Eat more leafy greens, drink 8 glasses of water a day …… These are not wrong for healthy people or most people, is a health concept, but due to the exaggeration of propaganda or the way people understand out of context, these ideas are most likely to be misinterpreted. 1, walking is the easiest way to exercise. Studies have shown that small particles in the air can increase the chances of a heart attack. When experiencing hazy weather, heart patients should try to be active indoors and turn on the air conditioning – it can reduce indoor pollutant levels by 50%. 2. Swimming is the best form of aerobic exercise. People who suffer from asthma should not believe this claim because chlorine in swimming pools can trigger asthma attacks. Also, parents should not bring their children with allergies under the age of 7 into the pool. 3. You should eat more leafy greens. People who are taking the blood thinner warfarin are advised not to consume too many leafy greens in a day. Warfarin functions by blocking vitamin K activity, thus avoiding blood clot formation. And spinach, lettuce and other leafy greens are rich in vitamin K, eating too much will affect the effectiveness of the drug. 4, drink enough 8 glasses of water every day. Nearly 20% of the body’s water intake is through food. Excessive water consumption can disrupt the water-salt balance in the body and cause “water poisoning”, which may even lead to death. If you find that your urine color has become lighter, it means that the intake of water has been sufficient. 5, once you find that your blood pressure is a little high, you think it should be lowered as much as possible. Blood pressure down to 120/80 mmHg does help reduce the chance of a heart attack or stroke. But a study of 22,000 patients with coronary heart disease showed that diastolic blood pressure dropped below 70 mmHg increased the chances of heart attack or even death by a factor of one. 6, completely from the food intake of nutrients. For vegetarians, some essential nutrients can only be achieved by taking nutritional supplements, such as vitamin D and vitamin B12. If you often feel weak, it is best to check to see if it is a deficiency of iron.
