Nutrition Without Calories

What has the opposite of junk food—nutrition but no calories?

So, essentially, we can group foods into one of four categories. There’s stuff that’s nutritious—but has calories, in the upper right; calories, but no nutrition—junk food; and then there’s stuff with neither calories nor nutrition. Is there anything that’s nutritious, but doesn’t add any calories? Well there’s water. That’s good for you and calorie free. How can one add nutrition to the water, though, without adding calories?
We can make some tea. Has all the water of water, but as a bonus is packed with phytonutrients. It’s nutrition, without calories. Every time you drink just water you are losing an opportunity to get nutrients by drinking tea instead.

    So enjoyed watching so many of your video’s, learned a great deal..thank you!
    Question-what’s your thoughts on WheatGrass juicing? Healthy or Harmful?

    • Toxins

      Hello Trinda, I believe I can help you with your question. Wheat grass, like many other “super foods” have been touted as a super healthy substance. But like many other “super foods”, they turn out more harm than good. For example, check out the Star fruit, mangosteen and several spirulina videos Dr. G posted People claim they are healthy but they cause many health detriments. But regarding wheat grass, what does the science say on the subject? Well, according to a study done on rats, it lowered cholesterol, could help prevent heart disease, and i quote the “Phytochemical analysis revealed the presence of flavonoids, triterpenoids, anthraquinol, alkaloids, tannins, saponins and sterols in fresh wheat grass juice.” It appears as though wheat grass is rich in antioxidants and is health promoting. Digging deeper, we can see that for pregnant woman, wheat grass in fact controls BPA toxicity very effectively. “our data suggested potential detoxification of wheat sprouts on BPA-toxicity via antioxidative and interference of absorption, distribution, metabolism and excretion (ADME)-mediated mechanisms in young women.” Wheat grass is, as far as the data tells, health promoting!
