What is the lethal dose (ldl) for caffeine in a human being?
457656
A fatal dose of caffeine has been calculated to be more than 10 grams (about 170 mg/kg body weight) - this is the same as drinking 80 to 100 cups of coffee in rapid succession - not an easy thing to do.\n\n\nhttp://staff.washington.edu/chudler/caff.html

Three cups of orange juice a day over a 4-week period can significantly increase HDL levels \n and improve a patient's LDL:HDL ratio, suggests this small study of healthy adults with \n moderate hypercholesterolemia. When Canadian investigators asked 25 men and women with \n elevated total and LDL cholesterol and normal triglyceride readings to drink 1, 2, or 3 cups of \n juice a day in three separate 4-week periods, those on the highest dose (750 mL) saw their \n HDL levels increase by 21% and their LDL:HDL ratio decrease by 16%. The researchers also \n observed a 30% increase in plasma triglycerides, but those readings remained in the normal \n range. \n\nVitamin C \nThe Dietary Guidelines (2005) have identified vitamin C as a “nutrient of concern” in the American adult diet, because only about 50% of U.S. adults consume adequate levels of the vitamin.(1) As you know, vitamin C is a very important antioxidant that has many functions, such as the promotion of healthy skin and gums. Vitamin C also enhances the absorption of iron from non-heme iron sources (iron-rich grains and other plant foods such as whole-grain cereals) when ingested at the same time as the iron. An easy way to make sure you get adequate amounts of vitamin C each day is by drinking orange juice. Just one 8-ounce glass of Pure Premium orange juice provides a full day’s supply of vitamin C.\n\nPotassium\nWhile you are probably aware that a potassium-rich, low-sodium diet can help maintain healthy blood pressure and help decrease the risk of stroke, a majority of your clients are not. No age group in the United States consumes the recommended level of potassium.(2) For people 14 and older, the recommended intake is 4700 milligrams/day.(2) \n\nSince potassium is found in many foods, but only in relatively small amounts, it is important to educate your clients about foods that are good sources of potassium.Pure Premium orange juice is one of these foods, containing 450 mg of potassium in an 8-ounce glass. Check out the chart below for more potassium-rich foods to recommend to your patients.(1) \n\n \n\nIf you are looking for other foods that contain potassium, try some of these: 1 baked potato (610mg), 3-ounces cooked halibut (490mg), 1/8 medium honeydew (365mg). \n\nFolate\nFolate has a wide variety of benefits including its ability to help reduce the risk of neural tube birth defects and promote healthy red blood cells. Unfortunately some Americans are not getting enough of it. An easy way to help your clients increase folate consumption is by recommending orange juice.Pure Premium orange juice is naturally a good source of folate, providing 15% of the daily value (DV). \n\n2005 Dietary Guidelines Advisory Committee Report. \nInstitute of Medicine, Food and Nutrition Board, 2004.

Between 80 and 120 mg/dl, assuming that they have not eaten within a few hours previously.\nChildren's BG's seem to vary more than adults, possibly because they expend energy so much more "explosively" and have smaller reserves of stored fats.

well caffeine doesn't give you energy per se.\n\nbut what it basically does is give you an "energy high."\n\nwhat this means is that it speeds up your metabolism, making everything seemingly faster.\n\nnow, the reason why caffeine may be bad for you is that it basically messes up your metabolism, which are usually the "caffeine lows" which are basically when you feel like you have no energy.\n\nso thats why. also it can become addictive. also it may be bad for you skin.

USA Today states:\n “Although psychological dependence on caffeine has yet to be widely documented, a physical dependence upon the drug is very evident. Caffeine dependence can be seen if a person consumes as little as 100 mg. a day, and then tries to stop taking in caffeine. \n\nUSA Today continues that withdrawal symptoms, “which includes headache, fatigue, inability to concentrate, and even nausea and vomiting, can be experienced by those trying to kick the habit.  \n\nThe Marie Claire magazine writes, “Women who consume 250 mg of caffeine daily (that's two to three cups of coffee) have been shown to take slightly longer to conceive, and that, “During pregnancy, consuming the caffeine in five or more cups of coffee a day doubles your risk of miscarriage."\n\nCoffee also dehydrates you rapidly, one cup of coffee needs 2-3 glasses of water to replace the fluid.\n\nHaving said that i drink about 6-8 cups a day and i'm still alive. But i do drink, smoke, drive a car...etc all things that are gonna kill you a lot quicker and do much more harm

Biologically speaking, caffeine impedes the speed of cell reproduction. So seeing as how thousands and thousands of dead skin cells are shed each day, we replenish our cells constantly. Caffeine also severely dehydrates you.\n\nBut as long as you watch your caffeine intake and hydrate, no problems should be too noticeable.

