That's what I do when an assertion or conclusion doesn't quite ring true. I ask myself: If the USDA database was populated in the 1950's by slave labor (grad students) and never verified, what might I also expect to be true or to happen? 1. The data would conflict by food databases from other countries. For example, Australia: <http://www.foodstandards.gov.au/science/monitoringnutrients/ausnut/ausnutdatafiles/Pages/foodnutrient.aspx> Line number 2653 for "Banana, cavendish, peeled, raw" shows 346mg potassium, which is quite close to the USDA nominal figure of 358mg per 100grams. I haven't checked any other databases, but I can look around for discrepancies if necessary. 2. Food and supplement producers that rely on potency claims to sell their products would have an interest in stabilizing the official figures so that their products would always be higher potency than typical. A common variation of this need for stability is the declared weight of the contents of packaged food. The weight can be greater, but never less than the stated value (unless the listed item is deemed undesirable). Same with nutritional values. 3. The nutritional values listed have been used in thousands of health and medical experiments since the database was corrected. If there were any errors, experiments based on the data would also show discrepancies or at least large variations in results which would attract suspicion. I haven't seen any of that in the press.

| jurb6006@gmail.com: Nov 28 01:06AM -0800 >"Enough for now." Not quite. I do not question their numerical accuracy, and in fact it really isn't all that critical nor could it be. Vitamins are irrelevant, minerals are what you need. Their numerical accuracy means nothing, like the number of grains of rice per capita in Zimbabwe. (probably among the lowest in the world lol) I would like to see the figures on all 24 of the minerals recognized as essential by every health organization in the world not run by hyenas. And being essential, and recognized as such, how come they are not out spreading information about that ? Energy, ba. Fiber, I shit just fine. What's next, ash like in fish food ? Gimme the numbers on the minerals dammit. Database for the email. Draw your own conclusions. Don't say I didn't offer. Look at; https://ndb.nal.usda.gov/ndb/foods/show/45287885?fgcd=&manu=&format=Full&count=&max=25&offset=&sort=default&order=asc&qlookup=bone+broth&ds=&qt=&qp=&qa=&qn=&q=&ing= TWENTY FOUR recognized as ESSENTIAL. Count how many they give. And it is impossible for the ones not mentioned to be of insignificant quantity because the livestock is given mineral (not vitamin)supplements. They require approximately the same 24 we do, and they are there but not reported. Here they give more; https://ndb.nal.usda.gov/ndb/foods/show/12078 Why ? Beef bone broth MUST have more different minerals in it than ANY plant for the same reason we need them.Plants do not move, breathe, think, talk, any of that shit. they are fertilized with what they need,nit what we need. The producers are paid by the pound,not the content. Why pay like 50 times as much on enriching the soil for ZERO PROFIT. Most people don't know shit about essential minerals so it is of absolutely no advertising value. With that and extremely higher costs of operation, would YOU ? Would YOU care enough about your fellow Man to go broke giving them good foods in the market with zero recognition for it, and like I said, go broke. Your kids starve so total strangers are more healthy ? That is not the American way, hell that is not the anything way. |

Also, the trouble >is intermittent. What can I do? Is there some >sort of filter to fix it? The first question I would ask is, "What's your antenna setup?" For TV, and for FM radio, the most important aspect to getting good signal quality is having a good antenna arrangement - a proper antenna mounted where it can "see" the transmitters with a minimum of interfering solid matter between the two. Indoor antennas - "rabbit ears", floppy dipoles, and small wall-mount panel antennas - are usually suitable only for "strong signal" areas fairly close to the transmitters. Modern buildings are often quite effective shields against RF transmission - they contain materials which either absorb or reflect RF - steel beams, wire mesh in stucco walls, metallized plastic insulation and vapor barriers, and so forth. Signals from distant stations don't stand a chance... they're weakened, and also degraded by multipath (multiple RF paths of different lengths, caused by signal reflections, which result in frequency-selective signal reinforcement and cancellation). The results of all of this are bad signals. Analog TV suffers from noise and "ghosts". FM suffers from noise and distortion. Digital TV suffers from pixellation, freezing, and "no signal found" problems. These problems can all be made worse by local interference, radiated or conducted. They're also made worse by short-term multipath - e.g. signal reflections from airplanes flying within the line-of-sight, or even trucks driving by on the road outside. On FM you can hear a "picket fencing" effect when this happens, on analog TV you see moving "ghosts", and on digital TV you see pixellation and freezing. Digital TV receivers do have the ability to detect and cancel out some multipath reflections, but dealing with rapidly changing reflections is a "hard problem" for them and they often don't adapt fast enough. Filters at the receiving end (TV, FM radio) won't help, except in the case where the TV is picking up _conducted_ RF interference through the power line. Can't hurt to try, but don't expect miracles. Filters at the sources of interference (noisy motors, PC power supplies, LED lights, light dimmers) may help somewhat. However, even if you completely filter all local noise sources, there can still be plenty of noise from outside the house/apartment - neighbors' equipment, etc. The real "fix" is to improve the quality of the incoming RF signal... you want a strong signal with minimal multipath. This often requires an outdoor antenna - one mounted up "in the clear" (e.g. on a roof mast). If possible, install a directional antenna which is aimed in the direction of the desired transmitter - this both boosts the amount of "good" signal (thanks to the antenna's gain) and also reduces the amount of "bad" signal (multipath reflections coming in from other directions, and random interference from sources in the area). If necessary, install a remote-controlled antenna rotator, or an electronically-rotatable antenna (if your TV has the ability to control one of these - most do not, I believe). If you're getting your over-the-air TV signal via a cable-TV feed, and the quality is still poor, then check your coax connections, and/or complain to the cable company. |
