Alcohol and the body.

Todays post is about how our body, or more specifically the liver, deals with alcohol.

Many of us indulge in an alcoholic beverage on a regular basis. Some people indulge more regularly and in greater quantities than others. Most of us know the basics of what happens in our bodies when we drink alcohol.

Scott has recently covered this subject in his studies and I thought it was interesting. I decided to learn more details and share this information.

How the alcohol is initially absorbed.

Alcohol absorption begins in the stomach. However, it is absorbed much more rapidly in the small intestine due to the larger surface area. So, the longer the alcohol remains in the stomach, the slower the rise in the blood alcohol level. Fatty acids slow down the movement of food through the stomach. Therefore the consumption of foods higher in fats will slow the rise of blood alcohol. This will also give time for the enzyme alcohol dehydrogenase (ADH) to start breaking down the alcohol.

Alcohol dehydrogenase is our primary defence against alcohol, a toxic molecule that compromises the function of our nervous system. The high levels of alcohol dehydrogenase in our liver and stomach detoxify about one drink (10grams of alcohol) each hour.

Once the alcohol enters the blood stream, it goes directly from the digestive tract to the liver.

The science

In the liver there is more alcohol dehydrogenase to break down ethanol in the blood. The alcohol dehydrogenase breaks alcohol down into another compound, acetaldehyde. Next, another enzyme, called aldehyde dehydrogenase (ALDH) breaks it down further into acetate, another metabolite.

This can then be converted to Acetyl coenzyme A, (acetyl-CoA), an important molecule used in metabolic processes. It is primarily used by the body for energy production and is an essential component in balancing carbohydrate and fat metabolism

 What does this mean?

On those occasions when we consume alcoholic beverages while eating pizza and deep fried foods, followed by cake and ice cream, the body deals with the alcohol first.

This is because the liver recognises the alcohol as the most toxic substance in the body at the time.

So while the liver is dealing with the alcohol, the fats and sugars are getting pushed into the blood stream to wait. This also means that the liver will first break down the alcoholic beverage into its main components and then dealing with the alcohol first.

The liver requires certain essential nutrients from the body to do its job. It also works through the toxins in 2 phases. If there are not enough nutrients available for the liver to do its job, this causes the by-products to hang around for a lot longer in between the phases. This can then cause other issues.

 Supporting the liver

It is possible to provide support to the liver so that it can metabolise alcohol more effectively, therefore reducing long-term damage.

The 2 phases of detoxification require different nutrients.

Phase 1 requires B group vitamins, Folic acid, Glutathione, Antioxidants, Carotenoids, vitamins E and vitamin C.

Phase 2 requires Amino Acids (Glutamine, Glycine, Taurine & Cystine) and sulphurated phytochemicals found in garlic and cruciferous vegetables (broccoli, cauliflower, cabbage & Brussels sprouts)

There are also certain compounds available that may be helpful.

  • Grape seed extract is a well-known antioxidant that assists liver function.
  • Grapefruit seed extract increases gastric protection
  • Vitamin C
  • Zinc
  • Curcumin (found in Turmeric)

Current Australian health guidelines state “For healthy men and women, drinking no more than two standard drinks on any day reduces the lifetime risk of harm from alcohol-related disease or injury.” (NHMRC 2009) Sources – Principles of Anatomy & Physiology by Gerard J Totora/Bryan Derrickson, https://en.wikipedia.org, https://pdb101.rcsb.org

With this in mind, a good diet consisting of whole, unprocessed foods goes a long way in supporting the liver. Many of the nutrients essential for optimal liver function are found in fresh fruit and vegetables.

I hope you found this information interesting.

Good skin starts with our diet.

Today I’m writing about diet and the skin. Our skin is the human bodies largest organ.

Many people spend thousands of dollars trying to preserve it, especially on their face. However, few people consider that our diet shows on our face.

Beautiful skin starts with nourishment from within.

There are hundreds of steps involved in the cycle of skin renewal, of which the foods we eat are components. The body, skin included, is constantly under construction and it uses vitamins and nutrients from food to repair and rebuild, Older cells are constantly shed and replaced by younger ones and a steady supply of key nutrients is essential to support this rapid growth. Eating the correct balance of foods feeds our skin the vital nutrients it needs to help it stay soft, supple and blemish-free.

That said, as much as we may try to resist it, our skin does naturally age. Wrinkles and age spots are the inevitable result of time, but this ageing may be sped up by overexposure to the sun, strong soaps and chemicals, as well as poor nutrition. Excessive alcohol consumption and smoking both also age the skin.

