People with smelly farts were actually caused by 〇〇
"I'm worried about the smell of farts recently..."
"I feel worse than before..."
It is a sign of deterioration of the intestinal environment.
The smell of farts will tell you honestly what is going on in the intestines. If it is odorless to slightly smelly, it is a sign of good bacteria dominating healthy intestines. Conversely, if it smells strong or sulfur, it is a sign that bad bacteria are dominating.
1. Growth of bad bacteria
When bad bacteria break down proteins, they produce smelly substances called indole and skatole. This is the true identity of "smelly farts."
Eating too much meat and eggs
When sulfur compounds contained in animal protein are decomposed in the intestine, sulfur odor (smell of rotten eggs) occurs. Be careful if you continue to eat meat.
3. Lack of good bacteria in the intestine
Good bacteria have the function of suppressing decay. If there are few good bacteria, the decay activity of bad bacteria will be uncontrolled and the smell will be strong.
4. Lack of dietary fiber
Good bacteria live on dietary fiber. If you eat a diet with less vegetables, mushrooms, and seaweed, good bacteria will not grow and the intestinal balance will be lost.
5. Chronic constipation
The longer the stool stays in the intestines, the more it decays. Not only odor but also harmful substances increase, which leads to rough skin and fatigue.
6. Processed food and additive-rich diet
It is known that some food additives disrupt the balance of intestinal bacteria. Diet habits centered on convenience stores and instant foods are burdensome to the intestines.
7. Excessive stress
Stress disrupts the peristaltic movement of the intestine, creating an environment where corruption is easy to proceed. The intestine and the brain are closely connected, and the mental state is directly connected to the intestine.
8. History of taking antibiotics
Antibiotics reduce not only bad bacteria but also good bacteria. There are surprisingly many cases where the intestinal environment is disturbed and does not recover after taking it.
9. Lack of sleep
Repair of the intestine is mainly done at night. If sleep is insufficient, the recovery of the intestine cannot keep up and the bacteria balance continues to be chronically lost.
10. Do not take fermented foods
Fermented foods such as yogurt, natto, miso, and nukazuke are direct sources of good bacteria. Just by incorporating one item into your daily diet, your intestinal environment will begin to change.
By the way, the normal range is the number of farts per day from 5 to 20 times. "Smell" is more important as a barometer of the intestinal environment than the number of times. If you start to worry about the smell, first review your diet.

「おならが臭い」「放屁が多い」って、地味にメンタルにきますよね。私も外出中に気になって、まず“回数”と“におい・お腹の張り”をセットで観察するようにしました。一般的に回数はある程度ブレがあるので、急に増えた/強烈に臭くなった/お腹がパンパンが続く…の方が要注意だと感じています。 私が実践してよかったのは、原因を1つに決めつけず「食事・便通・生活」を3日単位で整えること。特に放屁が多い日は、腸内で発酵や腐敗が進んでガスが増えていることが多いので、次の見直しが効きやすいです。 1) たんぱく質の量とタイミングを調整 肉・卵中心が続くと、腸内で分解される過程で硫黄臭や腐敗臭が出やすい印象でした。いきなりゼロにせず、夕食の肉量を少し減らして、魚・豆腐・納豆などに置き換えるだけでもラクになります。 2) 食物繊維は「水溶性」を意識 便秘気味でおならが臭いときは、野菜だけ増やすより、海藻・きのこ・オートミール・大麦・もち麦など“水溶性食物繊維”を足すと変化が出やすかったです。私はみそ汁にわかめ＋きのこ、主食をもち麦にするのが続けやすい定番。 3) 発酵食品は「毎日1品」から ヨーグルト、納豆、みそ、ぬか漬けなどを1日1品。ポイントは「食物繊維（エサ）」も一緒に入れること。発酵食品だけだと実感が弱い日がありました。 4) 便秘対策は“水分＋朝の習慣” 慢性的な便秘は臭いガスの温床になりやすいので、起床後にコップ1杯の水→朝食で軽く腸を動かす、を固定化。コーヒーで刺激を入れる人もいますが、胃腸が弱い人は無理しないのが大事です。 5) 加工食品が続いたら「リセット飯」を1日 コンビニ・インスタントが続いた翌日は、白米＋具だくさん味噌汁＋納豆＋果物、みたいにシンプルに戻すとお腹が落ち着きやすいです。 6) ストレスと睡眠も“腸の調味料” 忙しい週は放屁が多くなりがちでした。夜更かしをやめて睡眠を確保するだけで、腸の動きが整ってにおいが和らぐことがあります。 7) 受診の目安も知っておく 急に強い腹痛、発熱、血便、体重減少、下痢と便秘を繰り返す、特定の食品で毎回悪化、などがある場合は自己判断せず相談が安心です。 私の場合は「夕食の肉を控えめ＋水溶性食物繊維＋発酵食品1品」で、数日でにおいが軽くなりました。気になる人は、まず3日だけ“腸内環境を整えるセット”を試してみるのがおすすめです。
