Brain fog, hot flushes, night sweats… these are often the symptoms that dominate conversations around midlife women’s health. They are disruptive, visible and immediate. But one aspect that remains consistently overlooked is heart health. It matters in menopause because key physiological changes directly influence cardiovascular risk. A substantial body of evidence shows that lifestyle factors – including physical activity, smoking status and diet – have a profound impact on heart health. Crucially, these are modifiable risk factors. This article provides practical ways to support women to manage the cardiovascular changes that come with the menopause transition.
Cancer or heart disease. What do you think is the leading cause of death for women? Well, for both women and men, a heart disease is more likely to kill than all forms of cancer combined.1 Yes – you read that right. Historically, women’s cardiovascular risk has also been under-screened and undertreated. Women tend to develop heart disease at an older age than men, may present with different or less “classic” symptoms, and have been underrepresented in early cardiovascular research.2 The result is a persistent gap in prevention, recognition and management. For clinicians, menopause should not only prompt conversations about symptom relief – it should trigger a proactive reassessment of cardiovascular risk.

Why Menopause Matters for Heart Health 3,4,5,6,7
It has long been recognised that oestrogen provides a protective effect on cardiovascular health. However, only in recent years have we begun to fully appreciate the breadth of this protection – and the clinical implications of its loss during the menopause transition. Oestradiol (E2) plays a central role in regulating lipid metabolism, supporting endothelial function, reducing oxidative stress and modulating coagulation pathways. It helps maintain favourable cholesterol levels, limits fat accumulation within arterial walls and supports vascular flexibility.
As oestrogen levels decline during menopause, lipid profiles often deteriorate. Low-density lipoprotein (LDL) cholesterol and triglycerides increase, while high-density lipoprotein (HDL) cholesterol may decrease. These shifts promote lipid deposition within the arterial wall and accelerate atherosclerotic plaque formation, significantly elevating cardiovascular risk.
Interestingly, emerging evidence suggests that follicle-stimulating hormone (FSH) may independently contribute to cardiometabolic change. In a study of 278 perimenopausal women, researchers found that despite similar serum oestrogen levels, FSH, total cholesterol and LDL cholesterol were higher in perimenopausal women compared with their premenopausal counterparts. This suggests that cardiovascular risk during the menopause transition cannot be attributed solely to declining oestrogen.
Key physiological changes influencing heart health 6,7,8
Beyond lipid changes, menopause is also associated with a cluster of metabolic shifts that further compound cardiovascular risk. Glucose regulation becomes less efficient, increasing the likelihood of central weight gain, insulin resistance, type 2 diabetes and hypertension. Fat distribution shifts toward greater visceral adiposity, which is metabolically active and pro-inflammatory. Women may also become more sodium-sensitive during this period, contributing to fluid retention and elevated blood pressure. Collectively, these changes increase the risk of metabolic syndrome – itself a major driver of cardiovascular disease.
There is growing interest in the link between vasomotor symptoms and cardiovascular risk. Hot flushes and night sweats have been associated with higher blood pressure, adverse lipid profiles and other cardiometabolic risk markers. Similarly, depression during the menopause transition has been strongly linked to increased cardiovascular disease risk. These associations highlight that symptomatic burden may, in some women, serve as a clinical signal of underlying vascular vulnerability.
Reducing Cardiovascular Risk: The Role of Nutrition
The PREMIER Trial demonstrated that structured lifestyle interventions reduced estimated 10-year coronary heart disease risk by 12–14%, highlighting the tangible impact of dietary and behavioural change in clinical practice 9. For midlife women, particularly those transitioning through menopause, this represents a powerful opportunity for prevention.
Dietary patterns matter. A consistently poor diet – particularly one high in saturated fat and low in vegetables, fruit, wholegrains and oily fish – is associated with increased cardiovascular and stroke risk, although the precise mechanistic pathways continue to be refined.10,11,12
Robust evidence supports several dietary approaches in reducing cardiovascular risk, including the Mediterranean diet12, DASH diet13 and the Portfolio diet.14 While differing slightly in structure, these approaches share core principles:
- Emphasis on wholegrains, legumes, vegetables and fruit
- Inclusion of nuts, seeds and plant-based fats
- Regular intake of fibre-rich foods
- Reduction in saturated fat
- Limiting sugar-containing and highly processed foods
Importantly, these dietary patterns work because of their overall composition. Focusing on single nutrients in isolation – whether saturated fat, cholesterol or sugar – risks missing the broader, synergistic effect of dietary patterns combined with physical activity, sleep and stress management.
Diet and Cholesterol Management: The Science 5,10,11,12
Lipids, Fat Quality and Protein Substitution
Reducing saturated fat intake remains an important aspect of cardiovascular risk management. Evidence consistently shows that lowering saturated fat helps maintain normal blood cholesterol concentrations as part of a balanced dietary pattern.
