Vegan Diets: Changing Periods And Hormonal Cycles?

There is no conclusive research on how a vegan diet impacts the menstrual cycle. However, some studies suggest that a vegan diet can affect the length of a person's cycle, amplify PMS symptoms, and cause iron deficiency.

A vegan diet is often associated with lower body weight and higher physical activity levels, which can lead to disturbances in the menstrual cycle or amenorrhea (the cessation of the menstrual period) if calorie intake is too low.

Vegetarians may experience more PMS symptoms, such as depression, panic attacks, and insomnia, possibly due to differences in iron levels or other nutrient deficiencies.

Iron deficiency is common among vegans and vegetarians, especially women, as meat contains higher levels of iron than plant-based foods. This can lead to various health issues, including a weakened immune system, increased risk of pregnancy complications, fatigue, dizziness, and more.

While a vegan diet can provide health benefits such as a decreased risk of obesity, diabetes, and cancer, it is important to ensure proper planning and diversity in the diet to avoid potential negative impacts on the menstrual cycle.

A vegan diet may affect the length of your cycle

There is limited research on how a vegan diet affects the menstrual cycle. However, there is evidence that a vegan diet may impact the length of your cycle, but only in more extreme cases. Research shows that people with a meat-free diet are more likely to have a lower body weight and be more physically active. Extreme caloric restriction can affect cycle length or stop menstruation altogether.

Lower body weight and increased physical activity

A vegan diet is often associated with a lower body weight and increased physical activity. This can impact the length of your cycle, as extreme caloric restriction can disrupt the normal hormonal balance and lead to shorter or longer cycles. However, it is important to note that a well-planned vegan diet that meets daily caloric needs can support a regular cycle.

Iron deficiency

Iron deficiency is common among people following a vegan diet, especially women. Iron is essential for maintaining healthy blood oxygen levels and energy production. Meat contains higher levels of iron, particularly heme iron, which is more easily absorbed by the body. A vegan diet may increase the risk of iron deficiency, which can lead to fatigue, dizziness, headaches, and other health issues.

Nutrient deficiencies

A vegan diet may also lead to deficiencies in other nutrients such as zinc, iodine, vitamin A, and omega-3 fatty acids. These nutrients are important for overall health and may indirectly impact the length of your cycle by affecting energy levels, hormone balance, and overall well-being.

PMS symptoms

Some studies suggest that a vegan diet may amplify PMS symptoms, including depression, panic attacks, insomnia, and irregular cycles. However, the connection between a vegan diet and PMS symptoms is not yet fully understood and may vary from person to person.

In conclusion, while a vegan diet may affect the length of your cycle in certain cases, it is important to note that individual factors such as overall diet quality, nutrient intake, and physical activity levels also play a significant role. It is always advisable to consult with a healthcare professional if you notice any significant changes in your cycle after adopting a vegan diet.

It can amplify your PMS symptoms

A vegan diet can amplify your PMS symptoms if it lacks certain nutrients. Here are some ways in which a vegan diet can lead to more intense PMS:

Lack of Complete Protein, Fat, and Cholesterol:

A vegan diet may not provide enough complete protein, fat, and cholesterol, which are essential for producing sex hormones. Protein is a crucial structural component of hormones, and a diet lacking sufficient protein can decrease levels of hormones such as prolactin, growth hormone, estrogen, thyroid hormones, and insulin. Additionally, a low-protein diet can stimulate a stress response, leading to increased body fat and fatty liver.

Presence of Anti-nutrients:

Vegan diets can be high in anti-nutrients like phytic acid and oxalic acid, commonly found in grains, beans, and soy. These substances bind to minerals in the gastrointestinal tract, preventing their proper absorption. This can lead to deficiencies in iron, zinc, calcium, and magnesium, which are essential for overall health and hormone regulation.

Vitamin B12 Deficiency:

Vitamin B12 deficiency is common among vegans as it is primarily obtained through animal-based foods or supplementation. B12 is crucial for maintaining energy levels, cognitive function, and healthy blood cells. A chronic B12 deficiency can have serious health consequences.

Inadequate Omega-3 Fatty Acids:

While vegetarian sources of omega-3 fatty acids exist, such as chia, flax, and walnuts, they are not as well-absorbed by the body. The body inefficiently converts the alpha-linolenic acid (ALA) found in these sources into the more beneficial omega-3 fatty acids DHA and EPA. Including direct sources of DHA and EPA in the diet can help improve overall health and potentially reduce PMS symptoms.

Lack of Vitamin D and Iodine:

Vitamin D and iodine are critical for healthy hormones, proper thyroid function, and regular periods. Vitamin D has been dubbed the "period vitamin" due to its impact on conditions like PCOS, PMS, and irregular periods. Iodine is essential for optimal thyroid function, similar to how gas is necessary for a car to run.

Insufficient Iron Intake:

Iron is more readily available and usable by the body from animal sources, such as liver and red meat. The iron in plant-based foods requires additional processing by the body for absorption. Vegans may need up to twice the recommended amount of iron compared to meat-eaters to meet their needs. Iron is essential for red blood cell production and oxygen transport in the body.

Deficiency in Vitamin A:

Beta-carotene, found in plant-based sources, is a precursor to vitamin A and needs to be converted into the usable form, retinol. However, evidence suggests that a significant portion of the population may have a genetic profile that reduces the conversion rate. Animal sources of vitamin A, such as liver and egg yolks, are necessary to avoid deficiency for these individuals. Vitamin A plays a vital role in fertility, promoting full-term pregnancy, and fetal development.

