Nutrition and Your Immune System

Nutrition and Your Immune System

Your health Is directly related to how well your body responds to fight bacteria and viruses that can lead to inflammation, infection, and illness. This line of defense against intruders is known as the immune system. You can support your immune system and keep it strong with regular handwashing, proper nutrition, physical health, and mental well-being.

A healthy lifestyle, including a diet rich in nutritious foods, is important to your well-being and ability to maintain your immune system. Nutrient deficiencies can impair immune function and decrease the body’s resistance to infections. Nutrients work together to build a healthy immune system to defend against sickness.

Nutrition Strategies to Boost Your Immune System

  • Don’t over-consume calories, saturated fats, or excess sugar and salt.
  • Eat a well-balanced diet that includes a variety of fruits, vegetables, grains, and legumes.
  • Read nutrition labels.
  • Consider taking a daily multivitamin.

All nutrients are important, but several are particularly important to supporting your immune health, including antioxidants, Vitamin C, Vitamin A, Vitamin E, Vitamin D, zinc, and omega-3 fatty acids.

Phytonutrients and Antioxidants

Phytochemicals are naturally occurring compounds in plants that protect plants from fungus, germs, and insects and are responsible for the color, taste, and smell of plant foods.

In the body, many phytochemicals, vitamins, and minerals act as antioxidants, which help to protect cells from damage. Phytochemicals have health properties that are:

  • Cardio-protective
  • Anti-diabetic
  • Anti-inflammatory
  • Anti-cancer

Vitamin C strengthens the immune system, repairs damaged cells, and helps defend against foreign invaders. Vitamin C is found in a wide variety of fruits and vegetables such as oranges, grapefruit, and bell peppers.

Vitamin A is known to promote healthy growth and distribution of cells, and support skin and eye health. Sources include orange vegetables (pumpkin, carrots, and sweet potatoes), leafy greens (spinach, kale, and broccoli), fish, dairy products, and eggs.

Vitamin E has antioxidant properties that protect cells from damage, support a healthy heart, and may help to prevent some types of cancer. Good sources of Vitamin E include many plant oils like sunflower oil and almond oil and healthy fats found in avocado and almonds.

Vitamin D is known to promote anti-inflammatory cells and help regulate cells involved in the immune response and healing. Vitamin D is also needed for the body to absorb calcium. Sources include sunlight (your body makes vitamin D from sunlight!), fortified foods (usually dairy and soy products), and fatty fish (salmon, tuna, and mackerel).

Zinc is a trace element shown to improve brain function and strengthen the immune system by promoting wound healing and decreasing inflammation. Zinc is found in lean meats, seafood, legumes, and nuts.

Omega-3 fatty acids are important in controlling inflammation. The body cannot make these fatty acids so they must be consumed in the diet. Plant sources include chia seeds, edamame, avocado, and oats, while animal sources include salmon and tuna.

What About Supplements?

If a well-balanced diet Is not regularly accessible, you may consider taking a multivitamin. Talk with your healthcare provider to decide if a daily multivitamin or other dietary supplements are right for you. Always be sure to read labels carefully for the serving size, ingredients, and “USP Verified” seal to ensure the supplement contains the actual ingredients listed and is made according to FDA guidelines. Choose a multivitamin that is all-inclusive to meet the daily RDA (Recommended Dietary Allowance). Adhere to the serving size to meet the RDA for daily multivitamins or individual vitamin supplements, unless instructed otherwise by a doctor. Dangers of supplement interactions or overdose include upset stomach, headache, and blocking other nutrients from being absorbed by the body. For more information about dietary supplements, visit the U.S. Food & Drug Administration or the National Institutes of Health – Office of Dietary Supplements.

What Does That Mean?

What Does That Mean?

Food marketing has made shopping for “healthy” foods complicated. Let’s dig in to see what some common “marketing” terms are and what they mean.

Let’s start with the term “natural.” There is no formal definition for what this term means regarding food marketing. However, the U.S. Food and Drug Administration considers “natural” to mean that nothing artificial has been added to the food. Often, consumers see the term “natural” on food products and interpret that to mean the product is healthy or organic. However, the term “natural” does not determine the health or nutritional benefit of the food product. A “natural” food may be healthy, but it may not be. The nutrition facts label with the ingredients list is where the consumer should read and decide whether the food product is nutritionally beneficial.

