L'idratazione è importante (vedi ad esempio Bere acqua rende i bambini più intelligenti? (https://nutritionfacts.org/video/does-a-drink-of-water-make-children-smarter/)) ma è così se possibile evita gli inquinanti presenti nell'acqua (ad esempio piombo nell'acqua potabile (https://nutritionfacts.org/video/lead-in-drinking-water) e benefici della curcuma per l'esposizione all'arsenico(https://nutritionfacts.org/video/benefits-of-turmeric-for-arsenic-exposure/)). <br/>

  2. Why bother Shadow banning comments when you can erase the first draft of this video and replace it with this one.  Yes, I know the audio was fixed on the second upload.

  3. What about THM's from Disinfection By Products DBP's?   Why not talk about these cancer causing THM's or fluoride?   Seems you kind of side stepped the obvious when talking about "Is it Best to Drink Tap, Filtered, or Bottled Water"?  What about chlorine and chloramine?  Are these Best to ingest?  Which is Best?   What about all the studies about DBPs?   Surely there must be some scientific proof DBP tainted water is not BEST, right?

  4. If bacteria can be spewed up with one flush of a toilet… what about all the THM's created as soon as your turd hits the chlorinated toilet water?   Or, the THM's produced in a garbage disposal?  Or the THM's while washing chicken in chlorinated tap water?

  10. I only drink home distilled, zero plastic contact, about 4 litres a day.
    Distilled is unbelievably palatable, I can drink a whole litre first thing in the morning at once with no sick feeling. If I try that with bottled or tap water it’s impossible to resist the gag.
    Mineral loss is irrelevant, it’s tiny compared to the minerals you should be getting from your food, and a lower total dissolved solids (0-1 ppm in distilled, 300+ ppm in bottled and tap) makes the water better able to accept waste products from the rest of your body and transport it out through the urine.

  13. Bernando Lapallos lived to 114 (ate a primarily vegan diet, but ate fish 2 to 3 times a week also), was never sick a day in his life and always went on a 2 km walk everyday and read and kept learning (to keep his body and mind active). His website is agelesslivemore and he has written two books). He used to boil his tap water and then put it in the fridge to kill bacteria that could be in the water. He also ate a low fat diet and ate his food raw or mildly sautéed in 1 to 2 tbsp od olive oil daily).

  18. There is a problem with very old pipes leaching metals and rust into tap water in many cities and states. Don't drink tap unless that is all you have OR better yet put it through a filter. I disinfect my brush after each use. I have done this for me and my son for several years.

  21. What about collecting rainwater to drink? If you can disinfect a toothbrush, you should be able to disinfect your water filter with the same method. Maybe?

  25. Why didn't they test a Berekey water filter set up? And what about bottled water from natural springs? We avoid plastic bottles etc, but a lot of people buy bottled spring water which is not filtered. As for tap water NYC has good tap water and our well water here in the California Sierra is awesome.

  29. The Zero Water pitcher does remove lead (unlike the other pitcher systems) but is notorious for getting bacteria built up in it resulting in a fishy smell (look up the reviews online). It's horrible. Tap filters like Pur can remove lead (they're used in Flint today) and don't have this fishy issue, but you do need to swap them out regularly and don't ever run warm water through them.

  30. LOL even tho you can disinfect your tooth brush and keep it going longer the bristles loose their capacity to clean making your case about keeping it longer MOOT. Filters, brushes anything that gets used often typically does NOT last forever and yea it needs replacing. I hope you replace your HVAC filters, your cars in cabin air filter, your cars engine filter, your razor blades, your office air purifiers need replacing too! C'mon guys this is ridiculous and i feel you should know better.

  35. Isn't over-disinfection a problem that makes kids allergic to stuff and gives us all weak immune systems? I don't swallow my toothbrush juice, and I rinse my mouth right after I brush, so I don't really see how it could be so bad.