Zinc and Selenium Deficiency:

Zinc is predominantly found in oysters and meat, and vegans often struggle to obtain adequate amounts from plant-based sources. Nuts and seeds contain zinc but are often accompanied by phytic acid, which inhibits zinc absorption. Zinc deficiency can manifest as hair loss, frequent colds, and period problems. Selenium is also important for thyroid health and immune function, and adequate intake may help mitigate PMS symptoms.

You can become deficient in iron

Iron deficiency is a common issue for women, especially those who are menstruating. Iron is a mineral that helps your body create haemoglobin, a substance in red blood cells that carries oxygen around the body. When you don't have enough iron in your blood, it can lead to anaemia, which means your body doesn't have enough oxygen-rich blood flowing through it.

People with a menstrual cycle are more likely to have anaemia than those without one, regardless of their diet, because of blood loss during their period. Losing any amount of blood means losing red blood cells.

Studies suggest that people who follow plant-based diets could be more at risk of iron deficiency or low iron stores. However, this doesn't mean all vegetarians and vegans will experience iron deficiency.

The form of iron found in meat, heme iron, is more bioavailable, meaning it's easier for the body to absorb. Plants contain non-heme iron, a less bioavailable form of iron. Even though there's plenty of iron in plant-based foods, our bodies might not be able to use it as effectively, so people who rely on these foods may need to eat more to get enough.

The dietary recommendation for vegans is up to twice as high as the recommendation for meat-eaters. If you have a heavy menstrual cycle, it might be a good idea to include iron-rich foods in your diet, such as:

• Dark leafy greens like kale and spinach
• Beans and legumes, including kidney beans, navy beans, and black beans
• Lentils and chickpeas
• Iron-fortified cereals

Vitamin C helps your body absorb more of the iron in your food. If you are eating iron-rich plants, also eating vitamin C-rich foods like citrus fruits or bell peppers can aid iron absorption. You can also cook in a cast-iron skillet, as this adds small amounts of iron to food.

If you are worried about low iron, try to stop drinking tea, coffee, or milk with or after meals. Tannins (in tea) and calcium (in milk) inhibit iron from being absorbed.

If you think your iron levels might be low, consult your doctor. They may recommend iron supplements.

A vegan diet can make periods lighter and less painful

A vegan diet can be beneficial for women who experience painful and heavy periods. This is largely due to the absence of dairy and the presence of phytoestrogens in a vegan diet.

Dairy-free

Cow's dairy can make periods heavier and more painful because A1 casein can cause a mast cell and histamine response. Dairy and gluten (and sometimes eggs) can also worsen endometriosis.

Phytoestrogens

The phytoestrogens in grains, seeds, and legumes have a beneficial anti-estrogen effect. A moderate and healthy intake of phytoestrogens can make periods lighter and lengthen the follicular phase.

Nutrient deficiencies

A vegan diet can also cause nutrient deficiencies, which can affect periods. Nutrient deficiencies can cause low energy levels, which can be particularly prevalent at certain points in a woman's menstrual cycle.

Iron

Iron is one of the main concerns with a vegetarian diet. Meat is thought to be a more easily absorbed source of iron, meaning vegetarians and vegans need to put in a lot more effort to get what their body needs. Low blood iron levels can lead to anaemia, which can be a problem for women who tend to lose a lot of blood during their heavy menstrual cycles.

Weight and exercise

Research shows that people with a meat-free diet are more likely to have a lower body weight and be more physically active. A lower BMI and high amounts of exercise are known to reduce menstrual bleeding.

A vegan diet can cause irregular or heavy periods due to impaired ovulation and low progesterone

A vegan diet can be beneficial for some people, but it can also have some negative impacts on the menstrual cycle. While there is not enough conclusive research to show how plant-based diets impact the menstrual cycle, some studies suggest that a vegan diet can lead to irregular or heavy periods due to impaired ovulation and low progesterone.

Impaired ovulation and low progesterone

One of the main problems with a vegan diet is nutrient deficiency. A vegan diet may not provide adequate amounts of certain nutrients such as zinc, iodine, iron, vitamin A, and taurine. These nutrient deficiencies can impair ovulation and lead to irregular or heavy periods.

Iron deficiency

Iron deficiency is a common issue for people on a vegan diet, especially women. Meat contains higher levels of iron than plant-based foods, and the iron in meat is more easily absorbed by the body. Iron is essential for maintaining energy levels and preventing anaemia, which can be a problem for women with heavy menstrual bleeding.

PMS symptoms

In addition to irregular or heavy periods, a vegan diet may also amplify PMS symptoms. One study found that vegetarians had more premenstrual and menstrual symptoms and were more likely to have irregular cycles and heavier periods. This may be due to differences in iron levels or other nutrient deficiencies.

Weight and exercise

Research also suggests that people on a vegan diet are more likely to have a lower body weight and be more physically active. Extreme calorie restriction and excessive exercise can disrupt the menstrual cycle and even lead to amenorrhea (the cessation of the menstrual period).

Overall health

While a vegan diet can have some negative impacts on the menstrual cycle, it is important to note that it can also have many health benefits. A vegan diet has been linked to a decreased risk of obesity, diabetes, cancer, high cholesterol, and other health problems.
