Research studies have proven that eating certain foods and getting the right amounts of vitamins and antioxidants can help you to stay healthy and ward off illness. Diet, exercise, age, stress, and other factors also have a big effect on our immune system’s response to disease and illness and all should be considered.
Besides just washing your hands, wearing a mask in public, and staying at home if you are ill, there is a lot that can be done to boost your immune system, which is your body’s first line of defense against disease and/or illness.
- First and foremost, DO NOT SMOKE. And, if you do, try your best to quit.
- Drink plenty of fluids – at least eight, 8-ounce glasses a day. And drink one of them as soon as you get up in the morning, as your body become dehydrated overnight.
- Eat a diet high in fruits and vegetables. Also includes protein and complex carbohydrates such as brown rice and quinoa. This is especially important for seniors, as we tend to eat less when we age.
- Exercise regularly.
- Keep a healthy weight.
- If you drink alcohol, drink in moderation.
- Get enough sleep.
- Try to minimize unnecessary stress.
- Stay up to date with all recommended vaccines.
- Maintain a healthy and positive attitude.
- Include probiotics in your diet if your doctor agrees they would benefit you, as robust gut bacteria protect us against infection. Colorful fruits and vegetables including berries, carrots, and spinach have antioxidants that protect you against oxidative stress, which translates to a stronger immune system.
- Kombucha (fermented, lightly sweetened black or green tea drink) and kvass (traditional Slavic and Baltic fermented beverage made from rye bread).
- Unpasteurized sauerkraut and kimchi.
- Yogurt, kefir (a thick, creamy, and drinkable yogurt), lassi (a drink made from a yogurt or buttermilk) and leban (a liquid or semisolid food made from curdled milk.
- Tofu, miso, natto (fermented soybeans), shoyu or tamari (types of Japanese soy sauce) and tempeh (an Indonesian dish made from fermented soybeans).
- Jerusalem artichokes, green bananas or plantains, Jicama root, and asparagus.
- Vitamin E is an antioxidant that increases the production of white blood cells to fight infections. Good sources are citrus fruits, papaya, dark green and yellow vegetables, red bell peppers, strawberries, tomatoes, and watermelons.
- Or take a probiotic supplement (again, if approved by your health care provider).
- Garlic: Allicin, a compound in garlic, is well-known for its ability to boost the immune system. The most benefit comes from eating one-half of a raw garlic clove daily. If you cannot stomach raw garlic, the next best thing is to roast it or you can mince it up and add it to salads, egg dishes, pasta, etc.
- Vitamin C-rich foods boost immunity. Studies have found that older adults who ate kiwi every day for a month had a significant decrease in the severity and duration of upper respiratory infection symptoms. If you eat the fresh fruit, rather than drink the juice of fresh fruit, it is better for you, contains less sugar, and has more fiber. Good sources of Vitamin C are oranges, broccoli, kiwi, or cantaloupe, etc.
- Vitamin A is known to keep our skin, vision, mouth, stomach, intestines, and reproductive systems healthy. Good sources are sweet potatoes, spinach, pumpkins, carrots, cantaloupes, and peppers.
- Zinc is a mineral that helps in wound healing and helps in the development of immune cells. Good sources are beans, grains, nuts, and seeds.

Muscle Health and Exercise for Seniors
As we age, our bodies change and can require a different type of exercise. And, though we may have been able to just jog or run on the treadmill in our younger years, we now need different types of exercise to build strength and muscle mass.
Are you a Stockpiler or a Sharer?
Years ago, when I was working as an ER nurse, I attended a mandatory in-service designed to enhance cooperation and productivity in the workforce. The trainer told a story entitled, Stone Soup. Most of my southern coworkers had all heard the story in one version or another, but being from New England, I never had. The story went something like this:
Are You a Hugger?
I grew up in a French family with lots of siblings, cousins, aunts, uncles, etc. and we hugged each other…A LOT! Since it was the preferred form of greeting, both in my family and the French Catholic community I grew up in, I always found it very normal. However, when I moved away from Northern Maine, I realized this is not always the case with everyone.
Looking at What We Don't Want to Face in Ourselves
To Volunteer or Not to Volunteer. That is the Question
Most of us look forward to that time when we could retire. We have worked hard all our lives and hopefully have saved for retirement. The first few months or even years of retirement are glorious. We do not have to get up before we want to in the morning, we can do what we like during the day, stay up later at night to watch a movie, or read a book, etc.
