The Health Benefits Of Mushooms

Photo: Getty
Today I will paraphrase an interesting health article I read in Life Extention - The Science of a Healthier Life - July/August 2024 ...

Mushrooms have an amino acid known as L-ergothioneine. Our bodies can't make it yet the compound is so essential to human health that our cell membranes have special transporters to deliver it into our cells.

In a 2021 population study, scientists noticed some interesting findings in people who ate mushrooms. Consumers who regularly ate one serving of mushrooms (a fungus) had a 16% lower risk of death. People who refrained from red meat and ate a serving of mushrooms daily had an astonishing 35% decrease in all-cause mortality. The scientists attribute the health benefits to one compound, namely this L-ergothioneine amino acid.

What's more, in observational studies, scientists connected L-ergothioneine to specific health benefits: L-ergothioneine may promote healthy aging by fighting oxidative stress and decreasing the rate of telomere shortening that inherently occurs as we age. Our eyes, brain, and red blood cells suffer the most from oxidation stress. These tissues have high concentrations of L-ergothioneine transporters which points to the important role the compound plays in protecting them. Telomeres are the protective caps on the ends of chromosomes, and unfortunately, they naturally shorten as we age.

L-ergothioneine also appears to act as a sunscreen for DNA, protecting against skin cancer and boosting DNA repair.

As it happens, L-ergothioneine and its transporter are present throughout the brain. Several studies have linked L-ergothioneine to preserving brain function in the areas of learning and memory. In a trial of adults, 5 mg of L-ergothioneine daily significantly improved brain function enough to make scientists take notice.

In the observational study, L-ergothioneine levels in the body were associated with better heart health lowering cardiovascular mortality by 21%. 

So in summary: Mushrooms contain a potent amino acid called L-ergothioneine. Scientists think it is responsible for many key health benefits: (1) combating oxidative stress, (2) slowing the rate of telomere shortening, (3) preserving cardiovascular health, as well as, (4) cognitive function, and (5) supporting DNA repair. In a population study, people who ate mushrooms bore these 5 benefits and lived longer than those who didn't eat mushrooms.
Mushrooms are rich in vitamin D and good sources of vitamins A, B6, and C. They also contain iron, phosphorus, copper, potassium, selenium, and fiber.

Finally here's my recipe for Salisbury Steak, a favorite, it has plenty of onions and those mega-healthy mushrooms. After writing today's blog, I'll be shopping for mushrooms. What about you?

Extra recipe: A simple way to sautรจ mushrooms as a side dish:

Ingredients: 

8 ounces mushrooms
2 tablespoons extra virgin olive oil
1 tablespoons wine
Photo: foodandwine
1 sprinkle of thyme
Salt and pepper to taste.

Directions:

1) Toss all the ingredients into a skillet and simmer on medium-low heat for about 10 minutes until all the liquid is gone.

I won't waste a bottle of wine just to remove 1 tablespoon. If I have no open wine, I flavor the mushrooms with soy sauce, dried rosemary, Cajun spice (instead of salt and pepper), and organic cider vinegar.  Feel free to spice as you like.

Beauty of Joseon Revive Eye Serum

What's a good treatment for crow's feet and fine lines around the eyes? The Korean beauty market has the answer with real science behind it, and it's not ultra-expensive.

 Beauty of Revive Joseon Eye Serum is created to treat wrinkles in the sensitive area around the eyes. It combines 10% ginseng root extract and retinal (like retinol, a vitamin A derivative) for its efficiency. Multiple studies show ginseng improves wrinkles because it contains a high level of saponins (ginsenosides -- plant compounds with a long history of use in traditional medicine). Retinal works 11 times faster than retinol. Although retinal has a higher exfoliation rate than retinol, Revive Eye Serum is formulated to work without irritation. The serum contains 2% stable retinal in the form of liposomes (a minute spherical sac of phospholipid molecules enclosing a water droplet).

Here's the science explained --

retinol -> retinal -> retinoic acid

Retinal converts into retinoic acid in one step while retinol takes 2 steps, but usually retinal is too harsh to use. However this eye cream uses retinal liposome that is stabilized by breaking the retinal into smaller parts and enclosing it in liposomes, as well as, adding more lipids (fatty acid molecules) and oils to it. It's also blended with beneficial glycerin, niacinamide (B3), and cholesterol to make the formula even more effective.

