Food Differences - SCD Vs FODMAPs

Hi everyone,

I'm doing a bit of research into the two, and wondering if anyone more knowledgeable would help me understand why these starchy foods are not allowed in SCD, but allowed in the FODMAP. What is it about the starch that permit them in FODMAP?

- Potatoes
- Rice
- Oats
- Corn

SCD assumes that ALL carbs are bad (well, all carb rich foods, all plants have some carbs)
It started in the 1950's from the work of a doctor that found removing carbs helped his patients and has gone on to become a widely used diet for many diseases/disorders.

This is a pretty good summary
What is the Specific Carbohydrate Diet?
“The main principle of the diet is that carbohydrates are classified by their chemical structure; they are monosaccharide, disaccharide, or polysaccharide. On the diet only monosaccharide carbohydrates are allowed to be eaten as all others require extra digestion steps to break the chemical bonds down to monosaccharide carbohydrates.

FODMAPS is a 'diet' designed to help you work out which foods you can digest well and is really only a (very helpful) short term thing. Different long chain carbohydrates break down and ferment with the help of different enzymes and are fed on by (to some degree) different bacteria.
By eliminating and reintroducing them you can work out which ones are tolerated and which are not,
The FODMAPS are not the only issue in foods (you may tolerate the carbohydrates in wheat but the proteins might be doing serious damage) so it is useful for identifying what gives you pain and gas and can help a lot with quality of life but it (FODMAPS) does not make any claims about being a cure/treatment/whatever.

FODMAP Diet: A Fad Diet or Helpful for Everyone?
““FODMAP.” It’s a medical acronym for Fermentable, Oligosaccharides, Disaccharides, Monosaccharides and Polyols.”
“F is for Fermentable– In this context, the fermentation of these carbohydrates occurs either in the small or large intestine. In many cases, this is normal and happens in healthy people. But in people affected by IBS the fermentation causes more pain than normal. The theory here is (in affected people) a reduction in all fermentation will improve the quality of patients’ lives.”

this is a great podcast and explains it well.......

All those links were from SCDLifestyle and their site is well worth looking around.
This next one sums it up pretty well – you are a snowflake, there isn't a one size fits all solution........

The Ultimate Digestive Troubleshooting Guide: What to Do When Diet Isn’t Helping Your Stomach Problems
“The diet that will work for you has no name.
You have a custom solution.You’re not going to be able to follow Breaking the Vicious Cycle and do SCD exactly as it’s laid out. You’re not going to be able to pick up a Paleo book and follow that blueprint and have it work for you. It’s just unrealistic. To get to the diet that works for you, you have to troubleshoot. You have to tweak. You have to be a health engineer!It’s a different mindset…I’m going to say this again: It is a different mindset.It is so important to know that. There is no pre-written script that says follow these exact steps and your specific digestive problems will go away… and that makes it tough – it isn’t coming to you pre-packaged.For example, some people don’t tolerate dairy. Others don’t tolerate legumes. Many don’t even tolerate fermented foods or food with high FODMAPs.
And that’s where people fail, that’s where the diet stops working and that’s where people lose hope. But if you keep your hope; if you change your mindset and keep your hope that YOU are a health engineer and YOU will figure this out, then you will succeed.”

I started with SCD, moved to paleo, then paleo with sweet potato and then PHD (Perfect Health Diet) and am pretty happy here (still playing around, planning to try lentils soon and eating mucho resistant starch), some people stay with SCD for years, some move around

This is worth reading (I think)

Sorry the last response was sooooo long.....
though about it and with less words.....
SCD eliminates all carb rich foods (All grains, sugar, potatoes ect)
Fodmaps (if done properly) eliminates and reintroduces to test for a reaction, all foods high in fermentablle sugars (including fructose, a monosacaride)

SO...SCD only cares about starchy carbs (because they see them as the root of the problem) and doesn't care about things like fructose and onions.
FODMAPS doesn't care about anything so long as you test for tolerance (tolerance being 'Is there an immediate digestive reaction?), and only of the ones most likely to be causing unwelcome fermentation.

You can do both at once,
an important (nay, vital) part of SCD is the intro diet [1] with a staged reintroduction of foods[2] to see if they are tolerated, so this is when the FODMAPS elimination diet also takes place, Testing FODMAPS tolerance takes place with the SCD reintroduction stages, just don't reintroduce the SCD 'illegals'....

From strict SCD (after bacterial action has been reduced) you can see what needs happening next - for me eliminating dairy (SCD yoghurt) was necessary, and adding in 'safe' carbs (rice, sweet potato) was OK/
Some people might need to be stricter (Paleo AIP with FODMAPS?) before they improve.......

A couple more peoples comparisons/thoughts, (and the first quote really capture the problem with FODMAPS)........
The gut and Paleo, SCD, GAPS, FODMAPs
Elimination diets are not as effective in my opinion, because some foods can create irregularity as late as 1-3 weeks after they’re consumed, making it impossible to know which food was the offending one.
