Introduction
School children are the future generation of tomorrow, according to UNICEF, age group of 6 to 12 years are considered as the Schoolage children [1]. They have a consistent but slow rate of growth and usually eat four to five times a day including snacks. Maintaining their health, growth and development is very important during this age group. These age group children face rapid development-mentally and physically, thus good nutrition is very important at this phase of life. The eating habits in children developed at birth are generally continued into adulthood. The food choices influence the eating habits. Many food habits, likes, and dislikes are established during this time. Family, friends, and the media especially TV influence their food choices and eating habits [2].
Nutrition is the process of taking of adequate amount of nutrients from the foods we eat. Also, it is the building blocks of life as it uses food for growth, repair and maintaining of the body. The essential nutrients for life include carbohydrates, proteins, lipids, fiber, vitamins, minerals and water-the solvent of all ingredients in the blood and cells [3].
According to the reports there are number of factors that influence the dietary choices, pattern and practices of individuals such as food accessibility, food characteristics, environmental and psychological influences [2].
Similarly, changes in the dietary pattern towards frequent snacking, eating dense foods and sweetened beverages that is away from home food leads to consumption, of high energy low nutrients that have implicated to childhood obesity. This childhood obesity also track into adulthood and increase the risk for later development of chronic diseases such as coronary heart disease, high blood pressure, diabetes, hyperlipidemia and various type of cancer. The food selection and consumption also affect the general health status [4].
Good nutrition means getting the right amount of nutrients from healthy food in the right combinations. Proper nutrition helps in developing and maintaining good health, cause being healthy not only makes us feel great, but also enable us to enjoy life to our fullest potential and follow our dreams [5].
According to WHO “health is a state of complete physical, mental, social and spiritual wellbeing and not merely the absence of diseases or infirmity [6]. Several government agencies have published recommendation for an adequate diet, which focuses on obtaining ample calories, vitamins and minerals to support growth and a healthy life through everyday consumption of healthy foods [7].
The Dietary Guidelines for Americans encourage the consumption of fruits and vegetables that focus on health promotion and disease risk reduction. Meeting the daily fruits and vegetables recommendations is beneficial in preventing chronic diseases, because they are nutrientdense, high in fibres and low in energy density. Consuming the suggested amount of fruits and vegetables will provide an assortment of micronutrients and fibres, which promote good health and assist in preventing chronic diseases [8].
There is compelling scientific evidence that a diet rich in fruits and vegetables is associated with multiple health benefits. A substantial amount of scientific evidence shows that high fruit and vegetable intake can reduce the risk of e.g. cancer, cardiovascular diseases, diabetes, cavity and may protect against a range of childhood illnesses such as respiratory symptoms [7].
Dietary Guidelines and the Food Guide Pyramid recommend eating five or more servings of fruits and vegetables per day (US Department of Agriculture, 2010). According to the Ministry of Health Malaysia the recommended intake of fruits and vegetables is five servings (approximately 400 g) which are two servings for fruits and three servings for vegetables per day, 2010). The health benefits of fruits and vegetables seen in epidemiological studies are the main reasons for the recommended intake of at least 400 g of fruit and vegetables per day [9].
Having nutritional knowledge and making smart choices about the foods we eat can help the children to achieve optimum health over lifetime, and be a key to avoid obesity, illness and most prevalent chronic disease. And thus, health promotion from the early stage in life by fostering healthy eating practices and regular physical activity has the potential for a major impact on health and wellbeing during childhood and in the later stages of life as well [10].
“Eat the Rainbow” is a teaching programme designed for the children in order to, encouraging the children to include fruits and vegetables in their everyday diet, So that to obtain all the nutrients needed for their bodies.
Hence based on the above statistics and findings, the study on the “effectiveness of Eat the rainbow nutrition education intervention” on knowledge and practice regarding inclusion of fruits and vegetables in the diet among school children in selected school was undertaken to improve the knowledge and practice among the children . The main aim of the study is to assess the knowledge and practice regarding inclusion of fruits and vegetables in the diet among school children before and after eat the rainbow nutrition education intervention among school children.