All of those energy drinks have massive amounts of caffine in them. If you drink them regularly, then yes, they are very bad for you because you'll be addicted to caffine. If you just drink it once a week, then there isn't anything wrong with that.

HDL, LDL, Triglycerides and Cholesterol are all different things that they are testing.  \n\nThe American Heart Association provides a set of guidelines for total (fasting) blood cholesterol levels and risk for heart disease[5]:\n\nLevel mg/dL Level mmol/L Interpretation \n<200 <5.2 Desirable level corresponding to lower risk for heart disease \n200-239 5.2-6.2 Borderline high risk \n>240 >6.2 High risk \n\nHowever, as today's testing methods determine LDL ("bad") and HDL ("good") cholesterol separately, this simplistic view has become somewhat outdated. The desirable LDL level is considered to be less than 100 mg/dL (2.6 mmol/L), although a newer target of <70 mg/dL can be considered in higher risk individuals based on some of the above-mentioned trials. A ratio of total cholesterol to HDL —another useful measure— of far less than 5:1 is thought to be healthier. Of note, typical LDL values for children before fatty streaks begin to develop is 35 mg/dL.\n\nPatients should be aware that most testing methods for LDL do not actually measure LDL in their blood, much less particle size. For cost reasons, LDL values have long been estimated using the Friedewald formula: [total cholesterol] − [total HDL] − 20% of the triglyceride value = estimated LDL.\n\nIncreasing clinical evidence has strongly supported the greater predictive value of more-sophisticated testing that directly measures both LDL and HDL particle concentrations and size, as opposed to the more usual estimates/measures of the total cholesterol carried within LDL particles or the total HDL concentration.

amphetamines are very dangerous..they are multiple strong doses of caffine like about 50 cups of coffee at once..it raises your heart rate tremendously and can cause heart attack if there is a underlying problem even if you are youn...find a doctor and consult with them

Lethal doses are usually measured in something like grams per kilogram of body weight.\n\nYou can find the lethal dose of marijuana at http://druglibrary.org/schaffer/library/mj_overdose.htm\n\nThe lowest estimate is about one-third your body weight. The highest is 1,500 pounds - consumed in fifteeen minutes.\n\nIf by "overdose" you mean "enough to make you uncomfortable", that depends on the person. Novices can experience it quite readily. Experienced users can consume large quantities with no apparent ill effects -- other than going to sleep of wanting to eat.\n\nFor heroin, the "overdose" amount (that which will kill) is open to question. For inexperienced users, the amount can be fairly small. Addicts, on the other hand, can take quite large doses of pure heroin with no ill effects. See, for example, Chapter 12. The "heroin overdose" mystery and other occupational hazards of addiction at http://druglibrary.org/schaffer/Library/studies/cu/cu12.htm\n\nIt is believed that most cases of heroin "overdose" in the US are really the result of impurities in the black market heroin. See the article linked above for a fuller explanation.\n\nOverdose deaths from cocaine are actually fairly low in the US - a few thousand per year -- about the same number as die from common drugs like Tylenol.

No-doze (caffeine pills), anything that says decongestant (which includes sudafed), methylxanthines in chocolate, nicotine gum. Be cautious and avoid energy pills - there any many variations of the now-illegal ephedra which is seriously dangerous.\n\nGood luck!

It all depends on how much different you expect the results to be between the experimental group and the control group. I am on simvastatin and have gone periods drinking more green tea. Have not watched my HDL levels closely enough to compared effects. \n\nI use statcalc in EpiInfo to run sample size calculations and find that is easy and accurate. I think that would work for your experiment and your question.

In non-smokers, the opposite effect has been noted.\n\nA randomised trial into the use of β-carotene and Vitamin A for prevention of lung cancer had to be stopped early due to the apparent increase in the incidence of lung cancer in those with lung irritation from smoking or asbestos exposure.
