India has a rich culinary tradition, yet iron deficiency, vitamin D deficiency, and poor calcium absorption remain common. A key reason is the reliance on supplements, expecting them to fill nutritional gaps instead of focusing on bioavailability, which is the body’s ability to absorb and utilise nutrients when foods are paired strategically, because some vitamins and minerals enhance each other’s uptake while others need components like fat or vitamin C to cross intestinal barriers. By combining foods wisely, you can boost absorption naturally and make everyday meals more effective for long-term health.

Vitamin C + Iron (ideal for vegetarians and vegans)

Pairing: Lemon with spinach; amla with poha; tomatoes with rajma or chole.

Why it works: Indian diets rely heavily on non-heme iron from dals, spinach, millets, and legumes. Vitamin C converts non-heme iron into better absorbed ferrous form that the intestine can take up more efficiently.

What it does:
Boosts iron absorption
Helps prevent anaemia, especially in women
Supports immune function

Best time to have: Morning meals or lunch when digestive capacity is strong.

Helpful hack: Always squeeze lemon on palak, chole, rajma, methi thepla, or sprouts.

Healthy Fats + Fat-Soluble Vitamins (A, D, E & K)

Pairing: Ghee or mustard oil with leafy vegetables; peanuts with carrot sticks; avocado with paratha.

Why it works: Our meal preparations often use ghee, groundnut oil, or sesame oil, all excellent carriers for fat-soluble vitamins. Without fat, vitamins A, D, E, and K pass through the gut without absorption.

What it does:
Improves vision and skin health (vitamin A)
Supports bone strength (vitamin D & K)
Provides antioxidant protection (vitamin E)

Best time to have: Lunch or dinner are the ideal time for fat digestion.

Helpful hack: Add a teaspoon of ghee to dal-sabzi for better nutrient uptake.

Calcium + Vitamin D (critical for bone health in India)

Pairing: Curd with vitamin D supplements/fortified milk, paneer with egg or ragi porridge.

Why it works: Vitamin D facilitates calcium’s movement from the intestine into the bloodstream. Yet India has high rates of vitamin D deficiency despite ample sunlight, so large amounts of dietary calcium often go to waste because the body simply cannot absorb it well. This makes the pairing even more critical.

What it does:
Strengthens bones and teeth
Supports muscle function
May boost immunity

Best time to have: Short sunlight exposure between 8:30 AM and 10:30 AM when vitamin D synthesis is most effective.

Helpful hack: Ragi dosa + tadka curd/buttermilk = winning bone-strengthening combo.

Lycopene + Healthy Fats

Pairing: Tomato curry with mustard oil; okra with peanut oil; tomato soup with ghee tadka.

Why it works: Lycopene: an antioxidant present in tomatoes and watermelon is fat-soluble. It becomes more bioavailable when cooked with oil.

What it does:
Supports heart health
Reduces oxidative stress
Protects skin from ageing

Helpful hack: Tomatoes taste better and absorb better when cooked in oil, especially mustard or groundnut.
