Final answer:
Of the options provided, milk is not commonly associated with lowering the risk of RA or easing its symptoms, while fish, cooked vegetables, and olive oil have anti-inflammatory properties that may be beneficial.
Step-by-step explanation:
Rheumatoid arthritis (RA) is a chronic autoimmune condition without a known cure, primarily affecting the synovial joints leading to symptoms like joint inflammation and pain. Among the foods that have been shown to help lower the risk of RA or ease its symptoms are fish, cooked vegetables, and olive oil, all known for their anti-inflammatory properties. However, milk is not commonly associated with reducing the risk of RA or easing its symptoms and, in some cases, dairy products may exacerbate symptoms for certain individuals. It's important to consider individual dietary needs and responses when managing RA.
