Health Benefits of Olives

Cardiovascular Benefits
When free radicals oxidize cholesterol, blood vessels are damaged and fat builds up in arteries, possibly leading to a heart attack. The antioxidant nutrients in black olives impede this oxidation of cholesterol, thereby helping to prevent heart disease. Olives do contain fat, but it’s the healthy monounsaturated kind, which has been found to shrink the risk of atherosclerosis and increase good cholesterol. When diets low in monounsaturated fat are altered to increase the monounsaturated fat content (without becoming too high in total fat), research study participants typically experience a decrease in their blood cholesterol, LDL cholesterol, and LDL:HDL ratio. All of these changes lower our risk of heart disease.
Recent research studies have also shown that the monounsaturated fat found in olives (and olive oil) can help to decrease blood pressure. The oleic acid found in olives–once absorbed up into the body and transported to our cells–can change signaling patterns at a cell membrane level (specifically, altering G-protein associated cascades). These changes at a cell membrane level result in decreased blood pressure.
Weight Loss
It appears that monounsaturated fats, the kind found in olives, when replacing saturated fats, may encourage weight loss. Olive oil consumption has been shown to breakdown fats inside fat cells, get rid of belly fat and reduce insulin insensitivity.
People who have the highest olive consumption eat fewer calories overall and are rarely overweight. Blood tests show they have higher levels of serotonin, a so-called satiety hormone that makes us feel full.
The aroma extracts from olive oil can leave us feeling fuller, cutting our calorie intake by almost 200 a day, they said.
Cancer Prevention
Olives protect cell membranes against diseases like cancer
Black olives are a great source of vitamin E, which has the brilliant ability to neutralize free radicals in body fat. Especially when working with the stable monounsaturated fats found in olives, vitamin E can make cellular processes safer. When such processes such as mitochondrial energy production are not well protected, the free radicals produced can cause oxidation, damaging a cell’s mitochondria, and preventing the cell from producing enough energy to supply its needs. If the DNA of a cell is damaged, it may well mutate and become cancerous. Studies have shown that a diet supplemented with olive oil leads to a lower risk of colon cancer, almost as low a risk as a diet rich in fish oil.
Less Allergies
New research may help explain how olives work to provide us with anti-inflammatory benefits, especially during circumstances involving allergy. Olive extracts have now been shown to function as anti-histamines at a cellular level. By blocking special histamine receptors (called H1 receptors), unique components in olive extracts may help to lessen a cell’s histamine response. Because histamine is a molecule that can get overproduced in allergy-related conditions and can be a key player in the inflammatory process, it’s likely that the anti-inflammatory benefits we get from olives involve this anti-histamine pathway. It’s also possible that olives may have a special role to play as part of an overall anti-allergenic diet. Your circulation will improve and you’ll be able to breath easier with olive consumption. They can increase blood flow and help lessen the effects of illnesses such as asthma through its anti-inflammatory properties.
Eye Health
One cup of olives contains ten percent of the daily recommended allowance of vitamin A which, when converted into the retinal form, is crucial for healthy eyes. It enables the eye to better distinguish between light and dark, thereby improving night vision. Furthermore, Vitamin A is believed effective against cataracts, macular degeneration, glaucoma and other age-related ocular diseases.
- Eating olives can improve the appearance of wrinkles by 20% since they contain oleic acid, which keeps skin soft and healthy.
- By eating just 10 olives before a meal, you can reduce your appetite by up to 20%. This is because the monounsaturated fatty acids contained in olives slow down the digestion process and stimulate the hormone cholecystokinin, a hormone that sends messages of fullness to the brain.
- Not only does it do that, but it also helps your body to stimulate the production of adiponectin, a chemical that burns fat for up to five hours after ingestion.
