The Queensland Davidson Plum

Todays’ post is about the Queensland Davidson Plum. We have just spent a week holidaying in Cairns and this fruit makes a regular appearance on restaurant menus.

 I didn’t know a lot about this native fruit, which is considered highly nutritious. I have done some research and here is what I found.

 The Davidson plum is an Australian Native food with it’s earliest known mention by ‘The Gardeners Chronicle’ in 1876.

 There are several species of Davidson Plum, naturally growing from far-northern New South Wales to tropical north Queensland.

The species found mainly in N.S.W is Davidsonia jerseyana and is classified as endangered. The Davidson plum commonly found in Queensland, Davidsonia pruriens, is not.

More about the Qld variety

This species of rainforest tree naturally grows in the coastal and upland rainforests of northeast Queensland. The species is also grown commercially in mid-north coastal areas of New South Wales and on the Atherton Tableland in north Queensland. The Queensland Davidson’s plum, is a taller tree than the other species, reaching up to 12 metres high.

 Its fruit is larger, firmer and generally grows on the upper branches of the fruit tree, rather than along the trunk. The fruit superficially resembles the European plum and contains 2 flat fibrous seeds.

 Davidson plums are not often eaten as fresh fruit due to the intense fruit acid and low sugar content. This gives them a sour taste with a slight bitterness.

 All the health benefits

 The flavour of the fresh fruit may not be popular, however the fruit has other properties that have contributed to its demand.

 The deep, dark purple fruit with blood red flesh contains high levels of anthocyanins, natural pigments that are strong antioxidants. An antioxidant powerhouse, the plum has levels higher than the blueberry, which is renowned worldwide as the ‘health-promoting fruit’.

 Antioxidants hold a number of benefits for human health, potentially preventing and delaying diseases such as Alzheimer’s disease, autoimmune and cardiovascular disease, cancer, and diabetes.

 The substantial amount of antioxidants means you only need to consume small amounts and still receive the equivalent nutritional benefits compared to other fruit and vegetables.

 The Davidson plum also contains very high levels of potassium. Potassium helps our muscles move, our nerves work and our kidneys filter out toxins. It also plays a vital role in our metabolism.

A good source of Vitamin C, almost 100 times the amount found in oranges.

They are also a unique dairy-free source of calcium and contain significantly more lutein than an avocado (thought to be the primary source of lutein). Lutein is a carotenoid vitamin that plays an important role in eye health.

 The skin of the Davidson plum contains the majority of the nutrients, so it is recommended to consume the fruit in full for all the benefits.

 Food uses

 Davidson plums are usually combined with other ingredients to balance out their intense, tart flavour. The intense burgundy colour of the plum can act as a natural food colorant giving it many uses in food manufacturing industries.

 As a fresh fruit they are used in a range of sweet and savoury preparations. Davidson plums can be cooked down to make sauces, preserves, chutneys, and pie fillings. They can be macerated or pressed to make marinades, glazes, and dressings. Additionally, they are used to make juice, wine, liqueurs, and cordials.

 For convenience, many health food companies are freeze-drying or air drying the fruit and creating powders that can be added to numerous recipes and dishes. These bright powders have been used on cooking shows like Masterchef.

 Studies are also being conducted on the Davidson Plum’s antimicrobial properties, which are thought to act as a natural food preservative.

However you try this amazing fruit, it definitely has some great benefits for our health.

Is Vitamin P a recognised vitamin?

Todays post is about Vitamin P. I came across the reference to Vitamin P while writing my last post about Buckwheat. 

It is something that isn’t mentioned often, so I thought it would be a good topic to look at.

What is Vitamin P?

It turns out that vitamin P is not actually a recognised ‘vitamin’.

It is actually a term that was used to name a group of plant compounds called flavonoids. When first discovered by scientists in 1930, they were thought to be a new type of vitamin and, therefore, named vitamin P. This name is no longer used, as it was determined that flavonoids are not vitamins.

The actual word ‘Vitamin’ comes from the Latin word ‘vita’ meaning ‘life’. It was originally thought that vitamins contained the essential building blocks of life and in the early 1900s the word was ‘vitamine’. Eventually, as scientific understanding of these substances advanced, the word was changed to vitamin.

Though flavonoids have been found to be extremely beneficial, they are however not ‘vital for life’.

There are several types of flavonoids found in fruits, vegetables, tea, cocoa, and wine. They give certain foods their colour; provide plants with protection from ultraviolet (UV) rays and infection. There are currently over 6,000 known flavonoids.

