Smorgasbord Health Column – Food Therapy – Olive Oil…keeps your body moving by Sally Cronin

As a follow on from the recent series on the Weekly Grocery Shopping List of foods that contain the nutrients the body needs that contain the nutrients the body needs I am going to repeat my series from 2017 on the health benefits of some of our most common foods.

Food therapy is a broad term for the benefits to the body of a healthy, varied and nutritional diet of fresh foods.

Most of us walk through the fresh produce departments of our supermarkets without really paying much attention to the individual fruits and vegetables. This is a great pity because the vast majority of these foods have been cultivated for thousands of years, not only for their nutritional value but also for their medicinal properties. If you eat a healthy diet you are effectively practicing preventative medicine. A robust immune system, not only attacks external opportunistic pathogens, but also works to prevent rogue cells in the body from developing into serious disease.

NOTE – If you are on any prescribed medication do not take yourself off it without consultation with your doctor. If you follow a healthy eating programme and lose weight and are exercising you may not need the same dose and with your doctor’s agreement you may be able to reduce or come off the medication all together.

This week the food in question is Olive Oil. It stands in the shade next to my hob and is used a number of times a day on our breakfast (blitzed fresh tomato, red pepper, garlic and pimiento with a drizzle of olive oil), over my cooked vegetables and salad and also to prepare cooked meals.

Here are the health benefits of this versatile and very healthy fat.

For many years fats were considered to be the baddy in the diet and recently it was interesting to see that for the vast majority of the population the difference between healthy and unhealthy fats was still a mystery despite all the health campaigns.

The right fats are essential for nearly all our bodily functions and they provide a massive amount of nutrients that play a vital role in the processes going on in our body 24 hours a day.

Lo and behold the ‘experts’ have now retracted their ill founded advice about dropping all fats and replacing with carbohydrates and low fat options in favour of a higher fat diet.. provided those fats are not trans fats in industrially produced foods.

Having said that, you cannot eat pounds of any fats, however healthy, without combining it with a balanced diet of vegetables, fruit, wholegrains, protein and exercise…

My favourite fat is olive oil and it is amazing how many health benefits there are in a tablespoon. Including this healthy fat in your diet on a daily basis in moderation provides the right fats needed by your body to function healthily and efficiently.

Essential Fatty Acids (EFAs) are necessary fats that humans cannot synthesise and must be obtained through diet. There are two families of EFAs Omega-3 and Omega-6. Omega-9 is necessary but non- essential as the body can make it if the other two fatty acids are present.

EFAs are essential because they support our cardiovascular, reproductive, immune and nervous systems. We need these fats to manufacture and repair cells, maintain hormone levels and expel waste from the body. They are part of the process that regulates blood pressure, blood clotting, fertility and conception – and they also help regulate inflammation and stimulate the body to fight infection.

Omega-3 (Linolenic Acid) is the principal Omega-3 fatty acid and is used in the formation of cell walls, improving circulation and oxygen. A deficiency can lead to decreased immune system function; elevated levels of LDL (bad cholesterol) high blood pressure and irregular heartbeat.

Omega-6 (Linoleic Acid) is the primary Omega-6 fatty acid. Omega-6 can improve rheumatoid arthritis, PMS, skin problems such as eczema and psoriasis.

There is growing evidence that the non-essential Oleic acid, Omega‑9, may help to lower cholesterol by decreasing the unhealthy cholesterol, LDL (low-density lipoprotein), while at the same time raising the level of healthy cholesterol, HDL (high density lipoprotein).

Oleic acid is also emerging as a regulator of blood-sugar levels and as a possible protection against breast and prostate cancer. So, including half an avocado in your diet every day may well protect you from the harmful long-term effects of a number of diseases.

Olive oil is also an excellent source of Vitamin E and phenols.

Vitamin E: Tocopherol; As an antioxidant it protects cell membranes and other fat-soluble parts of the body such as LDL cholesterol from oxidative damage and blood vessels. It can be used topically for skin health and is involved in the reproductive system. It may help prevent circulatory problems that lead to heart disease and Alzheimer’s disease by preventing clots from forming. It improves the pulmonary function of the lungs and enhances the white blood cells ability to resist infection.