Meta-analyses of controlled trials demonstrate that substituting animal-based proteins (from meat and dairy) with plant-based proteins (such as soya, legumes and nuts) significantly reduces total cholesterol, LDL cholesterol and non-HDL cholesterol. These lipid improvements are clinically meaningful, particularly in midlife women experiencing menopause-related shifts in lipid metabolism. The quality of fat appears more important than total fat intake alone. Replacing saturated fat with polyunsaturated fats (found in rapeseed oil, olive oil, nuts, seeds and oily fish) leads to greater LDL-C reduction than simply lowering dietary cholesterol intake.
Full-Fat vs Low-Fat Dairy
Dairy remains one of the major contributors of saturated fat in the UK diet.10 While some studies suggest certain dairy foods may have a smaller effect on blood cholesterol than others, compared with unsaturated fat sources, all dairy fats tend to raise LDL cholesterol. For this reason, cardiovascular guidelines continue to recommend replacing full-fat dairy products with low-fat or fortified plant-based alternatives alongside increasing unsaturated fat intake. However, emerging research suggests that the health effects of dairy may depend on the overall food matrix and type of dairy consumed (e.g., fermented versus non-fermented)12, highlighting that dietary guidelines that still emphasise low-fat dairy – may lag behind evolving evidence on the cardiometabolic impact of full-fat dairy foods.
Meat Substitution
Recent research exploring the replacement of meat with plant-based or mycoprotein-based alternatives is promising.17 A comprehensive systematic review and meta-analysis of 12 controlled trials found that replacing some or all meat with plant-based or mycoprotein-based substitutes lowered circulating cholesterol concentrations and improved cardiometabolic risk markers.18 In a four-week home-based intervention study involving 72 overweight adults, participants consuming 180g of mycoprotein daily experienced a 10% reduction in LDL cholesterol — equating to a 0.3 mmol/L decrease. For context, a 0.39 mmol/L reduction in LDL-C is associated with approximately a 25% lower lifetime risk of heart and circulatory disease.19 These findings are clinically relevant.
The proposed mechanism is thought to relate largely to soluble fibre content. Soluble fibre – including beta-glucan – reduces cholesterol absorption and enhances bile acid excretion. Fermentation by gut bacteria produces short-chain fatty acids (SCFAs), which may further support lipid regulation. There is also emerging interest in the potential interaction between fibre intake and the estrobolome, the subset of gut microbes involved in oestrogen metabolism – an area particularly relevant during menopause.
Dietary Cholesterol and Eggs
Eggs are rich in dietary cholesterol (approximately 186mg per egg). While very high cholesterol intakes can raise total and LDL cholesterol, current evidence suggests that replacing saturated fat with unsaturated fat produces greater LDL reductions than restricting dietary cholesterol alone.
Most guidelines therefore prioritise the overall dietary pattern rather than setting strict cholesterol targets. Within a heart-healthy dietary pattern, moderate egg consumption does not appear to increase LDL cholesterol for the majority of individuals. However, a subset of “hyper-responders” may experience greater rises in LDL-C and may benefit from limiting intake to approximately 2–4 eggs per week if clinically indicated.
From Evidence to Practice: Managing Cholesterol and Cardiovascular Risk in Menopause BOX OUT? 10,11
Key principles include:
| Strategy | Rationale & guidance |
| Increase Fibre Intake | Fibre is one of the most consistently supported dietary components for lowering LDL cholesterol and cardiovascular risk.
