Food Combining Rules

Adding vitamin C to plant-based iron sources can increase iron absorption by up to 6 times. This is especially important if you eat a plant-based diet or are prone to iron deficiency.

Your body cannot absorb vitamins A, D, E, and K without fat present in the meal. Always include healthy fats when eating colorful vegetables.

Turmeric on its own is poorly absorbed. Adding black pepper makes the beneficial compounds 20 times more available to your body.

Lycopene, the powerful antioxidant that makes tomatoes red, is much better absorbed when tomatoes are cooked and eaten with fat.

Yogurt and other fermented foods contain beneficial bacteria. Adding fiber-rich foods "feeds" these bacteria, helping them thrive in your gut.

Eating lentils or beans with rice or potatoes significantly reduces the blood sugar spike. The low-GI food "anchors" the meal.

After a workout, eating both protein and carbs together gives a small but measurable boost to recovery compared to either alone.

Taking calcium supplements or eating dairy with iron-rich foods reduces how much iron you absorb. If iron is important for you, separate these by a few hours.

Drinking tea or coffee with meals can reduce iron absorption by 50-90%. If iron status is a concern, drink these between meals.

Whole grains and legumes contain phytates that bind to minerals. This isn't a big concern in a balanced diet, but you can reduce phytates by soaking, sprouting, or fermenting.

Spinach is often promoted as a calcium source, but the oxalates in spinach bind most of the calcium. Don't rely on high-oxalate greens for calcium.

"Don't eat protein and starch together"

Your body digests them simultaneously without issue.

"Fruit ferments in your stomach if eaten with other foods"

Your stomach is too acidic for fermentation. This can't happen.

"Food combining helps you lose weight"

The only clinical trial showed zero benefit over normal eating.

"Acidic and alkaline foods cancel each other out"

Your body tightly controls pH. Food doesn't change it.

"Fruit should only be eaten on an empty stomach"

Flexible timing is fine, but fruit before meals may help satiety.