Phenols: are a large group of compounds that include flavonoids such as anthocyanin and quercetin, phenolic acids like ellagic acid, fibres such as lignans and vitamins. Many of these have antioxidant, anti-inflammatory and anti-clotting properties, all of which are known to benefit cardiovascular health.

olive oilThe benefits of Olive Oil

Extra virgin olive oil which is from the first pressing of the olives is the best oil to use as it contains higher levels of nutrients, particularly Vitamin E and phenols above. Recent research into the reasons why Olive oil extensively used in Mediterranean diets is so healthy has thrown up some interesting results.

In a human trial it was found that polyphenol- rich olive oil included in the diet improved the health of blood vessels which was not the case for another group of volunteers that included oil in their diet with the phenols removed. Obviously the healthier the blood vessels the more effective the entire circulatory system. It appears that the particular part of the blood vessel that is affected is the endothelium or inner lining of the blood vessels. The endothelium determines the interactions between the blood vessels and the immune, coagulation and endocrine systems. If the endothelium is not functioning correctly it can lead to calcification within the arteries and increased risk of heart disease and strokes. Another function of the endothelium is the release of vasodilators (increasing size of blood vessel) such as Nitric Oxide and vasoconstrictors (decreasing size of blood vessels) such as thromboxane and prostaglandin. Like any system in the body balance or homeostasis is required to ensure that blood pressure is regulated and the phenols in olive oil ensure that sufficient nitric oxide is produced to keep the arteries open and blood flowing.

 

Other research areas

Until now it has been difficult to isolate which component of this very nutrient rich oil was responsible for the health of Mediterranean populations. Recently however in America they have identified a previously unknown chemical that they have called oleocanthal that appears to have an extremely effective anti-inflammatory action. They have compared it favourably with over the counter pain relievers for inflammatory conditions such as ibuprofen. This is great news for sufferers of inflammatory diseases such as arthritis.

Other Benefits

Olive oil is very well tolerated by the digestive system and is therefore beneficial for stomach ulcers and gastritis. The oil activates the secretion of bile and pancreatic hormones much more effectively than prescribed medication and therefore lowers the incidence of gallstone formation.

Two tablespoons of a day has been shown to lower oxidation of LDL (lousy cholesterol) in the blood whilst raising antioxidant levels such as Vitamin E.

It is suggested that including olive oil in your diet may also help prevent colon cancer and this provides an alternative to patients who are vegetarian and do not wish to include fish oils in their diet.

Including extra virgin olive oil every day in your diet is likely to protect you from diseases such as atherosclerosis, diabetes, asthma, breast cancer and arthritis.

The best oil to buy

As I have always said the less processed a food is the better and olive oil is no exception. On the shelf you will find at least four different grades of oil.

Extra Virgin which is the best, least processed and most nutritional and comes from the first pressing. This should be your first choice and used for all cooking and dressings during your detox period.

Virgin is from the second pressing and should be your second choice.

Pure undergoes some processing such as filtering and refining and is a lesser grade oil.

Extra Light – has undergone considerable processing and only retains a small amount of nutrients or even olive taste. It is not officially classified as an olive oil and it was produced more for the “diet” culture than for taste or nutrition.

Storing Olive Oil

Olive oil degrades in light and should be kept cook and tightly sealed. If it is exposed to air oxygen will turn it rancid. It is also better kept in a cupboard away from natural light and the best containers are ceramic jugs rather than glass or plastic bottles.

  3. As sinful as this will sound, thee recipes come to mind on Olive oil – ‘Brazillian” shrimp, a pork chop ecstasy and one is like to try eventually, Spanish tortilla. Brazilian shrimp is just garlic shrimp tapas but ding ding dusted it in ground cinnamon as I couldn’t see the label…. A pork chop ecstacy is olive oil and butter to fry a gently salted pork chop… The butter allowing the olive oil to better be at 350f for a gorgeous treat, and before I’m done exploring foods, I want to try a Spanish tortilla which involves a lot oil gently boiling in oil potato… Or America’s test kitchen a more sensible usage of oil…

    • Thanks for your suggestions.. Carol Taylor who writes our food column uses it liberally and having lived in Spain 17 years nearly every dish we ate was generously doused in olive oil.. including tortillas..we still do it today on cooked and salad meals. Genius with the cinnamon on the shrimp..unfortunately we cannot get the big guys here, certainly not as cheaply in the US.. and none of it sounds sinful.. just fresh food cooked with taste…

  4. We use olive oil a lot in my house. We always buy extra virgin, too, and try to get it from a named country (preferably Spain or Italy) because we prefer the taste. I enjoy it with fresh (preferably home made) bread dipped in it.
