Foods with functional benefits provide far more than just basic nutrition; they also offer health-promoting qualities. They have become increasingly popular due to the growing interest in healthy eating and the prevention of chronic diseases. Functional foods have been shown to possess disease-fighting properties, making them a valuable addition to a healthy diet.
In this article, we will explore some of the functional foods that can be particularly important for autoimmunity and bone health.
The following functional foods have been shown to reduce inflammation and support the immune system, potentially reducing the risk or severity of autoimmune diseases.
Berries: The sweetest functional foods
Bursting with flavor and packed full of nutrients, berries are an essential inclusion in any functional foods diet. But beyond their sweet and juicy taste, berries also possess a wide range of health benefits, especially for those concerned with reducing inflammation and promoting healthy bone development. Berries have been shown to be rich in antioxidants, nutrients, and phytochemical compounds that are beneficial for overall health and wellness.
Bursting with anti-inflammatory properties, berries are a powerhouse of health benefits. Berries contain a range of flavonoids, such as anthocyanins, quercetin, and catechins, which have been found to modulate
the inflammatory response in the body. These flavonoids work by interacting with various cellular signaling pathways and reducing the levels of pro-inflammatory cytokines in the body.
Antioxidants are another critical component of berries’ anti-inflammatory effects. Bursting with an abundance of antioxidants like vitamins C and E, carotenoids, and flavonoids, berries are a nutritional powerhouse easily added to your functional foods diet. These antioxidants can neutralize harmful free radicals produced by oxidative stress and inflammation, ultimately improving the overall health of the body.
Moreover, Vitamin C is abundant in berries and plays a pivotal role in the fabrication of collagen; an essential protein that provides strength and stability to bones.
Apart from antioxidants and flavonoids, berries also contain a wealth of essential nutrients that are integral to good overall health. For example, berries are an excellent source of vitamins, such as vitamins C, B vitamins, and vitamin K. They are also rich in minerals, including potassium, calcium, and magnesium. Consuming essential nutrients is imperative for strong, healthy bones. Not only do they help to increase bone density and strength but also ward off any potential loss in the future.
Phytochemicals, especially polyphenols, are another class of bioactive compounds present in berries that play a crucial role in bone development and inflammation. Polyphenols are potent antioxidants that protect cells from oxidative stress and inflammation. Studies have shown that polyphenols can inhibit the activity of enzymes that degrade the extracellular matrix of cartilage and bone, leading to improved bone health.
In particular, the polyphenol resveratrol, which is found in grapes and berries, has been found to have potent anti-inflammatory and bone-building properties.
Ultimately, berries possess a low glycemic index and load which keeps blood sugar levels in check without causing dramatic spikes. Elevated blood sugar levels cause the generation of inflammatory cytokines and oxidative stress, which encourage a range of long-term illnesses like osteoporosis. By stabilizing blood sugar levels, berries help to reduce inflammation and prevent the development of chronic diseases and are an essential tasty addition to any functional foods diet.
Fatty Fish as functional foods
Fatty fish, such as salmon, mackerel, and tuna, are well known for being rich in heart-healthy omega-3 fatty acids. But beyond that, researchers have found that seafood holds substantial amounts of vitamins, minerals, and other beneficial compounds that support overall health, including the significant anti-inflammatory benefits of fatty fish.
The primary component making this possible is omega-3 fatty acids, which can be found in high concentrations in fatty fish. Omega-3 fatty acids, particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), are potent anti-inflammatory agents that can reduce inflammation throughout the body by blocking the production of prostaglandins and cytokines, both of which are inflammatory mediators.
Moreover, fatty fish are also rich in antioxidants and nutrients that can help to reduce inflammation and support healthy bone development. For instance, fatty fish contains vitamins A, and E, which work as antioxidants to neutralize free radicals and decrease inflammation, while vitamin D found in fatty fish is critical in assisting the body in absorbing calcium, which is a vital component in building and maintaining strong bones. Similarly, minerals like selenium, magnesium, and zinc present in fatty fish aid in fighting inflammation and contribute to healthy bone development.
