3. Popular Q&A: 5 questions that netizens are most concerned about
1.“Can soy milk induce breast cancer?”
The latest research shows that daily intake of 10-20g of soy isoflavones (about 1-2 cups of soy milk) may reduce the risk, but hormone receptor-positive patients need to consult a doctor.
2."Does vitamin D help?"
Women with serum vitamin D levels ≥40ng/ml have a 67% risk reduction (PLOS One 2023 study), and it is recommended to sunbathe or supplement cod liver oil.
3.“Does cooking style have a big impact?”
Deep-frying can produce acrylamide and other carcinogens. It is recommended to steam, cool or stir-fry at low temperature.
4.“Do superfoods like turmeric work?”
Curcumin has shown anti-cancer activity in the laboratory, but the human body absorption rate is low. It is recommended to use black pepper (piperine) to enhance the effect.
5.“Do men need prevention?”
Male breast cancer accounts for 1%. Obesity and alcohol abuse are the main risk factors. You also need to pay attention to the above dietary recommendations.
4. 7-day anti-inflammatory diet plan (example)
| breakfast | lunch | dinner |
|---|---|---|
| Oats + blueberries + flax seeds | Brown rice + steamed salmon + broccoli | Tofu miso soup + cold seaweed shreds |
| Whole wheat bread + avocado | Quinoa Salad + Grilled Chicken Breast + Tomatoes | Stir-fried vegetables with mushrooms + pumpkin porridge |
Conclusion:Dietary prevention should be combined with regular exercise (150 minutes of moderate intensity per week) and regular screening. The American Cancer Society recommends that women ages 20 to 40 have breast exams every three years and women over age 40 every year. Starting today, use every bite of food to build a healthy defense line for yourself!
