There is a gap in this category between what is claimed on the landing page and what is published on the nutrition page, and it runs in a consistent direction.
Territory Foods markets its menu under the heading "No gluten, no dairy and no inflammation", and publishes calories, fat, carbohydrates and protein — but not fiber, not sodium, not sugar. MealPro states that its meals reduce inflammation, describes its plan as the only clinically studied anti-inflammatory meal plan on the market, and lists conditions it says the plan is recommended for, including multiple sclerosis, osteoarthritis and autoimmune disease. Those are claims the companies make. They are recorded here as claims, not endorsed as findings, and nothing in the published panels can confirm or refute them.
Then there is the disagreement, which I did not expect and find genuinely clarifying.
MealPro's anti-inflammatory plan excludes tomato, lemon and garlic on the grounds that they may be inflammatory, along with chili, pepper, red meat and dairy. Meanwhile Sunbasket, Green Chef and HelloFresh all market the Mediterranean pattern as the anti-inflammatory option — and the Mediterranean pattern is built on tomato, lemon and garlic.
Two services can both sell you an anti-inflammatory plan and disagree about whether a tomato belongs in it. The category does not have a shared definition of its own product, which is the single best reason to define the pattern from an outside source before comparing anything, and to read the panel instead of the plan name.
HelloFresh is worth one more line, because it is the neatest example of marketing running ahead of the product. It operates a dedicated Mediterranean Diet Meal Plan Delivery page. The plans it actually offers at signup are Ready Made Meals, Meat and Veggies, Veggie, Family Friendly, Fit and Wholesome, Quick and Easy, and Pescatarian. There is no Mediterranean plan. There are Mediterranean-inspired recipes you can pick off the general menu, which is a reasonable thing to sell and a different thing from what the page name promises.
If supplements are the other half of this question for you, we graded those by evidence tier in Best Anti-Inflammatory Supplements: Ranked by Clinical Evidence.
