Vegetarianism

Vegetarians exclude meat, poultry, and seafood from their diets but may include dairy products and eggs. Key considerations for vegetarian diets include:

• Protein Sources: Plant-based proteins such as beans, lentils, tofu, tempeh, nuts, and seeds.
• Iron and B12: Ensure adequate intake through fortified cereals, leafy greens, and dairy (for lacto-vegetarians).
• Omega-3s: Include sources like flaxseeds, chia seeds, and walnuts for essential fatty acids.

Veganism

Vegans abstain from all animal products, including meat, dairy, eggs, and sometimes honey. Important aspects of vegan nutrition include:

• Protein Sources: Beans, lentils, tofu, tempeh, quinoa, and plant-based protein powders.
• Vitamin B12: Supplement or consume fortified foods like nutritional yeast and fortified plant milks.
• Calcium: Obtain from fortified plant milks, tofu, leafy greens (e.g., kale, broccoli).

Gluten-Free and Allergy-Friendly Choices

Gluten-Free Diet

A gluten-free diet excludes gluten, a protein found in wheat, barley, and rye. Options for gluten-free nutrition include:

• Grains: Quinoa, rice, corn, gluten-free oats, and certified gluten-free products.
• Proteins: Meats, fish, poultry, legumes, nuts, seeds, and tofu.
• Fruits and Vegetables: All fresh fruits and vegetables are naturally gluten-free.

Allergy-Friendly Choices

For individuals with food allergies (e.g., nuts, shellfish, dairy):

• Read Labels: Identify allergens and avoid cross-contamination in processed foods.
• Substitutions: Use alternatives like dairy-free milks (e.g., almond, soy), nut-free spreads (e.g., sunflower seed butter), and gluten-free grains.
• Cook at Home: Prepare meals from scratch to control ingredients and ensure safety.
