    Even foods in the same 'pyramid' group affect gut bacteria differently

    Spinach and carrots are both known rich in vitamin A, fiber and potassium but that doesn't mean they have the same effect on our gut microbiomes, a new small study finds  We tend to think of food in terms of the broad categories of the food pyramid: fruits, vegetables, meats, dairy and so on But researchers say how specific strains of gut microbes are affected by the foods we eat can actually vary significantly from fruit to fruit or vegetable to vegetable  Leafy greens like kale and spinach can promote one bacterial species, but carrots and celery could promote another – even though they all fall under the same category in the food pyramid  The team, from the University of Minnesota, says its study shows that its not enough to look at the nutrition labels and that future food-based interventions hoping to regulate gut bacteria may need to be tailored to the individual person +1 <img id="i-5a219ef5edb54920" src="https://idailymail
