Sorry it’s so long… but hope to give some insight for you to take on board.
Bakerman, I think you need to knuckle down with regard to possible allergies/food intolerances if the medics have found nothing wrong with your gut. It’s up to you if you DIY or seek out specialists in that field.
I suffer with allergies to various things and also food intolerances - nothing life threatening, just inconvenient and unpleasant sometimes. Bloating, diarrhoea, rhinitis, sinusitis, migraines, facial swellings especially around the eyes, rashes over my body, mood changes… so much more. It’s 2021 now, so that’s 50yrs of playing with trying to control it all (or not at the moment). Sometimes I’m prepared to eat something that gives me problems just for the enjoyment of the food and to hell with the consequences. :-p
You’re in a far better position now, with the days of the internet for research purposes, than I ever was in the 70s when there wasn’t that facility. Also in those days alternative ingredients were very hard to come by whereas today it’s easy peasy. You have no excuses, so get on it if you can be bothered - it’s your decision.
A particular book that was a godsend for me is ‘The Allergy Diet and how to overcome your food intolerance’. Written by John Hunter, Consultant Physician and his team at the Gastroenterology Unit, Addenbrooke’s Hospital Cambridge. He’s a recognised authority on the subject of food allergy/intolerances and gut diseases. It’s dated 1984 and I know it’s been updated since then. It takes you through everything ie the exclusion diet, reintroducing foods and includes various recipes for those with intolerances to particular foods. What his updated version includes I’ve no idea, but it has to better and more informed than my copy from the 80s.
I’ve spotted too that he’s also written a book specifically for IBS. Goes without saying that nutritional needs are taken into account with these sorts of books, so no worries about starving your body of what it needs.
I’ve included a mishmash from that book here:
Treatment by diet seems to be the far best way to calm an irritable bowel. It’s not easy and time consuming. Problems vary from person to person and discovering the true culprits can be very time consuming and difficult.
Excluding food may be hard to start with but the test period is relatively short ie 2 weeks.
ANY food/foodstuffs can produce symptoms, although some do it more frequently than others ie Cereals (wheat, corn, oats, rye, barley, rice), Dairy, Eggs, Fish, Meat, Fruit, Veg, tea, coffee, nuts, chocolate, preservatives, yeast, sugar cane, sugar beet, alcohol, saccharin, honey. Then there’s food additives, preservatives, colourings - even some medicines.
Some foods contain salicylates which are natural chemicals similar to aspirin. Foods containing salicylates may also cause symptoms ie apples, bananas, blueberries, beer, cider, grapes, liquorice, peas, plums, prunes, red wine, rhubarb, strawberries.
An exclusion diet is usually for 2 weeks. THREE DAYS BEFORE STARTING THE DIET you must record all the symptoms you have had and when, to help judge the value of the diet later on.
You should find you steadily improve during the 2nd week. Any unexpected setbacks at this time will probably be caused by one of the foods eaten in the previous 24hrs.
If after 2 weeks your symptoms haven’t improved, it is likely food intolerance is not the cause of your problems.
Reintroducing foods:
How you begin reintroducing foods depends on which condition you have. For IBS it’s believed that ONE FOOD should be reintroduced every 2 DAYS.
There’s a set number of foods to reintroduce and the order of those foods. Some foods are made up of more than one ingredient for example in bread and wine. Test the ingredient concerned before trying the food ie test yeast before bread or wine otherwise if a reaction occurs, you will not know which ingredient caused it.
Flush out the chemicals in your system produced by the food reaction by drinking plenty of water. Some people find that adding a little bicarb of soda increases the effectiveness of this. Don’t take pills to relieve any symptoms as they confuses matters. Aspirin and paracetamol contain wheat and corn starches.
…
Basically, you need to do an Exclusion Diet for 2 weeks, then reintroduce foods over periods of time recording what you eat and how it affects you. It takes 2/3mths to find what might be affecting you.
Regarding probiotics, they’ve really helped my guts. Incidentally, stress and how it affects our bodies can also play a part in gut health.
Hope this is of some help 'cos it took a bloody long time to check my books and put it all down for you :-p
