Food allergies and sensitivities seem to be more and more common. There are theories that blame lack of diversity in our diet, low levels and poor diversity of good bacteria in our gut (microbiome) or GMOs, pesticides, heavy metals and other toxins. I suspect that there is an impact of all these factors, a cocktail of stresses that interacts with our own individual make up.
A good first step is to identify any foods you react to and avoid them for a time while you build your system back up to a robustness that can handle anything. Just avoiding foods long-term is not advisable as the list tends to increase, leading to a very limited diet that might not provide all the nutrition you need. Also when you do inevitably eat a problem food your system will likely produce a huge reaction.
So, while your body is having some respite:
Build up your microbiome. Your diverse range of good bacteria actually helps you digest your food and absorb the nutrients from it! Look after it by eating as wide a variety of colourful and nutrient packed plants as you are able. Include some resistant starch from beans, lentils, cooked and cooled rice and potatoes. Prebiotics are the plant fibre that feed our beneficial probiotic bacteria, include wholegrains, root vegetables, under-ripe bananas, asparagus, artichokes, the onion family, the crucifer family and apples. Add in more good bacteria. Probiotic capsules are popular but there are 1000's of strains needed for optimal health, greater diversity can be found in fermented foods and in eating the skins of raw organic fruits or salads. Just being in different natural environments exposes you to a wide range of beneficial microbes -breathing in that fresh sea air, walking through woodland, digging the earth while gardening, or literally smelling the roses!
Limit toxins. Eat organic where you can, filter water, avoid plastic bottles, aluminium pans and heating food in foil. Include fresh herbs in your meals, coriander and parsley help remove metals from the gut.
Eat diversely. Avoid building up an intolerance to something else, grains are common -vary it. Include some quinoa and oats, there are pastas now based on lentils and brown rice. Roast or mash different root vegetables or squash. Butterbean mash with olive oil, lemon and parsley is so much more interesting than white potatoes.
Have some Health Kinesiology sessions. This can help remove any over-reactions your body has created, relieving allergy symptoms and boost digestive function so that you are able to tolerate more foods. Kinesiology also helps with setting up a schedule for reintroducing foods at the best time and identifying any further problem foods (or other substances). We work towards a robust body that embraces all of life!
