Vegetarian and Kangatarian

A study by the US Humane Research Council revealed that 84 percent of modern-day vegetarians gave up their new diet less than a year after they started. The participants included 11,000 vegetarians, former vegetarians, and non-vegetarians in the United States. According to the study, 88 percent of Americans above age 17 have never gone vegetarian, 10 percent are former vegetarians, and 2 percent are vegetarians. However, only one in five vegetarians stay that way with the rest returning to eating meat. Of that figure, one-third dumped the vegetarian diet after three months while the rest got rid of it in less than a year. One-third of vegetarians said they started eating meat after they got into a relationship with someone who ate meat. Others went back to meat due to health, financial, or social reasons. All former vegetarians ate less meat than they did before they became vegetarians.

A new group of vegetarians has popped up in Australia. They are kangatarians, vegetarians who only eat kangaroo meat. Kangatarians usually stop eating meat for ethical reasons. Ethical vegetarians do not like the way that animals are reared and slaughtered on farms. Australia has an abundance of wild kangaroos and since they are not reared on farms, these vegetarians have no qualms about eating them. Kangatarians further justify their consumption of kangaroo meat by claiming that kangaroos are greener for the environment since they do not produce as much ozone-destroying methane as cattle and sheep raised on farms.

Vegetarians can receive all the vitamins and minerals they need from a plant-based diet except vitamin B12, which is available in meat, fish, eggs, and dairy. Vegetarians could get this vitamin from vitamin-enriched cereals and supplements, but it is not usually enough. Vitamin B12 deficiency can trigger the excessive production of homocysteine, leading to depression, fatigue, weakness, nausea, constipation, anemia, heart disease, and stroke. The people at most risk are vegans who do not consume any kind of meat or animal product. However, regular vegetarians are also at risk of developing vitamin B12 deficiency. Another study revealed that 92 percent of vegans and 67 percent of lacto-ovo vegetarians suffer from B12 deficiency.

Two Interesting Microwave Facts

Microwaves convert Vitamin B12 to an inactive form, which means about 30-40% of the Vitamin B12 in microwaved foods is not usable by mammals. On the other hand, spinach loses about 77% of its folate when cooked in a normal stove, but retains nearly all of it when cooked in a microwave. In the same way, steamed vegetables, as a rule, tend to retain more of their nutrients in a microwave than when cooked in a traditional oven.

Energy Drinks Unmasked

A friend of mine, Jeff wondered what is in energy drinks that makes them work and are they safe. That sent me scouring my personal stash and the web for answers. The following excludes the larger volume drinks, such as Monster, Red Bull, etc., and offerings from Pepsi, Coke, and others. Those all have their own host of reasons to avoid, but that is for another discussion.

Most of the two ounce shot energy drinks contain varying amounts of taurine, caffeine, sucralose (splenda), niacin, vitamin B12, B6, folic acid, sodium, acai fruit extract, guarana, and many other ingredients that are almost impossible to spell or pronounce. Others have green tea, L-carnitine, ginseng, yohimbine, and all contain water and natural and artificial ingredients (whatever that means). Most have zero calories listed. Many have warning not to take more than one every four or six hours (likely in self defense from the FDA).

Many are described as an energy shot to enhance concentration and improve performance. They do not specify what performance. A number of them are designed specifically for hangover relief, and a few diet suppression. The only difference I could find in these ingredients was more vitamin B12 (in one type 10,000% of the daily value). Some of the names are 'pure energy, 5-hour energy', 'eternal energy, 'extra energy', 'Extra strength energy', 'java-mite', 'XX Energy', 'high energy', 'hangover recovery, 'diet aid', etc.

The majority of the dozen I checked come in little white two ounce bottles covered with shrink wrap covers. Interesting that so many have the identical bottle (with the exception of the bottom indents) and wrapper type regardless of manufacturer. Could find no common denominator other than that. Prices ranged from as low as $.88 to $3.98 for the same size. Interesting to note that one of the most popular and most expensive, 5 hour energy has the least liquid at 1.93 ounces.

Most sites agreed the biggest reason for the jolt is the large amount of caffeine, about as much as two cups of coffee in a small two ounce dose. Studies show they are no better as a pickup than coffee, although they are concentrated in less liquid as well as more convenient and quicker to drink. Annual revenues for energy drinks is about 13 billion dollars.

Bottom line, the caffeine is the kicker, the vitamins go out in the urine, the other ingredients are for flavor, preservatives, and color. None have proven to be bad for us, probably due to the trace amounts contained. None are good for children for the same reasons as coffee. In spite of a few rantings by the usual fear mongers, these have yet to be proven unsafe, with the exception of occasional jitters common to those who do not well tolerate caffeine. In my case, they seem to work as advertised and do not provide any physically noticeable high or low.
