India is divided into 29 states and 9 union territories. In 2014, Telangana was separated from Andhra Pradesh. As a result, the statistics included in this document  for Andhra Pradesh also includes Telangana.[1]

Despite the reputation for vegetarian cuisine, it is not justified. Only 1.5% of Indians are vegan, 24% are lacto-vegetarian. 3% add eggs to their lacto-vegetarian diet which leaves 72% consuming meat.

Religion has a strong influence on diet with Muslims being restricted in eating pork and Hindus from eating beef. Jain and some Hindus have a strong preference for not eating meat.

There is much variation in diets in different regions of India with the uses of dairy, meat, fish, oils, vegetables, the use of spices and cooking methods.

Religion

The highest levels of Buddhist population are found in the northeast with Sikkim (27%), Arunachal Pradesh (12%), Mizoram (9%) and Maharashtra (6%).

Muslims are found more in the north with Lakshadweep (97%) and Jammu & Kashmir (68%) in the far northwest having the highest populations. Assam in the northeast has 34% and West Bengal 27%.

Christian households consume much more rice than ‘other religious groups such as Jains, Buddhists and Sikhs who consume a much larger portion of wheat.

The lighter the regions, the higher the incidence of the adherents. Data is from 2011 Indian  Census. [2]

Indian Regional Diets

From the 1990s,  there has been a fall in cereal intake with maize, barley, sorghum and millet being particularly affected. Consumption of vegetables, fruits and milk products has not increased significantly in the diet of rural population.

Regions with higher intake of cereals and milk consume the highest amount of nutrients.

Coarse cereals consist of maize, barley, sorghum, millet and other minor grains.

Pulses, beans and lentils are the central to Indian food. Pulse refers to dried seed. Daal refers to the split version of pulses such as lentils, peas, chickpeas and kidney beans.

Green gram is the same as mung beans. Black gram is known in India as urad which is similar to the mung bean.

Tomatoes via Portuguese explorers in the early 16th whilst potatoes were introduced in the early 17th centuries.

The following table shows the percentage difference in food intake when compared to the national average. All food is assigned to one of the categories.

If the difference is between 90-110%, then it is omitted.

There are many species of millets grown in the west and south of India with the states Karnataka, Maharashtra, Tamil Nadu, Madhya Pradesh, Rajasthan and Gujart being the major areas. Although millets have always been secondary to rice, wheat and barley, it has been important in these areas. Millets are able to be grown on land that is not suitable for other cereals.

Millets are good sources of thiamine (B1), riboflavin (B2), pyridoxine (B6) compared to wheat and rice. Millets also have high amounts of have good amounts of folic acid, iron, zinc, calcium, magnesium, sodium, potassium compared to rice and wheat. They are also high in fibre. [5]

During the years 1987-1988 and 1999-2000, the consumption of cereals decreased with millets decreasing significantly. Dairy, added oils, meat and processed food rose with meat, fish, eggs and processed food being particularly significant. These changes were not evenly spread throughout India. Meat, fish and egg consumption rose more than 100% from an already high level in West Bengal. [6]

Contribution of millets in total food grain production of India reduced from 22.17 % to 6.94 % over the last six decades from 1950-51 to 2011-12. [7]

The consumption of cereals barley, maize and millets in rural areas was reduced 50% from 2.59 to 1.30 kg/per capita/30 days during the period from 1987-88 to 1999-2000. In Andhra Pradesh, the consumption was reduced by 75% from 2.3 kg/per capita/30 days.[8]

Indian Diet and Health

The Indian population has the highest prevalence of diabetes worldwide and exhibits high-risk metabolic profiles at younger ages and lower body mass index than their Western counterparts. There are significant regional variations to this observation. [9]

The reasons why Asian populations exhibit diabetes at a lower threshold than western populations are not known.

According to WHO figures, India is ranked 17 for Low Birth Rate, 37 for Diarrhoeal Diseases, 40 for Tuberculosis, 60 for Malnutrition and 62 for Influenza & Pneumonia out of 183 countries. [10]

There is a large variation between states in risk factors associated with health between the states. [11]

In the data below, diabetes was defined as a fasting plasma glucose level >= 7.0 mmol/L or >= 11.1 mmol/L for non-fasting. Hypertension is as systolic blood pressure of at least 140 mmHg or diastolic blood pressure of at least 90 mmHg. The threshold for these definitions are high with optimal fasting glucose being 5.5-6.0 mmol/L and systolic blood pressure being less than 120 mmHg.

Age-standardized diabetes prevalence for men rose from 3.7% to 9.1% for women from 4.6% to 8.3% between the years 1980 to 2014.[12]

There is a large variation in life expectancy between rural and urban populations and state populations. (Data from 1998-2002) The lowest life expectancy in rural India is Madhya Pradesh at 55.6 years with Kerala having the highest at 73.4. The difference between rural and urban populations is greatest in Assam at 9.5 years. [13]

Yellow shows the lowest third, blue the middle third and green the highest third.
