The benefits of pregnant women eating nuts
Nuts are rich in unsaturated fats and other nutrients that help to improve blood sugar and insulin balance.
Eat more nuts can reduce the risk of sudden cardiac death and death from coronary heart disease;
Almonds from the United States have a good regulatory effect on lipids and apolipoprotein levels in patients with hyperlipidemia;
Eat more nuts can improve vision;
Nutty foods contain large amounts of unsaturated fatty acids. Eating nuts is beneficial to improving brain nutrition, especially for pregnant women and children.
What nutritious pregnant women eat
walnut. Walnut is the best product for Bunao. In order to express their praise for the function of walnuts, folk pregnant women have the concept of “parents eating walnuts and brainsâ€. It contains a lot of nutrients, such as DHA for baby brain development, calcium for bone development, and zinc, folic acid and so on. According to the determination: 1 kilogram of walnut is equivalent to 5 kilograms of eggs or 9 kilograms of fresh milk nutrition, and there is qi nourishing, warm lung Runchang effect. The structure of its nutrient is very beneficial to the brain development of the embryo. Therefore, pregnant women should eat 2 to 3 walnuts per day. Chewing walnuts can also prevent dentin hypersensitivity.
Melon seeds. We can often see sunflower seeds, pumpkin seeds and watermelon seeds. It is both cheap and healthy and tasty. Eating more pumpkin seeds can prevent kidney stone disease. Watermelon seeds are sweet and cold. It has beneficial lungs, intestines, hemostasis, stomach and other effects; the unsaturated fatty acids contained in sunflower seeds can play a role. Lower cholesterol.
hazelnut. Contains unsaturated fatty acids, and rich in phosphorus, iron, potassium and other minerals, as well as vitamin A, vitamin B1, B2, niacin, often eat eyesight, brain.
almond. Cough and asthma, laxative, effective prevention of constipation during pregnancy. Note that almonds are small poisoned and should not be eaten. It is recommended to eat 3-5 pieces a day.
Two nuts can not eat
"Cosmetic" nuts are detrimental to health. Some melon seed producers have abused industrial pigments and industrial waxes in their production. Many non-food pigments are highly carcinogenic. Some processors also use chemicals such as bleaching agents to cosmetically treat the nuts and eliminate variegated spots. This often leads to nuts containing excessive amounts of harmful chemicals. In particular, cracked nuts in pistachio nuts are more likely to accumulate harmful treatment chemicals in nuts. These cosmetic chemicals are very harmful to human health.
Nuts that are too heavy are prone to deterioration. Nuts on the market have a variety of flavors. Some people like salty, others like cream, others like green tea, and others like five flavors. In general, the heavier the taste, the more often salt is added. Secondly, many nuts with heavy flavors and rich aromas add flavors, saccharin, and other substances to the processing. The creamy seeds also contain margarine, which is not good for the body; once again, the nuts that taste more are delicious. The more likely it is to hide spoiled nuts.
Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.
The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
