Sources, with dates

No figure without a source line, no source line without a date — and no claim of a review that did not happen.

এই পাতাটি কী

এই পাতায় নাম-উল্লেখ করা সূত্র থেকে নেওয়া রেফারেন্স সংখ্যা প্রকাশ করা হয়। এটি তথ্য, চিকিৎসাগত পরামর্শ নয়, এবং এটি আপনার নিজের রোগ-ইতিহাস হিসেবে ধরতে পারে না — ডাক্তার পারেন। সূত্র & সেগুলি আমরা কীভাবে যাচাই করি →

উপবাস সবার জন্য নিরাপদ নয়। ডাক্তারের সঙ্গে কথা বলুন ব্রতের আগে , পালনের মাঝপথে নয় — যদি আপনি গর্ভবতী বা স্তন্যদাত্রী হন, ডায়াবেটিস থাকে — বিশেষত ইনসুলিন বা সালফোনাইলইউরিয়া চললে — খাদ্যাভ্যাসজনিত সমস্যার ইতিহাস থাকে, আপনি বয়স্ক বা শিশু হন, অথবা নিয়মিত ওষুধ খান। এখানে বর্ণিত প্রতিটি রীতিতেই যাঁরা উপবাস করতে পারেন না, তাঁদের জন্য ছাড়ের ব্যবস্থা আগে থেকেই রয়েছে। সম্পূর্ণ তালিকা, আর কী কী দেখে নিতে হবে →

Food composition

Food composition sources, with what each is used for. CHECKED · JUL 2026
সূত্র	Published	Last checked	What it is used for
Indian Food Composition Tables 2017 Longvah T, Ananthan R, Bhaskarachary K, Venkaiah K. National Institute of Nutrition, ICMR, Hyderabad.	2017	জুলাই 2026	The primary source for every food value on this site that IFCT carries. Available carbohydrate is published directly, so nothing has to be converted.
Nutritive Value of Indian Foods Gopalan C, Rama Sastri BV, Balasubramanian SC. National Institute of Nutrition, ICMR, Hyderabad.	revised editions	জুলাই 2026	The older ICMR–NIN tables, used only where IFCT 2017 has no row and the older analysis does.
FoodData Central, SR Legacy U.S. Department of Agriculture, Agricultural Research Service.	SR Legacy release	জুলাই 2026	Used for foods no Indian table carries — buckwheat, water chestnut flour, sago, fox nut. USDA publishes carbohydrate by difference, so fibre is subtracted here and the subtraction is stated on the food's page.
ThaliFacts dataset Sibling property, thali.amit.marketing.	জুলাই 2026	জুলাই 2026	Shared rows for foods both sites carry, so the two can never disagree about what a katori of curd holds.

Observances

Observances sources, with what each is used for. CHECKED · JUL 2026
সূত্র	Published	Last checked	What it is used for
Published accounts of each observance Reference works and community descriptions of the practice, read against each other.	various	জুলাই 2026	Every observance page is written as commonly observed and attributed to practice, not to authority. Where accounts differ, the page says they differ rather than choosing one.
The panchang itself Your own community's announced panchang or timetable.	local	n/a	Deliberately NOT reproduced here. Dates, sehri, iftar, moonrise and sunset are local and religiously significant; this site publishes none of them and sends you to the correct source.

Safety and physiology

Safety and physiology sources, with what each is used for. CHECKED · JUL 2026
সূত্র	Published	Last checked	What it is used for
General, conservative practice Written to the cautious end of ordinary clinical advice.	n/a	জুলাই 2026	The guides describe well-established, low-controversy ground — hydration, medication timing, protein adequacy, blood-glucose caution — and are phrased as ranges and options, never as a protocol or a dose.
No clinical trial is cited as evidence for an individual claim Stated plainly rather than dressed up.	—	জুলাই 2026	This site does not publish a systematic reading of the fasting literature, and it does not pretend to. Anything that would depend on one is referred to a doctor instead.

What is deliberately not here

No times. Sehri, iftar, moonrise, sunset and the start and end of any fast are absent by design, and the build refuses to ship a page that renders a clock time outside the personal intermittent-fasting calculator.
No ruling on observance. What your tradition requires is not a question this site can answer, and it does not try. Practice is reported and attributed; where regions differ, the difference is printed rather than resolved.
No point claims on anything clinical. Physiological figures are given as ranges, with the variance named, because a single number implies a precision nobody has for an individual reader.
No claim of medical review. Emitting one in the markup while nobody had reviewed the page would be a lie told to a machine, which is the worst kind.

Questions about the sources

Is VratFuel medically reviewed?

No, and it does not claim to be. It publishes food composition figures from named tables with the citation given, and describes observances as commonly observed. Guidance about your own body belongs with a clinician who knows your history.

Is VratFuel a religious authority?

No. Religious observance is not medical advice and it is not this site's to adjudicate. What each vrat traditionally permits is reported and attributed to practice; where traditions differ, the page says they differ rather than flattening them into one correct version.

How often are the sources checked?

The composition tables were last read line by line in the July 2026 audit, which is the date printed on every source line. Observance descriptions are re-read whenever a correction arrives, and corrections about how a practice is described are prioritised above corrections to numbers.

What if a source here is wrong?

Tell me and it will be fixed on the next build, with the correction described rather than quietly applied. That is the entire mechanism — there is no editorial board behind this site and pretending otherwise would be the dishonest part.

Practices are described as সাধারণভাবে দেখা যায়; customs differ by family, region, community and sampradaya, and this site is not an authority on any of them. Food values come from the Indian Food Composition Tables 2017 (ICMR–NIN), the older ICMR–NIN tables, USDA FoodData Central, named composition studies and the shared ThaliFacts dataset, reconciled against Atwater factors on every build. Which source applies to which food is listed per food, and every source carries the date it was last checked. General information only — not medical or religious guidance. Fasting is not safe for everyone, particularly during pregnancy or with diabetes or other conditions. Speak to a doctor first.
