An apple a day keeps the doctor away

Granny smith, gala, ambrosia… yummy. I’ve never really understood how people cannot like apples. They are so delicious, and can be eaten in such a nice variety of ways. Eat them right off the tree, put them in a salad, drown them in peanut butter, bake them in a pie, cover them in caramel… really, the list goes on and on. But besides the fact of being delicious, there are other reasons why I love this fruit.

Varieties of Apples

The saying “an apple a day keeps the doctor away” definitely holds some truth to it. There are many health benefits included in eating apples, and I’ll highlight a few of them. First of all, apples have been shown to be great for the heart. A recent study out of the University of Michigan found that rodents with identical diets, except for one also eating apples, had much different results with regards to blood pressure and overall heart function at the end of the study. The rodents who had apples added to their diets had lowered blood pressure, reduced cholesterol and also reduced oxidative stress.

Another reason to eat apples is to help with the prevention of cancer. The American Institute for Cancer Research shows that from eating one apple, we receive 10 percent of our needed daily intake of fiber and vitamin C. From these specific nutrients, we help reduce the risk of getting such colon and esophageal cancers. They also mention that apples have phytochemicals, which play a role in cancer prevention. Phytochemicals are chemicals which benefit are health, but are not ranked high enough to be considered essential.

These are only a few of the perks when including apples in our diets. Don’t enjoy eating them raw? As I said earlier, this scrumptious fruit can be served in a variety of ways, such as hot apple cider, apple sauce, or  apple muffins.

Eat an apple a day– don’t delay!

Is Cholesterol Good or Bad?

With the recent trends in the 21st century, people are more concerned and becoming more knowledgeable of the risks with elevated levels of cholesterol. Many people when hear about cholesterol immediately relate it with heart problems however cholesterol has many prominent functions in the body.

Cholesterol, a waxy steroid fat, plays an important role in various systems in the human body. Cholesterol has many functions; it helps in maintaining membrane flow and permeability. It is the basis for synthesizing bile acid, which help to digest food in the intestine. Additionally cholesterol is the precursor for Vitamin D synthesis as well as steroid based hormones such as estrogen and testosterone. Cholesterol is also a constituent of myelin sheath that surround nerve fibres to help speed up the rate of signal transduction between nerves. Thus it is crucial to mental function.

Liver makes approximately 85% of cholesterol and only 15% is provided through diet. Cholesterol cannot travel by itself in the body since it does not dissolve in the bloodstream therefore it is transported via lipoproteins. There are two major types of lipoproteins, low density lipoprotein (LDL) and high density lipoprotein (HDL). LDL cholesterol is commonly believed to be the ‘bad’ cholesterol as it takes the cholesterol that is produced by the liver to feed the tissues. High level of LDL cholesterol can cause atherosclerosis, which is a hardening of the arteries due to cholesterol build up, and thus plaque formation. HDL cholesterol reduces cholesterol by transporting excess cholesterol from tissues to the liver for elimination from the body.

How can we control our cholesterol level?

Life style changes are one of the first methods for reducing cholesterol levels. Exercising and maintaining a healthy diet can help to reduce LDL.

An interesting food product that is commonly found in households that helps reduce cholesterol is honey! Honey has found to reduce total cholesterol level. It contain antioxidant the prevent cholesterol form coming out of the cells and into the arteries thus reducing LDL cholesterol. Increasing dietary fibres also reduce total LDL by binding to bile acid and carry them outside the body, promoting the liver to convert more cholesterol to bile acid. In addition to natural solution to lower cholesterol levels medications such as statins is recommended which is very effective in preventing cardiovascular disease.
