Changing ones diet can have dramatic results for those women who suffer from bacterial vaginosis, especially those unfortunate enough to experience reoccurring cases of the condition. Studies carried out have shown that there is in fact a strong link between the amount of dietary fat intake and the likelihood that a woman will get bacterial vaginosis. It has also been proved than the severity and frequency a woman suffers from the condition is also related to the fat intake in her diet.

Research has shown that saturated fats can reduce the immune response in the vagina and change the vaginal acidity so it favours the bad bacteria instead of the good, which is required to protect from certain infections. Such saturated fats can be found in foods like butter, full fat milk, red meat, cheese and pastries. So by cutting down on these food types can help the treatment of BV. These fatty foods can be replaced with monounsaturated fats, found in olive oil, canola and tea seed oil, as they are known to have a small effect on causing bacterial vaginosis. In addition, polyunsaturated fats, found in fish oils, sunflower seeds and bananas, have proved to have no effect whatsoever on producing the imbalance in vaginal bacteria.

Other dietary tactics that can be used to help ward off bacterial vaginosis include increasing the intake of vitamin E. Vitamin E is known for its antioxidising properties that fortify the immune system. Other vitamins than can help prevent infection are vitamins A and C along with iron and zinc. Vitamin E can be found in foods such as almonds, sunflower seeds, kiwi and in greens such as spinach and broccoli.