Now, let’s talk about the term “processed.” Processed means that the food has been altered in some way. It could simply be that the food has been washed, cut, and cooked. Take potatoes, for instance. A whole potato that has been washed and baked is considered minimally processed, and a whole potato that has been washed, cut into “fries”, and baked is also minimally processed. Both of these examples can be healthy options. Now, let’s take that further and think about store-bought potato chips. They are heavily processed. To turn whole potatoes into potato chips at a factory a lot more steps must happen than in the previous examples. The steps in the process of taking whole potatoes and turning them into chips take away nutritional benefits, while adding things such as unhealthy oils, salts, and other ingredients.

Another example of processed foods that can be healthy is canned green beans. Green beans are picked, washed, and canned typically all in the same day. The canning process does not usually decrease the nutritional benefits, especially for unsalted and low-sodium options.  The point is, some foods that are “processed” are still nutritionally beneficial while others are not.  Processed foods like cereal with added sugars, pre-packaged cakes, cookies, and chips are all foods that have unhealthy ingredients added in and those types of processed foods should be limited.

Another term food marketers will use is “unprocessed.” These are foods that are in their most natural state. For example, fresh strawberries are often picked and eaten right in the field, which is as unprocessed as it gets. It is important to incorporate unprocessed foods in the diet like fresh fruits, but it is also okay to consume minimally processed fruits and vegetables such as cooked or canned varieties.

Lastly, we will discuss the term “organic.” Organic does not define the nutritional benefits of a product. Organic means grown without the use of most conventional pesticides. For companies to be permitted to use the term organic on their products their farms are inspected and approved by a governmental inspector who will then determine if the criteria have been met for them to add “organic” on the labels. A product that has the term “100% organic” means the entire product is organic. A product with just the term “organic” on the label means that at least 95% of the ingredients are grown with organic ingredients. The term “made with organic ingredients” means that 70% of the ingredients in the product are certified organic.

Food marketers try to use terms such as these above to get the consumer to pay more for a product or to purchase their product over a competitor’s. It is ultimately up to you, the consumer, to decide what is healthy and nutritionally beneficial for you and what your budget will allow. Don’t be fooled by marketing terms to think that the product you are buying has more nutritional benefits than others just because the product is marketed in such way. To make an informed choice on what is nutritionally healthy, you must read the nutrition facts label and the ingredients list.  From there, you can determine what is the best choice for you and your overall health no matter what marketing terms are on the product.

Safe & Effective DIY Pest Control

Safe & Effective DIY Pest Control

Do you reach for the can of bug spray at the first sight of a pest? Many people do, but did you know there are other less toxic methods for controlling ants, cockroaches, and other vermin in and around your home? Integrated Pest Management, or IPM, is an approach that uses a variety of strategies to discourage the development of pest populations and to reduce pesticide use. These strategies are not difficult or expensive and promote a cleaner, healthier environment.

PREVENTION

  • Check grocery bags, book bags, and lunch containers for cockroaches before bringing them in your home.
  • Cockroaches LOVE cardboard boxes and paper bags. Dispose of unnecessary boxes and bags immediately to eliminate breeding areas. Transfer items for storage to plastic totes with snap-on lids.
  •  Repair or replace torn window and door screens to keep ants, cockroaches, and mosquitoes from entering your home.
  • Apply weather stripping around exterior door frames. Cockroaches can enter through an opening the thickness of a dime so small gaps around your doors are all they need to come in. If your door frame peeks light, your home is not tight!
  • Install door sweeps on exterior doors to make it harder for ants and cockroaches to enter. Make sure the sweep brushes the floor to keep insects out.
  • Ants and cockroaches often enter a home looking for water, especially during dry spells. Seal gaps and openings around pipes with expanding spray foam to eliminate these entry points.
  • Regularly empty standing water in flowerpots, tires, outside toys, and other containers to cut down on mosquito larvae.

Sanitation

  • Wash dishes immediately after use.
  • Wipe counter tops regularly, especially after food preparation.
  • Keep small and large appliances clean and free of crumbs and other debris. Don’t forget to clean around them, too.
  • Store food in sealed packages or containers or in the refrigerator.
  • Close garbage container lids, empty garbage regularly, and keep the container and area clean.

Chemical control
Baits are most highly recommended because of their effectiveness and targeted application, while decreasing unnecessary pesticide exposure. They come in granular forms, in plastic stations, or in large syringes for gel application and in formulas targeted specifically for ants or cockroaches.

