This page answers those in turn. The evidence behind period nutrition is thinner than many wellness sites suggest, so each answer says where the support is reasonable and where it is merely hopeful.
What should you eat during periods?
Regular, balanced meals built around whole grains, dal or another protein, vegetables and fruit, with iron-rich food at least once a day and a source of vitamin C beside it. There is no special period diet. The body's needs during menstruation are much the same as at any other time, with two that deserve extra attention: iron, because blood is lost, and fluid, because tiredness and headaches are worse when you are dehydrated. Skipping meals through low appetite or nausea tends to make fatigue and low mood worse, so small, frequent meals are fine if large ones feel heavy.
Which foods help with period cramps?
Ginger has the best evidence among foods, and even that is modest. Period cramps are driven largely by prostaglandins, chemical messengers that make the muscle of the uterus contract, and ginger appears to damp down their production. Several small trials found that powdered ginger taken in the first days of a period reduced pain compared with a placebo, and in a couple it performed about as well as common painkillers. The trials were short, and most used measured doses of dried ginger in capsules, roughly one to two grams a day, which is more than a cup of adrak chai provides. Ginger tea is harmless to try.
Does omega-3 help period pain?
There is some supporting evidence, though it is not strong. Omega-3 fats are thought to shift the body's prostaglandin balance towards less inflammatory forms, and a number of small trials reported less menstrual pain in women taking fish oil for two or three months. None is large. Eating an oily fish such as mackerel (bangda) or sardines (mathi) once or twice a week is a good habit whatever it does for cramps. Vegetarians get a plant form from flaxseed, walnuts and chia, though the body converts it poorly; the page on omega-3 foods and capsules compares the sources.
Is magnesium good for period cramps?
The evidence for magnesium is weaker than for ginger. A few small, older trials suggested supplements might ease cramps, and reviews have described magnesium as promising but unproven, because the trials were few and small. Magnesium from food is a different matter, since a diet with enough of it is healthy in any case: nuts, seeds, whole grains, dal, green leafy vegetables and dark chocolate all contribute. Supplements taken on your own can cause loose stools and are unsuitable for people with kidney disease, so they are worth discussing with a doctor first.
How much iron do women lose during periods?
An average period loses roughly 30 to 40 ml of blood, which carries somewhere around 15 mg of iron, and heavy periods lose far more. That monthly loss is why ICMR-NIN (Nutrient Requirements for Indians, 2020) sets the recommended iron intake for adult women at 29 mg a day, against 19 mg for men. Few Indian diets reach it. NFHS-5, the National Family Health Survey of 2019 to 2021, found about 57 per cent of Indian women aged 15 to 49 to be anaemic. Tiredness, breathlessness on the stairs, pale skin and brittle nails can all be early signs.
Which iron-rich foods should you eat during periods?
Pulses, green leafy vegetables such as amaranth and drumstick leaves, sesame and garden cress seeds, eggs, and meat, liver and fish are the main sources, and the full list with amounts is on the page about iron-rich Indian foods. The more useful trick during a period is pairing. Iron from plants is absorbed poorly on its own, and vitamin C eaten in the same meal raises its absorption markedly: a squeeze of lemon on dal, amla or guava after lunch, tomato in the sabzi. Tea and coffee do the opposite, so keep them an hour away from iron-rich meals.
Getting more out of the iron you eat
Pairing matters as much as the source does, because iron from plants is absorbed poorly on its own.
Put an iron food in every day
Pulses, amaranth and drumstick leaves, sesame and garden cress seeds, eggs, and meat, liver or fish. Daily beats a large effort once a month.
Add vitamin C to the same meal
A squeeze of lemon over dal, tomato in the sabzi, or amla or guava after lunch raises absorption from plant foods markedly.
Move tea and coffee away from it
Keep them about an hour clear of an iron-rich meal, since their tannins work in the opposite direction.
Test before you supplement
Tablets taken on a hunch bring constipation and stomach upset, and too much iron over years does harm. Ask for a haemoglobin test if you are always exhausted around your period.
