What is CSID?
CSID is an acronym which stands for congenital sucrase-isomaltase deficiency.
This is a genetically inherited condition in which your intestinal brush border is not making enough (or any) disaccharide enzymes that break down disaccharides (2-unit sugars such as sucrose and maltose), leading to a subsequent sucrose intolerance and/or starch intolerance.
CSID impacts approximately ~1% of the population worldwide and will usually show up in infancy; however, there are rare cases in which this gene variant can get activated later in life.
CSID vs. ASID
On that note, many people who are diagnosed with CSID as an adult actually have adult-onset acquired sucrase-isomaltase deficiency, or ASID.
Clinically, with ASID, we’re seeing the same symptoms caused by a similar brush border disaccharide enzyme deficiency; however, the cause of this enzyme deficiency is not genetic.
In cases of ASID, the brush border of your intestinal lining (where disaccharide enzymes are produced and released) has been damaged by inflammation from another underlying digestive disorder such as celiac disease, inflammatory bowel disease (IBD) or small intestinal bacterial overgrowth (SIBO).
(Read more about adult-onset sucrase-isomaltase deficiency here.)
CSID and ASID diet summary
Whether you have CSID or ASID, you’ll likely benefit from a customized variation of a sucrose intolerance diet (with or without starches, depending on your unique oral tolerance).
- A CSID-friendly diet consists of foods low in sucrose and possibly also foods low in maltose (which comes from starchy foods).
Note: If you’re dealing with ASID (vs. CSID), you may also potentially benefit from layering in some parameters from the low FODMAP diet, low sulfur/low histamine diet, gluten free diet or an anti-inflammatory, lower-roughage diet initially (depending on what is the underlying condition causing the ASID).
(It’s likely that not ALL of these CSID snack ideas will appeal to you, as this list is not customized to your food unique preferences and oral tolerance. Make sure you’re working with a CSID-informed gut health dietitian 1-1 for customization, as needed!)

Snack hacks & best practices
Aside from being CSID-friendly, I recommend leaning into snack foods that are also:
- Tasty
- Nutrient-dense
- Energetically sustaining
Another hack when it comes to strategic snacking is to pair a fruit, veggie, or other source of carbs with a healthy fat and/or protein-dominant food. (Think: cheese, nuts, etc.)
- This helps to slow down the rate at which the sugars from the snack will get absorbed into our blood and converted to energy, leaving us with a slower rise in blood sugar (and longer duration of sustained energy).
Check out the list of CSID snacks below for some inspiration and ideas to help nourish and sustain you, your loved one, or your clients in between meals!

Recap and final thoughts
Finding CSID-friendly snacks can be easy and simple when we get strategic. The secret sauce is pairing a low sucrose fruit/veggie (or starch, if tolerated) with a fat or protein-dominant low sucrose food.
Strategic snacking is the key to more balanced blood sugar levels and even-keeled energy throughout the day.
However, you can still occasionally snack on fruits or proteins by themselves.
Pick and choose whichever of the above featured low sucrose snacks resonate most for you.
Alternatively, you can try enzyme replacement therapy (i.e. Sucraid and/or Starchway) to eat snacks higher in sucrose/starch.
