Aubrey had paradoxical findings that 800 million people in the world face acute starvation, are malnourished, while 1.9 billion people have excess weights, and are at risk of health complications (2019). This figure includes 41 million overweight children. The survey assessed people's diets in 95 nations using household data (Aubrey, 2019). The data was analyzed to assess the impacts of a poor diet on health. The results were analyzed against global deaths associated with tobacco. Nations that had the least cases of diet-related deaths were France, Israel, and Japan (Aubrey, 2019). The World Health Organization holds that a healthy diet and lifestyle significantly reduce the risks of non-communicable diseases (NCDs) such as cancer and cardiovascular complications (2020). The opposite of the same is true, which increases the global risks to health and wellness. A healthy lifestyle and diet should start early in life through breastfeeding and indulging children in physical activities to promote social, cognitive, and physical fitness in the long term (Medical Research Council,2017). The daily intake of calories should reflect the body's energy demands to prevent the risks of malnutrition and unnecessary weight gains (Popkin et al., 2013). The total body fat should be at most 30% of the energy intake, and the consumption of saturated fats should not exceed 10% of the total energy intake. The trans-fats intake should be less than 1% of the energy intake (Popkin et al., 2013). People who lack the necessary micronutrients and vitamins worldwide are about 2 billion (Beaudreault, 2020). The children with low heights compared to their ages are 150.8 million, which translates to one in every four children. Out of this population, 71% live in Southeast Asia and Africa (Beaudreault, 2020). It is further estimated that 9.7% of women between the ages of 20 and 49, and 5.7% of adolescent girls are underweight, and 15.1% are overweight (Beaudreault, 2020). This increases the risk of anaemia for pregnant women by 40.1%. In every three people in the world, one is either obese or underweight. Nutrition is fundamental in ensuring people reach their full potentials (HHS, 2017). Poor nutrition contributes to a high mortality rate and a high cost of care by increasing non-communicable disease risks. Proper nutrition and healthy lifestyles can help reach and maintain healthy weights, reduce the risks of chronic disease, and promote people's overall wellbeing. Diet and lifestyle are directly associated with non-communicable diseases. Main body : Human health goes beyond the physical fitness or disease absence. Healthy people are efficient at work and in society (Rathnayake et al., 2020). They have longer lifespans and less demand for healthcare services. Good health is defined by eating habits, regular physical activities, and personal hygiene. The basic nutrition has a proper balance of proteins, fats, and carbohydrates and forms the basis of all life activities. The diet makes up functional body molecules, the carbon skeleton, and the energy for driving the body processes (Rajendra et al., 2015, p. 3). Its primary function is to power the body, prevent nutritional deficiencies, and prevent NCDs (Rajendra et al., 2015). It has to be kept at the right balance because too many nutrients in the body result in overweight, while inadequate amounts lead to malnutrition. Fanzo considers diet as the leading factor of most non-communicable morbidity and mortality (2016). Excessive nutrition makes the bodies absorb and store excess energy and fats that are detrimental to health. The intake of healthy diets with high concentration of nutrients are paramount in minimizing the risks of most communicable diseases primarily in the older adults since they are at the highest risks of these diseases (Bruins et al., 2019).
