The Japanese government provides health care for everyone as it is compulsory. Although it isn't free, it is rather inexpensive. Japanese citizens pay 30% of their medical bills themselves, bills which are closely regulated by the state so that they never become unaffordable. The JHI (Japanese health info) recommends bringing between 10,000-15,000 yen with you for an emergency room visit if you're covered by health insurance. The average cost of a doctor’s room visit is 5000-10,000 yen. And lastly the average cost of public health insurance for one person is around 5% of your salary. In japan there are more than 53,000 pharmacies, almost 42 per 100,000 people. There are just under 8500 hospitals! The traditional Japanese diet is largely fresh and unprocessed, with very little refined foods and sugar. A study showed those who stuck to closer to the Japanese dietary guidelines – a diet high in grains and vegetables, with moderate amounts of animal products and soy but minimal dairy and fruit – had a reduced risk of dying early from heart disease or stroke. As their diet is traditionally high in soy and fish this may also play a significant role in reduced risk of cardiovascular disease. The Japanese also have the lowest rates of obesity amongst men and women as well as long life expectancy.

Yemen is suffering the largest humanitarian crisis in the world as we speak. With ongoing war since 2015 and almost no healthcare, life expectancy there is very low at an average of 66.19 years. Dr Anisa works at one of the only clinics which provide free healthcare and people travel for many hours just to see her every day. Like many doctors in Yemen, she hasn't been paid in years. The public health system in Yemen suffers from many problems in both structure and organization. Low morale, quality of care, shortage of medicines, lack of a referral system and funding all contribute to the current state of the Yemeni public health system. The main reason for poverty in Yemen is lack of basic resources such as education, clean food and water and healthcare.

A way for the national government to improve life expectancy is to adjust the diet, however this would be difficult as the overall population of Yemen are living in poor conditions with no food/ clean water or any money at all, so they aren't able to provide themselves with a balanced diet. The NHS says a balanced diet is an important part of maintaining good health and can help you feel your best. This means eating a wide variety of foods in the right proportions and consuming the right amount of food and drink to achieve and maintain a healthy body weight.
