  • Wild-caught fish
  • Grass-fed meats
  • Organic nuts and seeds
  • Unrefined coconut oil

Low-Quality Fats:

  • Refined vegetable oils
  • Processed meats
  • Hydrogenated oils
  • Deep-fried foods
  • Margarine and spreads

Fat Intake for Different Life Stages

  • Children (2-18 years): 25-35% of calories for growth and development
  • Adults (19-50 years): 20-35% of calories for maintenance
  • Older Adults (51+ years): 20-35% of calories with focus on omega-3s
  • Pregnancy: 20-35% of calories with increased omega-3s
  • Breastfeeding: 20-35% of calories for milk production
  • Athletes: 20-35% of calories based on training intensity
Pro Tip

Focus on fat quality over quantity. Choose whole food sources of healthy fats rather than processed oils. Aim for a balance of omega-3 and omega-6 fatty acids, with a ratio closer to 1:1 rather than the typical Western diet ratio of 1:15. Remember that fat is essential for health - don't fear it, but choose it wisely. Also, consider that your fat needs may vary seasonally (more in winter for warmth, less in summer) and with your menstrual cycle if you're a woman. Finally, fat intake should work in harmony with your protein and carbohydrate intake for optimal health and performance.