Should you take iron tablets during periods?
Only if a blood test shows you need them, or a doctor advises it. Iron supplements taken on a hunch can cause constipation and stomach upset, and too much iron over a long time does harm. Diagnosed anaemia usually needs tablets as well as diet, because food alone rebuilds iron stores slowly. India's anaemia programme supplies weekly iron and folic acid tablets to adolescent girls through schools and health centres. If you are always exhausted around your period, ask for a haemoglobin test; the anaemia diet chart explains how food supports treatment once the cause is known.
Does salt make period bloating worse?
It can add to it. Hormonal changes before and during a period make the body hold on to water, and a salty diet encourages further retention in some people. Cutting back on pickles, papad, namkeen, instant noodles and packaged snacks in the week before a period is a sensible experiment, though good trials on salt and period bloating specifically are lacking. Drinking enough water helps rather than hinders, and potassium-rich foods such as banana, coconut water, curd and dal help the body balance its sodium.
Is coffee bad during periods?
Not for most people in moderate amounts. Some women find that caffeine worsens breast tenderness, anxiety or poor sleep in the days before a period, and it can loosen stools that are already loose, so cutting down is worth trying if those symptoms bother you. The evidence that caffeine worsens cramps is inconsistent. Two cups of tea or coffee a day, kept away from iron-rich meals, is a reasonable limit. Energy drinks and colas add sugar as well as caffeine, and are the first thing to drop.
Why do you crave chocolate before your period?
The cravings are real and common, linked to the hormonal shifts of the second half of the cycle, to mood changes, and to a small rise in energy use that some studies have measured. Wanting something sweet is not a failing. A square or two of dark chocolate with a high cocoa content brings some magnesium and iron along with the pleasure, and the page on dark chocolate benefits explains how much is sensible. Eating sweets with a meal, rather than on their own, keeps the rise in blood sugar smaller.
Should you avoid curd, sour or cold food during periods?
No. There is no evidence that curd, lemon, tamarind, cold water or food from the fridge increases bleeding or cramps, and these rules often remove good sources of protein, calcium and vitamin C. Warm drinks can feel soothing, and a hot water bag on the lower belly genuinely eases cramps, so choosing a warm meal is fine on comfort grounds. Traditional drinks such as ajwain or jeera water are harmless but largely untested for period pain. Eat what agrees with you.
When are period symptoms a sign of something more?
See a gynaecologist if you soak through a pad every hour or two for several hours in a row, pass clots bigger than a coin, bleed for more than seven days, have pain severe enough to keep you from work or college, or notice your cycle becoming irregular, much shorter or much longer than usual. Bleeding between periods or after sex also needs checking. These can point to PCOS, fibroids, endometriosis, thyroid disease or a bleeding disorder, each of which needs diagnosis and treatment that food cannot provide. Dizziness, fainting or a racing heart during a heavy period needs urgent care. Where PCOS is confirmed, the PCOS diet plan sets out the eating side.
Where women's health nutrition goes deeper
Periods, iron status and hormonal conditions sit side by side in everyday women's health practice, and one-size diet sheets serve them poorly. NNWA's Women's Health and PCOS Nutrition course spends six weeks at intermediate level on understanding PCOS, diet and hormonal balance, menstrual and fertility nutrition, pregnancy and lactation, menopause and bone health, and iron and other common deficiencies. The fee is 9,999 rupees against an original 14,999, with EMI at 1,667 rupees a month, and the course carries NNWA certificates.
The short version
Eat normal, regular meals during your period, with iron-rich food every day and vitamin C beside it, since monthly blood loss and widespread anaemia make iron the priority. Ginger has modest evidence for cramps, omega-3 some, and magnesium less. Go easy on salt if you bloat, keep caffeine moderate, drink water and enjoy a little dark chocolate without guilt. Pain that stops your life, heavy bleeding or a changing cycle deserves a gynaecologist rather than another remedy.