  41. I can't stand the plasticy taste that most mainstream pitchers leave in the water, which gets especially bad as the months and years go on using the same pitcher. Does anybody know of a non-plastic pitcher for sale? I don't care about plastic being on the filter (I imagine that using non-plastic filters would start to get expensive), but it's the plastic pitcher itself that leaves a taste that I can't stand.

  43. i wouldnt drink tap water becuse of the chlorine, i would use it to rinse my toothbrush tho, since it kills bacteria and all, tho id rather not have any chlorinated water ideally

  44. When I need to disinfect, I use vodka — Clean/wipe/dip/soak anything in that, and I'm feeling confident everything is decimated!

  50. What's your thoughts on Primo water I have been using primo water for a while the fill your own bottles at Walmart for 39 cents a gallon

  51. More bacteria = dirtier ? Our gut must be the one of the dirtiest places then. It's important to differentiate good and harmful bacteria, something those studies doesn't seem to do (the water filter ones).

  59. I've been very happy with the Zero water filter. It has a device to let you know when it's time to change the filter. Tastes great!

  60. Wondering what the thoughts are regarding CVI and swelling when too much sodium intake, I guess?

    Went on a binge eating Jack's frozen pizza's and ankles started swelling again.

    I use bottled and lately distilled water with my tea and half and half and am wondering what is the best supplement for the distilled or bottled water since is most likely demineralized?

    I had this happen before and I think is related to issues like with the U.S. Diplomats, Staff, Family and others in Cuba and China that came out well disclosed more-so in the CBS News 60 Minutes report on Sept. 1 st 2019: https://www.cbsnews.com/news/is-an-invisible-weapon-targeting-u-s-diplomats-60-minutes-2019-09-01/

    Even so, main question and concern is going to be how to get my mineral intake optimized in my known clean safe water source.

    Stretching exercises got the swelling down along with no more processed foods that have the high sodium, i.e. 500mg per serving as the worst was the Shin Ramyun Noodle Soup at 1970mg per 2 serving bag that I haven't used in a few weeks since I noticed before this round was causing… though I didn't notice the slight discoloration above the ankles like spider veins and like red/purple under the skin and the freckles that I assumed prior were from sand flea bites. Time to start up some calisthenics once this swelling has stabilized and I get rid of the discoloration. The warmth period went away, so that's good. No edema now.

    http://dewdetectionprojects.blogspot.com/2019/12/went-to-pick-up-sears-ss16-for-some.html (probably can photograph this incident too as I just made two instructables, ~450MHz Yagi and Spiral Conical Antenna the Form, for detecting and wondering if that irritated the remote operators)

    Reading this WHO document ( https://www.who.int/water_sanitation_health/dwq/nutrientschap12.pdf ) I'm thinking will be more cost effective to invest in some food or pharma grade minerals and supplement what's not in the ratio of the for example… Real Salt.

    This is what I got out of reading and am still working on narrowing down though figured I'd note online for some feedback:

    The 1980 WHO report

    Salts are leached from the body under the influence of drinking water with a low TDS.

    Because adverse effects such as altered water-salt balance were observed not only in completely

    desalinated water but also in water with TDS between 50 and 75 mg/L, the team that prepared the

    1980 WHO report (3) recommended that the minimum TDS in drinking water should be 100

    mg/L. The team also recommended that the optimum TDS should be about 200-400 mg/L for

    chloride-sulphate waters and 250-500 mg/L for bicarbonate waters (WHO 1980). The

    recommendations were based on extensive experimental studies conducted in rats, dogs and

    human volunteers. Water exposures included Moscow tap water, desalinated water of

    approximately 10 mg/L TDS, and laboratory-prepared water of 50, 100, 250, 300, 500, 750, 1000,

    and 1500 mg/L TDS using the following constituents and proportions: Cl-

    (40%), HCO3 (32%),

    SO4 (28%) / Na (50%), Ca (38%), Mg (12%). A number of health outcomes were investigated

    including: dynamics of body weight, basal and nitrogen metabolism, enzyme activity, water-salt

    homeostasis and its regulatory system, mineral content of body tissues and fluids, hematocrit, and

    ADH activity. The optimal TDS was associated with the lowest incidence of adverse effect,

    negative changes to the human, dog, or rat, good organoleptic characteristics and thirst-quenching

    properties, and reduced corrosivity of water.

