【健康】千萬不要這樣吃，癌細胞越長越大！名醫曝3招防癌秘辛：消滅腫瘤！ft.精準醫療名醫 曾嶔元｜下班經濟學439

Summary

In this insightful discussion, Dr. Tseng Chih-yuan shares his journey of overcoming cancer through precision medicine and genetic testing. He emphasizes the importance of personalized treatment based on individual genetic profiles and outlines dietary strategies to reduce cancer recurrence, such as lowering insulin levels through fasting and optimizing nutrient intake. The conversation highlights the role of lifestyle choices, including exercise and the consumption of healthy fats, in cancer prevention. Dr. Tseng also addresses common misconceptions about cancer genetics, advocating for a proactive approach to health management.

Takeaways

• 😀 Precision medicine allows for personalized treatment based on individual genetic makeup.
• 😀 Insulin plays a significant role in cancer cell growth; reducing its stimulation can help prevent cancer.
• 😀 Intermittent fasting can lower cancer occurrence by reducing insulin spikes and creating a harsh environment for cancer cells.
• 😀 Genetics accounts for only 5-10% of cancer risk, while environmental factors and luck contribute significantly.
• 😀 A diet rich in healthy fats (60%) and limited carbohydrates (20%) may help in cancer prevention.
• 😀 Regular exercise (at least 150 minutes a week) can reduce the risk of several types of cancer.
• 😀 Vitamin C has potential cancer-fighting properties, but dosage and method of intake are crucial for effectiveness.
• 😀 Maintaining a healthy gut microbiome may enhance immune response against cancer cells.
• 😀 The quality of fats consumed matters; saturated fats from natural sources can be beneficial.
• 😀 Understanding the role of specific bacteria in oral health can be crucial in preventing cancer recurrence.

Q & A

What is precision medicine?

Precision medicine, also known as personalized medicine, refers to tailored treatment approaches based on individual genetic profiles and conditions, aiming for more effective healthcare outcomes.

How can diet influence cancer cell growth?

Diet can impact cancer cell growth by affecting insulin levels; higher carbohydrate intake stimulates insulin secretion, which can promote cancer cell proliferation.

What role does intermittent fasting play in cancer prevention?

Intermittent fasting can create a hostile environment for cancer cells, potentially reducing their growth by decreasing insulin levels and calorie intake, thereby lowering the risk of cancer development.

How does genetic testing differ from standard health check-ups?

Genetic testing identifies specific gene mutations associated with cancer, while standard health check-ups generally monitor overall health indicators, such as tumor markers, which can yield false positives or negatives.

What is the significance of calorie restriction in studies on longevity?

Studies have shown that calorie restriction in animal models can lead to increased lifespan and reduced incidence of diseases, including cancer, highlighting its potential benefits for health.

Why is cholesterol often misunderstood in relation to health?

Cholesterol is essential for the body, and while it's categorized as 'good' (HDL) and 'bad' (LDL), the harmful effects are primarily linked to oxidized LDL, not cholesterol itself.

What dietary fats are recommended for cancer prevention?

Healthy fats such as monounsaturated fats from olive oil and saturated fats from sources like butter and coconut oil are recommended for their potential health benefits.

Can fasting actually kill cancer cells?

Fasting doesn't directly kill cancer cells but can create adverse conditions for their growth, helping the immune system to target and eliminate them more effectively.

What types of foods should be avoided for cancer prevention?

Foods high in simple carbohydrates and sugars should be limited, as they can stimulate insulin production and potentially promote cancer cell growth.

How can maintaining oral hygiene impact cancer risk?

Good oral hygiene can help reduce harmful bacteria that may weaken the immune system's ability to fight cancer cells, thus lowering the risk of cancer recurrence.
