Health Benefits of Eggs

- Rich in Vitamins and Minerals: Eggs provide significant amounts of several vitamins and minerals, including B vitamins, vitamin D, and selenium, which support various bodily functions from energy metabolism to immune health.
- Heart Health: Recent studies suggest that moderate egg consumption does not significantly impact heart disease risk in healthy individuals. The presence of nutrients like omega-3 fatty acids and antioxidants (lutein and zeaxanthin) in eggs may even promote heart health by reducing inflammation.
- Eye Health: The antioxidants lutein and zeaxanthin found in egg yolks can help protect against age-related macular degeneration and cataracts.
- Weight Management: Eggs can be satiating due to their high protein content, which may help with appetite control and weight management when included in a balanced diet.

- Allergies: Some individuals may have allergies to egg proteins, which can lead to allergic reactions.
- Cooking Methods: The way eggs are prepared can affect their health benefits. Boiling or poaching eggs is healthier than frying them in oil or butter.
