According to a Swedish study published in the journal of the American college of cardiology four out of five heart attacks can be prevented by following 5 healthy behaviors, maintain healthy weight and diet (avoiding junk and packed foods), exercising, not smoking and moderating alcohol use. But they don’t remember that they are eating slow poison to put themselves into risk and this junk food habit is 89.9% prominent among college youths according to many studies done by nutritionists3, 4.

National survey suggested that the physical activity and fitness level is declining due to this junk food habits in 1950.  The importance of fat was studied by Prof. Ancel Keys in the seven nations study, where keys and co-workers found that Finland and UK had high coronary heart disease (CHD) compared to this the problem is in low level in Japan and Greece (Crete).

In 2000, the sub-committee on nutrition of the United Nation (UN) produced another major statement with the 4th report on the by world nutrition situation. Nutrition throughout the life-cycle, these reports proposed that trends in global diet-first noted in affluent societies but emerging in developing societies-are followed by the emergence of clear patterns of chronic disease, particularly Cardio Vascular Disease (Coronary Heart Disease, High Blood Pressure, and cerebro-vascular Disease), some Cancers(Stomach, Colorectal, Breast, Prostrate and so on), Diabetes, Obesity 5, 6, 7.

According to WHO in 2005 there were about 1.6 billion overweight person aged 15 years and above and among them at least 400 million adults were obese. As a resultant of this food culture there is an increased level higher prevalence of 1.7 billion people classified as overweight 8, 9.

Study Instruments: Validated questionnaire used for obtaining statistically useful personal information from the individuals.


Demographic analysis of junk food habit respondent from age 17-35 years were chosen in that 23-years old were higher in ratio following that 22-years,21-years and 20-years, the junk culture among college student is more among the age 23years and the value is calculated giving 100% for 70 samples.

But the real fact is obesity, thyroid and anemia playing its role in this food habit. This is the main problem caused more among the youths and this is actually an initial problem but which gets complicated due to the junk food habits which the youths follow is highly dangerous.

Table 8: Polycystic Ovary Syndrome due to junk food eating habit


Mr.Ardith R, Mr.Brunt and Mr.Yeong S. Rhee (2008) studied on “Obesity and Lifestyle in U.S. College students related to living arrangements”, Where the objectives on the influence of dietary variety and other behaviors among American College students. The samples were primarily white of traditional college age, and primarily female, and the sample size were 738 surveys and participants returned were 585 (79%) 10.

The junk food culture and the bad lifestyle is more prominent among the off-campus students that is who stays away from family, this result is accepted but even though the youth who is staying with family is also prone to this junk food culture and spoiling their health in additional to this argument there is another review placed by Dr. Melody Y. Knight, Dr.Lorraine Killion, Dr.Larry P. Knight (1st Jan 2014), studied on the “Nutrition, Exercise habits, and perception of Obesity in Hispanic College Students in South Texas: A 10 years follow up”, Where the objective was to determine whether Hispanic College Students perceive themselves to be more Overweight than other ethnicity and to find out the diet practice, lack of exercise and also both categories 11.

Mr. Goel S, Mr. Karur T and Mr.Gupta M (March 2013) researched on “Increasing Proclivity for Junk Food among Overweight Adolescent Girls in District Kurukshetra, India”, the study progressed in such a way that in obesity in adolescents in gradually becoming a major public health problem in many developing countries, including India. Being overweight as an adolescent is associated with being overweight as an adult, the objective was change in dietary habit of consuming more high energy junk food and shifting to sedentary lifestyle is likely to be one of the important precursors of overweight and obesity among adolescent 12.

Research study on the college students food habits connecting with case study was done by Ms. S. Steffi and Ms. R Mary Josephine (Jan-Mar 2013),”A Case Study on Trend of Food Style among College Students”, this study was undertaken to explore the trend of having food related lifestyle among the college students, objective was to identify the Socio-Demographic characteristics and investigate the difference in attitude towards fast food, junk food and normal food 13.


Obesity is now accepted and acknowledged as a problem amongst youth and by youth. However, attitudes towards prevention of obesity through employment of healthier habits remain mixed, with primarily negative connotations around healthy lifestyle choices. It is well documented that excessive caloric intake and inadequate physical activity are important contributors to weight gain and obesity. Study suggests that youth may benefit from education designed to increase the desirability of healthy habits, either from gaining benefit or from avoiding consequences, specifically linking lifestyle choices with weight-related outcomes.

Limitation of the study: Lack of time to analyze complexity of disease was the main problem. More sample size would have been done for broader outcome of this survey.

Recommendation: More research can be done on the eating habit and complication caused by the eating habit to youth, the infertility problem occurring due to junk food culture can be researched and the major complexity in brain signaling and body metabolism can be researched.
