Reducing your intake of carbs, as the keto diet does, goes hand-in-hand with reducing intake of whole grains, fruits and some vegetables, which raises red flags for health professionals.
"You want to be mindful, because these foods – whole grains, fruits and vegetables – carry a number of beneficial nutrients – vitamins, polyphenols, fiber – that have been shown time and time again to be beneficial for cardiometabolic health.".
What is sad is the number of medical intelligent professionals who keep saying things factually untrue.
1. True Keto diets do not call for no vegetables. In fact many scientific/medical based Keto diets call for 40-50 NET CARBS max. Net carbs means Carbs minus Fiber. Keto diets encourage fiberous vegatables to be eaten and if standard daily recommendation is 20-25g of Fiber a day, numerous keto friendly veggies meet that goal quite easily. You can even have carb veggies as long as you meet your daily net goal
1 Cup of Broccoli 5 grams of Fiber
1 Cup of Avocado 10 grams of fiber
2 Slices of Standard Whole Wheat Bread 4 grams of Fiber.
2. Most Whole grains have vitamins that are added as they are fortified. there is NOT ONE Vitamin or Mineral that Whole Grains have a monopoly on and can only be found there. Vitamins and MInerals can come from various vegetables and some fruits allowed on Keto Diets.
3. Polyphenols are found in Olive Oil, Nuts, vegetables, Dark Chocolate and flaxseed.
So a good Keto diet gets plenty of Vitamins, Polyphenols and Fiber