Unless you have sensitive under eye skin, a separate eye serum is a waste of money. But Revive Eye Serum is formulated to be gentle to use under your eyes and you could use it on your face. The serum is less than (not the same as cheap) many other face and eye serums for the strength and blend you're getting. Costs $11.50 - $15 for 1.01 ouncdepending on the seller

This is a stellar formula at a reasonable price to fight the crows' feet forming around your eyes!๐Ÿ‘€

Exfoliation In Skincare

The Ordinary has a wealth of skincare information on its website, as well as, inexpensive skincare products to help fight acne and the effects of aging along with helpful tips on how to keep skin healthy. One of the things I neglect to do is exfoliate my skin. I rarely do so, but multiple dermatologists recommend it as having a beneficial role in our skincare routines. So let's discuss exfoliation in today's blog. My source of knowledge begins with The Ordinary:

"Exfoliation is the process of removing dead skin cells from the surface layer of the skin. Physical exfoliation uses a product or tool to buff away dead skin cells," while "chemical exfoliation uses direct acids (AHAs and BHAs) which have the ability to weaken bonds between surface skin components, allowing the acids to slough away dead skin cells at the surface." Exfoliation helps to unclog pores, promote even tone and texture, and bring new skin cells to the surface.

AHAs are alpha hydroxy acids a/k/a fruit acids. BHAs are beta-hydroxy acids, which are also organic acids. Both act to dissolve the bonds that hold dead skin cells to the face. BHAs such as salicylic acid mildly loosen the glue that holds skin cells together. Salicylic acid is often in formulas targeting acne, rough, and bumpy skin.

Many dermatologists [like the creators of Doctorly] recommend chemical exfoliation over physical exfoliation because the tools we buy in retail shops are subpar to what dermatologists use in their offices, plus we lack the medical training to use them like doctors. Physical exfoliation can therefore do more damage to the skin, making chemical exfoliation safer, an awareness that may surprise you! Scrubbing gloves, cleansing brushes, exfoliation salts, and home microdermabrasion devices can be too abrasive harming instead of helping our skin, or in the case of devices just not strong enough to be effective. Also, the gloves and brushes might become a breeding ground for bacteria.

The Ordinary’s Direct Acid family offers both AHAs and BHAs of varying strengths and formats making it simple to find the right one for you. You will rarely find a cheaper, backed-by-science brand. Here are 5 choices:

1) Glycolic Acid 7% Toning Solution - An exfoliating toner for targeting dullness, texture, and signs of aging.

2) Latic Acid 5% + HA
A milder exfoliator that works to reveal smoother skin. (A stronger strength is available.)

3) Mandelic Acid 10% + HA - A leave-on serum that helps improve skin clarity, balance uneven skin tone, and correct skin texture gently yet effectively.

4) Salicylic Acid 2% Anhydrous Solution - A gentler water-free solution for blemish-prone skin and uneven texture. (A stronger strength is available.)

5) AHA 30% + BHA 2% Peeling Solution - An advanced-level exfoliating peel.

So now we know a bit more about the role of exfoliation in skincare, plus several types and strengths offered by a super affordable brand! The next step is to put our knowledge into practice.๐Ÿ˜‰ Because readers, I'm not perfect either.

Know The Minimalist Skincare

Photo: Minimalist
A savvy shopper needs to have a selection of brands to get the best value on skincare. Feel free to enter the words "skincare," "serum," and "anti-aging" in the blog's search box on the upper left to learn about some amazing brands that like today's featured line focus on efficacy, transparency, and affordability.

The Mininalist is a high-performance skincare brand with an array of cleansers, serums, moisturizers, and sunscreen based on science to address a range of skin concerns. The company was launched by 2 brothers (one a scientist, the other with a business background) in October 2020 to make low-cost skincare available in India because, at the time, The Ordinary (launched in August 2016) wasn't on shelves in India. Today both brands sell in both India and the USA, so everybody wins! The consumer has choices galore! Mohit Yadav is the CEO and co-founder with Unilever as an investor.

