Nutrition and Menstrual Health

Introduction

Good nutrition plays an important role in menstrual health and overall wellbeing. The foods and drinks you consume can affect your energy levels, support healthy blood production, help maintain strong bones and contribute to your general health throughout the menstrual cycle.

People who experience heavy menstrual bleeding are at greater risk of losing significant amounts of iron, which can lead to iron deficiency and anaemia. Eating a balanced diet and staying well hydrated can help support your body’s needs before, during and after menstruation.

Although healthy eating cannot prevent every menstrual problem, it is an important part of maintaining good reproductive health.

Why Does Nutrition Matter During Menstruation?

During menstruation, your body loses blood, and with it, small amounts of iron. For most people, this loss is easily replaced through a balanced diet.

However, people with heavy menstrual bleeding may lose more iron than their body can replace, increasing the risk of iron deficiency and anaemia.

Good nutrition can help:

•	support healthy blood production;
•	maintain energy levels;
•	strengthen the immune system;
•	support normal body functions;
•	maintain strong bones; and
•	promote overall wellbeing.

Iron and Menstrual Health

Iron is a mineral that helps the body produce haemoglobin, a protein in red blood cells that carries oxygen around the body.

When the body does not have enough iron, it cannot produce enough healthy red blood cells, which may lead to iron deficiency anaemia.

Anaemia is a condition in which the body does not have enough healthy red blood cells or haemoglobin to carry adequate oxygen around the body.

People who have heavy or prolonged periods are more likely to develop iron deficiency.

Signs of Iron Deficiency and Anaemia

Iron deficiency often develops gradually.

Common signs and symptoms include:

•	feeling unusually tired or weak;
•	dizziness or light-headedness;
•	headaches;
•	shortness of breath during normal activities;
•	pale skin;
•	cold hands and feet;
•	difficulty concentrating; and
•	a fast or irregular heartbeat in more severe cases.

If you experience these symptoms, particularly alongside heavy menstrual bleeding, consult a healthcare professional.

Iron-Rich Foods

Including iron-rich foods in your diet can help replace the iron lost during menstruation.

Animal sources

•	lean red meat;
•	liver (consumed occasionally);
•	chicken;
•	fish; and
•	eggs.

Plant sources

•	beans;
•	peas;
•	lentils;
•	soybeans;
•	groundnuts;
•	pumpkin seeds;
•	dark green leafy vegetables such as spinach, sukuma wiki and amaranth; and
•	iron-fortified cereals, where available.

Plant-based iron is healthy but is not absorbed as easily as iron from animal foods.

Vitamin C Helps Your Body Absorb Iron

Vitamin C helps the body absorb iron more effectively, especially from plant-based foods.

Good sources of vitamin C include:

•	oranges;
•	lemons;
•	mangoes;
•	guavas;
•	pineapples;
•	tomatoes;
•	bell peppers; and
•	broccoli.

For example, eating beans together with tomatoes or having a fresh orange or guava with an iron-rich meal may improve iron absorption.

Foods and Drinks That Can Reduce Iron Absorption

Some foods and drinks can reduce the amount of iron your body absorbs if consumed with meals.

These include:

•	tea;
•	coffee; and
•	large amounts of calcium-rich foods or calcium supplements taken at the same time as an iron-rich meal.

You do not need to avoid these foods completely, but it may help to consume them at a different time from your main iron-rich meals if you have iron deficiency.

Staying Hydrated

Drinking enough water is important throughout the menstrual cycle.

Staying hydrated:

•	supports normal body functions;
•	helps replace fluids lost through sweating and daily activities;
•	supports concentration; and
•	may help some people feel more comfortable during their period.

Aim to drink water regularly throughout the day, especially in hot weather or during physical activity.

Calcium and Vitamin D

Calcium and vitamin D help maintain strong bones.

This becomes especially important during adolescence, when bones are still developing, and after menopause, when lower oestrogen levels increase the risk of osteoporosis.

Good sources of calcium include:

•	milk;
•	yoghurt;
•	cheese;
•	small fish eaten with their bones;
•	fortified foods; and
•	some green leafy vegetables.

The body produces vitamin D when the skin is exposed to sunlight. Vitamin D is also found in a small number of foods, including oily fish and fortified products.

Can Food Help Reduce Menstrual Symptoms?

Some people find that healthy eating helps them feel better during their period.

While there is no single “period diet,” the following may support overall wellbeing:

•	eating regular, balanced meals;
•	choosing whole grains;
•	including fruits and vegetables every day;
•	eating enough protein;
•	limiting foods high in salt if bloating is a concern; and
•	drinking enough water.

Everyone’s experience is different, and no specific food has been proven to eliminate menstrual cramps or other menstrual symptoms completely.

What About Sugar, Caffeine and Alcohol?

Some people notice that certain foods or drinks seem to affect how they feel during their period.

Sugar

Eating large amounts of foods and drinks high in added sugars may contribute to fluctuations in energy levels. It is best to enjoy sugary foods in moderation as part of a balanced diet.

Caffeine

Tea, coffee and energy drinks contain caffeine.

Some people find that caffeine worsens symptoms such as anxiety, breast tenderness or difficulty sleeping, while others notice little or no difference. Research on caffeine and menstrual symptoms is mixed, and its effects vary between individuals.

If you think caffeine affects your symptoms, consider reducing your intake and see whether it helps.

Alcohol

Alcohol can affect sleep, contribute to dehydration and may worsen headaches or mood symptoms for some people.

Limiting alcohol is recommended for overall health.

Do I Need Supplements?

Most people can obtain the nutrients they need through a balanced diet.

However, a healthcare professional may recommend supplements if you have:

•	iron deficiency or anaemia;
•	vitamin D deficiency;
•	calcium deficiency; or
•	another nutritional deficiency.

Do not start taking supplements without medical advice, especially iron supplements, as taking too much iron can be harmful.

Healthy Lifestyle Habits That Support Menstrual Health

Good menstrual health involves more than nutrition alone.

Healthy habits include:

•	eating a balanced diet;
•	staying physically active;
•	drinking enough water;
•	getting adequate sleep;
•	managing stress; and
•	attending regular healthcare check-ups when needed.

When Should You See a Healthcare Professional?

Consult a healthcare professional if you:

•	have heavy menstrual bleeding;
•	experience symptoms of iron deficiency or anaemia;
•	feel unusually tired for a prolonged period;
•	become dizzy or faint during your period;
•	think you may need nutritional supplements; or
•	have concerns about your diet and menstrual health.
