Vegetarian Diets & Women’s Wellbeing:

Protein and Key Nutrients to Consider

More and more women choose vegetarian or vegan diets for ethical, environmental, cultural or personal reasons. A well-planned plant-based diet can be varied, nourishing and compatible with a healthy lifestyle.

At the same time, some women I meet in my practice are concerned about fatigue, changes in hair or skin, energy levels, cravings or changes in their menstrual cycle. These experiences can have many different causes and should not automatically be attributed to diet.

However, they can be a useful opportunity to look at whether the overall diet is providing enough energy, protein and essential nutrients.

This can be particularly relevant during periods of change such as the reproductive years, perimenopause and menopause.

Is a Vegetarian Diet Healthy for Women?

There is no single “vegetarian diet.”

A vegetarian diet may include eggs and dairy products, while a vegan diet excludes all animal-derived foods. The nutritional considerations can therefore be quite different.

A well-planned vegetarian diet can provide adequate protein, fibre, vitamins and minerals. However, when certain food groups are excluded, some nutrients may require more deliberate planning.

Depending on the individual dietary pattern, particular attention may be appropriate for nutrients such as:

  • protein
  • vitamin B12
  • iron
  • zinc
  • iodine
  • calcium
  • omega-3 fatty acids

The more restrictive the diet, the more important nutritional variety and planning become. For people following a vegan diet, vitamin B12 deserves particular attention because reliable sources generally come from fortified foods or supplementation.

Why Protein Matters

Protein contributes to the maintenance and repair of body tissues and is particularly important for maintaining muscle mass.

This becomes increasingly relevant during midlife, when maintaining muscle strength and physical activity is an important part of healthy ageing.

Plant foods can absolutely contribute substantial amounts of protein. Examples include:

  • lentils and beans
  • chickpeas
  • tofu and tempeh
  • seitan
  • quinoa
  • nuts and seeds
  • dairy products and eggs for vegetarians who include them

Plant proteins differ in their amino-acid composition and digestibility, but a varied vegetarian or vegan diet can provide the essential amino acids the body needs.

Rather than trying to create a “perfect” protein combination at every meal, the more practical approach is to include a variety of protein-rich foods throughout the day.

Simple Food Combinations

Traditional cuisines already offer many examples:

  • rice and lentils
  • chickpeas with wholegrain bread
  • hummus with wholegrain pita
  • beans with grains
  • oats with yoghurt and seeds
  • tofu with rice and vegetables

The goal is not perfection. It is variety, adequacy and consistency.

​Iron: A Nutrient Worth Paying Attention To

Iron is particularly relevant for women who menstruate.

Plant foods contain non-heme iron, which is generally absorbed differently from the heme iron found in animal foods.

This does not mean that vegetarian women cannot obtain adequate iron from their diet. Plant sources include:

  • lentils
  • chickpeas
  • beans
  • tofu
  • pumpkin seeds
  • nuts
  • whole grains
  • dark green vegetables
  • fortified foods

Including vitamin-C-rich foods alongside plant sources of iron can help support iron absorption.

If you experience persistent fatigue, significant hair loss, heavy periods or other concerning symptoms, it is important not to assume that diet is the cause. A healthcare professional can determine whether further assessment or blood testing is appropriate.

Vitamin B12 and Plant-Based Diets

Vitamin B12 deserves particular attention when animal products are significantly reduced or eliminated.

Vegetarians who regularly consume eggs and dairy may obtain B12 from these foods, although individual intake varies.

For people following a vegan diet, a reliable source of vitamin B12 through fortified foods and/or supplementation is generally necessary.

This is an important example of why a healthy dietary pattern also needs to be a nutritionally adequate one.

Other Nutrients to Consider

Depending on the foods included in your diet, it can also be useful to consider zinc, iodine, calcium and omega-3 fatty acids.

Zinc

Zinc can be found in legumes, nuts, seeds and whole grains. Including a variety of these foods can contribute to an adequate intake.

