Calcium is one of the most abundant resources in the body and plays a vital role in our bodies. A daily dose of calcium is needed to strengthen our bones, teeth and other areas such as the sarcoplasmic reticulum which is directly responsible for the release of calcium during muscle contraction and absorption during relaxation. Higher Ca2+ release in the sarcoplasmic reticulum and helps in contributing the overall effectiveness of the cardiac muscle. This is done through daily intake of calcium which helps maintain the blood pressure, strengthens the contraction of the heart muscle and prevents obesity.

Since calcium is not made inside our bodies, they are derived from external sources such as milk, which is known to provide calcium to our body. The main storage unit for the sarcoplasmic reticulum is the cardiac myocytes (Picht et al., 2011). The contraction of the sarcoplasmic reticulum allows the release of more calcium which can therefore be pumped into the blood stream. This calcium supplementation reduces the systolic and diastolic blood pressure which in return helps in lowering and maintaining the blood pressure, preventing hypertension and other damages to the heart (Marks, 2003). …show more content…

Caffeine present in the cup of coffee has a direct impact on the release of Ca2+ from the sarcoplasmic reticulum. A daily dose of caffeine increases the Ca2+ concentration in the sarcoplasmic reticulum to a certain extent, which in turn strengthens the contraction of the heart muscle (Klein et al., 1990). This allows the heart to do the same amount of work without working as hard as it usually

Calcium regulation is critical for normal cell function, neural transmission, membrane stability, bone structure, and intracellular signaling. Calcium is required for the normal blood clotting by activating the release of thromboplastin from the blood platelets. Approximately 40% of calcium is in the ionized form. Ionized

With this being said, the author includes this in his essay because he wants to show that it is possible to go without caffeine, but people consume caffeinated drinks in order to feel awake, alert, and focused. In addition, Gladwell includes scientific information about how caffeine works in humans’ bodies. He does this to show that caffeine has a healthy and safe effect on one’s body, and because of this, “caffeine is such a wonderful stimulant” (250). Therefore, Gladwell effectively incorporates historical figures and scientific knowledge in his essay in order to give strong evidence, and it would be difficult for people to argue against why caffeine has a beneficial impact on

Preventing Osteoporosis, Adult Osteoporosis is a condition that causes the bones to get weaker. With osteoporosis, the bones become thinner, and the normal spaces in bone tissue become larger. This can make the bones weak and cause them to break more easily. People who have osteoporosis are more likely to break their wrist, spine, or hip. Even a minor accident or injury can be enough to break weak bones.

Reaction time, coordination, and performance in heat are also affected after the ingestion of caffeine. A recent study on the effect of caffeine on athlete’s performance in heat showed that athletes that ingested caffeine before running in high temperatures completed 15-23% more work than those who used water or another widely used sports drink. Caffeine can also help athletes recover after a sporting event, when used with carbohydrates. Research shows that drinking a beverage with both caffeine and carbohydrates in it rebuilds glycogen 66% faster than a regular drink with only

Wolves in the wild hunt large animals such as bison and deer, through this prey they obtain most of their required essential vitamins. (Wildlife, 1994) Calcium is one of their required minerals that they obtain from the bones of their prey, this is neglected in their captive diet as whole prey is not given to the wolves, so they lack the sufficient amount of bones. Instead they are given calcium supplements in the form of formulated biscuits and shanks of deer. (Zoo, 2014)

How you ask? Milk acidifies the bodies pH and triggers biological correction. Calcium is an acid neutralizer; the biggest storage area for calcium is in our bones so when we drink milk we use calcium to neutralize the acidifying effect. Since the calcium is pulled from our bones it has to leave the body via our urine which actually leaves us with a calcium deficit. Interestingly enough studies are stating that people who drink more milk actually experience more fractures and broken bones than those who do not consume milk products.

Caffeine is a chemical found naturally in few plants all over the world. From these plants it is processed into its pure form and then put into other things such as soda, energy drinks, tea, and pills. Energy drinks and soda are some of the most widely marketed products in the world, even though they contain the highest concentration of caffeine outside of pure caffeine supplements. It is a stimulant that affects everyone in strange but semi predictable ways. Research has been done on this topic since the 1920’s and many different conclusions have been reached.

It is true that Calcium is essential for the body. However, is the milk the best source for calcium? [let’s find out] Amy Lanou Ph.D., nutrition director for the Physicians Committee for Responsible Medicine in Washington, D.C., states that: “The countries with the highest rates of osteoporosis are the ones where people drink the most milk” In fact, milk decreases the pH of the body which cause the calcium to leave the bones to neutralize the acidifying effect of milk, which will eventually cause calcium deficit. 2.

Whenever a consumer uses an energy drink a series of effects begin in his/her body. The organism receives an instant boost as the caffeine successfully manages to block the duties of the adenosine, a chemical located in the brain whose function is involved with sleeping. After the completion of the process caffeine forces part of the neurons in the brain to lighten up, which later on causes the body to release the hormone adrenaline. When the hormone is active it forces the liver to provide the bloodstream with additional

Contrary to what many people think, drinking coffee is not associated with an increased risk of heart disease. In fact, drinking coffee does the exact opposite; it decreases the risk of contracting heart disease. One study in Japan showed that drinking at least 1 cup of coffee on a daily basis reduced the risk of dying from heart disease by 38% in men. Yet another research carried out by Harvard School of Public Health in conjunction with Beth Israel Deaconess Medical Center concluded that drinking at least 4 cups of coffee daily reduced the risk of heart failure by 11%. Studies have also shown that drinking coffee can help minimize the risk of arteries being
