One portion covers a large share of your weekly omega-3 and delivers vitamin D — a nutrient almost no other food supplies in useful amounts.
Baked at 180°C. That loses less omega-3 than a long, hard sear over high heat.

Heat the oven to 180°C.
Slice the garlic and leave it for ten minutes.
Season the salmon with salt and pepper and rub it with olive oil.
Cut the broccoli into bite-sized florets and add them to the same tray.
Lay the garlic slices over the salmon and bake for 12–15 minutes.
Squeeze over the lemon and serve.
Omega-3 is vulnerable to heat and oxygen. A 180°C oven loses less than direct high heat, and the antioxidants in lemon and olive oil slow the oxidation of those fats during cooking. Twelve minutes is enough for the broccoli — do not leave it longer.

Vegetables
Moderate evidenceThe evidence for garlic points to a modest drop in blood pressure and cholesterol. The trick is to crush it and wait ten minutes before it hits the heat.

Early researchBroccoli's key compound, sulforaphane, only forms when the vegetable is cut or chewed. One cooking choice changes how much survives.
