Red meat: It is difficult to digest and often lies stagnant in your digestive tract. When this undigested food putrefies, it releases toxins and foul-smelling gases. This in turn is ejected as gas and sweat that stinks.
Processed and junk food: Any food that is too rich and difficult for your body to digest, any food that is processed and refined which contains too much sugar, white flour, hydrogenated oils and other processing agents, and food that is labelled as “junk” rot in your intestines and produces a foul odor in your breath and through your sweat.
Foods with pungent (strong-smelling) ingredients (used in large amounts): Garlic and other spices not only cause bad breath, they’re also responsible for body odour because they produce sulfurous gases when digested, which in turn are absorbed into the blood stsream and released through your lungs and pores.
Foods that are too fibrous: If you eat too much of foods that contain soluble fiber such as whole grains and beans, gases like hydrogen, carbon dioxide and methane are released when they get digested in your large intestine. When these exit your body by way of bottom gas.
A diet that is low in fiber: The opposite is also true – fiber is good for digestion and when your diet is poor in fiber, the residual food in your intestine causes the formation of gases like methane, leading to flatulence and belching.
Foods eaten in a hurry: Any food eaten too fast causes you to swallow too much air. When this is expelled from your body in a burp, you can bet you don’t smell like roses.
A diet that is low in carbohydrates: Carbs can be the villains of your weight loss program. When some people limit their carb intake, they automatically take in more proteins; this starts burning your body’s fat stores for energy, and this releases ketones into your bloodstream, which in turn makes your breath smell foul. This can be minimized be alkalizing i.e. eat more fresh green salads the chlorophyll in greens helps to neutralize nasty odours.
Dairy products: While they’re good for health in moderation, they tend to cause bad breath because they’re high in proteins that the bacteria in your stomach break down to create volatile sulfur compounds like hydrogen sulfide and methyl mercaptan which smell foul.
Drinking liquids through a straw: This applies to sodas and colas and other drinks that are fizzy as well – when you gulp down any drink through or straw or drink any liquid that has gas in it, you tend to burp because of the build up of gases in your stomach. And depending on what else is in your stomach, your breath and surroundings reek accordingly.
Chewing gum: You may chew gum for a variety of reasons – to get rid of a nicotine habit, to make your breath smell better (how ironic), or just to while away the time. But when you choose the sugar-free kind, your body does not completely digest the low calorie sweeteners like sorbitol, and when bacteria acts upon it in your intestine, it causes a buildup of gas which leads to burping and bottom burps.
Beans and legumes: Many kinds of beans cause gas because they contain a sugar called oligosaccharide, and this in turn causes flatulence and burping which makes you smell bad.
Foods rich in choline: Foods like egg and liver are rich in choline which is harder to digest; this causes gases to accumulate and generates a foul body odour.
Fried foods: They contain fats and oils that become rancid with the passage of time, and this in turn leads to poor digestion and excessive belching and flatulence.
Coffee: Coffee causes bad breath because the acidity and high sulfur content.
Alcohol: You know you reek the morning after a night out on the town, simply because you’ve had too much to drink. Alcohol makes your sweat and your breath smell really bad, so avoid it if you want to stay clean and fresh
