-income families, the local school district is required to provide a subsidized breakfast. By examining the academic performance of these school students, the researchers found that students who enjoyed free breakfast had significantly better academic performance than those who did not have free breakfast.
The researchers point out that a nutritious breakfast gives these students more nutrients, good body and brain development, which helps them achieve better academic performance in school. This is a very effective health management. Measures.
Hidden hunger specifically refers to the loss of two major types of nutrients, one is vitamins and the other is minerals. The serious lack of these two types of nutrients can cause illness, even if the undetected mild lack, it will affect people’s intelligence level, labor ability and body immunity.
Iodine deficiency leads to stagnation. Iodine deficiency can easily lead to goiter (commonly known as “big neck disease”), and it can also cause stagnation, manifested as low length and loss of intelligence.
Iron deficiency induces anemia. Iron is an important source of red blood cells in the blood. If iron is deficient, red blood cells are reduced, and oxygen carrying capacity is reduced. In addition to reducing the body’s resistance, it is easy to infect the disease and will reduce people’s attention. The data shows that one in every five people in China is anemia, mostly women, children and the elderly.
Vitamin A deficiency is easy to blind at night. Vitamin A deficiency affects the immune system and makes the body’s resistance to viruses such as flu and measles worse. In addition, the optic nerve will also be affected, leading to night blindness and even blindness.
Zinc deficiency makes people feel weaker. Zinc deficiency can reduce immunity and also have a great impact on taste. In the absence of zinc, because the food is not fragrant, the food intake will decrease, and it is easy to face the yellow muscle.
Selenium deficiency is not good for heart health. Selenium is an antioxidant nutrient that is especially important for heart health. For example, Keshan disease, which was prevalent in Xichang, Sichuan, and Keshan in the northeast, both old and young, died of sudden heart problems, which has a lot to do with selenium deficiency.
In addition, calcium deficiency is easy to cause osteoporosis, lack of folic acid often causes birth defects… Many people think that overweight and obese people have excess nutrients, which is wrong. Overweight and obesity are high-risk groups of hidden hunger. Most of them are excessive intake of energy nutrients, but they may lack micronutrients, which will exacerbate chronic diseases such as diabetes and high blood pressure.
A new study published in the American journal Psychology pointed out that eating low-glycemic index foods for breakfast can help improve learning ability.
In the new study, Dr. Matthew T. Gallotte of Florida State University and his colleagues randomly divided a group of students into three groups. The first group ate healthy low-glycemic index breakfast (such as eggs and oatmeal). And the fruit, etc.), the second group eats high glycemic index breakfast (such as muffins and doughnuts, etc.), the third group does not eat breakfast.
Overall, it was found that students who ate low glycemic index breakfast performed better from 8:00 to 10:30. Students who ate high-glycemic index breakfasts had good grades at first, but by 10:30, learning performance and attention were significantly reduced. Students who do not eat breakfast perform the worst. Interestingly, after the students ate the same healthy snacks, the three groups of differences apparently disappeared. Dr. Gillette said the new study showed that glucose plays an important role in controlling behavioral abilities. In order for the body to continue to get healthy levels of glucose, breakfast should adhere to low glycemic index foods.
Low glycemic index foods mainly include the following five categories: 1. Lean meat protein. It mainly includes beef, poultry, pork, fish and eggs. 2. nut. Especially nuts rich in omega-3 fatty acids, such as walnuts, pecans and cashews. 3. For fresh fruit, the best choices are: bananas, blueberries, apples and cherries. 4. vegetables. Vegetables such as spinach and pakchoi are very healthy and enhance their willpower. 5. Coarse grains. Coarse grains such as oatmeal, red beans, and mung beans help control blood sugar.
