Image Caption : Photo of a woman eating a healthy salad. Salad is any of a wide variety of dishes including green salads; vegetable salads; salads of pasta, legumes, or grains; mixed salads incorporating meat, poultry, or seafood; and fruit salads. They include a mixture of cold or hot foods, often including vegetables and/or fruits. One health benefit of consuming salad is an increase in fiber intake. Salads provide the body with a lot of fiber which in turn means lower cholesterol and less constipation. Furthermore, when you eat these green wonders, you feel fuller, eat less and lose weight.


Food provides the energy and nutrients you need to be healthy. Nutrients include proteins, carbohydrates, fats, vitamins, minerals, and water.

Healthy eating is not hard. The key is to

  • Eat a variety of foods, including vegetables, fruits, and whole-grain products
  • Eat lean meats, poultry, fish, beans, and low-fat dairy products
  • Drink lots of water
  • Limit salt, sugar, alcohol, saturated fat, and trans fat in your diet

Saturated fats are usually fats that come from animals. Look for trans fat on the labels of processed foods, margarines, and shortenings.

Human nutrition refers to the provision of essential nutrients necessary to support human life and health. Generally, people can survive up to 40 days without food, a period largely depending on the amount of water consumed, stored body fat, muscle mass and genetic factors.

Poor nutrition is a chronic problem often linked to poverty, poor nutrition understanding and practices, and deficient sanitation and food security. Lack of proper nutrition contributes to lower academic performance, lower test scores, and eventually less successful students and a less productive and competitive economy. Malnutrition and its consequences are immense contributors to deaths and disabilities worldwide. Promoting good nutrition helps children grow, promotes human development and advances economic growth and eradication of poverty.