Fatty fish also contains collagen, a protein that supports healthy bones, joints, and skin. Collagen is a structural protein that provides a framework for the bones to create a strong, flexible structure. Fatty fish contains certain types of collagen that are particularly useful in promoting bone health, and slowing down or reducing the inflammation and pain that comes with aging.
Studies have revealed that adding fatty fish to the diet can potentially reduce the risk of several chronic conditions, including heart disease, autoimmune diseases, and even cancer. The anti-inflammatory benefits of fatty fish can help to reduce the low-grade chronic inflammation that is associated with these conditions while also promoting healthy bone development. [1]
However, it’s significant to keep in mind that excessive consumption of fish may lead to the intake of harmful compounds like mercury or polychlorinated biphenyls (PCBs), which can be detrimental to one’s health. To avoid ingesting high levels of pollutants in fish, it’s recommended to obtain fatty fish from reputable sources and avoid large predatory fish varieties. Oily fish are an essential addition to your anti-inflammatory bone-building functional foods diet regime.
Turmeric: One of nature’s essential functional foods
Turmeric is widely recognized for its distinct flavor and use as a spice in many cuisines. However, research has uncovered its potential health benefits beyond its role in cooking. Specifically, its anti-inflammatory and antioxidant properties make it a valuable functional food for fighting inflammation and supporting bone health.
The primary active ingredient in turmeric is curcumin, a natural compound that has been shown to have potent anti-inflammatory and antioxidant effects.

Furthermore, the magnesium in leafy greens helps to support calcium absorption and bone health.
Leafy greens and collagen
Leafy greens also contain compounds that help to promote collagen production. Collagen is a protein that is important for maintaining healthy joints, skin, and bones. As we age, our bodies produce less collagen, which can lead to sagging skin, joint pain, and weakened bones. However, by eating leafy greens, we can help to maintain healthy collagen levels and prevent these age-related problems. For example, kale and spinach are particularly rich in vitamin C, which is essential for collagen synthesis.
While plant-based silica is most commonly associated with rice, oats, and bamboo, it can also be found in leafy greens. In fact, many leafy green vegetables are a good source of this essential mineral. For example, kale, spinach, and collard greens all contain high levels of silica. Silica is essential for collagen production and helps to maintain healthy skin, hair, and nails.
Additionally, silica is important for bone health as it helps to improve bone density and increase bone mineralization. Therefore, incorporating leafy greens into your diet is a great way to increase your intake of plant-based silica.
In addition to these benefits, leafy greens are also known to contain anti-inflammatory compounds. For example, they are rich in flavonoids, which are plant compounds that have been shown to reduce inflammation and enhance immune function.
Furthermore, they contain omega-3 fatty acids, which have been shown to have anti-inflammatory effects on the body. Leafy greens are the cornerstone of any functional foods diet.
Leafy greens and flavonoids
Leafy greens are an excellent source of flavonoids, a group of plant compounds that have powerful anti-inflammatory effects on the body. Flavonoids can be found in a variety of foods, but leafy greens are particularly rich in these important phytonutrients. Flavonoids have been shown to reduce inflammation, boost immune function, and improve overall health.
One of the key benefits of flavonoids is their anti-inflammatory effects. Chronic inflammation is associated with a range of health problems, including heart disease, diabetes, and cancer. Flavonoids help to reduce inflammation by neutralizing harmful free radicals in the body, promoting the production of anti-inflammatory cytokines, and suppressing pro-inflammatory enzymes.
Flavonoids can also enhance immune function by boosting the activity of white blood cells, which are responsible for fighting infection and disease. This can help to reduce the risk of infections and improve overall health.
In addition to these benefits, flavonoids have been shown to have neuroprotective effects, which can help to protect against cognitive decline and neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Flavonoids also improve cardiovascular health by reducing oxidative stress, promoting healthy blood flow, and lowering blood pressure.
Now let’s take a look at some functional foods that are particularly important for bone health.
