A high daily dose of an omega-3 supplement may help slow the effects of aging by suppressing damage and boosting protection at the cellular level during and after a stressful event, new research suggests.

Researchers at The Ohio State University found that daily supplements that contained 2.5 grams of omega-3 polyunsaturated fatty acids, the highest dose tested, were the best at helping the body resist the damaging effects of stress.

Compared to the placebo group, participants taking omega-3 supplements produced less of the stress hormone cortisol and lower levels of a pro-inflammatory protein during a stressful event in the lab. And while levels of protective compounds sharply declined in the placebo group after the stressor, there were no such decreases detected in people taking omega-3s.

The supplements contributed to what the researchers call stress resilience: reduction of harm during stress and, after acute stress, sustained anti-inflammatory activity and protection of cell components that shrink as a consequence of aging.

The potential anti-aging effects were considered particularly striking because they occurred in people who were healthy but also sedentary, overweight and middle-aged – all characteristics that could lead to a higher risk for accelerated aging.

“The findings suggest that omega-3 supplementation is one relatively simple change people could make that could have a positive effect at breaking the chain between stress and negative health effects,” said Annelise Madison, lead author of the paper and a graduate student in clinical psychology at Ohio State.

The research is published today (Monday, April 19, 2021) in the journal Molecular Psychiatry.

Madison works in the lab of Janice Kiecolt-Glaser, professor of psychiatry and psychology and director of the Institute for Behavioral Medicine Research at Ohio State. This paper is a secondary analysis of one of Kiecolt-Glaser’s earlier studies showing that omega-3 supplements altered a ratio of fatty acid consumption in a way that helped preserve tiny segments of DNA in white blood cells.

Those short fragments of DNA are called telomeres, which function as protective caps at the end of chromosomes. Telomeres’ tendency to shorten in many types of cells is associated with age-related diseases, especially heart disease, and early mortality.

In the initial study, researchers were monitoring changes to telomere length in white blood cells known as lymphocytes. For this new study, the researchers looked at how sudden stress affected a group of biological markers that included telomerase, an enzyme that rebuilds telomeres, because levels of the enzyme would react more quickly to stress than the length of telomeres themselves.

Specifically, they compared how moderate and high doses of omega-3s and a placebo influenced those markers during and after an experimental stressor. Study participants took either 2.5 grams or 1.25 grams of omega-3s each day, or a placebo containing a mix of oils representing a typical American’s daily intake.

After four months on the supplements, the 138 research participants, age 40-85, took a 20-minute test combining a speech and a math subtraction task that is known to reliably produce an inflammatory stress response.

Only the highest dose of omega-3s helped suppress damage during the stressful event when compared to the placebo group, lowering cortisol and a pro-inflammatory protein by an average of 19% and 33%, respectively.

Results from blood samples showed that both doses of omega-3s prevented any changes in telomerase levels or a protein that reduces inflammation in the two hours after participants experienced the acute stress, meaning any needed stress-related cell repair – including telomere restoration – could be performed as usual. In the placebo group, those repair mechanisms lost ground: Telomerase dropped by an average of 24% and the anti-inflammatory protein decreased by an average of at least 20%.

“You could consider an increase in cortisol and inflammation potential factors that would erode telomere length,” Madison said. “The assumption based on past work is that telomerase can help rebuild telomere length, and you want to have enough telomerase present to compensate for any stress-related damage.

“The fact that our results were dose-dependent, and we’re seeing more impact with the higher omega-3 dose, would suggest that this supports a causal relationship.”

The researchers also suggested that by lowering stress-related inflammation, omega-3s may help disrupt the connection between repeated stress and depressive symptoms. Previous research has suggested that people with a higher inflammatory reaction to a stressor in the lab may develop more depressive symptoms over time.

“Not everyone who is depressed has heightened inflammation – about a third do. This helps explain why omega-3 supplementation doesn’t always result in reduced depressive symptoms,” Kiecolt-Glaser said. “If you don’t have heightened inflammation, then omega-3s may not be particularly helpful. But for people with depression who do, our results suggest omega-3s would be more useful.”

The 2.5-gram dose of omega-3s is much higher than what most Americans consume on a daily basis, but study participants showed no signs of having problems with the supplements, Madison said.

Celebrating World School Milk Day by making milk safe and accessible to Filipino school children

Tetra Pak believes that attaining a sustainable future is anchored on initiatives protecting people and the planet. That is why alongside its efforts in ensuring safe nutrition for children, Tetra Pak is also helping promote sustainability in various communities by providing recycling training for teachers and students.

In light of World Milk School Day, a global event celebrating the benefits and success of school milk programs, world-leading food processing and packaging solutions company, Tetra Pak, draws attention to the role of multi-stakeholder collaborations to sustainably address childhood nutrition by making fresh milk safe and accessible for everyone.

In the Philippines, Republic Act 11037 also known as an Act Institutionalizing a National Feeding Program for Undernourished Children in Public Day Care was a breakthrough development that mothered the School-Based Feeding Program (SBFP) of the Department of Education.

For the 2020-2021 School Year, it surpassed the target of providing nutritious food products and pasteurized or sterilized milk to 1.7 million beneficiaries from primary public school students in daycare, kindergarten, and elementary schools across the country. Despite the many challenges posed by the COVID-19 pandemic, DepEd SBFP recorded an achievement rate of 183.46% for the milk component and  198.15% for the Nutritious Food Products (NFP) component for the 2020-2021 School Year.  

