Colder, drier air, less sunlight, more time spent indoors, increased holiday travel, and more mixing and mingling all contribute to rising rates of illness in the winter months. While no single food or supplement can prevent or treat illness, a balanced diet with the right combination of key nutrients can support a healthy immune system—making it easier for your body to fight off illness and infection.
A food-first approach is recommended when it comes to obtaining these nutrients. This means focusing on whole foods as your primary source rather than relying heavily on supplements. Below are several key nutrients for maintaining a healthy immune system this winter and the foods in which they can be found.
Vitamin C
Vitamin C is a well-established immune-supporting nutrient. It serves as an antioxidant, helping fight off cellular damage that can make cells more susceptible to illness and infection. It also supports the function of phagocytes, the cells that “eat” pathogens.
Most fruits and vegetables contain vitamin C, but seasonal quality can vary this time of year. It can be helpful to choose those that are in season, such as citrus fruits (oranges, clementines, grapefruits) and their juices, pomegranates, kiwis, bell peppers, and leafy greens like kale, Brussels sprouts, broccoli, and cabbage. Frozen fruits are also a great option, as they are typically picked at peak ripeness and remain just as nutritious as fresh varieties.
Vitamin D
Vitamin D helps activate white blood cells that detect and destroy pathogens. Without adequate vitamin D, these cells are not as effective. Sunlight exposure contributes significantly to vitamin D production, but during the winter months, sunlight and time spent outdoors decrease—leading to lower natural production. Vitamin D is also found naturally in very few foods, so unless you’re intentional about including these foods regularly, you may fall short.
Vitamin D is primarily found in fortified dairy products and dairy alternatives (almond, soy, coconut), fatty fish (salmon, mackerel, sardines, anchovies), egg yolks, and mushrooms exposed to sunlight. If you don’t consume several servings of these foods on a regular basis, your physician can order a blood test to determine whether your levels are adequate and if a supplement is indicated.
Zinc
Zinc plays an important role in the normal development and function of immune cells. It may also help inhibit the replication of certain viruses and bacteria, potentially shortening the length of infection. Zinc is best absorbed through animal sources such as beef, pork, turkey, seafood (oysters, crab, shrimp, sardines), eggs, and dairy products. It can also be found in plant sources, including seeds (pumpkin, hemp, chia), nuts (cashews, almonds, peanuts), beans, lentils, and whole grains.
No one supplement or food can prevent or treat illness, and diet is only one part of the equation. To further reduce your chances of getting sick this winter, remember to wash your hands regularly, sanitize frequently touched surfaces, cover your coughs, and stay well hydrated and well rested.
By focusing on nutrient-dense foods and simple daily habits, you’ll give your immune system the support it needs all season long.


Satiation
Thanksgiving is, in my opinion, the best holiday of the year. Theres no better way to express your love and care for someone than to make them a delicious meal and consume the delicious meal they made for you. Pair that with the added prospect of family members coming together from all over, and you’ve got great times waiting to happen. But sometimes love hurts, and on Thanksgiving that hurt takes the form of caloric surplus and post-meal shame. To prevent that, here are a few tips to help you enjoy the holiday to its fullest, free of any guilt:
Yoga and Stretch Classes
Feeling gratitude, or practicing it intentionally, can benefit our sense of happiness because we train our thoughts to entertain aspects of P.E.R.M.A. These thoughts serve our own greater good and connect us back to relationships, meaning, and life purpose. These thoughts are focused on things we value, regardless of the circumstances we are in.

Movement is considered one of the best forms of preventive medicine to protect our health. In a general sense, the more we move, the healthier we tend to be. Movement isn’t restricted to structured exercises. Your body doesn’t really differentiate between walking up a flight of stairs or stepping on a stair climber. The wonderful thing about physical activity is that our bodies inherently know how to recover and adapt.
Intuitive eating is the practice of eating in response to your body’s internal hunger and fullness cues, rather than external cues, such as environmental or social triggers that prompt eating behaviors, regardless of true hunger or fullness levels. In today’s society, it is especially difficult to eat intuitively as we are near constantly being bombarded with messaging that tells us what we should or shouldn’t eat and that labels foods as “good” or “bad.” Overtime, as the mind and body become used to ignoring hunger signals, the cues begin to fade and are more and more difficult to notice or may only be noticed when the body is in an extreme, ravenous state, which is likely to lead to overeating, which is then followed by feelings of guilt and desire to restrict based on external cues and continued ignoring of internal hunger cues. For many, the body must be reconditioned, starting with reconnecting with your biological hunger cues. Here’s how to start:
As the days grow shorter and temperatures drop, finding motivation to get to the gym can be tough. Between an increase in sickness, schedule changes, and chilly weather, it’s easy to lose your fitness rhythm. But sticking with your exercise routine during this time of year can actually help you feel better. Regular movement can boost your immunity, improve your mood, and increase your overall energy levels.
Tips for Staying Active
Weightlifting and resistance training are often associated with the “gym bro” or “jock” stereotype, as if the benefits only apply to people chasing new personal records or aesthetic goals. Because of that mindset, some might find it surprising to see an older adult in the weight room. If not to build muscle or break performance barriers, what’s the point? Wouldn’t it be dangerous for someone in their 50s, 60s, or beyond to lift weights? Surely nothing good could come from someone “older” picking up heavy objects regularly, right?
When you hear the phrase “speed training,” it’s easy to picture elite athletes—sprinters blasting off the line or pros flying down the field. But speed training isn’t reserved for them. Anyone can benefit from learning to move more efficiently, react faster, and generate more power. In fact, adding a little speed work to your weekly routine can help you feel stronger, more coordinated, and more confident in your movement—whether you’re running, lifting, or chasing your kids around the yard.
