Roz suni jaane wali food baaton ko hum science ke saath check karte hain — myth kya hai, evidence kya kehta hai, aur BhojVigyan ka simple take kya hai. Har card par source aur reviewed date di gayi hai.
Everyday Eating
मसालेदार खाना पेट के अल्सर का कारण बनता है।
What science says: Most stomach (peptic) ulcers are linked to Helicobacter pylori infection or regular use of non‑steroidal anti‑inflammatory drugs (NSAIDs). Spicy foods do not cause ulcers, though they can irritate the stomach and make symptoms worse for some people.
Meal Timing
चाय या कॉफ़ी खाने के साथ पीने से लोहा (आयरन) बिलकुल भी अवशोषित नहीं होता, इसलिए इन्हें कभी भोजन के साथ नहीं पीना चाहिए।
What science says: There is good evidence that compounds in tea and coffee can reduce the body’s absorption of non‑heme (plant‑based) iron when consumed with meals. The NHS advises people with low iron or anaemia to avoid drinking tea or coffee with food because this can lower the iron you get from a meal. This does not mean all iron is lost, but timing drinks away from meals can help increase iron uptake for those at risk.
Everyday Eating
ठंडी चीज़ें या ठंडा पानी/आइसक्रीम खाने से जुकाम, खांसी या गले में इंफेक्शन हो जाता है।
What science says: Common colds and most sore throats are caused by viruses that spread from person to person; they are not caused by eating cold foods or drinking cold beverages. Exposure to cold temperatures or chilled drinks may make some people notice throat irritation, but that is not the same as contracting a viral infection. (For more on causes of the common cold, see the NHS guidance.)
Carbs & Grains
चावल खाने से वज़न बढ़ता है।
What science says: No single food decides body weight on its own. Overall energy intake, portion sizes, activity and sleep matter far more than whether the grain on the plate is rice or wheat. Rice, like roti, is a source of carbohydrate; whole-grain options add more fibre.
Everyday Eating
हेल्दी खाना मतलब सिर्फ़ बाउल, सलाद और स्मूदी।
What science says: Dietary guidance is about the overall pattern — enough vegetables, pulses/protein, whole grains and limited added sugar, salt and deep-fried food. Normal Indian home meals such as roti-sabzi, dal-rice, khichdi, poha or chilla can meet that pattern.
Protein
शाकाहारी भारतीय खाने में प्रोटीन पूरा नहीं होता।
What science says: Dals, rajma, chana, soy, paneer, curd, milk, peanuts and seeds all supply protein. Eating a variety of pulses and grains across the day generally covers the amino acids most people need.
Fats & Oils
हेल्दी खाने से घी पूरी तरह हटा देना चाहिए।
What science says: Ghee is a concentrated source of energy and saturated fat. Guidance is to keep total fat and saturated fat within moderate limits, not to declare any traditional fat forbidden. Very large amounts of any fat add up quickly in calories.
Hydration
डिटॉक्स ड्रिंक शरीर से टॉक्सिन निकालते हैं।
What science says: There is no good evidence that any drink 'detoxes' the body. The liver and kidneys already handle waste products. Fruit juices also concentrate sugar with less fibre than whole fruit.
Meal Timing
रात का खाना छोड़ना हेल्दी तरीक़ा है।
What science says: Evidence on meal timing is mixed and highly individual. Skipping meals often leads to stronger hunger later and can make it harder to meet protein, fibre and micronutrient needs — particularly for children, older adults, pregnant women and people on medication.
Hydration
खाने के बीच पानी पीने से पाचन बिगड़ता है।
What science says: There is no good evidence that sipping water with food weakens digestion. Digestive juices are secreted continuously and the stomach adjusts its contents; water can even help swallowing and fibre movement.
Carbs & Grains
वज़न बढ़ने की वजह कार्बोहाइड्रेट है।
What science says: Weight change tracks total energy balance over time, not one nutrient. Carbohydrate-rich staples are the base of most healthy world diets; refined snacks, sugary drinks and fried food add energy quickly with little fibre.
Meal Timing
8 बजे के बाद खाया हुआ सब चर्बी बन जाता है।
What science says: The clock does not change how food is metabolised by itself. Late eating is often linked with weight gain because portions are larger, snacking is less mindful and sleep is shorter — not because of the hour alone.
Sugar & Sweeteners
गुड़ और ब्राउन शुगर, चीनी से हेल्दी हैं।
What science says: Jaggery, brown sugar, coconut sugar and white sugar are all free sugars with similar energy. Trace minerals in jaggery are too small at normal serving sizes to change the overall picture.
