Foods & Research

Evidence-based nutrition information for informed food choices

Understanding Food Processing

Foods exist on a spectrum from minimally processed to ultra-processed. Understanding this can help inform your choices.

Minimally Processed Foods

Foods that are close to their natural state with minimal alteration:

  • Fresh fruits and vegetables
  • Whole grains (brown rice, oats, quinoa)
  • Eggs, fresh meat, fish
  • Plain yogurt, milk
  • Nuts and seeds

Ultra-Processed Foods

Foods with multiple ingredients, additives, and significant industrial processing:

  • Packaged snacks and chips
  • Sugary cereals
  • Frozen meals with many ingredients
  • Soft drinks and sweetened beverages
  • Processed meats with additives

Research suggests that diets high in ultra-processed foods may be associated with increased calorie intake. However, individual responses vary, and context matters.

Sugar & Sweeteners

Added sugars are found in many foods and beverages. Being aware of sources can help you make informed choices.

Common Sources of Added Sugar

  • Soft drinks and sweetened beverages
  • Candy and desserts
  • Flavored yogurts
  • Breakfast cereals
  • Sauces and condiments
  • Baked goods

Practical Tips

  • Read nutrition labels for added sugars
  • Choose water or unsweetened beverages
  • Opt for plain yogurt and add your own fruit
  • Be mindful of "healthy" products with high sugar
  • Enjoy treats in moderation without guilt

Protein & Satiety

Protein may help support feelings of fullness and muscle maintenance during weight management.

Animal Sources

Chicken, turkey, fish, eggs, Greek yogurt, cottage cheese

Plant Sources

Beans, lentils, tofu, tempeh, edamame, quinoa

Nuts & Seeds

Almonds, peanuts, chia seeds, hemp seeds, nut butters

Fiber & Digestive Health

Fiber supports digestive health and may help with satiety. Most people benefit from increasing fiber intake gradually.

High-Fiber Foods

  • Vegetables (especially leafy greens, broccoli, carrots)
  • Fruits (berries, apples, pears with skin)
  • Whole grains (oats, brown rice, whole wheat)
  • Legumes (beans, lentils, chickpeas)
  • Nuts and seeds

Increase fiber gradually and drink plenty of water to avoid digestive discomfort.

Liquid Calories

Beverages often don't provide the same satiety as solid foods, which can impact overall calorie intake.

Common Liquid Calorie Sources

  • Soft drinks and sweetened beverages (150-200 cal per can)
  • Fruit juices (120-180 cal per cup)
  • Specialty coffee drinks (200-500 cal)
  • Smoothies (200-600 cal depending on ingredients)
  • Alcoholic beverages (100-300+ cal per drink)

Lower-Calorie Alternatives

  • Water (plain or sparkling)
  • Unsweetened tea or coffee
  • Water with lemon or cucumber
  • Herbal teas
