…the Latin American food and cocktails at Seven Reasons—a mountain of black rice topped with prawns and pork cheeks, a salad in which the summery tang of tomatoes has been concentrated into cubes of jelly, a platter of hamachi tiradito whose pink and green splashes of salmon roe and jalapeño could hang in an art gallery—serve up jubilation as a remedy for pain and color as a cure for the blues.

“But what’s really intriguing is that we can now see how vitamin D might help the immune system fight cancer. We know when the Wnt/beta-catenin pathway is active in melanoma, it can dampen down the immune response causing fewer immune cells to reach the inside of the tumor, where they could potentially fight the cancer better.
