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

Discuss
Republish

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. But 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 we drink just water, we are losing an opportunity to get nutrients by drinking tea instead.

To see any graphs, charts, graphics, images, and quotes to which Dr. Greger may be referring, watch the above video. This is just an approximation of the audio contributed by veganmontreal.

    1. 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 http://nutritionfacts.org/?s=super+foods 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.” http://www.ncbi.nlm.nih.gov/pubmed/21485304 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.” http://www.ncbi.nlm.nih.gov/pubmed/21736952 Wheat grass is, as far as the data tells, health promoting! (for more on BPA check out this link http://en.wikipedia.org/wiki/Bisphenol_A#Health_effects as well as Dr. Greger’s video on BPA http://nutritionfacts.org/videos/which-plastics-are-harmful/ )

  1. Hello Dr. Greger,

    I have been a subscriber for a little while now and vegan for several years. I love the informative videos and articles posted on this site. Well done.

    However, there is one thing I have yet to find on this website (or many others) that I would appreciate if Dr. Greger could comment on; demineralized water.

    I have recently become concerned with the amount of heavy metals and VOCs in my municipal water source and have been looking at reverse osmosis or distillation systems for home water consumption. However, there seems to be some controversy over consuming demineralized water (these two systems remove ALL dissolved solids including beneficial ones like Calcium and Magnesium), as it is said to have negative long term consequences to ones health.

    “For about 50 years, epidemiological studies in many countries all over the world have reported that soft water (i.e., water low in calcium and magnesium) and water low in magnesium is associated with increased morbidity and mortality from cardiovascular disease (CVD) compared to hard water and water high in magnesium.”

    http://www.who.int/water_sanitation_health/dwq/nutrientschap12.pdf

    There has been an increase in popularity (that I have even seen expressed though the comments of your subscribers) in only consuming demineralized water. It would be greatly appreciated by not only myself, but many of your subscribers (I assume) if Dr. Greger could address the issue of long term consequences to ones health with the steady consumption of demineralized water.

    Thank you.

  2. Hello Dr. Greger. I LOVE your website. Thank you so much for this valuable public service that you provide. It is nothing short of AMAZING!

    On the topic of water- I hear a lot of advice from the holistic community about the importance of drinking water first thing in the morning (not just children, as this video highlights, but everyone in general), but studies are never provided to back up this claim. While this makes sense intuitively, are there any studies to back up this claim?