The term ‘vitamin P’ is now more commonly used in reference to Rutin, one of the most important and well-researched flavonoids. This citrus flavonoid, like all flavonoids, is an antioxidant.

More about Rutin

The name ‘rutin’ comes from the plant Ruta graveolens, which also contains rutin.

Rutin or rutoside, is a highly bioavailable flavonoid, found in the pigments of several plants, such as passionflower and tea. It is also widely distributed in vegetables, fruits, and medicinal herbs such as asparagus, apples and buckwheat. Further, buckwheat is considered to be one of the best dietary sources of rutin.

What are the health benefits?

Rutin is firstly a flavonoid, which are well known for their antioxidant properties.

However, scientists have found that rutin has various pharmacological properties with several uses in different traditional and complementary medicines.

Specific parts of its molecule interact with different systems in the body, such as the brain, heart, or blood vessels. This means it has numerous beneficial effects.

Studies found that rutin also enhances the action of Vitamin C, supports blood circulation, helps alleviate allergies, viruses, or arthritis and other inflammatory conditions.

Rutin promotes collagen production; helps strengthen blood vessels and improve circulation.

It is useful for treating conditions affecting vessels, such as hemorrhoids, varicose veins, and spider veins.

In addition, some research suggests that rutin may prevent the formation of blood clots that could help prevent heart disease and stroke.

It has been found to be antibacterial, anti-protozoal, anti tumour, anti-inflammatory, anti-allergic, antiviral, antispasmodic, and antihypertensive, just to name a few.

With this information in mind, it seems like a good idea to boost your rutin intake every day. The easiest way to do this is by eating buckwheat, unpeeled apples, figs, or asparagus.

 Till the next post,

A bit about Buckwheat

Todays post is about Buckwheat. After sharing my Digestive Biscuit recipe and the reference to buckwheat being good for digestion, I thought that this topic should be next.

So, what is buckwheat?

The buckwheat plant was domesticated in north western China 3,000 years ago and despite the name, is not related to wheat in any way. Instead, buckwheat is actually related to sorrel, knotweed, and rhubarb. Its seeds so closely resemble the much larger seeds of the beech tree that the plant has been called “beech wheat,” or buckwheat. It is actually a soft leaf, green plant with pretty white flowers.

Buckwheat is not classified as a ‘true’ grain, but rather a ‘pseudo-cereal’. Its nutritional profile, nutty flavour, appearance and culinary applications have led it to be commonly referred to as a grain.

It has many Health Benefits
  • It’s gluten free
  • High in protein (13-15%), second highest only to oats, and rich in the amino acid lysine.
  • Rich in polyunsaturated essential fatty acids, such as linoleic acid.
  • Contains vitamins B1, C, E and P as well as high levels of zinc, copper, and manganese.
  • High in soluble fibre.
  • A rich source of antioxidant compounds.
  • Contains rutin, a bioflavonoid that helps control blood pressure.
Beneficial to the Cardiovascular System

Diets that contain buckwheat have been linked to lowered risk of developing high cholesterol and high blood pressure. The beneficial effects are due in part to its rich supply of flavonoids, particularly rutin.

Rutin protects against disease by extending the action of vitamin C and acting as antioxidants. This helps maintain blood flow and keep platelets from clotting excessively.

It’s also a good source of magnesium. Magnesium relaxes blood vessels, improving blood flow and nutrient delivery while lowering blood pressure—the perfect combination for a healthy cardiovascular system.

Supports digestive health

Buckwheat has high content of fibre, about six grams in every one cup serving. The fibre helps to fill you up, suppresses the appetite and lowers the chances of over eating. It also helps move food through the digestive tract. This type of insoluble fibrous food is essential for cleaning and strengthening intestines.

Buckwheat is also one of the foods to eat to heal and seal a leaky gut. This is because it is the world’s best source of vitamin P. It actually helps to increase collagen formation and increase intestinal resilience.

Main forms of buckwheat

As flour – it may be used to make gluten free crepes and pancakes. It is also used in conjunction with other flours to make muffins, rolls, bread and cookies. Also works well as a thickener for sauces, soups and casseroles.

Buckwheat groats – are dehulled buckwheat kernels. The groats are used in many dishes throughout the world. In Europe the toasted groats (Kasha) are used in dishes like pilafs.

Soba noodles – buckwheat flour is mixed with wheat flour to produce these Japanese noodles. The buckwheat flour content can range from 50% to 80% depending on the type of noodle produced.

With so many health benefits, it seems like a good idea to include buckwheat as a regular part of our diet.