As the SBFP aims to reach more schoolchildren and communities, RFM Corporation, a home-grown food and beverage leader, highlights the advantages of using UHT milk or milk that went through Ultra High-Temperature pasteurization, thus is safer and has a longer shelf life. This is an important feature considering infrastructure challenges and the lack of refrigeration to distribute the milk in far-flung areas.

Tetra Pak has been helping RFM Corporation deliver Selecta Kids Fortified Milk in Tetra Wedge® Aseptic 200ml Slim, a carton package that protects both the nutritional value and the taste of the milk for up to 12 months. Introduced in 2021, so that children in various parts of the country could have access to safe nutrition, Tetra Wedge® Aseptic Slim uses aseptic technology to ensure that the packaging materials and product inside it are free from harmful bacteria. Like all Tetra Pak carton packages, it’s made of renewable materials and recyclable paperboard, making it one of the best ways to feed the future sustainably.

According to Ms. Marie Concepcion-Young, Senior Vice President and General Manager, Consumer Group of RFM Corporation, “Milk help school kids reach their physical and cognitive potential. Aside from making it accessible, it is imperative that the milk stays fresh and safe even as we transport it to hard-to-reach areas or those with limited storage facilities.” 

During the first phase of SBFP Milk Component, Selecta Kids Fortified Milk in Tetra Wedge® Aseptic 200ml Slim was delivered to schools in Bicol, Davao, and Soccsksargen regions benefitting 359,557 school children. Tetra Pak together with Tetra Laval Food for Development is likewise providing practical support where they share best practices in school milk programs organization and implementation, as well as providing environmental education.

“For decades, we have been working with our customers and relevant stakeholders to support school feeding programs around the world because we believe these are effective in addressing poor health and nutrition in disadvantaged communities,” said Michael Wu, Managing Director, Tetra Pak Malaysia, Singapore, Philippines, and Indonesia.

He adds that “We are committed to making food safe and available, everywhere.  That is why we make sure that school children get all the goodness of milk to have the energy to stay in school and get that brain boost they need for learning.”

Tetra Pak believes that attaining a sustainable future is anchored on initiatives protecting people and the planet. That is why alongside its efforts in ensuring safe nutrition for children, Tetra Pak is also helping promote sustainability in various communities by providing recycling training for teachers and students.

“Whether it is addressing food availability or environmental concerns, we believe that real, lasting impact in society can be achieved if stakeholders work together,” Wu concludes.

From changing weather patterns to disease outbreaks, we are already feeling the effects of global warming. We need to act now and work together in protecting the planet.

Understanding that collective effort is the way to go, retail giant SM Supermalls is committed to helping all Filipinos make more environmentally friendly choices in every aspect of their life.

“Many people care about the planet but find it hard to create a green lifestyle because of limited time or budget. That’s why we have community programs that make it more convenient and affordable to be an eco-warrior,” says Jonjon San Agustin, SVP for Marketing, SM Supermalls.

Here are five easy ways on how you and your family can live greener.

Segregate your trash and Trash to Cash

Segregating your biodegradable and recyclable waste reduces the amount of trash that goes into landfills. Have separate containers for different kinds of trash: biodegradable for food and garden waste; recyclable for plastic, paper, and metal waste; residual waste for trash that can’t be recycled including used tissue or paper plates; electronic waste for old batteries or broken gadget which shouldn’t be mixed with other waste because they contain metals that can contaminate the soil.

You can bring your recyclable waste to SM Supermalls’ Trash to Cash Recycling Market, held 10 am to 2 pm on every first Friday and Saturday of the Month. Visit this link to find the kiosk locations near you.

Limit the use of plastic through Plastic Waste Collection

Did you know that it takes plastic over 1,000 years to decompose?

About 10% of plastic materials will end up in the ocean and can kill marine life. In the Philippines, plastic waste often congests sewage systems causing floods. You can avoid using single use plastic by bringing your own reusable containers or eco bags when going to the groceries.

You can also buy items in eco-friendly packaging.

Plastic cutlery and straws are optional during order delivery or takeout. For dine-in, you can have your own eco-kit which has a drinking bottle, a set of utensils, and a foldable eco bag. Go green anytime and anywhere!

You can also recycle your plastic waste through SM Supermalls’ Plastic Waste Collection programs. Make it a fun weekend and volunteer for SM by the Bay and SM Mall of Asia’s regular ocean clean-up drives.

Plant a garden

Plants help stop climate change by removing carbon dioxide from the air. If you don’t have a large yard for a garden, you can still get houseplants! There are many creative and beautiful ways to add more plants to a small home like using a backless bookshelf or installing vertical gardens.

Get plants, tools, and expert tips on how to take care of your home garden at SM Mall. You can also find beautiful containers like terrariums and plant hangers that are made by Filipino SMEs.

Buy eco-friendly products

Choose more environmentally friendly products to gradually create a sustainable lifestyle.

Environmentally friendly products can be reusable or biodegradable. They are usually made from sustainable materials with eco-friendly packaging. They also produced less toxic waste during manufacturing and after disposal.

You can find thousands of eco-friendly products within SM malls through the recently launched Green Finds pop-up stores. The selection of products can help go green in every aspect of your life.

Reuse as much as you can

Before you throw anything away, consider if the item can be either upcycled into something useful, or donated to someone who needs it. SM holds regular toy and book drives, where you can even get discount vouchers to use in the store.

Join the Green Movement

The SM Green Movement is a collective effort of SM, its customers, communities, and partners to promote green living, green culture and a green planet. For more information, visit this website.
