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.

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. 
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. 
There is a large variation between states in risk factors associated with health between the states. 
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.
- Smoking – Women: Tamil Nadu (0.0%) to Mizoram (18%)
- Smoking – Men: Maharashtra (16%) to Mizoram (67%)
- Obestiy (BMI >= 25): Madhya Pradesh (8%) to Kerala (27%)
- Hypertension: Andhra Pradesh (17%) to Madhya Pradesh (21%)
- Diabetes – Women: Mizoram (0.5%) to Kerala (5.3%)
- Diabetes – Men: Madhya Pradesh (0.6%) to Kerala (6.5%)
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. 
Yellow shows the lowest third, blue the middle third and green the highest third.