  • Apply granular formulations outside in plants and mulched areas.
  • Use bait stations around corners where you suspect cockroaches or ants are hiding or entering your home.
  • Apply gel baits in cracks and crevices around windows, doors, behind the range, and any other suspected harborage areas.
  • Pest control operators have other baits in different forms that also provide long-lasting control.

Simple, everyday habits can go a long way toward eliminating an inviting environment for pests.

Summer Beach Fun Includes Beach Safety

Summer Beach Fun Includes Beach Safety

A great beach outing includes more than just grabbing the sunscreen and a towel on the way out the door. A bit of quick planning can really aid with a successful beach outing that doesn’t require too much effort.

Staying hydrated is important. Freezing bottles of water, sports drinks or fruit drink pouches is one trick to packing a smaller cooler or an insulated grocery bag. It is dual purpose. It can aid with keeping snacks (apple slices or watermelon in resealable bags) cool and when melted, a cool drink to enjoy.

Snacks are a also good idea. Fruit, animal crackers, or pretzels are easily packed and not too difficult to manage. Another tip is to bring a trash bag to keep the beaches clean and to limit your trips to the public waste receptacle.

Sunscreen is a necessity even on a cloudy day. A sun protection factor (SPF) of 15 or more by is recommended by the U.S. Food and Drug Administration (FDA). Applying sunscreen before leaving home allows time for adequate absorption into the skin. Remember to reapply at least every 2 hours. Using an umbrella or a tent is a great way to escape the sun’s direct rays. Wearing a hat or other protective clothing can help protect from those harmful UV rays.

Have kiddos? Bringing a few toys to aid with building sandcastles keeps the creative mind going. A few simple safety rules for playing in the sand are: do not bury one another in the sand, avoid throwing sand at anyone as it could harm one’s eyes, and avoid digging deep holes. Safety is paramount and an article published in the New England Journal of Medicine by a Harvard Medical School researcher noted burying a person in the sand is dangerous as the weight of the sand may lead to suffocation. As recently as February 2024, at Lauderdale by the Sea, two children were involved in a beach hole collapse, as reported in the Miami Herald. While digging in the sand is fun, be mindful and create structures that are safe for the kids.

Finally, know your beach flags and where to locate the current beach conditions. The National Weather Service as well as the MOTE Marine Laboratory are great sites providing beach conditions, including water current risk level, UV index, and thunderstorm potential. Local beaches often have social media pages that provide specific data for that area, including the current conditions and flags. Remember, not all beaches post flags and not all beaches have lifeguards on duty.

A day at the beach is an excellent opportunity for a fun-filled day. While this may not be an inclusive list, it does cover many of the basics of a good beach day. Spending a few minutes to determine the beach outlook, gathering the day’s supplies, and following some safety rules can greatly enhance your beach day.

Mindful Stress Relief

Mindful Stress Relief

In today’s fast-paced and demanding world, stress has become an all-too-familiar companion for many individuals. The pressure to perform, meet deadlines, and juggle personal responsibilities can leave us feeling overwhelmed and anxious. Mindfulness, the practice of being fully present and aware of the current moment, offers a powerful antidote to stress. By cultivating mindfulness, we can gain greater control over our thoughts and emotions, leading to reduced stress levels and improved overall well-being. In this article, we will explore four mindfulness tips that can help us effectively manage stress. 

Embrace the present moment. One of the core principles of mindfulness is to embrace the present moment without judgment. Stress often arises from dwelling on the past or worrying about the future. By redirecting our focus to the here and now, we can break free from the cycle of stress. A simple yet effective way to achieve this is through mindful breathing. 

Start by finding a quiet space and sit or lie down comfortably. Close your eyes and bring your attention to your breath. Feel the sensation of the breath entering and leaving your body. If your mind starts to wander, gently redirect your focus back to your breath. Engaging in this practice for just a few minutes each day can help rewire your brain to stay anchored in the present moment, reducing stress and increasing mental clarity. 

Cultivate gratitude. Gratitude is a potent mindfulness tool for combating stress. When we practice gratitude, we shift our attention away from what is lacking in our lives to what we already have. This shift in perspective fosters feelings of contentment and happiness, effectively reducing stress and anxiety. 

