Sense and Science
Eliminating foods that seem to make you sweat more or worsen your body odor is simply logical. However, many of the dietary recommendations for preventing or reducing underarm odor are not scientifically tested, so you should always consult your doctor before making any major dietary changes.
Underarm Odor and Diet
If the adage is true and you are what you eat, does that mean you smell like what you eat, too? Some studies say yes.
Eating certain foods such as garlic, onions, fish, curry, hot peppers and other spicy foods, and even alcohol can make your underarm odor smell worse. Research has also shown that eating red meat can also worsen underarm odor, whereas a diet without it might improve the smell [sources: WebMD].
There are also foods that researchers believe might help get rid of underarm odor. Drinking plenty of water and eating fruits, vegetables and whole grains should improve your overall health and metabolic function, which helps your body to work more efficiently. This can help lower your body's stress levels, which may decrease the amount that you sweat and help you avoid creating an environment that attracts odor-causing bacteria.
In addition, some alternative medicine practitioners say that adding a variety of vitamin-rich foods and herbs to your diet can also help to reduce underarm odor. For example, eating chlorophyll-rich foods such as kale and spinach is sometimes recommended as way to help neutralize other foods that cause underarm odor. Some nutritionists also recommend a detoxification diet, which includes vitamin-rich foods and herbs?, in addition to herbal and green teas, whole grain rice, vegetable juice and olive oil [source: Gottlieb].
In addition to changing your diet, you can also go right to the source of the problem and treat underarm odor where it starts. To learn what options are available for treating and preventing this condition, read on to the next section.
