Trees help to clean the air and provide a relaxing setting to reduce stress.

Do you know how vital trees really are? Trees conserve soil and water and clean the air. Research has shown that there are both mental and physical health benefits from forests. Trees provide us with oxygen through photosynthesis. Not to mention, think of the beauty they add to an area. Florida has celebrated Arbor Day for many years, since 1886 to be exact. It is the third Friday in January, whereas the National Arbor Day is the last Friday in April.
We can improve our health just by spending time outside in nature. Forests and trees can boost our immune system, reduce stress, increase our ability to sleep as well as boost energy levels while improving mood and helping us to focus. Studies in health care show a link between nature and health. Plants put off airborne chemicals called phytoncides to repel insects. The antifungal and antibacterial qualities that are put off in this process help us as we breathe them in by increasing our white blood cell count.
It is important that we remove ourselves occasionally from our office or home to explore green spaces to take a mental break. That might mean a walk in the forest, gardening, exercising, or resting and meditating to unplug from our fast-paced busy life. Many doctors encourage and incorporate this type of therapy for wellness for their patients and for children diagnosed with attention deficit disorder.
There are many ways to celebrate trees. They are a great gift for birthdays, holidays, or anniversaries. You might also consider planting a tree in honor of a family member who has passed on or to remember a beloved pet. This year, give a gift that gives back as well as be encouraged to celebrate Florida’s Arbor Day on January 21st, 2022.
Many holidays celebrate something we remember, but Arbor Day is a way to celebrate hope for the future by planting a tree to support a healthy community. I encourage you to check with your local government offices, Forrester, or Extension office to see if there are any special celebrations planned that you could join or plan your own activity to honor trees as a resource and how they impact your environment.

Take care of your bones today for better quality of life tomorrow!
According to the National Institutes of Health, about one in every two Americans over the age of 50 may already have or be at risk of developing osteoporosis. (1) Osteoporosis is a disease where, over time, bone quality and strength decline, making bones more likely to fracture and break. Fractures can develop not only as a result of a slip or fall but also from everyday sneezing or coughing. If your doctor diagnoses you with osteoporosis, the best course of action for slowing its progression may be prescription medication. However, nutrition and exercise can help provide a good foundation to prevent or delay disease development. (1)
Know Your Risks
While all risks are not completely understood, there is a genetic factor linked to osteoporosis – mainly, if poor bone mineral density runs in the family. In addition to genetic factors, poor nutrition, smoking, excessive alcohol, and a lack of exercise can all increase your risk of developing osteoporosis. It is important to talk to your doctor to discuss your level of risk and prevention measures. (1)
Build More Bone
Although they may not seem like it, bones are a living tissue and go through times of building and breakdown during the life cycle. Bones grow the most during childhood, but they also change and become stronger as an adult by doing exercises like weightlifting or running. (1) Similar to a savings account or retirement fund, the more you build when you are young, the more you can afford to spend as you age. Current recommendations to support strong bones include muscle strengthening exercises at least two times per week. These exercises require your muscles to do more work than doing just day-to-day activities. Additionally, strength training exercises should be done to the point where it would be difficult to perform one or two more repetitions. Examples include lifting weights, working with resistance bands, and doing body weight exercises such as push-ups, pull-ups, and planks. Additionally, climbing stairs, and carrying heavy loads (such as groceries and heavy gardening) also count when done frequently.(2)
Support Your Bones
In addition to exercise, nutrition plays a large role in promoting healthy bones. The two most important nutrients for bone health are calcium and vitamin D. Calcium is what gives bones their strength but is also involved in many other processes in the body. If you do not regularly consume enough calcium, your body takes it from your bones. (3) If this happens for long enough, your bones will become weakened and begin to develop osteoporosis. Vitamin D is important for the absorption of calcium. Not having enough vitamin D can impact your bones, even if you get enough calcium from your diet. (4)

Bone Strengthening Foods
There are a variety of food sources that provide calcium and vitamin D. Calcium can be found in dairy products, green vegetables, and calcium-fortified foods. Examples of calcium-containing dairy products include cheese, yogurt, and reduced-fat milk. Other calcium-fortified foods include breads, orange juice, cereals, and tofu. When it comes to vitamin D in your diet, be sure to include fatty fish such as tuna and salmon. There are smaller amounts of vitamin D found in cheese, mushrooms, and beef liver. Similar to calcium, there are many vitamin D-fortified foods available. Some examples are cereals, orange juice, milk, and milk products. Check out the two tables below for calcium and vitamin D food sources. (5)

Stay Safe and Healthy as You Age
Osteoporosis can be a serious and life changing diagnosis. However, adopting healthy habits like limiting smoking and excessive alcohol consumption can decrease your risk. Consuming enough calcium and vitamin D each day and getting regular muscle building exercise at least twice a week can also help protect your bones. Women over the age of 65, or anyone diagnosed as “at risk,” should be regularly screened for osteoporosis by a doctor during their yearly physical health exam. (6,7,8)
Making healthy lifestyle choices from a young age can help prevent or delay osteoporosis, but once you’re diagnosed, the best course of action for slowing its progression may be prescription medication. Consult your doctor before beginning a new exercise program or for interactions with medications.

