This app is basically built to help you to maintain your diet in regular bases.Good nutrition is an important part of leading a healthy lifestyle. Combined with physical activity, your diet can help you to reach and maintain a healthy weight, reduce your risk of chronic diseases (like heart disease and cancer), and promote your overall health.The number of calories in a food is a measurement of the amount of energy stored in that food. Your body uses calories from food for walking, thinking, breathing, and other important functions.

The average person needs to eat about 2,000 calories every day to maintain their weight. However, a person’s specific daily calorie intake can vary depending on their age, gender, and physical activity level. Men generally need more calories than women, and people who exercise need more calories than people who don’t.

The following examples of daily calorie intake are based on United States Department of Agriculture (USDA) guidelines:

children ages 2 to 8 years: 1,000 to 1,400 calories

girls ages 9 to 13 years: 1,400 to 1,600 calories

boys ages 9 to 13 years: 1,600 to 2,000 calories

active women ages 14 to 30 years: 2,400 calories

sedentary women ages 14 to 30 years: 1,800 to 2,000 calories

active men ages 14 to 30 years: 2,800 to 3,200 calories

sedentary men ages 14 to 30 years: 2,000 to 2,600 calories

active men and women over 30 years: 2,000 to 3,000 calories

sedentary men and women over 30 years: 1,600 to 2,400 calories

The source of your daily calories is just as important as the number of calories you consume. You should limit your consumption of empty calories, meaning those that provide little or no nutritional value. The USDA defines empty calories as calories that come from sugars and solid fats, such as butter and shortening.

A balanced diet is important because your organs and tissues need proper nutrition to work effectively. Without good nutrition, your body is more prone to disease, infection, fatigue, and poor performance. Children with a poor diet run the risk of growth and developmental problems and poor academic performance, and bad eating habits can persist for the rest of their lives.

Rising levels of obesity and diabetes in America are prime examples of the effects of a poor diet and a lack of exercise. The Center for Science in the Public Interest reports that 4 of the top 10 leading causes of death in the United States are directly influenced by diet. These are:

Fruits

Besides being a great source of nutrition, fruits make tasty snacks. Choose fruits that are in season in your area. They’re fresher and provide the most nutrients.

Fruits are high in sugar. This sugar is natural, though, so fruit can still be a better choice for you than other foods with added sugar. If you’re watching your sugar intake or have a condition such as diabetes, you may want to opt for low-sugar fruits. Read on to learn about the 11 best low-sugar fruits, from citrus to peaches. People who are watching their carbohydrate intake may reach for fruits such as melons and avocadoes.

Vegetables

Vegetables are primary sources of essential vitamins and minerals. Dark, leafy greens generally contain the most nutrition and can be eaten at every meal. Eating a variety of vegetables will help you obtain the bountiful nutrients that all vegetables provide.

Grains

According to the USDA, Americans consume refined white flour more than any other grain. Refined white flour has poor nutritional value because the hull of the grain, or outer shell, is removed during the refining process.
