World Health Day And Eating Local: How

Seasonal Eating

Impacts Physical Well-Being

How Seasonal Produce Matches the Body's Physical Needs

India's geographic diversity gives it a particularly rich collection of seasonal produce. There’s the leafy greens, root vegetables, seeds, stems and more, which change with seasons. Local culinary practices, especially in India, also focus on eating the roots to the tips of the most edible plants. Here are further reasons to go for seasonal ingredients: 

• Immunity: Eating seasonal fruits and vegetables helps boost immunity as they are packed with essential vitamins, minerals, and antioxidants required by the body. Winter seasonal foods like carrots, cauliflower, and oranges, which are high in Vitamin C, can help fight off infections and prevent cold and flu.

• Digestion: Eating seasonal foods can help improve digestion, decrease bloating, and promote gut health. The summer season brings refreshing fruits such as watermelon, muskmelon, and mangoes, which aid digestion and also help rehydrate the body.

• Detoxification: Seasonal foods support the liver, kidneys, and lymphatic system, helping the body naturally eliminate accumulated toxins. Bitter greens in spring, juicy fruits in summer, and root vegetables in winter serve as gentle, effective detox agents.

• Metabolic health: The digestive fire fluctuates with the seasons. Eating seasonally ensures that food is easier to digest, reducing bloating, gas, acid reflux, and constipation, while also helping regulate metabolism and maintain a healthy weight.

Research also suggests that even the activity of our genes tends to change with the seasons, which corresponds to broad shifts in the type and quantity of immune cells the body produces. This makes the case for seasonal eating biological, not merely cultural.

The Role of Millets

No discussion of Indian seasonal eating is complete without millets, which are an ancient superfood. Millets are abundant sources of minerals and vitamins, and contain valuable phytochemicals that impart therapeutic properties for various disorders and diseases, giving them nutraceutical value. 

India is the world's largest producer, contributing approximately 41% of global output. The major millets, bajra, jowar, and ragi, are relatively well known. However, the minor millets are where the nutritional density often gets higher. Take a look: 

• Kodo Millet (Varagu or Arikalu): Kodo millet was domesticated in India around 3,000 years ago and has a decent amount of protein and fibre. It also supports strengthening the nervous system and is rich in antioxidants.

• Browntop Millet (Korale): One of the rarest millets commercially, it is part of the Siridhanya group – five ancient unpolished grains. It is known for its high amount of micronutrients.

• Little Millet (Kutki or Saame): Little millet is a traditional crop that has been growing in India since 2700 BC, particularly suitable for areas with low rainfall. It is packed with calcium, iron, potassium, zinc, and phosphorus, and is particularly useful in weight management diets.

• Proso Millet (Chena): Proso millet is a lesser-known variety but a powerhouse of nutrition. It is rich in protein that supports muscle health, boosts metabolism, and helps reduce cholesterol levels, and is packed with niacin (Vitamin B3), fatty acids, and essential minerals like magnesium and phosphorus.

• Barnyard Millet (Sanwa or Moraiyo): Low in calories and high in iron and fibre, this millet is widely used during fasting periods and is an important iron source for vegetarians.

• Foxtail Millet (Kangni): Foxtail millet is a rich source of Vitamin B12 and helps in regulating nervous system functions. It is a powerhouse of nutrition that helps in building stamina and boosting immunity.

World Health Day is also a reminder that nutritional deficiencies, particularly anaemia in India, remain a major public health concern. Pearl millet contains approximately 8 milligrams of iron per 100 grams, significantly higher than wheat (3.5 mg) and rice (0.7 mg), making it one of the most powerful dietary tools against iron-deficiency anaemia, which affects an estimated 50% of women of reproductive age in India.

Seasonal Produce Chart Across India’s Five Seasons

The chart below covers produce available broadly across Indian regions. Lesser-known items are marked with ‘*’ for emphasis.

* = Lesser-known or underutilised; prioritise these for nutritional diversity in your seasonal eating chart.

Notable lesser-known produce with strong health relevance:

• Bathua (Chenopodium album): A winter green that is eaten as a saag, it’s rich in calcium, iron, and vitamin A, and traditionally used in North Indian cooking.

• Elephant Yam (Suran): A monsoon and winter tuber with prebiotic properties that support gut health. For a plant source, it is also high in omega-3 fatty acids.

• Moringa leaves (drumstick leaves): Available in monsoon and spring across South and Central India, these are among the most nutrient-dense leafy greens, containing more calcium than milk per serving.

• Amla (Indian gooseberry): An autumn-winter fruit central to Ayurvedic formulations like Chyawanprash, it is one of the richest natural sources of Vitamin C. 

• Colocasia leaf (Arbi patta): A monsoon vegetable, colocasia leaves, including the root vegetable arbi, are full of soluble dietary fibre, calcium, potassium, and vitamins C and B9. It’s commonly eaten in Maharashtra, Gujarat, Himachal Pradesh, West Bengal, and Bihar.

• Bael (Wood apple): This one is a fibrous summer fruit with exceptional gut-healing properties, especially for IBS and dysentery. It is drunk as a sherbet.

Eat Seasonally This World Health Day

Eating seasonally isn’t complicated; you just need to be smart about it and pick up local produce. In-season anything, fresh off the farm, tastes better, costs less, and retains more nutrients than out-of-season stuff. So, instead of chasing trends or imported produce, focus on what’s naturally available around you, this World Health Day.