Until July 2, 2021, I felt confident I had done everything possible to stay safe and avoid contracting Covid-19. Throughout 2020 and well into 2021, I worked from home, socialized very little, quarantined when necessary, wore my mask, and constantly washed my hands. In fact, I may have dry skin on my hands for the rest of my life, but I still wash my hands frequently. The Covid-19 virus has become a controversial issue over the past two years, but my story is from real experience.
Keeping your fever under control is a necessity when battling Covid-19. Photo credit: Melanie Taylor
As I prepared to have a safe, but fun, Fourth of July weekend with a few vaccinated friends, I was winding down my Friday at work and started to feel achy. I headed home, excited for a 3-day weekend, but I still felt like I was dragging. My husband and I had plans to meet up with friends at a restaurant with outdoor seating, but before I left the house, I decided to take my temperature, just to be cautious. To our surprise, I had a fever of 99.9. We canceled our dinner plans and I took some acetaminophen, went to bed early, and we prayed it was not Covid-19. It was kind of an unspoken prayer because neither of us wanted to admit we were a little nervous about my symptoms. As the weekend carried on, I felt sicker as the hours and days went by and barely left the sofa or bed. On Sunday morning, I woke up with a bad dry, hard cough so my husband called my doctor. To be totally transparent, I am immunocompromised, so we both knew there was a chance I could have a breakthrough case even though I was vaccinated. Based on my symptoms, my doctor recommended I go to the emergency room and be evaluated since it was a 3-day weekend. I followed his directions, had a chest x-ray, which, thankfully, was clear, but I tested positive for Covid-19.
Let me honestly say, this was the sickest I had ever felt in my memories. For about twelve straight days, I laid on the sofa, took my temperature and oxygen levels, had no sense of taste or smell, ate food with no taste to keep up my strength, hydrated, and slept. The body aches, fever, dry cough, and fatigue were debilitating. I had every Covid-19 symptom listed by the CDC except for a headache. I thought to myself many times how bad and scary this could have been if I had not been vaccinated. My doctor clearly expressed his opinion that if I had been unvaccinated, I would have been hospitalized, no questions asked. Unlike many people, it was not recommended for me to take a regimen of pills or vitamins, so I fought it with acetaminophen, lots of hydration, healthy foods, and tons of rest. When I finally woke up on July 14th and could smell the coffee brewing, I knew the end was finally in sight. It still took two more weeks to feel and return to normal, and I knew firsthand this virus is no joke.
Like many of you, I know people that have tested positive and showed no symptoms, some that felt very sick but were able to stay home and recover, and some that never made it home from the hospital. I work in the field of science as a UF/IFAS Extension Agent and feel very strongly that we can all make simple efforts to reduce exposure to ourselves and others. The most important step is to pay attention to the symptoms and stay home if we suspect illness or exposure. Even though I was looking forward to the holiday festivities, I made a conscious decision to stay home on July 2nd just in case I really was positive with Covid-19. I wanted to keep my friends and family safe just in case there was a remote chance I was contagious. I feel very grateful I did not expose them to this virus.
Checking your oxygen levels while sick with Covid-19 is a must. Photo credit: Melanie Taylor
The positive cases in Florida are lower right now, and that is fantastic. I am very excited about it too, but I also know we still shouldn’t put our guard down. Please stay aware. Be aware if you or a family member(s) have been exposed or do not feel well, and check for symptoms. I highly recommend every American household have a reliable thermometer, a pulse oximeter (safe oxygen levels should not go lower than 92), fluids for hydration, and foods of different textures because eating food without being able to taste and smell is very difficult. Different food temperatures, spice levels, and textures made eating to keep up my strength easier for me to handle.
The past two years have been stressful, emotional, and very exhausting. We still cannot forget to stay aware and diligent in our everyday lives to keep our families, friends, and communities healthy. Please revisit these CDC websites as needed and always consult your doctor when you have questions and concerns. Stay aware and healthy out there!