Materials and Methods
A pre-experiment design with one group pre-test post-test design to assess the effectiveness of the eat the rainbow nutrition education intervention on knowledge and practice regarding inclusion of fruits and vegetables in the diet among school children was carried at Primary School, Bengaluru.
After extrinsic review and obtaining Opinions from the experts the tools for data collection were developed .The investigator ensured that pretesting, reliability and content validity were obtained prior to the data collection. The constructed tools consist three sections:
• Socio-demographic variables which had 10 items- age, gender, religion, educational status, educational status of mother, educational status of father, occupational status of mother, occupational status of father, family income and dietary pattern.
• Structured knowledge questionnaire regarding inclusion of fruits and vegetables in the diet among school children consisted of 10 items. Every “right” answer was awarded a score of “1” and every wrong answer was awarded a score of “0”. Thus a total of 10 marks were given for knowledge questionnaire.
To interpret the level of knowledge, the scores were distributed as follows:
• Maximum score =10
• Inadequate knowledge: <50% (>5)
• Moderate knowledge: 50-75% (5-7)
• Adequate knowledge: >75% (>7)
• Structured food dairy is a chart used to track inclusion of fruits and vegetables in the diet over the week. The structured food dairy consisted of 5 tables that are from Monday to Friday that include breakfast, morning snack, lunch, afternoon snack, dinner and bedtime snack.
The list of all the fruits and vegetables consumed by the school children were grouped into 5 different colours (red, yellow/orange, green, blue/purple and white). And total of daily frequency of consumption of fruits and vegetables were calculated from the structured food dairy by summarizing the consumption per day for each item and was scored as follows:
Interpretation of score
The total score of fruits and vegetables was calculated by adding all the fruits and vegetables consumes by the school children in all 5 days of the week. A total of 10 score was awarded for vegetables and fruits respectively, the scores were distributed as follows Table 1:
| Fruits | Vegetables | |||||
|---|---|---|---|---|---|---|
| Consumption | 2 | 1 | NO | 4-5 | 3-2 | 1/ NO |
| Score | 2 | 1 | 0 | 2 | 1 | 0 |
Table 1: A total of 10 score was awarded for vegetables and fruits.
Maximum score was 10 for fruits and 10 for vegetables.
• <5 (< 50%) =Inadequate practice.
• 5-7 (50-75%) =Moderate practice.
• >7 (>75%) =Adequate practice.

However, with regards to education of the father and occupation of mother had significant association.
Discussion
Eat the rainbow nutrition education intervention is an important programme to be included in the schools which play a significant role in promoting the healthy life style among school children. According to the school health, guidelines healthy eating and regular physical activity play a substantial role in preventing chronic diseases. Multiple factors including demographic, personal and environmental factors influence the eating behaviour of children [11]. Therefore, it is necessary to educate the children and impart them with healthy eating habits during the early school age.
In this study eat the rainbow nutrition education intervention was effective in enhancing the knowledge regarding the inclusion of fruits and vegetable in the diet as well as changes in the intake of fruits and vegetable. This study also found significant difference in the knowledge and inclusion of fruits and vegetables in the diet. Similarly, a study conducted in elementary school to test difference on mean fruit and vegetable eaten, liking, preference and selfefficacy scores denoted that there was a significant difference in the intervention group as well as between the pre and post- test intervention [12].
The study result shows that the nutrition education intervention with colour fruits and vegetables is an effective method of teaching in improving the intake of fruits and vegetable in the diet.
Conclusion
This study concludes that a well-planned teaching program improves the knowledge among school children and including various methods of teaching and activities enhances the knowledge and attract the school children’s to learn. Implementing similar program at various settings and among different age group children can improve the eating habits among the children.
