Your hormones, your gut, your plate: nutrition for women's hormonal health

When women come to see me about hormones, there's often an assumption that it all comes down to oestrogen — too much, too little, or being “out of balance.” Oestrogen is incredibly important, but it's only one piece of a much bigger hormonal picture.

Hormonal health is a finely interconnected network involving precursor hormones such as pregnenolone and DHEA, sex hormones including oestrogen, progesterone, and testosterone, as well as cortisol, insulin, thyroid hormones, and your body's stress response. Rather than acting independently, these hormones are in constant communication. When one hormone becomes imbalanced, it can influence many others, affecting everything from energy, metabolism, mood, sleep, weight, menstrual cycles, libido, and overall wellbeing.

Chronic stress plays a significant role in the interplay between the stress and reproductive hormone systems. When the body is under ongoing stress, activation of the HPA axis can increase cortisol production by the adrenal glands. Because cortisol and sex hormones are all derived from cholesterol and share aspects of the steroidogenic pathway, chronic stress can influence reproductive hormone production and regulation. Lower progesterone can contribute to symptoms such as irregular or heavy periods, PMS, anxiety, poor sleep, and relative oestrogen dominance.

Understanding these hormonal connections is key to identifying the root cause of symptoms rather than simply treating them in isolation, allowing for a more personalised and holistic approach to restoring hormonal balance.

During perimenopause, when progesterone naturally begins to decline before oestrogen, many women notice changes in their cycle, sleep, anxiety, resilience to stress and overall wellbeing. The good news: food and lifestyle choices influence many of these pathways every day.

Start with blood sugar

It's not always the most glamorous place to begin, but it might be one of the most powerful. When meals are heavy in refined carbohydrates and low in protein, healthy fats and fibre, blood sugar can rise quickly and then crash.

These fluctuations can contribute to energy dips, cravings, mood changes and increased stress on the body. They also require more insulin — a hormone that plays a central role in metabolism and can influence inflammation, fat storage and other hormonal pathways. Over time, repeated blood sugar spikes can lead to insulin resistance, where the body's cells become less responsive to insulin. To compensate, the pancreas produces even more insulin to keep blood glucose under control. Unfortunately, chronically elevated insulin doesn't just affect metabolism — it has far-reaching effects on hormonal health.

A simple but powerful habit: build most meals around protein, healthy fats and fibre, with quality carbohydrates included as part of the meal rather than the main focus.

Protein supports muscle, metabolism, satiety and stable energy, while fibre helps nourish the gut microbiome and supports healthy hormone metabolism. Healthy fats provide the building blocks for hormone production and help keep meals satisfying.

The gut–hormone connection

Here's where it gets fascinating. A specific community of gut bacteria — sometimes called the estrobolome — helps regulate how oestrogen is processed and recirculated in the body. After the liver packages oestrogen for removal, certain gut bacteria can, in effect, “reactivate” some of it so it's reabsorbed rather than excreted. When the gut is in good balance, this recycling runs smoothly. When it's disrupted, it may nudge oestrogen levels in either direction.

We're still early in understanding exactly how to influence this, so I hold it lightly — but it's a compelling reason that caring for your gut is part of caring for your hormones. A fibre-rich, diverse, plant-forward diet feeds a healthier gut community, and that's rarely a bad investment.

Perimenopause and menopause: a shift, not a decline

The years around menopause bring real change, and nutrition can make them noticeably more comfortable. I often talk about four pillars — what some clinicians shorten to PPFF: Phytoestrogens, Protein, healthy Fat and Fibre — set within a Mediterranean-style, plant-dominant way of eating.

A few priorities I emphasise in this season:

• Protein, consistently. Muscle becomes harder to maintain with age, so adequate protein (spread across the day) plus strength-building movement really matters.
• Calcium and vitamin D for bones. As oestrogen falls, bone health needs more attention; after 50, calcium needs rise. Think Greek yoghurt, chia seeds, tofu, fish with bones, and leafy greens — with optimising vitamin D to absorb it.
• Fibre for gut, heart and steadiness. Legumes and vegetables, nuts and seeds do quiet, important work here.
• Mind the alcohol. It can worsen hot flushes and disrupt sleep — both already under pressure in this stage.

Phytoestrogens: whole foods, not isolates

Phytoestrogens are plant compounds — found in soy, linseed (flaxseed) some legumes and vegetables — that can have mild oestrogen-like activity. The evidence is nuanced, and an important distinction comes from the women's-health experts at Jean Hailes: it's the whole foods (tofu, tempeh, edamame beans, soy milk made from whole beans, linseed) that are worth leaning on — not highly processed soy isolates or supplements, which can behave differently.

Beyond the plate

Food does a lot, but it works best in company. Sleep, stress, movement and alcohol all speak to your hormones too. You don't have to overhaul everything at once — small, steady changes in the right direction tend to outlast dramatic ones.
