Centers of yog and ayurved have been focusing on the diets in India. Because, diet is the very basis of ayurved which is a positive science of age and health. At the same time, allopathy is the science of various types of diseases. Greek meaning of allopathy is “allos” which is made of opposite and pathos. As the people suffering from constipation is advised to consume lecmetive which makes an adverse impact on the patients. It means that allopathy is a militant treatment, while ayurved, yog and nisarg treatment are the positive science of health of body, mind and consciousness. They check the diseases instead of suppressing them. That’s why, it has been said that –‘svasthasyasvasthyarakshanamaaturasyavikaraprashamanam cha iti yog nisargopacharaayurvedasyamulaprayojanam I’ It means that while boosting health of people, checking and balancing disorders like rheumatism, bile and cough ‘doshameva hi sarveshamroganamekakaranam’ (Bagbhatta) are the main features of ayurved, yog and naturopathy.
‘Yadyapathayamkimaushadhyahyadipathyamkimaushadhaih’ is mantra of ayurved in getting rid of disorder and conservation of health. It means that if you consume proper diets, you will get rid of diseases. It’s the great sutra of health.

The diet is of great importance in ayurved. Many mantras describe diets as the best and the great medicines-

‘Na cha aaharasamamkinchitabheshajyammupalabhyate’

There is no medicine is greater than that of diet. That’s why, it has been said that –

‘binapibheshajaivyadhipathyadevnivarttate I Na tupathyavihinasyabheshajanamshatairapi’ I

No medicine is effective without proper and balanced diet. Lord Shrikrishna has made it clear in the Gita that ‘yuktaharviharasyayuktacheshtasyakarmasu' I Yuktasvapnaabodhasyayogobhavatidukhaha I’ It means that those people who consume balanced diet and indulge in proper lifestyle and sleeping get rid of diseases. They lead their life properly. Our Upnishad, Ved, Upved, Vedant, Brahman and Aaranyak, etc have described diets in detail. Chhandogyopanishad cites this mantra ‘aaharshuddhausatvasuddhisatva Dhruva smriti labdhesarvagranthinamvipramokshah II It means that pure diets make our existential life aesthetic. Our internal consciousness becomes pure. It eradicates jealousness, hypocrite, etc. The peaceful mind eradicates all the mental complexes and brings divine purity and serenity. The diet has been described elaborately in Chhandogyopanishad 6.5.1 to 6.5.3. 

Annashitamtredavidhiyatetasya yah sthavishtodhatustatpurishambhavati I Yomadhyamastanmansamyoaniptastanmanah II

It means that consumed food items turn into three types. Lowest part becomes stool, middle part turns into flesh and micro part turns into mind. 
Tejoashitamshredhavidhiyatetasya yah sthavistodhatustadasthibhavatiyomadhyamahsamajjayoanishthahsavakII It means that major part of consumed ghee turns into bone. The middle part becomes bone marrow and the micro part turns into speech. Vak Maharshi Ambhurin’s daughter and Kashyap Rishi’ wife has written SuktamRingvedoktama (8 shloka of Ringved, 10 mandal, 10 anuvak, 125 suktam). Language, speech, sound and oratory are the deities of phonetics. ‘Aapah pita stredhavidhiyantetasam yah sthavishthodhatustanmutrambhavatiyomadhyamastallohitayoanishkahsapranah I’ It means that lower, middle and micro part of consumed water turn into urine, blood and vital energy respectively. That’s why, mind, food grain, vital energy and speech become aesthetic. 
Aayuraighritamityadivat means ghee is the age because it boosts life. It’s ‘Kathopnishad’. Consuming ghee after doing hard work boosts age. Those people who do no hard work and consume ghee fall prey to cardiac arrest. 
Ayurved mentions innumerable mantras to get rid of diseases through diets. Mitbhojanamswasthyam, yenaaaharaviharenaroganamudbhavabhavet, jirnebhojanammatreyahlaghanamparamaushadham. It means that the people should eat food after digestion of previous food. Do fasting to get rid of indigestion. Jirnehitammitam cha aadyatajirnebhojanamvisham, dukhamtathaiva cha papamatibhojanamrogamulam, mitambhojanamswasthyamatyashanamvaadhyashanam dukkha cha rogamulam, atyashanam, adhyashanam, samashanam, ahitaashanam cha santyajyama I
According to an interesting story, once upon a time, Charak uttered like pigeon koaruk-koaruk in the various ashrams to test his disciples who failed in it. Only Bagbhatta replied to it- hitabhukmitabhukritubhuk it means that those people who consume proper diet as per season, atmosphere and nature get rid of various types of diseases. 
Lord Shrikrishna himself has analyzed diets in the Gita-

Aayusatvabalaaarogyasukhapritivivardhana I Rasya, snigdhasthirahridyaaaharasatvik Priya II

The people should consume those diets which boost age, aesthetic, immunity, prosperity, brotherhood, affection, peace, etc. They should consume vegetables, germinated food grains, fresh fruits, milk, curd, chhachh, etc. Therefore, the diets must boost age, encouragement, existential strength, health, peace and prosperity. Such people do good deed. They renounce longing, jealousness, greed, etc. They are non-violent, affectionate, peaceful, etc. Their body is pure. 
Diets of aesthetic people make great impact in the world. They start witnessing the god in every animal. They are non-egoist. Aesthetic deed provides good result. Those people who are egoist, violent and unwise prefer non-vegetarian food items. Lord Shrikrishna has described it as such-

Katu amla lavanaatiushnatikshnarukshavidahinah I Aahararajasasyaishtahdukhshokaamayapradah II

Those people who are of rajasic nature prefer sharp, bitter, salted, hot, dry food items which provide nothing but grief, diseases, etc. Such people are egoist. They want to become famous in name of hypocrisy by performing yagya. 
Rajasic food items make people lazy, egoist, impure, etc. They want to attain anything without doing hard work. They know nothing about religion, religious duty and meaning of reality. They continue to indulge in anarchy. They consider materialistic life as the religion. Their life is full of impurity, mean character, jealousness, etc. They are unwise, ignorant, sinner, cruel, etc. They consume that food items which boost sex, anger, greed, jealousness and violence. Lord Shrikrishna himself has described it- 
Yatayam gat rasamputiparyushitam cha yat I Udhishtamapi cha bhojanam tamas priyas I
It means half-cooked, stale and impure food items are impure. Tamasic people prefer such food items. Such people are full of longing, violence, jealousness, etc. They are ignorant, lazy, cleaver, irreligious, fearful, cruel, promiscuous, etc. It’s the repercussion of such food items. 
According to analysis of aforesaid food items, arrangement of non-violent, aesthetic and life providing medically certified diets have been made at Patanjali Yogpeeth-run Yogagram and Patanjali wellness centers. Such diets are provided to the patients admitted in these centers. These diets are providing physical, mental, moral and spiritual health for the patients who get rid of many chronic diseases. The credit goes to around 1500 scientists and thousands of other competent health workers under sheer guidance of Patanjali Yogpeeth patron, guide and yog scientist Swami Ramdev Jee Maharaj and ayurved great scholar Acharya Balkrishna Jee Maharaj.
That’s why, Patanjali Yogpeeth is providing a new lease of life in the field of health, education, ayurved, naturopathy, yagya, acupressure, etc. Patanjali Yogpeeth is building new world by creating new humanity not only in India but also in the abroad. New humanity is free from jealousness and diseases.
