Regarding lecithin and phytoestrogenic foods?


Hello, I am a college entrance exam candidate.
Recently, I was diagnosed with fibrocystic breast changes in both breasts, and my doctor advised me to avoid foods that contain estrogen.
However, I found that many foods, such as soybeans, yam, and apples, may contain phytoestrogens.
I would like to know which foods I can eat and which ones I should avoid.
Additionally, I follow a lacto-vegetarian diet and have been taking soy lecithin as a nutritional supplement, but my doctor said that it contains plant-based estrogens and advised me to stop consuming it.
Since I am currently preparing for my college entrance exams and need to use a lot of brain power, I want to supplement with lecithin.
Can I drink soy milk, or should I purchase lecithin supplements derived from egg yolk? Are there any other alternatives that can help enhance brain function and memory?

Dear Xiaoya,
Hello! Soybeans contain isoflavones, which function similarly to female estrogen and are therefore referred to as phytoestrogens.
Their most unique characteristic is that they can act as both "antagonists" and "weak agonists" of female hormones.
The antagonistic effect refers to the ability of isoflavones to compete with estrogen for binding sites on estrogen receptors in healthy, young women with normal hormone secretion.
This competition can help prevent excessive estrogen from binding to its receptors, thereby reducing the risk of breast cancer and cervical cancer.

On the other hand, the agonistic effect refers to the role of soy isoflavones in postmenopausal women, whose hormone levels gradually decrease.
In this case, soy isoflavones can supplement estrogen activity and alleviate symptoms caused by declining estrogen levels.

Yam is related to hormones because diosgenin can serve as a precursor for hormone production in the body, but it does not directly produce female hormones, so there is no need for concern.
Although many natural foods contain compounds similar to estrogen, their concentrations are very low, and moderate intake is generally acceptable.

You are currently in a growth and development stage and need sufficient protein intake.
Since you are a lacto-ovo vegetarian and under exam stress, it is important to drink milk daily, consume an egg every 1-2 days, and include appropriate amounts of legumes and soy products in each meal.
You may supplement with a multivitamin, but I do not recommend taking extracts that contain phytoestrogens.
Wishing you a Happy New Year and success in your exams!
Sincerely,
Dietitian Shih Kuei-Mei

When it comes to achieving hormonal balance and supporting brain health, it's essential to understand the types of foods that can either help or hinder your goals. As a student preparing for university exams, maintaining optimal cognitive function is crucial, especially considering your recent diagnosis of fibrocystic breast changes. Here’s a comprehensive guide on what to embrace and avoid in your diet.


Foods to Embrace
1. Whole Grains: Foods like quinoa, brown rice, and oats are excellent sources of complex carbohydrates, which provide a steady release of energy. They also contain fiber, which is beneficial for digestive health.

2. Fruits and Vegetables: Aim for a variety of colorful fruits and vegetables. Berries, leafy greens, and cruciferous vegetables (like broccoli and cauliflower) are rich in antioxidants and vitamins that support brain health and hormonal balance. For example, berries are known for their neuroprotective properties.

3. Healthy Fats: Incorporate sources of omega-3 fatty acids, such as flaxseeds, chia seeds, and walnuts. These fats are essential for brain health and can help reduce inflammation in the body. Avocados are another great source of healthy fats that can support cognitive function.

4. Lean Proteins: Since you follow a lacto-vegetarian diet, focus on dairy products like yogurt and cheese, as well as eggs, which are excellent sources of protein and contain choline, a nutrient that supports brain health.

5. Herbs and Spices: Turmeric, ginger, and cinnamon not only add flavor but also have anti-inflammatory properties that can benefit overall health.


Foods to Avoid
1. Processed Foods: Foods high in refined sugars and unhealthy fats can lead to inflammation and hormonal imbalances. Avoid snacks like chips, cookies, and sugary drinks.

2. Soy Products: Given your doctor's advice to avoid foods high in phytoestrogens, you should limit or eliminate soy products, including soy milk and tofu, as they can mimic estrogen in the body.

3. High-Sugar Foods: Excessive sugar can lead to spikes in insulin and cortisol levels, which can negatively impact hormonal balance and cognitive function.

4. Caffeine and Alcohol: Both can disrupt hormonal balance and affect sleep quality, which is crucial for brain health, especially during exam preparation.


Alternatives for Brain Health
Since you are looking for alternatives to lecithin for brain support, consider the following options:
- Egg Yolk: If you consume eggs, the yolk is a rich source of choline, which is vital for memory and cognitive function.


- Fish Oil Supplements: If you are open to supplements, omega-3 fatty acids from fish oil can be beneficial for brain health. If you prefer plant-based options, consider algae oil supplements.

- Nuts and Seeds: Incorporating a variety of nuts and seeds can provide essential fatty acids and antioxidants that support brain health.

- Dark Chocolate: In moderation, dark chocolate (with a high cocoa content) can improve blood flow to the brain and enhance cognitive function.


Conclusion
In summary, focus on a balanced diet rich in whole foods, healthy fats, and lean proteins while avoiding processed foods and those high in phytoestrogens. If you are concerned about your dietary choices, especially regarding lecithin and soy products, consult with a registered dietitian or nutritionist who can provide personalized advice based on your health needs and dietary preferences. Remember, maintaining a balanced diet not only supports hormonal health but also enhances cognitive function, which is vital during your exam preparations. Good luck with your studies!
