This One is On the Science Side..
Vitamin D is potentially more important to your bones than calcium. This is because it brings the calcium to your bones, and tells your body how much calcium to carry through your blood. Without Vitamin D, your body won't use your calcium. Currently the recommended amount is 400 IU/day. This is very controversial, and will most likely be raised by at least a thousand in the next year.
There are also several different forms of calcium. Two of the most popular are Calcium Carbonate and Calcium Citrate (read the back of your supplement label, it will tell you unless it's a raw food source). Calcium Citrate is the one you want to look for, because you will absorb much more of it!

Recommended amounts | Vitamin D AI Adults 19-50yrs : 5 ug/day Adults 50-70yrs : 10 ug/day Adults over 70yrs : 15 ug/day (1 ug = 40 IU) | |||
Deficiency symptoms | Drowsiness, depression | Loss of bone mass | Rickets, Osteomalacia (“soft bones”), Osteoporosis | |
Biochemical/ physiological cause of deficiency symptoms | The biosynthesis of enzymes for the nervous system, synthesis of nitric oxide synthase, and increased glutathione levels are how vitamin D affects brain function | Vitamin D regulates blood calcium levels, directly affecting the amount of calcium the bones can receive. If there is less calcium being absorbed, there is less bone mass altogether. | Vitamin D increases the absorption of calcium from foods, and reduces calcium loss in urine. This keeps calcium in the body, which spares the calcium that is stored in bones. | |

Ok everyone, here it goes! Let me know what you think, I take feedback seriously.
Some History and Some Science!
The first artificial sweetener was known as cyclamate, which was used in medicines and soft drinks in the 1960s. It is about 30 to 50 times sweeter than normal table sugar. Cyclamate was banned by the Food and Drug Administration (FDA) in 1969 because studies had shown that it might have caused cancer in rats during lab tests. The FDA decided Cyclamate was then unfit for human consumption. Cyclamate was pulled off the market shortly after it was released.
The next artificial sweetener developed was known as Saccharine, which we know as Sweet N' Low. This sweetener gained popularity when it was used in the soft drink, Tab. The FDA proposed a ban on the sweetener, complying with the {Delaney Amendment}, which required them to ban any food product that may cause cancer. The public was not happy about this. Articles were published that claimed the animals that were tested on were fed incredible amounts of Saccharine. It would take a human 1,250 twelve-ounce diet beverages a day over a lifetime to equal what was given to the animals. That equal to over 4,000 packets of saccharine a day, for a person's lifetime. This left Saccharine on the market, and it is still doing well in sales today.
Aspartame is another sweetener that is commonly found in many diabetic products, we also know it as Equal or NutraSweet. When this sweetener is broken down during digestion, it makes three different chemicals: aspartic acid, methanol and phenylalanine. Aspartic acid and phenylalanine are two amino acids (amino acids are the little pieces that make up a protein). Methanol, however, is converted into formic acid, which is another name for formaldehyde. Formic acid, in high concentrations, can become toxic. Some symptoms that have been reported from aspertame include, but are not limited to, dizziness, headaches, stomach discomfort, memory loss, nerve cell damage, reproductive disorders, migraines, mental confusion, brain lesions, blindness, joint pain, Alzheimer’s, bloating, nervous system disorders, hair loss, food cravings, weight gain... High levels of phenylalanine have also been linked to seizures, depression and schizophrenia. This is considered a low calorie sweetener because it is used in relatively small amounts because of how sweet it tastes. Aspartame cannot be used in cooking, because the chemical is not stable when heated. This does not include coffees or tea. The product currently generates $1.6 billion in sales.
