Well, my wife works for Martinelli's - and it definitely doesn't take 2+ apples to make a cup of apple juice. (I'm not saying that apple juice should be your first choice.) They also carefully monitor "brix", which is the amount of sugar in their juice. They have acceptable targets for that as well as other measures (including John Martinelli tasting the product almost daily.) Personally, I use my Vitamix to make my…

Can you ask your wife what the stuff that appears to be floating in my Martinelli apple juice is? It's a cloud looking like substance in my juice. Does that mean it's been sitting too long? Fermented apple by chance? Smells almost like alcohol when opening it.

I may know what the cloudy stuff is. First, if the juice is outside the "best buy" date, just throw it away. The "cloudy juice" problem happened when they moved to a new production line in Watsonville. They discovered that as juice aged it got cloudy and then started to grow a "tree looking" like thing inside the bottle. It took them months to figure out that the big warehouse doors where they brought in apples was allowing mold spores to blow into the air and contaminate the juice. You've probably been holding on to that bottle for a while. (Some other brands don't filter their juice, and will appear cloudy.) This isn't a problem that anyone should be seeing anymore. (I should add that many, many bottles were tested and the mold wasn't a harmful mold. Many skeptical customers even arranged their own testing.)

Something doesn't have to cross the barrier to cause a headache or other effects. A constriction or dilation of the blood vessels in the brain will do.

What evidence is there that glutamic acid is a vasodilator?

Just found some pig and rat experiments:

http://www.ncbi.nlm.nih.gov/pubmed/2572176

"We examined the effects of topically applied amino acids (glutamate, aspartate, glycine, and taurine) and a synthetic glutamate analogue [N-methyl-D-aspartate (NMDA)] on pial arteriolar tone and cortical surface cerebrospinal fluid (CSF) dilator prostanoid concentrations in anesthetized newborn pigs. [...] We conclude that these amino acids are potent dilators of the neonatal cerebral circulation."

http://www.ncbi.nlm.nih.gov/pubmed/9134957

"Taken together, these results indicate that glutamate contributes to the dilatory tone of cerebral microvessels under physiologic conditions and that this effect is mediated by NMDA receptors. Glutamatergic vasodilation is dependent on neuronal discharge activity and the neuronal production of NO."

Experiment with glutamate infusion in cardiac surgery patients:

http://www.ncbi.nlm.nih.gov/pubmed/11724641

"These data show that an intravenous glutamate infusion after routine CABG surgery significantly improved cardiac haemodynamic performance without direct effects on cardiac substrate metabolism. This suggests that a reduction of the afterload via a peripheral vasodilatory effect is the main mechanism leading to the observed changes in haemodynamics."

I hope you dont mean pure h2o because that's dangerous.

I am very curious about your comment. how is pure h20 dangerous?

Distilled water (pure) has such a low mineral/salt level that it pulls important salts out of your cells. Your body is mostly water, but it's mostly salty water.

I only ever buy cloudy apple juice. Or is there something else going on in Martinelli?

"Juice removed from the fruit is just concentrated fructose without any of the naturally-occurring fiber, pectin, and other goodies that make eating a whole fruit good for you. Did you know, for example, that it takes 6-8 medium sized apples to make just 1 cup of apple juice? You probably wouldn’t be able to eat 6-8 medium apples in a single sitting. (I know I can barely eat one!) But you can casually throw back a cu…

It sounds reasonable that fiber could reduce the rate of aborption of sugar. But I lose you when you start talking about sugar highs. I thought that was dispelled as a myth after a number of placebo controlled studies.

I'll just remark that for water, I do want to drink a pure chemical, possibly with a little bit of minerals in, if it can't be helped.

Those little minerals are important. Purified water will pull minerals out of your system through osmotic pressure. http://www.who.int/water_sanitation_health/dwq/nutrientschap...

Just eat something with it. Anything.

I did that at Edeka in Germany recently. It was the only time I bought orange juice that literally tasted fresh made. Well, because it was ^.^

I've been living in Germany for 6 months now and I'm so impressed by the availability of natural products. There is at least one Biomarkt ("natural supermarket") in walking distance pretty much everywhere in Berlin. There's also startups like Bonativo which deliver fresh and locally produced products and produce regularly (it is a bit expensive though). I love that there are at least these options should you want the…

Even Aldi sells lots of organic stuff these days.

Wow. Interesting and makes plenty of sense. Thank you.

To be specific, I was trying to describe the "tree looking" like thing inside the bottle.
