OMG! Diet Coke is good for you!

Did a little googling, and was interested to find this:

"Interestingly enough, the drink does not provide calcium—one of the key minerals said to be lost when caffeine is consumed."

Well, that's just a nasty rumor. A complete untruth. What are you thinking, getting your info from google? Humph!!!!>:(

Actually, in taking nutrition classes it is well known that vitamins and minerals cannot be absorbed by the system when there's caffiene there.

Rule of thumb is to take your vitamins/minerals at least 30 minutes before or 30 minutes after drinking your coffee in the morning. Otherwise you're just pissing your nutrients away.

I'd really like to know what the mechanism is that makes that true. I can see some less efficient handling of nutrients, but "cannot be absorbed?" Knowing how the gut works, I'm just not seeing it. Wanna shed some light on it for me?

Effect of a mixture of caffeine and nicotinamide on the solubility of vitamin (B2) in aqueous solution.

Evstigneev MP, Evstigneev VP, Santiago AA, Davies DB.
Department of Physics, Sevastopol National Technical University, Studgorodok, Sevastopol, 99053 Crimea, Ukraine. max_evstigneev@mail.ru
The effect of caffeine (CAF) and nicotinamide (NMD) on the solubility of a vitamin B2 derivative (FMN) has been evaluated for mixtures containing either a single hydrotrope (CAF or NMD) or the two hydrotropes simultaneously. A model for analysis of ternary systems, which takes into account all possible complexes between the molecules, has been developed and tested with experimental NMR data on the three-component mixture FMN-CAF-NMD. The results indicate that special attention should be given to the concentration of a hydrotropic agent used to enhance the solubility of a particular drug. A decrease in the efficacy of solubility of the vitamin on addition of large amounts of hydrotropic agent is expected in the two-component systems due to the increased proportion of self-association of the hydrotrope. It is found that a mixture of two hydrotropic agents leads to an increase in the solubility of the vitamin in three-component compared to the two-component system. Rather than using just one hydrotropic agent, it is proposed that a strategy for optimising the solubility of aromatic drugs is to use a mixture of hydrotropic agents.

Caffeine decreases vitamin D receptor protein expression and 1,25(OH)2D3 stimulated alkaline phosphatase activity in human osteoblast cells.

Rapuri PB, Gallagher JC, Nawaz Z.
Bone Metabolism Unit, Creighton University, School of Medicine, 601 North 30th Street, Omaha, NE 68131, USA. thiyyari@creighton.edu
Of the various risk factors contributing to osteoporosis, dietary/lifestyle factors are important. In a clinical study we reported that women with caffeine intakes >300 mg/day had higher bone loss and women with vitamin D receptor (VDR) variant, tt were at a greater risk for this deleterious effect of caffeine. However, the mechanism of how caffeine effects bone metabolism is not clear. 1,25-Dihydroxy vitamin D(3) (1,25(OH)(2)D(3)) plays a critical role in regulating bone metabolism. The receptor for 1,25(OH)(2)D(3), VDR has been demonstrated in osteoblast cells and it belongs to the superfamily of nuclear hormone receptors. To understand the molecular mechanism of the role of caffeine in relation to bone, we tested the effect of caffeine on VDR expression and 1,25(OH)(2)D(3) mediated actions in bone. We therefore examined the effect of different doses of caffeine (0.2, 0.5, 1.0 and 10mM) on 1,25(OH)(2)D(3) induced VDR protein expression in human osteoblast cells. We also tested the effect of different doses of caffeine on 1,25(OH)(2)D(3) induced alkaline phosphatase (ALP) activity, a widely used marker of osteoblastic activity. Caffeine dose dependently decreased the 1,25(OH)(2)D(3) induced VDR expression and at concentrations of 1 and 10mM, VDR expression was decreased by about 50-70%, respectively. In addition, the 1,25(OH)(2)D(3) induced alkaline phosphatase activity was also reduced at similar doses thus affecting the osteoblastic function. The basal ALP activity was not affected with increasing doses of caffeine. Overall, our results suggest that caffeine affects 1,25(OH)(2)D(3) stimulated VDR protein expression and 1,25(OH)(2)D(3) mediated actions in human osteoblast cells.

Caffeine and nicotinamide enhances the aqueous solubility of the antimalarial agent halofantrine.