What do you think of when you hear the word bacteria? If you are like most people, you probably think of those teeny, tiny germs that are invisible to the naked eye, but have the potential to cause serious illness. And while you would not be wrong to think that way, you would be leaving out a huge percentage of bacteria that are considered “good” bacteria.
The common name for “good” bacteria is probiotics (from the roots pro and biota, meaning “for life”). They are a group of beneficial microorganisms that have been shown to improve a variety of digestive and other conditions, such as irritable bowel syndrome and urinary tract infections.
Foods like Greek yogurt are a good source of probiotics, which have been shown to have a positive effect on digestive health. (Photo source: Samantha Kennedy)
Probiotics are found in a variety of foods, primarily fermented foods such as Greek yogurt and cottage cheese, fermented drinks such as buttermilk and kombucha, and pickled vegetables such as pickles and sauerkraut. The bacteria required for the fermentation process – the process that gives these foods their tangy flavor – have been shown to provide natural health benefits.
The primary benefit of probiotics is their positive effect on a variety of gastrointestinal ailments such as diarrhea, ulcerative colitis, Crohn’s disease, and stomach ulcers. According to Harvard Medical School, probiotics can also help reduce the presence of harmful bacteria, such as H. pylori and C. difficile, both of which can cause digestive problems.
In Northern Europe and many Asian countries, people get probiotics mainly from food sources, where fermented foods are consumed more regularly. Here in the United States, many people get probiotics from over-the-counter (OTC) supplements. These products are not regulated by the Food and Drug Administration, however, so when choosing OTC supplements, be wary of the claims they make.
The information about probiotics is not all positive, however. Some people report an increase in diarrhea after taking probiotics for the first time, which usually goes away with time. Also, people with a compromised immune system may experience illness caused by probiotics if too many are taken.
That being said, OTC probiotics have also been shown to have positive effects on health, when taken as directed. However, they are not a cure-all, and more research needs to be done to learn more about their complete effects on gastrointestinal health and immune support. Just like with other supplements, it is important to consult with a physician or pharmacist before beginning a probiotic regimen.
So, what is the final word on probiotics? Well, it depends. While they are not a magic bullet that can cure everything that ails you, they can be a positive addition to a healthy diet. Many foods that contain probiotics also contain other important nutrients such as protein, vitamins, and minerals, which are an important part of a nutritious diet.
One more thing: do not confuse prebiotics with probiotics. Prebiotics are non-digestible, short-chain carbohydrates that serve as fuel for probiotics. On their own, they do not offer any health benefits, but they can serve to promote the growth of probiotic species. Foods with high amounts of prebiotics include fruits and vegetables and whole grains, so a diet rich in these foods can help promote the growth of beneficial bacteria.
To learn more about probiotics, please contact your local Extension agent.

If you’ve tried to find nutrition information in the midst of the Covid-19 pandemic, you probably got more than you bargained for. Recently, I searched “nutrition and COVID-19” and in less than one second, I got 590,000,000 hits. That’s a lot of information! With so much health and nutrition information available, especially connected with the ongoing pandemic, it can be TOUGH to separate fact from fiction. What makes it even tougher is that everyone seems to be passionately and totally convinced that their information is the right answer. How do you tell the hype from the truth?
Confusing Nutrition Choices

The best way to protect yourself against questionable information and products is to become an informed consumer. That can be challenging as so many of us are becoming more used to getting our information from social media, websites, advertisements, friends and family. While information from those sources can be accurate, very often it is misleading. Use the following tips to evaluate nutrition information:
Know Your Experts:
Have you ever seen nutrition advice from a “nutritionist” or “diet counselor”? Beware, because those terms aren’t regulated, and almost anyone can use them to look like an expert. Registered dietitians (RD) or licensed dietitians (LD) hold specialized degrees and are good sources of solid nutritional information.
Media Sources:
The internet, books, newspapers, and magazines can be good sources of information, if you know where to look. If you’re surfing the net, select websites from credible web addresses like ones ending in .edu (universities or medical schools), .gov (government agencies), or sometimes .org (not-for-profit research and education). If you’re reading an article, always look for the author’s qualifications and membership in a professional nutrition organization. With all media, check the sources they used (If they don’t cite credible sources you can check, that’s a big red flag) and scan to the bottom to make sure they’re not trying to sell a product. If you can buy a “miracle” product, a solution, or a quick fix from them, watch out! Their information may be convincing, but it is likely biased or incomplete. At best, it calls for caution and some deeper research.
The flood of health and nutrition misinformation isn’t going away, but learning to be an informed consumer is a powerful step in learning to protect yourself from being duped.
