We need volunteers aged 30-70 y who eat two or more snacks per day to help us understand the health effects of consuming Almond nuts in place of usual snack products. The study will involve 6 visits (the 1st to check you meet criteria and explain the study) to King’s College London-Waterloo Campus/St Thomas’s hospital, small blood samples (13 teaspoons total), some body measurements, completing food diaries and for those eligible/willing an MRI and stool sample. You will be provided with almonds or muffin snacks to eat daily for 6 weeks. The total study duration is 8 weeks. Time and expenses will be reimbursed (£100 for time).
