In Hindu culture, fasting or "Vrat" is often observed on specific days or during religious festivals. During these fasting periods, individuals abstain from consuming certain foods like grains, non-vegetarian items, and some vegetables. Here's a list of vegetarian food products commonly recommended during Hindu fasting:

1. Sama Rice (Barnyard Millet): Sama rice, also known as samvat rice or barnyard millet, is a popular grain used during fasting. It's cooked similarly to rice and forms the base of various dishes.

2. Singhare ka atta (Water Chestnut Flour): This flour is widely used in making puris (fried Indian bread) or parathas (flatbreads) during fasting periods.

3. Sabudana (Tapioca Pearls): Sabudana is a common ingredient used in making dishes like sabudana khichdi (a savory dish), sabudana vada (fried snacks), and sabudana kheer (dessert).

4. Kuttu ka atta (Buckwheat Flour): Buckwheat flour is used to make rotis (flatbreads), pakoras (fritters), and other dishes during fasting.

5. Rock Salt (Sendha Namak): Regular salt is avoided during fasting, and instead, rock salt (sendha namak) is used as a substitute in cooking.

6. Dairy Products: Milk, yogurt (curd), paneer (cottage cheese), and buttermilk are commonly consumed during fasting.

7. Fresh Fruits: Fruits like bananas, apples, oranges, pomegranates, and grapes are permitted during Hindu fasting.

8. Potatoes: Potatoes are often used in various forms, such as boiled or mashed, and are a common ingredient during fasting.

9. Nuts and Seeds: Almonds, cashews, peanuts, pumpkin seeds, and coconut are often consumed as snacks or used in recipes.

10. Ghee (Clarified Butter): Ghee is considered permissible during fasting and is used in cooking or as a topping for certain dishes.

11. Herbs and Spices: Herbs like cilantro, mint, and spices such as cumin seeds, ginger, green chilies, and black pepper are used to flavor fasting dishes.

12. Beverages: Water, herbal teas, coconut water, and fruit juices without added sugars are generally allowed.

When observing Hindu fasting practices, it's essential to follow individual beliefs and customs. The specific food items allowed can vary based on regional traditions and personal preferences. Consulting with family elders or religious authorities can provide further guidance regarding fasting foods and practices.
