October has arrived, and with it, the crisp air of autumn! While summer has bid its farewell, October brings its own charm — trees ablaze with vibrant colors, cozy evenings spent indoors, and the faint scent of winter on the horizon.
As comforting and nostalgic as October can be, it's also a time when many of us catch colds or come down with seasonal flu. With that in mind, today’s blog post will focus on how we can use the seasonal bounty of fall foods to boost our immune health and overall well-being.
Hope you enjoy :)
My intention: Present you a couple of fall based superfoods which pack impressive nutritional profiles to keep your health and immunity in check this autumn season.
FALL SUPER FOODS
Pumpkin
Pumpkin is a well-known fall food staple. This squash vegetable contains an impressive amount of vitamin A alongside a rich antioxidant profile, making it ideal for reducing the risk of various chronic diseases, such as cancer and eye conditions exacerbated by oxidative stress from a diet lacking in antioxidants. I have previously written on the topic of antioxidants and oxidative stress, and you can read more about it here.
Due to its high vitamin A content, as well as relatively high levels of vitamin E, iron, and folate, pumpkin has been shown to positively impact the immune system. In addition to immune health, vitamin A plays a crucial role in promoting good eye health. Pumpkin is also rich in lutein and zeaxanthin, two compounds linked to lower risks of age-related macular degeneration (AMD) and cataracts.
Sweet Potatoes
Sweet potatoes now come in a variety of forms, sizes, and colors. They are not limited to just orange but can also be white or purple.
All sweet potato varieties are rich in a multitude of nutrients, namely vitamin A, vitamin C, manganese, copper, antioxidants, vitamin B6, and, importantly, fiber.
Due to their high fiber content, sweet potatoes positively affect gut health by feeding beneficial gut bacteria, which produce short-chain fatty acids. These acids reduce the risk of inflammatory diseases such as type 2 diabetes, obesity, and heart disease. Additionally, fiber is essential for maintaining regular bowel movements, contributing to a healthy lifestyle.
Some research has focused on purple sweet potatoes, which are high in a specific antioxidant known as anthocyanins. These have been shown to slow the growth of certain types of cancer cells in vitro.
Similar to pumpkins, orange sweet potatoes, which are rich in vitamin A, have been shown to positively influence immune health and promote good eye health.
Beetroot
Beets have been cultivated and used in cuisine for a long time. As a root vegetable, they boast an impressive nutrient profile, being high in vitamin B6, manganese, potassium, iron, vitamin C, and fiber.
Additionally, beets are naturally high in nitrate compounds, which effectively regulate blood pressure. Our bodies convert nitrates into nitric oxide, a chemical messenger that signals the cells in our arteries to relax and widen, thereby lowering blood pressure.
Due to their nitrate content, beets have also been suggested to enhance physical performance during high-intensity endurance exercise by reducing the oxygen demands of mitochondria, which produce ATP, the primary energy currency of our cells.
Cinnamon
I have previously written a comprehensive article on the health benefits of cinnamon, which you can find here. In brief, cinnamon is incredibly high in antioxidants, such as polyphenols, which protect our cells from oxidative damage and reduce inflammation.
Some studies have shown that regular consumption of cinnamon can have positive effects on heart health by lowering levels of triglycerides, total cholesterol, and blood sugar, thereby reducing the risk of heart disease.
Cinnamon has also been linked to improved blood sugar control by potentially enhancing insulin sensitivity, which helps combat diabetes caused by insulin resistance. It may also reduce the amount of glucose entering the bloodstream after meals by interfering with digestive enzymes that slow the breakdown of carbohydrates. Several studies suggest that cinnamon can lower fasting blood sugar levels.
Cranberries
Cranberries, a berry closely related to blueberries, bilberries, and lingonberries, are most commonly consumed as cranberry juice or dried cranberries due to their tart taste.
Cranberries are especially rich in A-type proanthocyanidins, compounds that play a protective role against urinary tract infections (UTIs).
This same compound has also been linked to protection against stomach cancer and ulcers, which are most commonly caused by the bacterium Helicobacter pylori. A-type proanthocyanidins can prevent these bacteria from attaching to the lining of the stomach.
Brussels Sprouts
Brussels sprouts belong to the Brassicaceae vegetable family, closely related to kale, cauliflower, and mustard greens.
These sprouts are very high in vitamin K, vitamin C, folate, plant fibers, and antioxidants.
Vitamin K is vital for proper blood clotting, while fiber benefits the gut microbiome by maintaining regular bowel movements and stabilizing blood sugar levels.
With their impressive antioxidant and vitamin C content, Brussels sprouts also help reduce inflammation-related diseases and assist the body in absorbing non-heme iron (plant-based iron sources).