Lim LY, Go ML.
Department of Pharmacy, National University of Singapore, 10 Kent Ridge Crescent, Singapore, Singapore.
The aqueous solubility of the antimalarial agent halofantrine in phosphate buffers pH 5.9 and 7.0 (ionic strength 0.08) is increased by the addition of caffeine and nicotinamide. Solubility is increased to a greater extent in the presence of caffeine (12.5-125 mM) than nicotinamide (125 mM -2.0 M). The greatest increase in solubility was observed at pH 5.9 where the basal solubility of halofantrine rose from 0.91 to 435 microM when 125 mM caffeine was added. Phase solubility studies support the formation of a 1:1 complex between caffeine and halofantrine which is characterised by a K(1:1) constant of 2.75x10(3) M(-1) (pH 5.9). A less stable 1:1 complex is formed at pH 7.0 (K(1:1)=6.37x10(3) M(-1)). Differential scanning calorimetry of solid mixtures of caffeine and halofantrine showed the absence of the endotherms of the two drugs and the appearance of a distinct endotherm (with a smaller enthalpy) characteristic of the complex. An analysis of the 1H-NMR spectra of mixtures of caffeine and halofantrine revealed perturbations in the chemical shifts of the methyl group and proton at positions 4 and 8 of caffeine, and a change in splitting pattern of the H(9) proton of the phenanthrene ring in halofantrine.

I see the bone issue, but I'm wondering about the "can't absorb nutrients" thing. That's just not something I'm aware of. I've wondered about the mechanism for bone density loss, and that's what I think of when it comes to caffeine. But what about other nutrients? That's just not something I'm aware of.

Be happy to. My nutrition books are packed somewhere in the garage, and would be too laborious to type here the chapters on this subject. However, let me try and find a web page that states what we know.

Okay, here's a decent one.

http://www.teeccino.com/ArticleDetails.aspx?ArticleID=15

"Metabolic acidity is a condition that creates a high demand for minerals to rebalance the body’s natural alkalinity. All foods must be buffered so that the body’s tissues, blood and other fluids are maintained at the normal slightly alkaline pH of 7.3 to 7.4 – quite a specific and narrow range for optimal health. Alkaline minerals such as calcium, potassium and magnesium are the buffering agents that the body uses to achieve this alkaline balance. If your diet is acidic and doesn’t supply adequate minerals, your bones and teeth will become the reservoirs the body uses to get the minerals required to readjust the acidity to alkalinity.

A simple yet accurate definition of “acidic foods” is those foods that don’t supply alkaline minerals. Both regular and decaf coffee, tea, meat, sugar and refined carbohydrates are all acidic foods that can cause your body to be robbed of minerals if you don’t have an adequate supply in your diet. Although most fruits and vegetables are alkaline because they are high in minerals, lemon juice, for instance, is an acidic food because it doesn’t have a high mineral content to balance its low acidity pH of 2.2-2.3.

As we age, the body becomes more acidic because the digestive tract becomes less efficient at absorbing minerals and its mineral reserves may be depleted. Metabolic acidity can make you susceptible to illness and disease, including fatigue, digestive problems, bladder infections, Candida yeast infections, osteoporosis, rheumatoid arthritis, colds, flu, and allergies. Thus if you are eating highly acidic foods, make sure you include foods and beverages high in the alkaline minerals calcium, magnesium and potassium so your body can maintain a healthy alkaline metabolism. "


--(btw, this was confirmed by a very good friend who was found to have breast cancer several years ago. They wanted to do bilateral radical mastectomies. She started studying and found the fact I quoted above. She completely changed her lifestyle, including giving up her multiple cups of coffee in the morning (coffee being acidic), and when tested again 6 months later her cancer was completely gone!. Spoke volumes to me.

Excuse me, people, but I don't know why you insist on muddying my point with documented fact.

I don't appreciate it at all.

I already KNEW it was BS that diet coke was good for me, but I was trying really hard to believe the fantasy.


I'm taking my ball and going home now. Thanks for ruining it for me.:(:(

Thanks. That's pretty much what I would expect, but not what I thought you were saying. Thanks for clarifying, and thanks for a good article. That's something that can be helpful to all! :)

Does this mean that all this time that I've been taking my vitamins and minerals WITH my Diet Coke, I've just been pissing them all away? :o

No [B]WONDER[/B] I pee so much!!! >:(

I like Diet Coke with Lime but the Coke rep told me that they are phasing it out.



NOOOOOOOOO....I LOVE Dt. Coke with lime, loved the lemon too but they already got rid of that. >:(

Guess I'll just have to mix my dt. coke with bicardi limon.
:)
