    What about adding black raspberry seed oil to salads?

  • LOL @ “Let them take the long way around”.

    Excellent video. Black raspberry smoothies for the win.

    what about HPV related warts and anal cancer? I wonder by the time it travels through your digestive tract, how much nutrients are still there from the berries we eat?

    • Toxins

      Just a comment, but the nutrients will be in your bloodstream at that point and will have dispersed throughout your entire body. The large intestine, the last stop before exiting your body, does not absorb nutrients, but water. But even if it did absorb the nutrients, it wouldn’t matter because what nourishes it is not the food itself, but the blood that delivers the nutrients from the food.

    I eat black raspberries as often as possible, because they are full of calcium and fiber, necessary ingredients when one has osteoporosis.

    I just watched your video on High cholesterol being, possibly, the single cause of heart disease. I have high cholesterol. I have been on a vegan diet for over 5 years and I use very little oil in my diet. I don’t cook with oil, but when I eat out (about once a week) I do eat food food that has oil. I also eat tahini, almond butter and nuts and seeds.