Although the Minimalist is not The Ordinary and The Ordinary is not the Mininalist, here's what they have in common: Clean packaging, transparent information, and ingredients that are scientifically formulated at rock-bottom prices -- all fantastic! While many consumers can get all their skincare needs met with products developed solely by The Ordinary or solely by the Minimalist, the Mininalist is especially good at offering a wide range of chemical peels and sun protection. If you have acne or rosacea, you'll have a greater selection of treatments from the Mininalist. An emphasis on treating acne explains why the Minimalist offers more chemical peels than The Ordinary. There's also better sunscreen at the Mininalist possibly because the company started in India, a continent where the population needs good sun protection.

The more knowledgeable you become about skincare ingredients and what you want your skincare to do, your appreciation for companies like the Mininalist and The Ordinary grows. Initially, it might seem confusing and like lots of work to learn about what ingredients to buy, but after you do the research to know, you know.

Moreover, sometimes the two companies pair or combine ingredients differently, and I think this also gives customers a greater chance to personalize their skincare. So for consumers, it's awesome to have not one, but two companies with stellar ingredients for less on the market! Hats off to The Ordinary for changing the skin suspension game, as well as, to the Mininalist for expanding it!

Skincare Holiday Gifts Everybody Will Love

Ho, ho, ho! Hard to believe the holiday season is here, isn't it? Let's consider the beauty mavens on your shopping list. A good skincare gift can be either an introduction to a stellar new brand or something extra for a friend who already has the knowledge and skincare basics. If your giftees use Retin-A or
its non-prescription derivative retinol (for nighttime), and perhaps vitamin C (in the mornings), they have an excellent anti-aging skincare routine even if they do nothing else. Other products may do good things for the skin, but they are less essential. Dermatologists call Retin-A or retinol the gold standard in anti-aging skincare. THE SAVVY SHOPPER has written a number of blogs explaining and recommending good retinol and you can use the search box to pull them up to read if you wish.

Today I'll feature skincare extras to give as holiday gifts that go beyond the basics. Sometimes it takes a friend's holiday gift to either introduce you to an unfamiliar brand or spoil you with ingredients you're not using -- the skincare extras - that provide additional skin benefits. They include:

1) The Ordinary Hyaluronic acid 2% + Vitamin B5 (see top image๐Ÿ‘†) - Hyaluronic acid moisturizes dry skin and Vitamin B5 helps the skin attract and maintain moisture. As we age our skin gets drier so keeping skin moist and dewy instantly makes us look younger ... and it feels better too.

2) The Ordinary Niacinamide (B3) 10% + Zinc 1% - Reinforces and balances the skin's protective barrier. Also treats acne by unclogging pores and drying oils and pimple-causing components.

3) The Ordinary Glycolic Acid 7% Toning Solution - Promotes mild exfoliation to correct dullness, uneven skin tone, or textual irregularities. Also contains skin-loving ingredients, such as Tasmanian pepperberry, aloe vera, and ginseng root to soothe, balance, and hydrate the skin. Amino acids are added to support the skin barrier. I'm surprised at how often YouTube dermatologists recommend glycolic acid + exfoliating the skin, a practice I rarely do. It speeds up skin turnover to promote new skin cells to rise to the surface.

The Ordinary is offering a 23% discount on their entire skincare line through December 23, 2022, on top of their already high quality and low prices.

The last two gift ideas are Korean skin barrier-protecting face creams. The Korean market excels at making beauty serums and creams. The following skin moisturizers will check Old Man Winter:
4) Etude House Soon Jung Hydro Barrier Cream - Is packed with lipids and fatty acids to strengthen and protect your skin barrier, including “Panthensoside”: Panthenol (Protection of skin barrier & maintenance of hydration) + Madecassoside (Soothing effect for irritated skin).

5) Pyunkang Yul Intensive Repair Cream - Contains ceramides, shea butter, macadamia seed oil, and antioxidants to protect the skin barrier and smooth the skin.

Extra find: Bakuchiol (a phytoretinol). A good one is IMGN Beyond Retinol๐ŸŽ„๐ŸŽ„๐ŸŽ„ 

This year make your beauty gifts count! Think quality, not quantity! Frequently beauty sets come with items nobody uses like bubble baths. Instead consider giving a skin elixir backed by science that really works, or an introduction to a fabulous beauty brand your friend or family member doesn't know about. A new discovery is exciting ... and how thoughtful of you to share your tips in the form of a gift!
