Episode description
- People who ate the most ultraprocessed foods had a 41% higher risk of developing lung cancer compared with those who ate the least
- The increased risk was seen in both smokers and nonsmokers, showing that diet alone influences lung cancer development
- Processed foods alter nutrient absorption, strip away protective compounds, and add toxic byproducts that fuel inflammation and immune dysfunction
- Harmful chemicals from packaging and high-heat cooking further raise cancer risk and weaken your body's defenses
- Choosing whole, unprocessed foods and cutting linoleic acid in vegetable oils down to 2 grams or less daily is one of the most effective ways to protect your lungs
