Gas from legumes and greens distends the colon, keeps blood from reaching the brain and causes dizziness that is wrongly diagnosed as anaemia; the human body is not equipped to digest the hulls of fava beans, lentils or beans.

Original statement

انتفاخ القولون بتاعك اللي هيمنع الدم يوصل دماغك اللي يخليك بعد ما تقوم من ركوع وترفع راسك تدوخ تقوم من مكان اعدل مكان اعلى تدوخ وفي الاخر تقول لي انا عندي انيميا انيميه ايه انت عندك 4 جرام حديد في وزنك 100 كيلو 4 جرام حديد بس اللي انت عمال تقول نقص مخزون مش مخزون حديد الدم مش واصل دماغك عشان في رجليك الدم مش واصل دماغك عشان متحوش في بطنك بطنك الكبيره دايسه على مروحه هل انت جسمك مؤهل لهضم قشره الفول او الفول نفسه اصلا لا قشره العدس لا قشره الفاصوليا لا لا لا

Claimed mechanism

Colonic distension 'traps' blood in the abdomen.

Claimed health effect

Dizziness on standing, misdiagnosed 'anaemia'.

Population concerned

Everyone

Scientific assessment

Mostly false – Essential parts of the statement are not supported by the evidence or are strongly exaggerated.

Certainty of evidence: low – Further research is likely to change the assessment considerably.

1. What was claimed?

Gas causes dizziness that is misdiagnosed as anaemia; hulls are indigestible.

2. What is demonstrably correct?

Hull fibre is not digested by human enzymes and is partly fermented by colon bacteria, which produces gas; bloating is common after legumes.

3. What is wrong or exaggerated?

Indigestible fibre is not harmful in itself (see C-VEG-01). There is no evidence that intestinal gas reduces blood flow to the brain or explains laboratory-confirmed anaemia.

4. What remains unclear?

Not studied directly.

5. Which studies support it?

None.

6. Which studies contradict it?

Fibre meta-analyses (Reynolds 2019) and fermentation physiology (Koh 2016).

7. What applies to Germany and Europe?

Not specific.

8. What is known about Egypt?

Not specific.

9. What practical conclusion is appropriate?

Dizziness and fatigue should be investigated with a blood count; anaemia should not be dismissed as 'gas'.

Assessment details

Rationale for certainty of evidence

No study supports colonic gas as a cause of reduced brain perfusion or as a mimic of anaemia; anaemia is diagnosed by haemoglobin measurement, not by symptoms alone. The claim was not tested directly, hence low certainty.

Source quality

Single machine transcript; mechanistic statement without evidence.

Regional transferability

Not region-specific.

Individual exceptions

People with IBS experience bloating and pain from fermentable carbohydrates (see C-LEG-12).

Regional scope of the claim

general (biological/medical)

Last reviewed

25 October 2026 provisional

In plain language

Elawady said that gas from beans and vegetables presses on the abdomen, keeps blood from reaching the brain and causes dizziness that doctors mistake for anaemia. We found no evidence for this. Anaemia is diagnosed with a blood test, not from symptoms alone. Gas after beans is normal fermentation of fibre and is usually harmless.

Studies on this claim

Regional context

Germany / EU

Not specific.

Egypt

Not specific.

• Pesticide residues in fruit and vegetables on the EU/German market (incl. imports from Egypt)
• Pesticide residues in produce sold on the Egyptian domestic market
• Aflatoxins in groundnuts (peanuts)
• Nitrate in leafy vegetables
• Microbiological safety of fresh produce, herbs and spices
• G6PD deficiency and favism (fava beans)

What applies in my country?

General scientific assessment

Mostly false There is no evidence that intestinal gas mimics or explains anaemia.

The following areas of food safety are relevant to this statement:

• Pesticides and pesticide residues
• Contaminants (heavy metals, PFAS, PCBs, dioxins, nitrate)
• Mycotoxins (mould toxins)
• Pathogens (Salmonella, Campylobacter, etc.)

Fruit and vegetables · Legumes and nuts