A meta-analysis of 67 controlled trials found that 3g of soluble fibre from oats (equivalent to around three 28g servings) reduced LDL-C by approximately 0.13 mmol/L within 3-7 weeks. Regular inclusion of oats, legumes, fruit, vegetables and wholegrains provides cumulative benefit.19 In practical terms, this could be achieved with a bowl of porridge made from around 40–60 g oats or a serving of oat-based cereal. Regular inclusion of oats alongside other soluble fibre–rich foods – such as beans, lentils, apples, berries, vegetables and wholegrains -can provide a cumulative cholesterol-lowering benefit when consumed consistently as part of the diet.20 |
| Improve Fat Quality | Total fat intake should remain within recommended ranges (generally <35% total energy intake), but the emphasis should be on fat type:
· Replace saturated fats with polyunsaturated fats · Encourage oily fish intake · Include plant-based omega-3 sources (walnuts, chia seeds, rapeseed oil) · Recommend a daily handful (≈40g) of unsalted nuts, which has been shown to reduce LDL cholesterol by ~0.12 mmol/L over 4–24 weeks As saturated fat intake decreases (≤30g/day for men; ≤20g/day for women), what replaces it matters. Replacement with refined carbohydrate does not confer the same benefit as replacement with unsaturated fat. |
| Moderate Free Sugar and Refined Carbohydrates | High free sugar intake adversely affects triglycerides, LDL-C and HDL-C, and contributes to cardiometabolic risk. Supporting reductions in refined carbohydrates can improve lipid profiles and metabolic health. |
| Individualise Dairy Guidance | While debate continues around full-fat versus low-fat dairy, current cardiovascular guidance supports choosing low-fat options and increasing unsaturated fat sources. For women with elevated LDL-C during menopause, this shift can be clinically meaningful. |
| Contextualise Egg Intake | For most individuals, eggs can be included within a balanced dietary pattern (for example, 1–2 per day in clinical practice). If lipid response suggests hyper-responsiveness, reducing to 2-4 per week may be appropriate. |
| Supplements: A Food-First Approach | While supplements containing plant stanols or sterols are available, they are not permitted to carry percentage cholesterol-lowering claims in the same way as certain fortified foods (such as dairy products containing added plant stanols/sterols). The evidence base for plant stanol/sterol-enriched foods supports modest LDL-C reductions when consumed at effective doses, but these benefits are best considered as adjunctive to — not replacements for — broader dietary pattern change. |
Endothelial Function and Vascular Health: The Science 21,22
The endothelium – a single layer of cells lining the interior of blood vessels – plays a central role in cardiovascular health, yet it is often overlooked. One of its key functions is the production of nitric oxide (NO), a molecule that promotes vasodilation, inhibits platelet aggregation and reduces vascular inflammation. Healthy endothelial function supports flexible, responsive arteries, whereas endothelial dysfunction is an early step in atherosclerosis and a strong predictor of future cardiovascular events.
Blood pressure is closely linked to endothelial health. Persistently elevated blood pressure increases shear stress on the vascular wall, impairing nitric oxide production and promoting oxidative stress. Over time, this damages the endothelial lining and accelerates arterial stiffening.
Lifestyle factors significantly influence endothelial integrity. Excess body weight, smoking, physical inactivity, insufficient sleep and chronic stress all contribute to vascular dysfunction. Dietary drivers include high salt intake, excess free sugars and high alcohol consumption. Oxidative stress is a key underlying mechanism. When reactive oxygen species exceed antioxidant defences, nitric oxide availability declines and vasodilation is impaired. Diets rich in antioxidant-containing foods – particularly fruits, vegetables, legumes, wholegrains and nuts – help counteract oxidative stress and support endothelial function.
Nitrate-Rich Foods and Nitric Oxide
Dietary nitrates have gained attention for their vascular benefits. Found mainly in vegetables such as beetroot, spinach, rocket and other leafy greens, nitrates are converted via the nitrate–nitrite–nitric oxide pathway into nitric oxide, enhancing vasodilation and supporting endothelial function.
Clinical studies show that regular intake of nitrate-rich vegetables can lower blood pressure and improve vascular stiffness. These benefits are seen when nitrates are consumed from whole vegetables rather than processed meats, where they coexist with harmful compounds.
For menopausal women — who may experience rising blood pressure and reduced vascular flexibility — supporting nitric oxide production through diet is a simple, evidence-informed strategy.
From Evidence to Practice: Protecting Vascular Endothelial Cells
| Strategy | Rationale & guidance |
| Prioritise Blood Pressure Control | Encourage patients to:
· Maintain a healthy weight · Stop smoking · Increase physical activity · Improve sleep quality · Moderate alcohol intake · Reduce salt consumption Even modest reductions in systolic blood pressure can meaningfully lower cardiovascular risk. |
| Increase Antioxidant-Rich Foods | Advise a daily intake of diverse, colourful plant foods to provide polyphenols, vitamin C, carotenoids and flavonoids. These compounds help reduce oxidative stress and preserve nitric oxide availability.
Practical strategies include: · “Eat the rainbow” approach · Adding berries to breakfast · Including vegetables at both lunch and dinner · Swapping refined snacks for nuts and fruit |
| Incorporate Nitrate-Rich Vegetables | Encourage regular inclusion of beetroot, rocket, spinach, watercress and Swiss chard. These can be added to salads, smoothies, soups or roasted dishes. Consistency matters more than high-dose short-term intake. |
Lifestyle Matters 3,5,6
Diet is central to cardiovascular prevention, but no single nutrient works in isolation. Cardiovascular disease is multifactorial, influenced by smoking, alcohol intake, physical inactivity, stress, sleep and obesity — particularly visceral adiposity. These factors affect endothelial function, lipid metabolism, inflammation and blood pressure.
Hormonal status is also relevant. When initiated in appropriate candidates within the therapeutic window, hormone replacement therapy (HRT) may reduce coronary heart disease risk and all-cause mortality in younger postmenopausal women. However, careful cardiovascular risk assessment is essential, and HRT should not be prescribed solely for CVD prevention.
