Aktiv komparator: Traditional
Subjects in Study Arm 1 will undergo a screening process, and if randomized, will follow a traditional, site-based clinical trial model and undergo a baseline visit and 3 more in-person visits with the Principal Investigator (total of 4 visits). Subjects in each Study Arm will be randomized (2:1) to follow one of two dietary regimens during the study: the Combined Anti-Inflammatory Diet (CAID) or Control (standard nutritional advice). |
The CAID requires participants to modify their diet to include certain types of foods that may have anti-inflammatory properties.
Participants on the CAID will be required to abstain from red meat and alcoholic beverages.

|
Aktiv komparator: Remote
Subjects in Study Arm 2 will undergo a screening process, and if randomized, will undergo one Baseline visit at the local Gastroenterologist's office and 4 video visits with the Principal Investigator. A mobile nurse will visit subjects at a distant location (such as their home) to obtain blood samples at visits 1 and 4. Subjects in each Study Arm will be randomized (2:1) to follow one of two dietary regimens during the study: the Combined Anti-Inflammatory Diet (CAID) or Control (standard nutritional advice). |
The CAID requires participants to modify their diet to include certain types of foods that may have anti-inflammatory properties.
Participants on the CAID will be required to abstain from red meat and alcoholic beverages.