Each day, take a few moments to reflect on the things you are grateful for. They can be as simple as a warm cup of tea, a kind gesture from a friend, or a beautiful sunset. Keeping a gratitude journal can also be beneficial, as it allows you to document and revisit these positive aspects of your life regularly. As you consistently practice gratitude, you will notice a gradual decline in stress and a greater sense of overall well-being.

Practice mindful movement. Physical activity is an excellent way to manage stress, and when combined with mindfulness, its benefits are even more profound. Engaging in mindful movement practices, such as yoga or tai chi, not only enhances flexibility and strength but also helps calm the mind. 

During these activities, concentrate on the sensations in your body, the rhythm of your breath, and the flow of movement. By keeping your attention on the present moment while you exercise, you create a mental space that allows stress and worries to dissipate. Moreover, mindful movement encourages a mind-body connection, promoting relaxation and a sense of inner peace. 

Take a tech time-out. In today’s digital age, it is easy to become glued to our devices, which can lead to information overload and heightened stress levels. Mindfulness involves being fully present in the real world, not just in the virtual one. To reduce stress, it is essential to set boundaries with technology and limit screen time. 

Allocate specific periods during the day to disconnect from your phone, computer, and other electronic devices. Use this time to engage in mindful activities, such as taking a walk in nature, reading a book, or spending quality time with loved ones. By reducing our exposure to the constant stream of information, we can create mental space and experience greater calm and balance. 

Incorporating mindfulness into our daily lives is a powerful strategy for reducing stress and nurturing overall well-being. Remember, mindfulness is a skill that improves with practice, so be patient with yourself as you embark on this journey toward a stress-free existence.

Reducing Stigma Surrounding Mental Illness

Reducing Stigma Surrounding Mental Illness

Since the beginning of the COVID-19 pandemic, conversations about mental health have gained momentum, and the importance of addressing mental illnesses is finally being recognized. However, despite this progress, the stigma surrounding mental illness remains a formidable barrier to seeking help and support. In this article, we will explore the significance of reducing the stigma associated with mental health issues and how our collective efforts can pave the way for a more compassionate and understanding society. 

Stigma, in the context of mental illness, refers to the negative attitudes, stereotypes, and discrimination that individuals with mental health conditions often face. This pervasive stigma affects people from all walks of life, preventing them from seeking treatment, sharing their experiences, and living fulfilling lives. The fear of judgment and misconceptions about mental illness have perpetuated this stigma for far too long. 

The consequences of mental health stigma are far-reaching and detrimental. People who experience mental health challenges may avoid seeking help due to the fear of being labeled as “weak” or “crazy.” This hesitation to seek professional support can worsen their conditions, leading to prolonged suffering and potential crises.

Moreover, stigma affects relationships, communities, and workplaces. Individuals struggling with mental health issues may face isolation, discrimination, and reduced opportunities for personal and professional growth. This not only affects their well-being but also hinders the productivity and inclusivity of our society. 

One of the most effective ways to combat mental health stigma is through education and awareness. Misinformation breeds fear, and fear perpetuates stigma. By providing accurate information about mental health conditions, their prevalence, and available treatments, we can dispel myths and promote empathy and understanding. 

Schools and workplaces can play a pivotal role in fostering awareness by integrating mental health education into their curricula and employee wellness programs. Initiatives like mental health seminars, campaigns, and awareness events can encourage open discussions and create safe spaces for sharing experiences. 

Personal narratives have the power to challenge misconceptions and humanize mental health issues. When public figures, celebrities, or even everyday individuals share their stories of coping with mental illnesses, it sends a powerful message of hope and resilience. These stories prove that mental health challenges are not insurmountable and that seeking help is a sign of strength. 

Media outlets can also contribute significantly by responsibly portraying mental health in films, TV shows, books, and online. By avoiding sensationalism and accurately depicting mental health experiences, the media can break down stereotypes and contribute to a more compassionate portrayal of those affected. 

Communities must come together to create a supportive environment for individuals living with mental health conditions. This involves fostering empathy, compassion, and active listening. Support groups and helplines can provide vital assistance and reduce the isolation felt by those struggling with their mental health. 

Furthermore, workplaces should adopt mental health-friendly policies that prioritize employee well-being. Encouraging open conversations about mental health at work and offering accessible resources like counseling services can make a significant difference. 

The government and healthcare institutions also bear the responsibility of reducing stigma and improving mental health services. Adequate funding for mental health programs, increasing the availability of mental health professionals, and integrating mental health into primary care are crucial steps toward addressing the issue.