If you've ever read the book, "Skinny Bitch", this is what they have to say about aspartame:
When aspartame was proposed to the Food and Drug Administration, it failed its initial test. It then failed the next seven attempts to be approved as an artificial sweetener. There was a grand jury proceeding against Searle for ‘knowingly misrepresenting findings and concealing material facts and making false statements in aspartame safety tests’, brought on by the FDA in an attempt to ban aspartame in 1977. During this proceeding, however, U.S. attorney leading the investigation against Searle was offered a job by the law firm that was representing Aspartame. Later that same year, the U.S. attorney resigned and withdrew from the case, delaying the grand jury’s investigation. The grand jury later had to drop the case due to the prolonged nature of it. The next two government attorneys that were entrusted to judge whether aspartame was safe for human consumption both ended up overruling scientific advisories and passing the sweetener anyway. They were both reported to have gone to Searle's law team as well.
Acesulfame potassium is another sweetener that is often blended with aspartame, and occasionally with other sweeteners. It is about as sweet aspartame, but has a bitter aftertaste (especially in high concentrations). This sweetener is very stable at high temperatures, so it can be used in cooking or baking. In the long run, however, it has been poorly tested and is generally deemed as a risky additive. It is absorbed from the digestive tract and excreted in the urine. This chemical remains intact during this process. This leads to wonder what happens in-between the process in your body.
Some other sweeteners are known as sugar alcohol sweeteners. Such sweeteners include, but are not limited to, xylitol, sorbitol, and erythritol. All of these sweeteners are metabolized, but are not fully absorbed by the small intestines. This results in them being low in calories, because the calories never have a chance to absorb into the body. They are sometimes used as laxatives in hospitals. Many sugar free candies or gums use these sweeteners as well, using lower amounts to so the sweetener will not have the laxative properties. They are also not used by the bacteria that causes tooth decay, so they are a good sweetener for toothpastes.
Sucralose, or Splenda, was approved by the Food and Drug Administration in 1998. Splenda is the highest selling sweetener on the market today. It is made by chlorine reacting with regular table sugar, which makes a new type of sugar. This new sugar cannot be broken down by your body, so it passes through without being absorbed. Splenda also uses a filler than cannot be digested, but does allow it to be used in baking. Splenda is known to be ninety-eight percent pure. The other two percent is made up of methanol and arsenic. Some symptoms reported from Sucralose are, but not limited to, diarrhea, organ damage, reproductive system damage, immune system damage, swelling of the liver and kidneys, and the decrease in body weight.
There have also been studies that suggest that other artificial sweeteners, such as high fructose corn syrup (and yes, I consider anything that has to be made in a lab artificial, no matter what the company that makes it claims), can stimulate weight gain by stimulating your appetite. A study released in 2008 had results that suggest high fructose corn syrup can block the uptake of Leptin in the brain. Leptin is a naturally occurring hormone in the human brain that tells the body when it is full, and to stop eating. If the body is not reading the Leptin, it may make it confusing for a person when it is time for them to stop eating. High fructose corn syrup contains approximately fifty percent fructose. Normal fruit consumption would not have the same results (or leptin resistance) as high fructose corn syrup. In lab studies, it took rats up to six months to develop the resistance. This suggests that a leptin resistance will develop over time, rather than immediately. There was also a study just released July 2009 that is looking at high levels of fructose causing memory loss.
This just goes with the old saying, too much of a good thing! Fructose is not a dangerous substance, but anything in excess is not good for your body. It is a complicated chemical machine that needs a balance of many different things. In today's world, it is very hard to avoid all artificial sweeteners. So, moderation is key! Don't stick with one specific kind. As you read above, each sweetener does different things in your body. Some are broken down to substances that can be harmful if they are given a chance to build up. Some aren't absorbed at all! So mix it up. Also try other more natural sweeteners, such as honey or agave nectar. Agave nectar also has a relatively low glycemic index, for those diabetic readers out there! There are also some very good ice cream recipes out there using agave nectar. You can buy it at your local store, or health food store (whole foods carries it, as does the Vitamin Shoppe). Honey is used by the body a little differently than regular table sugar, too, so stop stressing about the calories! It will be healthier for you in the long run than anything processed in a lab.
