Introduction
Health is a positive concept accentuating social and personal assets as well as physical and psychological aptitudes. In the healthy condition an individual can satisfy needs and can deal with interpersonal, social, biological and physical environments. therefore, it is a resource for every day (McCartney et al., 2019). In the perspective to understand health, it is required to focus on the concept of global health. It is an area for study, investigation and practice that places precedence on refining health and attaining justice of health for all people internationally. Global health emphasizes worldwide health issues, causes, and solutions; includes numerous corrections within and beyond the health sciences and indorses interdisciplinary association (Koplan et al., 2009). In addition to health, quality of life involves the standard of living, the quality of housing and the neighbourhood in which one lives, job satisfaction, and many other factors. According to World Health Organisation (WHO) health is defined as a “state of complete mental, physical, and social well-being and not only the absenteeism of disease or disability. Health brings “broadness”- nothing is missing from the person; it brings “proper functions”-everything is working proficiently (John, 1987).
Diet
According to modern science the gross (physical) body is made up of packets of energy. The ancient scripture taitiraya upaniñad has mentioned that physical body is made of annam and the annam is called food; which consist of païcamahäbhüta (påthvé, jala, äkäça, väyu and agni) (Kuldeep et al., 1981). The yogic diet mentioned in kaöhaupaniñad and haöha yoga scriptures is consist of cow milk, cow ghee, sprouts, fruits; which is easy to digest and helps to maintain the physical and mental health. The bhagavadgétä highlights three categories of food tämasika, räjasika, and sätvika based on the characteristics of food and its influence on the human personality. The quantity of food, place, time, mental state also contributes equally to maintain the positive health (Kwon & Tamang, 2015).1, 2 The haöha yoga explained äyuùsattvabalärogyasukhaprétivivardhanäù rasyäù snigdhäù sthirä hådyä ähäräù sättvikapriyäù || 17-8||. The food which endorse cheerfulness, joy, health, strength, energy and life, which are sweet and juicy (milk, fruit) which provide strength to heart the person who like such food is of sättvika nature.

Diet and spiritual well-being
Spiritual well-being is referred as one of the major concepts in patients dealing with stresses and problems produced by the disease, it shows a crucial role in arousing the sense of identity, inner balance, satisfaction, beauty, love, respect, happiness, positive attitude, perfection and purpose in life (Musavi et al., 2020). There is a huge impact of diet on spiritual well-being. Spiritual well-being is an important aspect in the perspective of the adherence to diet in dialysis patients (Musavi et al., 2020).3 Nowadays many healing centers are growing emphasizing vegetarianism and veganism for good health and spiritual purification. Our spiritual transformation deepens with the sätvika diet (Will, 2016). In the case of a non-veg diet; spiritual concerns and health have superficially motivated refraining from meat (Kristensen et al., 2015).4 Food and well-being are interconnected to each other. For defining well-being; six interconnected dimensions are there:-social, spiritual, emotional, physical, occupational and intellectual (Ares et al., 2014). Food has been described to be one of the specific phases of life that affects individual well-being (Ares et al., 2016).5, 6

Higher intake of fruits and vegetables with healthy fat always leads to a better quality of life (Hadgkiss et al., 2015).7 Nutritional status and diet are thought to be very effective for reducing the risk of prostate cancer-specific mortality, and managing other clinical endpoints such as quality of life (Baguley et al., 2017).There is an important role for nutrition therapy in relation to improving quality of life for HIV-positive people (Reid & Courtney, 2007).8 It is shown in a study that after receiving guidance on diet management, quality of life increased and symptoms of irritable bowel syndrome decreased (Østgaard et al., 2012).

Diet and Lifestyle modification can be effective in controlling non-insulin-dependent diabetes mellitus (NIDDM) and reducing risk factors linked with macrovascular complications (James & Tiffany, 1994).9, 10, 11 The other type of diet known as Pistachio diet also improved endothelial function, blood glucose level, some indices of inflammation, and oxidative status in healthy young men. Studies have also shown that frequent nut consumption decreases the risk of coronary artery disease (Sari et al., 2010).12, 13 A low-carbohydrate ketogenic diet (LCKD) have also shown beneficial effects in patients with type 2 diabetes; including reduction in anti-diabetic medication dosage (Hussain et al., 2012).

Dietary factors play a major role in the growth of iron deficiency (Vibha, 2015).14 Diet of normal calorie consisted of moderate carbohydrate, high protein and rich in vitamins with high amount of vegetables and fruits can increase the hemoglobin level (Bajpai et al., 2016).15
Diet and anthropometric variables

Vegetarian diet shows lesser BP values in hypertensive subjects (Jenner et al., 1988). The diet approach to stop hypertension is recommended to lower the blood pressure. Diet improves cardiovascular risk factors and beneficial in increased cardiometabolic risk (Siervo et al., 2015).17 Dietary approach to stop hypertension shows a high reduction in blood pressure and greater improvement in autonomic and vascular functions (Blumenthal et al., 2010).
