No Calcium is demonstrably false. Same goes for Magnesium and Phosphorous with pretty much the same links. And Vitamin D is straight up bulltrout because it's added to milk after the fact, is readily available in other foods, and the largest source of the stuff for humans is from sun exposure anyway.No dairy? No calcium, vitamin D, magnesium or phosphorus.
If you're trying to get your fiber, anti-oxidants and vitamins from grains then you're doing it wrong. They terrible sources of fiber compared to fruits, vegetables, nuts and seeds, and they'd be utterly devoid of anti-oxidants and vitamins if they weren't added in after the fact. And even then, they're a very poor source of the stuff compared to whole foods. Anyone who told you otherwise has never bothered to check the actual nutrition labels.No grains? No fiber, few antioxidants, and again, some lost vitamins.