    In addition to the TDS levels, the report (3)

    Based on the currently available data, various researchers have recommended that the

    following levels of calcium, magnesium, and water hardness should be in drinking water:

    • For magnesium, a minimum of 10 mg/L (33, 56) and an optimum of about 20-30 mg/L (49,

    57);

    157

    • For calcium, a minimum of 20 mg/L (56) and an optimum of about 50 (40-80) mg/L (57,

    58);

    • For total water hardness, the sum of calcium and magnesium should be 2 to 4 mmol/L (37,

    50, 59, 60).

    At these concentrations, minimum or no adverse health effects were observed. The

    maximum protective or beneficial health effects of drinking water appeared to occur at the

    estimated desirable or optimum concentrations. The recommended magnesium levels were based

    on cardiovascular system effects, while changes in calcium metabolism and ossification were used

    as a basis for the recommended calcium levels. The upper limit of the hardness optimal range was

    derived from data that showed a higher risk of gall stones, kidney stones, urinary stones, arthrosis

    and arthropathies in populations supplied with water of hardness higher than 5 mmol/L.

    Long-term intake of drinking water was taken into account in estimating these

    concentrations. For short-term therapeutic indications of some waters, higher concentrations of

    these elements may be considered.

    All four Central European countries that became part

    of the EU in May 2004 have included the following requirements in their respective regulations

    but varying in binding power;

    • Czech Republic (2004): for softened water ≥ 30 mg/L calcium and ≥ 10 mg/L magnesium;

    guideline levels of 40-80 mg/L calcium and 20–30 mg/L magnesium (hardness as Σ Ca + Mg

    = 2.0 – 3.5 mmol/L).

    • Hungary (2001): hardness 50 – 350 mg/L (as CaO); minimum required concentration of 50

    mg/L must be met in bottled drinking water, new water sources, and softened and desalinated

    water.

    • Poland (2000): hardness 60–500 mg/L (as CaCO3).

    • Slovakia (2002): guideline levels > 30 mg/L calcium and 10 – 30 mg/L magnesium.

    The Russian technical standard Astronaut environment in piloted spaceships – general

    medical and technical requirements (64) defines qualitative requirements for recycled water

    intended for drinking in spaceships. Among other requirements, the TDS should range between

    100 and 1000 mg/L with minimum levels of fluoride, calcium and magnesium being specified by

    158

    a special commission separately for each cosmic flight. The focus is on how to supplement

    recycled water with a mineral concentrate to make it “physiologically valuable” (65).

  61. Disturbing to me the lack of quality remineralization products on the market that aren't tainted with something not so natural or very limited in the remineralization nutrients.

  63. Just image how much crap you are breathing in when you use a public toilet. There might have been 1000 people doing there business before you did your business. Happy thoughts.

  68. I do what Zimmy does: put the toilet lid down before flushing. Rather than getting a new toothbrush every 3 months, I soak all the family brushes in hydrogen peroxide (3% available everywhere) each month. As always, appreciate the video Dr. Greger!

  72. Why does this absolute bellend read with this bizarre roar/drawl like he's struggling with bowel movements.

  77. Careful going all hog wild with disinfectant… lots of research is showing it may be our emphasis on neutralizing microbes that leads to auto immune disorders later in life. It seems you just can’t win.

  79. Zero water makes has a water purity meter that costs about $20 that is handy for checking water purity. It is really only helpful if about a reading of 2 or less. Other water testing can get expensive.

  82. You should boil water first before running through the filter. Plus I don't keep my battery powered toothbrush in the bathroom. LOL
