Sickle Cell Disease (SCD) is a condition where blood cells form a crescent or 'sickle' shape instead of round. This disease is genetic, meaning it's passed down from parents. People with SCD may have more illnesses like strokes (when blood flow to the brain is blocked), constant pain, and heart issues. This study aims to learn how eating habits can help people with SCD feel better.

Participants will have a physical check-up and share their diet through interviews. They will also fill out surveys about their mood, stress, and diet. Blood and urine samples are needed, and fasting (not eating) for 8 hours is required before giving blood samples. The study lasts about 2 weeks.

• Participation involves physical exams, interviews, and surveys.
• Blood and urine samples are required with fasting beforehand.
• The study will last approximately 2 weeks.

Participants must be adults with SCD and willing to complete all procedures. They should speak English and not be pregnant or in the hospital for SCD during screening.
