Episode notes
Rising Meat Demand Threatens Sustainability
- Global meat demand could rise ~50% by 2050, making conventional livestock unsustainable.
- Tuck Seng Wong argues we must develop nutritious, affordable and environmentally responsible alternative proteins.
Protein Shortages Often Reflect Diet Imbalance
- Around one billion people currently lack enough protein, often due to carbohydrate-heavy diets.
- Julie Gray highlights that malnutrition often stems from dietary imbalance, not absolute lack of protein globally.
Alternative Protein Is A Broad Umbrella Term
- 'Alternative protein' has no legal definition and spans plants, insects, cultivated meat, biomass and precision fermentation.
- Dr Kang Lan Tee explains the term covers diverse products beyond traditional meat and fish.
