Background
When people become hurt or ill, our first thought is
immediately turn to medication, hoping for relief of our symptoms, who would seldom consider that the actual serious culprits are their poor lifestyle habits. As Dr. Mark Nelson reported in the American Journal of Hypertension, saying that “42% of patients with hypertension could get off their medication if they would follow simple lifestyle changes.”
So, what can we do in order to achieve healthy lifestyle?
1. A healthy diet
2. A modest exercise program
The most important one is to have a healthy diet, which is because thousands of studies have shown what we eat has a substantial effect on our overall health, and diet is closely related with the risk of having many diseases, such as diabetes, blood pressure, fatty, and other chronic degenerative diseases.
According to recent researches, more and more people begin to pay more attention to their health based on diet and nutrition. However, as the knowledge of nutrition is complex, some people come to dietitian for advices, and some choose to purchase nutrition supplements existing in the market. But, both of them are expensive and incontinent. As long as the changes of people’s attitudes toward food, restaurants and food supplier should also make corresponding changes.
Our proposed system is a PDA system. It is a portable, internet-enabled nutrition advisor, which can be used to keep track of user’s diet and workout history, generate warnings of harmful food based on users’ body information, and create periodic health reports. Also, this system will benefit restaurant and food suppliers, who are also our users, that they could retrieve customer order data for commercial usage.
This system will give nutrition advices from a balancing healthy diet perspective, which is observing comprehensive useful nutrition facts from various kinds of foods, and disputing all the harmful effects by calculating users’ personal health information.
Those calculating regulations comes from our analysis of standard academic nutrition formulas, they are:
1.
BMI (body mass index)
2.
Human Daily Calories Needs
3.
Suggested Nutrition Facts Daily Needs
And the healthy diet habit advices are based on standard academic nutrition rules, they are:
1.
Food Pyramid
2.
RDA (recommended dietary allowances)
3.
Diseases and medication food constraints
Our database comes from USDA (US government), FEHD (HK government), Supermarkets, Restaurants and Major Food Suppliers, who have high reliabilities, that user can use our system contentedly.
