FODMAP Load Calculator

Sum key FODMAP group grams to estimate potential symptom load.

FODMAP Load Calculator

Estimate the combined intake of key FODMAP carbohydrate groups

Understanding the Inputs

Know what each FODMAP value represents before calculation

Fructans (g): Total grams of fructans from foods like wheat, onions, garlic, and inulin during the meal/day.
Lactose (g): Grams of lactose from dairy sources; lactose-free products can be logged as 0.
Polyols (g): Sugar alcohols such as sorbitol and mannitol found in stone fruits and certain sweeteners.
Excess Fructose (g): Fructose intake beyond glucose balance, often from apples, honey, or high-fructose sweeteners.
Galactans (g): Fermentable galacto-oligosaccharides from beans, lentils, and some cruciferous vegetables.

Complete Guide: Navigating FODMAPs

A staged low-FODMAP approach helps identify trigger carbohydrates while maintaining nutritional adequacy. Combine elimination, systematic reintroduction, and personalized maintenance to broaden food variety without aggravating symptoms.

Work with a healthcare professional for medical conditions, ensure adequate calories, and integrate stress management, sleep, and movement to complement dietary changes.

Frequently Asked Questions

Detailed, SEO-oriented answers

What are FODMAPs?

FODMAPs are fermentable carbohydrates (fructans, lactose, polyols, excess fructose, galactans) that can trigger gas, bloating, and GI symptoms in sensitive individuals, especially those with IBS.

How do I use this calculator?

Enter approximate grams of each FODMAP group consumed in a meal or day. The calculator sums the load to help you identify whether your intake is low, moderate, or high.

What counts as a low FODMAP load?

Although tolerance varies, many IBS protocols target less than 10 g total per meal and under 20 g per day during elimination phases. Use personal tolerance and dietitian guidance for precise targets.

How accurate are food FODMAP values?

Values can vary by ripeness, processing, and portion size. Use reliable databases (Monash University, accredited dietitians) and keep a symptom journal to tailor the plan.

Can I stay on a low-FODMAP diet forever?

Long-term strict FODMAP restriction may reduce beneficial gut bacteria. The diet is typically implemented as elimination, reintroduction, then personalization to include as many foods as tolerated.

Do FODMAPs affect everyone?

No. Many people digest FODMAPs without issue. They primarily trigger symptoms in individuals with IBS, SIBO, or other functional gut disorders.

How do I reintroduce FODMAPs?

Test one group at a time in gradually increasing portions over 3–4 days while monitoring symptoms. Work with a dietitian for structure and to avoid unnecessary restrictions.

Can I combine FODMAP groups in one meal?

Yes, but cumulative load matters. Even tolerated foods can provoke symptoms if multiple FODMAP groups are consumed in large amounts simultaneously.

What other factors influence symptoms?

Stress, sleep, hormones, and gut microbiome health all affect symptom severity. Pair diet adjustments with lifestyle and stress-management strategies.

Should I take supplements?

Digestive enzymes, probiotics, or prebiotics may help some people. Introduce supplements cautiously and preferably under professional guidance, especially during elimination phases.