Sugar & Sweeteners
शहद नैचुरल है, इसलिए जितना चाहें खा सकते हैं।
What science says: Honey counts as a free sugar in dietary guidance. It is roughly as energy-dense as sugar and raises blood glucose. Honey should also never be given to infants under 12 months.
Fruits
खाने के बाद फल खाने से पेट में सड़न होती है।
What science says: Food does not putrefy in a healthy stomach; acid and enzymes digest mixed meals routinely. Food-combining rules of this kind are not supported by evidence.
Fruits
रात में फल खाना नुक़सानदेह है।
What science says: Most people can eat fruit in the evening without any problem. Fruit contributes fibre, potassium and vitamins; whole fruit at any hour beats a fried or sugary snack.
Everyday Eating
कोलेस्ट्रॉल की वजह से अंडे नहीं खाने चाहिए।
What science says: For most people, dietary cholesterol has a smaller effect on blood cholesterol than saturated and trans fats do. Modern guidance focuses on overall fat quality and the whole eating pattern. People with existing heart disease, diabetes or high cholesterol should follow their clinician's personal advice.
Protein
प्रोटीन सिर्फ़ जिम जाने वालों के लिए है।
What science says: Protein is needed by everyone for muscle maintenance, immune function and repair. Needs are relatively higher during growth, pregnancy, recovery and older age, when muscle loss becomes a concern.
Protein
शाकाहारी प्रोटीन 'अधूरा' होता है।
What science says: Individual plant foods differ in amino-acid profile, but mixed diets — dal with rice or roti, chana with wheat, soy, curd, milk — supply the full range across the day. Soy and dairy are complete on their own.
Meal Timing
नाश्ता छोड़ना हमेशा नुक़सान करता है।
What science says: Evidence here is mixed. Breakfast skippers do not automatically have a 'slower metabolism'; observational links with weight are confounded by other habits. What breakfast eaters do gain is an extra chance to get protein, fibre and micronutrients — which matters a lot for children and adolescents.
Hydration
नींबू पानी चर्बी जलाता है।
What science says: No drink burns fat. Lemon water is mostly water with a little vitamin C and negligible energy. Any benefit people notice usually comes from drinking more water instead of sugary drinks.
Hydration
गर्म पानी शरीर की चर्बी पिघला देता है।
What science says: Body fat is not melted by warm liquids; it is used as energy when intake is lower than expenditure. Water temperature changes energy use only trivially.
Fats & Oils
घी परंपरागत है, इसलिए जितना भी खा लें।
What science says: Ghee supplies about 9 kcal per gram and is high in saturated fat. Guidance is to keep saturated fat within moderate limits and to keep total fat in check regardless of the source.
Fats & Oils
सारे फैट ख़राब होते हैं।
What science says: Fat is needed for essential fatty acids and fat-soluble vitamins. Guidance distinguishes types: replace saturated and industrial trans fats with unsaturated fats from nuts, seeds, mustard/groundnut/rice-bran oils and fish, and avoid partially hydrogenated fats.
Fruits
डायबिटीज़ में फल पूरी तरह बंद कर देने चाहिए।
What science says: Whole fruit is generally included in diabetes-friendly eating patterns; its fibre and water content moderate the glucose response compared with juice or sweets. Portion size, spacing across the day and individual response still matter, and medication plans differ from person to person.
Salt & Labels
गुलाबी/सेंधा नमक, आम नमक से बहुत हेल्दी है।
What science says: All of these are largely sodium chloride, and health guidance targets total sodium — under 5 g of salt a day for adults. Speciality salts contain only trace minerals. Importantly, many are not iodised, while iodised salt protects against iodine deficiency.
Salt & Labels
ग्लूटेन-फ्री खाना सबके लिए हेल्दी है।
What science says: A gluten-free diet is medically necessary for coeliac disease and helps people with diagnosed gluten sensitivity or wheat allergy. For everyone else there is no proven advantage, and many packaged gluten-free products are more processed and lower in fibre.
Everyday Eating
बड़ों को दूध पूरी तरह छोड़ देना चाहिए।
What science says: Milk and curd supply protein, calcium and vitamin B12 and are part of many national dietary guidelines. Some adults are lactose intolerant and manage better with curd, buttermilk, paneer or lactose-free options; that is an individual tolerance issue, not a universal rule.
Everyday Eating
हेल्दी रहने के लिए सबको सप्लीमेंट या डिटॉक्स चाय चाहिए।
What science says: Most nutrients are best obtained from a varied diet. Supplements are useful for specific documented deficiencies or life stages (for example iron and folic acid in pregnancy, B12 for some vegetarians) and should be guided by testing and a clinician. Some products can interact with medicines.
