What is the best exercise?  I was often asked.  My most often simple answer is:  The exercise you are willing to do, and do it regularly.

What is the best diet?   You bet I can't answer this question the same way I answer the 1st question.

Diet is a whole lot more complex.  So, I approach this question from the opposite angle, what are the bad diet we should really avoid, avoid from young?

 

 

LCD or Low-Carbo Diet is a commonly promoted diet, that is popular.  Yes, it is my opinion that LCD is one of the diet we should really avoid, especially if the carbo is replaced with animal protein AKA meat.  

 

This is a technical, medical research paper write up. In simple common language, it means, LCD in young adults put them at higher risk of getting heart disease in their middle age, and also progression of blockage is higher. Therefore, those who use LCD, esp LCD with non plant protein for weight management should take special care to prevent heart disease/heart attack.  

 

Do low-fat, low-protein diets show LOWER cancer risk?

✔ YES — in observational studies, low-fat + low-protein (especially low-animal protein) diets correlate with the lowest cancer incidence.

Examples:

1. Rural China Diet (The China Study)

  • Protein <10% of calories

  • Fat <10–15%

  • 70–80% carbs from whole plant foods

  • Cancer incidence among lowest ever recorded

  • Animal protein strongly correlated with cancer mortality across regions

2. Traditional Okinawan Diet

  • Protein ~9%

  • Fat ~6%

  • Carbs ~80% (mostly sweet potato)

  • Lowest cancer rates globally (both incidence and mortality)

3. Adventist Health Studies (AHS-1, AHS-2)

Vegans and near-vegans (low protein, low fat):

  • Significantly reduced risk of all cancers

  • Especially GI, breast, prostate cancers


SUMMARY

How do fat and protein correlate with cancer risk?

Protein

  • High animal protein → increases cancer risk

  • High plant protein → neutral or lowers risk

  • Low total protein (especially animal) → lowest risk

Fat

  • High saturated fat → increases risk

  • High unsaturated fat (olive oil, nuts) → protective or neutral

  • Very low fat → lowest observed cancer rates in long-lived populations

 

If we think in term of avoiding diseases, the above ChatGPT analysis does imply that avoid LCD, moving toward simple Old time Kampung style diet is better, makan kangkung, type. 😁

Carcinogen Classification. Stuff to avoid

  August 22, 2025   We are afraid of dying slowly, ie Dementia, and Cancers.  If there is a way to prevent these, would you be interested?  Many would go for getting to the root causes, and manage exposure to these.  I want to write about cancer causing agents 1st. International Agency for Research on Cancer (IARC) has evaluated >1000 agents and classified them into classes according to likelihood (strength of evidence) as below:       Here is a short YouTube video explaining this table  https://www.youtube.com/watch?v=WP60nNXqNOo   This time, FOR HEALTH, I bring up about WHAT TO AVOID. to stay in good health (the negatives).  Next week, I should talk about what to GET INTO OUR BODY, or DO to stay in good health (the positives). GROUP 1 means "confirmed" cancer causing agents. Here is the link to the list  https://en.wikipedia.org/wiki/IARC_group_1  as of 2024. Here are some we are familiar with: Viruses - HIV, HPV, He...

ANTIBIOTIC

  November 21, 2025   Antibiotic was a great discovery about 100 years ago. It saved many lives over the past century, likely someone closed to you have been protected by it, or even you, and me.     However, situation becomes more complex when it is overused.  Here is why: Antimicrobial Resistance (AMR) happens when germs—like bacteria, viruses, fungi, and parasites—stop responding to the medicines used to kill them. When this happens, antibiotics and other treatments no longer work well. This makes infections harder or sometimes impossible to treat, which can lead to more people getting sick, more severe illness, and more deaths. World AMR Awareness Week (WAAW) is a worldwide event held every year from 18 to 24 November . Its goal is to help people understand what AMR is and why it is a serious problem, and to encourage countries and communities to take action. It is one of the official health campaigns of the World Health Organization (WHO). The th...
