We all know that home-cooked food is good for us. It's cleaner, safer and cheaper.

Dr. Kate Grimshaw of the University of Southampton gives us more reason to avoid store-bought food.

In her study, published last July 25 in the Journal of Allergy and Clinical Immunology, Dr. Grimshaw reviewed the food diaries for 1,140 babies from birth to their first birthdays.

Processed foods and instant meals

The data revealed that children with allergies were mostly fed processed foods like instant meals (hmmm, Lucky Me perhaps?), potato chips, pre-made sauces and bacon.

"The analysis showed that the infants who ate more fruits and vegetables and less commercially-produced baby foods and also less adult foods were the ones who did not develop an allergy by the time they were two," Grimshaw said.

There are some nutrients in the diet that strengthen the immune system whereas other components weaken it leading to allergies.

Avoid allergenic foods

It is best to avoid allergenic foods during the first year of a baby's life.

These include:

• all kinds of berries: strawberries, blueberries, blackberries

• dairy products: milk, ice cream, cheese ( that's why babies should be breastfed purely)

• food which contains wheat: wheat bread, wheat cereal

• chocolate

• cinnamon

• citrus fruits: orange, calamansi, dalandan, ponkan, suha

• food prepared with coconut and coconut milk

• corn

• egg whites