Iodine

Iodine is an essential nutrient involved in normal thyroid function. Its availability in plant-based diets can vary considerably, so individual dietary patterns matter.

Calcium

Vegetarians may obtain calcium from dairy products, while fortified plant drinks, calcium-set tofu and other fortified foods can be useful options for vegans.

Omega-3 Fatty Acids

Plant sources include walnuts, chia seeds, flaxseeds and hemp seeds. Algae-based DHA and EPA products are another option sometimes considered by people following vegan diets.

If you are considering nutritional supplementation, particularly with nutrients such as iron or iodine, it is appropriate to discuss your individual needs with a qualified healthcare professional.

What About Vegetarian Diets and Women’s Hormonal Health?

This is an area where it is particularly important to avoid oversimplifying.

Menstrual cycles and women’s health are influenced by many factors, including:

  • overall energy intake
  • nutritional adequacy
  • physical activity
  • sleep
  • stress
  • reproductive stage
  • individual health factors

There is no single food that “balances hormones,” and there is no need for every woman to consume animal products in order to support her wellbeing.

At the same time, an overly restrictive or poorly planned diet may make it more difficult for some women to meet their nutritional and energy requirements.

A more useful question than “Should I eat meat?” is:

“Is my current dietary pattern providing enough energy, protein and essential nutrients for my individual needs?”

What If Your Menstrual Cycle Changes?

Changes in the menstrual cycle can have many possible causes.

Significant changes in energy intake, body weight, physical activity, stress and nutritional status may be relevant in some women, while other menstrual changes may have medical causes requiring assessment.

If your periods become very irregular, unusually heavy, significantly more painful or stop altogether, it is important to discuss these changes with your doctor or another appropriately qualified healthcare professional.

Nutritional and lifestyle support can be complementary to medical care, but should not replace medical evaluation or treatment.

A Practical Approach to Vegetarian Nutrition

Rather than focusing on whether individual foods are “good” or “bad” for hormones, it can be more useful to look at the overall dietary pattern.

A balanced vegetarian meal might include:

Protein:
lentils, beans, tofu, tempeh, eggs, yoghurt or another suitable protein source

Complex carbohydrates:
oats, quinoa, rice, potatoes or wholegrain bread

Vegetables and fruit:
a variety of colours and types

Healthy fats:
extra-virgin olive oil, nuts, seeds or avocado

Key nutrients:
a variety of foods providing iron, zinc, calcium, iodine, B12 and omega-3 fatty acids according to your individual dietary pattern

The goal is not to follow a perfect diet. It is to develop a varied, sustainable and nutritionally adequate way of eating.

Supporting Women’s Wellbeing in My Practice in Turin & Online

In my practice, I work with women who want to better understand how nutrition and lifestyle can support their overall wellbeing during different stages of life, including the menstrual years, perimenopause and menopause.

My approach may include:

  • nutrition and lifestyle education
  • discussion of meal structure and protein intake
  • support for sustainable lifestyle habits
  • sleep and circadian-rhythm strategies
  • nervous-system regulation practices
  • general wellbeing education

Where symptoms suggest that medical assessment may be appropriate, I encourage collaboration with the woman’s doctor or another appropriately qualified healthcare professional.

My role is not to diagnose or treat medical conditions, but to provide complementary wellbeing education and support within my professional scope.

The Bottom Line

A vegetarian or vegan diet does not automatically mean poor health, and eating animal products does not automatically guarantee good health.

What matters is whether the overall dietary pattern provides adequate energy, protein and essential nutrients while remaining varied and sustainable.

For women following vegetarian or vegan diets, thoughtful nutritional planning can be particularly valuable during periods of physiological change.

And when symptoms arise, looking at the whole picture, including nutrition, lifestyle, sleep, stress and medical factors, can provide a more useful starting point than blaming a single food or dietary choice.
