If you’re a woman over 40, you may notice the impact of declining estrogen on your physical and mental health. Symptoms such as increased appetite, weight gain, and gut-related issues can significantly affect your well-being, coupled with fatigue, mood changes, impaired cognition, and vasomotor symptoms (hot flashes, night sweats). Fortunately, dietary adjustments can alleviate these symptoms. One such approach is the bean diet, a plant-based dietary plan that can support gut health, hormonal balance, and stable energy levels.
This article explores the 7-day bean diet for women, delving into the reasons why beans should be a staple food, how to balance macronutrients, tips for preventing bloating, and how to adapt the diet for women over 40.
Why Beans Should Be a Staple Food, Especially After 40
Beans are rich in essential vitamins and minerals, including protein and fiber, making them excellent for weight loss and gut health. Here’s why beans deserve a prominent place on your plate:
Nutrient Density, Fiber, and Affordable Protein
Beans provide a wealth of dietary fiber and protein. For instance, 100 grams of black beans contain 47.9 g of carbohydrates, 15.2 g of fiber, and 21.6 g of protein, contributing significantly to your daily intake of these essential nutrients. They are also a rich source of potassium, manganese, iron, magnesium, and B vitamins, while being low in fat and sodium. These nutritional benefits can lead to lower cholesterol, triglycerides, blood pressure, heart rate, and inflammation, while improving gut health and insulin sensitivity.
How Beans Support Hormonal Health
The nutrient density of beans can positively influence hormone health. A 2013 study investigated the effects of brown beans on appetite-regulating hormones, revealing that they lower blood glucose and insulin responses while suppressing the hunger hormone ghrelin.

The Gut-Bean Connection: SCFAs and Estrogen Detox
Beans have a unique connection with the gut, enhancing digestive health. They contain short-chain fatty acids (SCFAs), which are primary metabolites produced in the colon through bacterial fermentation of fiber and resistant starch. SCFAs play a crucial role in gastrointestinal physiology, immune function, metabolism, and the regulation of the central nervous system (CNS).
Furthermore, beans can aid in estrogen detoxification. Estrogen, a steroid hormone linked to female reproductive organs and sexual characteristics, affects the breast, uterus, vagina, bone, and cardiovascular system. However, excessive estrogen levels can increase the risk of cancer, disrupt the reproductive process, contribute to polycystic ovary syndrome, and affect mood and cognitive function. Fiber binds to estrogen in the gut, facilitating its elimination through stool, thus supporting hormone balance and reducing the risk of these issues.
Are Beans Safe to Eat Daily?
While beans offer numerous health benefits, it's important to address concerns about their daily consumption. Here, we discuss misconceptions, preparation methods, and when to adjust or temporarily halt bean consumption.
Myths About Lectins and Antinutrients
Beans contain lectins and antinutrients, which are often perceived as harmful. However, this isn't entirely accurate. Antinutrients, including lectins, are proteins found in plants that have both positive and negative effects on nutrition. They can protect against certain cancers and boost the immune system, but, like lectins, they can also reduce nutrient absorption and cause digestive issues like nausea, vomiting, and diarrhea if consumed raw. Fortunately, these negative effects can be mitigated through preparation methods such as overnight soaking, boiling, steaming, and canning.
Preparing Beans for Better Digestion
Proper preparation is crucial for enhancing bean digestion. This involves soaking, boiling, or thorough cooking. Here’s how to prepare fresh beans to improve digestion:

When to Adjust or Pause Consumption
The high fiber content of beans is beneficial, but it can also lead to digestive discomfort and bloating in some individuals. If you're new to eating beans, introduce them gradually to your diet to minimize bloating. If you have digestive issues like Irritable Bowel Syndrome or Crohn’s disease and experience adverse effects, consider reducing your bean intake.

Balancing Macronutrients on a Bean-Heavy Diet
Balancing macronutrients on a bean-heavy diet may seem challenging, but it can be quite manageable. Here’s how to adjust your nutrition to meet your daily requirements and create a balanced diet.
Combining Beans with Healthy Fats
Beans are high in protein, carbohydrates, and fiber, making them ideal for pairing with healthy fats. The standard macronutrient ratio is 45-65% carbohydrates, 10-35% protein, and 20-35% fat. Since beans cover significant portions of the carbohydrate and protein categories, the remaining 20-35% of your daily calorie intake should come from healthy fats.
Foods rich in healthy fats that complement a bean diet include:

When to Add Grains or Greens
Whole grains and greens are excellent additions to a bean diet. While grains also contain complex carbohydrates and dietary fiber, they can enhance meals by adding volume, flavor, texture, and essential nutrients. Consider adding grains during the cooking process or combining them with beans at the end. Greens, on the other hand, are low in calories but rich in vitamins and minerals, making them versatile for any stage of food preparation. Spinach, for example, can be added raw to salads or cooked with other ingredients.
Protein Considerations for Active Women
Incorporating beans into your meals makes it easier to meet your protein targets. The recommended daily protein intake is 0.8 grams per kilogram of body weight, but this increases to 1.4-1.6 g/kg for those looking to optimize their body for training. For a woman weighing 70 kg, 0.8 g/kg equals 56 grams of protein. A typical serving of beans (approximately ½ cup or 75 g) contains about 16.5 grams of protein, meaning that even one serving can provide over 25% of the daily protein requirement. Even for active women needing 98g of protein daily, beans can significantly contribute to this goal, especially when combined with high-protein foods like fish, poultry, nuts, and seeds.
Tips to Avoid Bloating on a High-Bean Diet
Bloating can be a common issue when increasing bean consumption. Here are some tips to minimize bloating:
Start Slowly and Rotate Legumes
Gradually introduce beans into your diet and rotate them regularly. Begin by reducing the serving size from ½ cup to ¼ cup for the first few days. If bloating subsides, gradually increase the amount while monitoring your body's response. Additionally, switch between different types of beans and ensure they are thoroughly cooked to improve digestion.
Use Digestive Spices Like Cumin or Ginger
Spices like cumin and ginger can aid in bean digestion. A 2013 study showed that cumin extract could reduce bloating and other irritable bowel symptoms. Ginger also has positive effects on digestion, helping to reduce bloating. Adding these spices to beans, combined with thorough cooking and chewing, can alleviate symptoms and make the bean diet more sustainable.
Hydration and Movement to Assist Digestion
Drinking water with meals and exercising afterward can help reduce bloating. Sufficient water intake softens stools, reducing constipation, which is often associated with bloating. Movement after meals stimulates gastrointestinal (GI) motility, which facilitates the movement of food and liquids through the GI tract, improving digestion and reducing bloating.
Adjusting the Bean Diet for Midlife Needs
The bean diet can be tailored to meet the specific needs of women in midlife. Here’s how to modify your meal composition to address blood sugar, menopause, thyroid issues, and polycystic ovary syndrome (PCOS).
Menopause and Blood Sugar
Women over 40 often face challenges related to menopause. Symptoms such as vasomotor symptoms (hot flashes, night sweats), fatigue, increased appetite, weight gain, and mood changes can impact health and quality of life. Beans contain fiber, protein, and carbohydrates, which help stabilize blood sugar and appetite. They also contain phytoestrogens, plant-derived compounds similar to estrogen, which can alleviate menopause symptoms.
To further adjust the diet, focus on a balanced intake of lean protein, complex carbohydrates, and healthy fats to reduce the severity of menopause symptoms and stabilize blood sugar, ultimately improving quality of life.
Thyroid-Friendly Bean Pairings
The thyroid is a vital endocrine organ responsible for regulating metabolism, growth, and the function of the heart, brain, digestive system, skin, and hair. Beans contain essential nutrients for thyroid health, including selenium, zinc, iron, magnesium, and vitamins A and B12. Black beans, kidney beans, lima beans, and chickpeas are excellent sources of these nutrients and can support thyroid health.
Plant-Based Meal Planning for PCOS
PCOS is a common metabolic disorder characterized by irregular menstruation, high androgen levels, and small cysts on the ovaries, often caused by poor lifestyle choices, diet, and genetic predisposition. Women with PCOS may experience abnormal insulin sensitivity, obesity, acne, hair loss, mood swings, and infertility, and are at higher risk for type 2 diabetes, cardiovascular disease, and cancer.
Beans are highly beneficial for women with PCOS due to their high fiber and protein content. Fiber improves insulin sensitivity and blood sugar control, while both fiber and protein enhance satiety, aiding in weight loss. Weight loss of just 5% can significantly improve PCOS symptoms by reducing the impact of obesity and inflammation, which in turn reduces the risk of negative health outcomes, including type 2 diabetes.
Additional Tips for a Successful Bean Diet
- Incorporate a Variety of Beans: Include different types of beans like chickpeas, lentils, black beans, and soybeans to diversify nutrient intake and prevent palate fatigue.
- Combine with Colorful Produce: Aim for 5 to 10 servings of fruits and vegetables daily to create colorful, nutrient-rich meals.
- Limit Processed Foods and Meat: Reduce consumption of ultra-processed foods and limit meat intake, focusing on plant-based proteins like tofu and beans.
- Cook at Home: Preparing meals at home more frequently allows for better control over ingredients and portion sizes, promoting healthier eating habits.
- Practice Mindful Eating: Pay attention to portion sizes and eat until you're 80 percent full to avoid overeating.
- Stay Hydrated: Drink plenty of water throughout the day, as it is the preferred beverage in blue zones. Coffee, green tea, and herbal teas can also be included.
The Bean Protocol: A More Flexible Approach
The bean diet is not a rigid diet but rather a flexible way of incorporating beans into your daily eating habits. Unlike restrictive diets, the bean-focused approach encourages including legumes in your diet, which is both cost-effective and beneficial for your health.
Potential Benefits of a Bean-Rich Diet
- Increased Muscle Mass: Individuals who regularly work out may notice faster muscle gains when they start eating more beans.
- Reduced Calorie Intake: Legumes are complex carbs that can help reduce overall calorie intake.
- Rich in Folate and Antioxidants: Beans are packed with folate and antioxidants, contributing to overall health.
- Reduced Risk of Heart Disease: Regular consumption of beans can lower the risk of heart disease.
