food sensitivities
allergy or intolerance
There are no allergens in olli organic baby foods. That's why they are so wonderful to introduce as first foods when you can't make your own organic varieties at home. As your baby progresses with his weaning however, he will be introduced to a greater variety of foods from different sources. So it helps to know what foods you need to be more aware of and what type of reactions to look out for.

You'll find that there is a great deal of controversy over food allergies. True food allergies (type I allergies) are actually quite rare but are more common in infancy and up to 5 years. A food allergy, where the body's defense system rejects a particular foreign protein, is an immediate immune reaction and can be extremely dangerous, if not fatal.

The foods that have most commonly been found to cause a type 1 reaction are nuts, seeds, egg, fish and soya products. However, any and every food has the potential to have an allergenic effect.

The second type of food allergy is called a food intolerance or food sensitivity. A type II reaction, and does not necessarily involve any immune response at all. These types of food reactions can be difficult to isolate but being aware of the common symptoms is a good place to start.
food intolerances can build up over time

The most common culprits are wheat (gluten) and dairy products, which are often eaten several times a day from a very early age. It is also worth noting that exposure to pesticides can cause a range of ill effects, from relatively mild symptoms such as headaches, fatigue and nausea, to more serious effects such as cancer and neurological disorders.
common allergenic foods
wheat
Start introducing after 12 months. Other gluten grains (oats, rye, barley) can be introduced at around 9 to 12 months.
eggs
The egg yolk can be introduced to babies older than 9 months and the complete egg only from about 12 months and older.
cow's milk
Start introducing between 12 to 24 months.
soya
Start with fermented soya products at around the 9 to12 month mark, make sure that soya is not GM.
shellfish
Wait until the 24+ month mark to introduced shellfish.
fish
Not as common as allergies to mollusk and shellfish and can be introduced earlier between 6 to 9 months.
peanuts
This allergy can be life threatening. Leave these until after 24 months. A lot of the problems with peanuts come from the high aflotoxin levels found on them. Organic peanuts should have much lower levels as they are grown in healthier soils.
nuts and seeds
A person with a peanut allergy doesn't necessarily have a nut or seed allergy, and visa versa. Tree nuts and seeds can be introduced with caution at around 12 months.
