Understanding the Ayurvedic Concept of Food Properties
In Ayurveda, the healing science of India, foods are not classified as merely 'hot' or 'cold' based on their physical temperature. Instead, they are categorized by their virya, or potency, which is their effect on the body after digestion. Some foods have a heating virya (Ushna), while others have a cooling virya (Sheeta). This is an essential distinction to understand when asking, "is roti hot or cold for body?"
For example, while mint tea is physically warm, its virya is cooling. Conversely, ice cream is physically cold but has a heating virya. Therefore, to determine roti's effect, we must look at its ingredients, preparation, and freshness.
The Difference Between Fresh and Day-Old (Basi) Roti
The state of the roti is a major factor in its energetic properties, according to Ayurvedic principles. A fresh roti, hot off the tava (griddle), has a different effect than one that has cooled overnight. This is primarily due to changes in its molecular structure and digestibility.
The Warming Effect of Fresh Roti
Freshly cooked roti, particularly when made from whole wheat flour, is considered to have a slightly warming or neutral effect on the body. This is because the digestive process for the complex carbohydrates and proteins in wheat generates metabolic heat, a process known as thermogenesis. Whole grains require more energy to break down than refined flour, contributing to this warming effect. Ayurveda also suggests that freshly prepared foods are easier for the body's digestive fire (agni) to process, enhancing nutrient absorption and generating warmth.
The Cooling and Healing Benefits of Basi Roti
Day-old, or basi roti, is prized in Ayurvedic tradition for its distinct cooling properties and digestive benefits. As roti cools and is stored, the starch within it undergoes a transformation into resistant starch. This resistant starch is not easily digested in the small intestine, acting like dietary fiber that is fermented by beneficial bacteria in the large intestine. This process has several health advantages, making basi roti a powerful traditional remedy:
- Promotes Digestive Health: Resistant starch acts as a prebiotic, feeding good gut bacteria and improving the overall gut microbiome. This can help soothe acidity, bloating, and constipation.
- Controls Blood Sugar: It prevents a rapid spike in blood sugar by breaking down slowly, making it beneficial for managing blood sugar levels.
- Regulates Body Temperature: Consumed with a cooling liquid like cold milk, basi roti is believed to cool the body from within, making it ideal for summer.
Comparison: Fresh Roti vs. Basi Roti
| Feature | Fresh Roti | Basi Roti (Day-Old) |
|---|---|---|
| Effect on Body | Slightly warming or neutral due to active digestion. | Cooling due to conversion of starch into resistant starch. |
| Digestibility | Highly digestible due to freshness and warmth. | Easier to digest for those with sensitivity to fresh grains; acts as a prebiotic. |
| Glycemic Index | Slightly higher, as starches are quickly broken down into glucose. | Lower, as resistant starch breaks down slowly, preventing sugar spikes. |
| Best Season | Beneficial in colder seasons for its warming energy. | Ideal for summer to help cool the body and prevent heat-related issues. |
| Ideal Pairing | Best with warm daal or cooked vegetables for a balanced meal. | Traditionally eaten with cold milk or curd to enhance its cooling effect. |
The Role of Flour Type and Preparation
Beyond its freshness, the type of flour used to make the roti significantly influences its effect on the body. While whole wheat flour (atta) is the most common, other flours are used seasonally for their specific properties. For instance, millets like jowar are known for their naturally cooling properties and are a popular choice during the summer.
The preparation method is also key. Ayurveda suggests slow-cooking rotis on an iron or clay tava to aid digestion, rather than over a direct flame. Additionally, adding specific ingredients can alter the roti's properties. For example, adding jaggery (gud) and sesame seeds makes gud roti a warming food, excellent for winter.
Conclusion
The question of whether roti is hot or cold for the body has a complex answer rooted in Ayurvedic principles, which emphasize food's inherent virya rather than its physical temperature. A fresh, warm roti tends to be slightly warming or neutral due to the metabolic energy required for digestion. In contrast, a day-old basi roti is considered cooling and offers unique health benefits, particularly for digestion and blood sugar control, due to its resistant starch content. The type of flour and preparation method further influence this dynamic. Ultimately, the best choice depends on your body type, the season, and your health goals, highlighting the mindful approach to eating championed by Ayurveda. For individuals seeking to manage body temperature and improve digestive health, understanding the distinct properties of both fresh and day-old roti can be a powerful tool for maintaining balance.

How to choose between fresh and basi roti
- Choose Fresh Roti for Winter: Opt for warm, freshly cooked roti during colder months to take advantage of its slightly warming properties, which can help stoke your digestive fire and keep the body warm.
- Choose Basi Roti for Summer: When the weather is hot, a day-old basi roti, especially with cold milk or curd, can provide a cooling effect on the body and soothe the digestive system.
- Prioritize Basi Roti for Digestion: If you suffer from acidity, bloating, or constipation, the resistant starch in basi roti can significantly improve gut health and regularity.
- Use Basi Roti for Blood Sugar Control: For those with concerns about blood sugar, basi roti's lower glycemic index helps prevent spikes, making it a better option than fresh roti.
- Select Basi Roti for Weight Management: The fiber and resistant starch in basi roti promote satiety, helping you feel fuller for longer and aiding in weight management.
- Choose the Right Flour for the Season: In addition to roti's temperature, consider the flour type. Use naturally cooling millets like jowar or bajra in summer and warming whole wheat or multigrain blends in winter.
