Bad breath is one of those uncomfortable issues no one likes to discuss, yet almost everyone experiences it at some point. Most people assume that brushing twice a day, flossing, or using mouthwash should be enough to keep it away. While good oral hygiene is important, experts say that when bad breath persists even after brushing, the root cause might not be in your mouth at all.
In many cases, the gut plays a major role. When digestion slows down, food can stay longer in the stomach and ferment, creating gas and odor-causing compounds. These compounds can travel through the bloodstream and affect your breath — meaning the solution may lie deeper than toothpaste or mouthwash.
On Thursday, nutritionist Nmami Agarwal shared an informative video on Instagram highlighting this often-overlooked connection. “Brushing every day but still have bad breath? Maybe the problem is not your mouth, it is your gut,” she explained. In her post, the nutritionist broke down why it happens and how simple, everyday ingredients can naturally help reduce it.
1. Ginger
Nmami’s first recommendation was ginger. The spice contains gingerol, a compound that boosts saliva production and supports better gut movement. When digestion is sluggish, food remains in the system longer, increasing the chance of fermentation and unpleasant odors. Ginger helps the stomach empty on time, preventing these odours from forming.
2. Fennel Seeds
Next, she highlighted fennel seeds, which contain anethole — known for its antimicrobial properties. Nmami explained that fennel helps reduce gas in the gut and acts on sulfur-containing compounds, which are often responsible for strong, foul-smelling breath. This makes fennel an excellent after-meal digestive aid.
3. Peppermint
Peppermint, rich in menthol, offers natural antibacterial benefits. According to Nmami, peppermint works on bad-breath-causing bacteria in both the mouth and the digestive tract. The cool freshness it brings is also a sign of how it calms digestion and reduces odour from within.
4. Clove
Clove was the final ingredient on her list. Known for its powerful antiseptic and antibacterial properties, clove helps kill odour-causing bacteria. Nmami noted that when digestion functions well and inflammation stays under control, the mouth naturally stays fresher.
In her caption, the nutritionist added that bad breath is “sometimes your gut trying to tell you something.” She described the four ingredients — ginger, fennel seeds, peppermint, and clove — as offering a “mini spa session” for your gut. Her reminder to followers was simple: if something feels off, don’t always blame your toothpaste. Check your digestion, too.