 Start with simple changes.

By eating a variety of antioxidant-rich, fresh fruit and vegetables, healthy fats from oily fish and nuts, and a varied, balanced diet. This should give optimal levels of the nutrients that are crucial for radiant skin, including beta-carotene, vitamins C and E, zinc and selenium.

Fruit and vegetables contain powerful antioxidants that help to protect skin from the cellular damage caused by free radicals. Free radicals along with smoking, pollution and sunlight, can cause wrinkling and age spots. Beta-carotene, found in carrots, sweet potatoes and pumpkin, and lutein, found in kale, papaya and spinach are potent antioxidants, important for normal skin cell development and healthy tone.

 Just add water

Skin needs moisture to stay flexible. Even mild dehydration will cause it to look dry, tired and slightly grey. Water helps hydrate your body and leads to plump, healthy skin. Adequate hydration helps flush out toxins that can cause skin problems. It is also essential for skin metabolism and regeneration.

Drink plenty of water each day – all fluids count towards our daily allowance, but water is the best. We have all heard of the recommended 6 to 8 glasses a day. However, there is a simple scientific formula to work out how much water you need. Your weight in kilograms x .03 = daily requirement of water (e.g.; 60 x .03 = 1.8 litres).

Herbal, caffeine-free teas are good too. Some fruit and vegetables, such as watermelon and cucumber, also contribute fluids – the added benefit is that the minerals they contain will increase the rate you hydrate your body and skin.

Overall, promoting healthy skin with diet is all about adopting good nutritional habits.

So, while the Christmas season is a time of celebration with friends and family, it is also a time of food and drink. In order to put your best face forward for the new year, try to make good food choices.

Drink lots of water to counter act the effects of alcohol and remember to laugh.

To all my readers, thank you for your support and have a Merry Christmas.

I hope all my subscribers enjoy their Christmas recipe.

All about Oats, are they healthy?

Todays post is all about Oats.

With the cooler weather, many people turn to oats or porridge for breakfast. It has certainly become one of our favourites. There are also many differing opinions regarding how healthy this cereal is. I decided to do my own research and, as usual, share the results.

What are Oats?

The oat (Avena sativa), is a species of cereal grain grown for its seed, which is known by the same name. Oats have been around for a very long time. Researchers have found significant evidence that hunter-gatherers ate oats 25,000 years before the spread of farming.

In Scotland, oats became the staple grain. This is because oats are better suited than wheat to the country’s low temperatures and high humidity. As a result, the cereal grain is held in high esteem, as a mainstay of the national diet.

As a food, oats are most commonly rolled or crushed into oatmeal, or ground into fine oat flour. Oatmeal is chiefly eaten as porridge, but may also be used in a variety of baked goods, such as oatcakes, oatmeal cookies and oat bread. Oats are also a staple ingredient in cereals such as muesli and granola.

Oats are naturally free of gluten. They do however contain proteins called Avenins, which are similar to Gliadins from wheat. Avenins can trigger celiac disease in a small proportion of people. Other gluten-containing grains, mainly wheat and barley, also frequently contaminate oat products.

 Are oats really healthy?

They are generally considered healthy due to containing several essential nutrients.

A 100-gram serving provides 389 calories and is an excellent source of protein, dietary fibre, several B group vitamins and numerous minerals. Research has proven that the consumption of the whole grain, and oat-based products, significantly reduces total cholesterol concentrations.

Studies have also shown other possible health benefits of this cereal grain. These include reduced risk of coronary artery disease, lowering levels of cholesterol, and reduced risk of colorectal cancer.

A unique type of soluble fibre found in oats called beta-glucan, has numerous benefits. It nourishes and restores healthy gut bacteria and helps reduce blood sugar levels.

A few studies also indicate that oats may boost the immune system, enhancing the body’s ability to fight bacteria, viruses, fungi and parasites

Oats contain a range of molecules that act as antioxidants; this includes avenanthramides, which are polyphenols. Studies have revealed that Avenanthramides may play a role in keeping blood pressure low.

They also have anti-inflammatory and anti-itching properties when applied topically to the skin.

Using oats on the skin.

Oats contain zinc, which is an anti-inflammatory. They also contain compounds called saponins, which are natural cleansers. Oat extracts can also be used to soothe skin conditions, and their emollient properties are used in cosmetics.

It certainly seems that oats are good for us, inside and out.
