Spinach vs Swiss Chard

Vitamin C dramatically increases iron absorption

Pro tip: Squeeze lemon on your lentils or pair spinach with bell peppers

Magnesium is required to activate vitamin D

Pro tip: Pumpkin seeds + salmon = activation combo

High fiber can reduce zinc absorption — balance intake

Pro tip: Space high-fiber and zinc-rich meals apart if possible

Vitamin K directs calcium into bones, not arteries

Pro tip: Kale covers both — or pair leafy greens with dairy

Zinc helps transport vitamin A from the liver

Pro tip: Sweet potato + pumpkin seeds covers both nutrients

Selenium and vitamin E work together as antioxidants

Pro tip: Brazil nuts (selenium) + almonds (vitamin E) = antioxidant duo

Vitamins D and A balance each other for immune function

Pro tip: Salmon (D) + sweet potato (A) covers both fat-soluble vitamins

Copper is essential for iron metabolism and red blood cell formation

Pro tip: Liver and shellfish provide both — or pair cashews with lentils

High zinc intake can reduce copper absorption — balance both

Pro tip: Vary your protein sources between shellfish, nuts, and seeds

Vitamin C regenerates beta-carotene after it neutralizes free radicals

Pro tip: Bell peppers + sweet potatoes = powerful antioxidant combo

Fat-soluble lycopene absorbs dramatically better with dietary fat

Pro tip: Cook tomatoes with olive oil — heat + fat boosts lycopene availability 5x
