It is no longer news that a healthy and balanced diet is one of the primary keys to a healthy lifestyle. Our dietary choices significantly influence not only our physical appearance but also the functioning of our bodies. Did you know that opting for nutritious foods could potentially play an important role in delaying and preventing the progression of Alzheimer’s disease?
Alzheimer’s disease is a growing problem in the world today, affecting over six million adults in America alone. With these figures, it is crucial to prioritize choices that can help keep Alzheimer’s disease at bay, one of them being a good diet. That is why we have curated a selection of foods specifically geared towards protecting the brain and supporting Alzheimer's defense.
What is Alzheimer’s disease?
Alzheimer’s disease is a neurological disorder that is progressive and characterized by memory loss, cognitive decline, and changes in thinking abilities. It is the most common form of dementia, which is also a health condition that affects thinking, memory, and behavior. Alzheimer’s disease can be brutal to the extent to which it interferes with daily life, typically worsens over time, and can eventually lead to an inability to do even the simplest tasks.
While the cause of Alzheimer’s disease has not been fully understood, it is believed to involve a combination of genetic, lifestyle, and environmental factors. Alzheimer's mostly happens because of a buildup of abnormal protein deposits in the brain, including amyloid plaques, which interfere with communication between cells, leading to their gradual degeneration and ultimately death.
Although there is currently no cure for Alzheimer's, there are ways to manage, prevent, and slow down its progression. One of which is a diet that contains foods that offer protective properties to the brain. These foods contain powerful antioxidants, minerals, and vitamins such as B vitamins, flavonoids, polyphenols, protein, vitamins A, and E, and omega-3 fatty acids.
Eight foods for Alzheimer's defense
1. Bell peppers
With their crisp texture and vibrant colors, bell peppers are not only a great addition to a balanced diet but they can also offer protective properties to the brain. They contain an array of nutrients and powerful antioxidants that can help prevent cognitive decline and memory loss. Red bell peppers particularly contain more vitamin C than green bell peppers. Vitamin C aids the preservation of cognitive function and decreases the risk of neurodegenerative diseases like Alzheimer's. Bell peppers also contain vitamin E, another rich antioxidant that can help protect cell membranes from damage and support brain function.
The vibrant colors of bell peppers — orange, yellow, and red are attributed to carotenoid pigments such as zeaxanthin, beta-carotene, and lutein. These carotenoids possess antioxidant qualities that are associated with a decreased risk of cognitive decline and improved performance in aging adults. Moreover, bell peppers contain vitamin B6, which plays a major role in the synthesis of neurotransmitters that help in cognitive processes. Consuming foods rich in vitamin B6 like bell peppers can improve mental well-being and support cognitive functions.
2. Raspberries
Raspberries have a sweet-tart flavor that makes them an amazing summer treat for many. They are also packed with numerous antioxidants, vitamins, and minerals such as vitamin C, vitamin K, and dietary fiber. They are particularly rich in flavonoids such as catechins, anthocyanins, and quercetin, which can help eliminate oxidative stress, a process involved in the development of neurodegenerative diseases such as Parkinson’s and Alzheimer's.
Chronic inflammation is one of the notable culprits behind the development and progression of neurodegenerative diseases. The anti-inflammatory qualities in raspberries can help reduce neuro-inflammation, thereby promoting a healthier environment for the brain and promoting optimal cognitive function. The abundance of vitamin C in raspberries may help reduce the symptoms associated with cognitive decline. In addition, raspberries contain fiber that can improve the health of the gut microbiome, which can have a significant effect on the brain. Studies have shown that a healthy gut can play important roles in improving behavior, cognition, and mood.
3. Soybeans
Soybeans are versatile and are an excellent source of plant-based protein, providing the essential amino acids needed for repairing and building tissues including the ones in the brain. Moreover, protein is important for the synthesis of enzymes and neurotransmitters important for brain function. Soybeans also contain omega-3 fatty acids, which are important components of brain cell membranes and play an important role in neuroplasticity and neurotransmission.
Moreover, soybeans are loaded with isoflavones, a kind of phytoestrogen with estrogen-like effects on the body. The primary types of isoflavones found in soybeans, daidzein and genistein, can potentially offer neuro-protective properties to the brain. In addition, soybeans contain antioxidants such as selenium, vitamin E, and phenolic compounds that can help protect the brain from cell damage and inflammation associated with Alzheimer’s disease.
4. Barley
Barley is a nutritious and versatile cereal grain that is rich in numerous phytonutrients, minerals, and vitamins. Due to its high fiber composition, barley can aid the regulation of blood sugar thereby reducing the risk of impaired cognitive function and dementia. By boosting stable blood sugar levels, barley can help maintain cognitive function.
Furthermore, barley contains phytonutrients and antioxidants that can help reduce inflammation thereby protecting brain cells from damage and reducing the risk of cognitive decline. Barley also contains nutrients such as magnesium, folate, and vitamin B6 that play major roles in brain functions. These nutrients are beneficial for DNA repair and energy metabolism. By providing the brain with these rich nutrients, barley can support optimal brain performance and help prevent Alzheimer’s disease.
5. Turmeric
The primary active compound in turmeric responsible for its health advantages is curcumin. Curcumin may boost neurogenesis, the development of new neurons in the brain. This process is particularly essential for improved brain health and immunity against neurological disorders. Additionally, curcumin can serve as a powerful antioxidant because it has strong anti-inflammatory qualities, which are beneficial for brain health.
The buildup of beta-amyloid plaques in the brain is one of the features of Alzheimer’s disease. Curcumin can potentially help to clear these plaques, which may help slow down the progression of Alzheimer’s disease and reduce negative effects on cognitive function. Curcumin can also protect the brain from neurotoxicity including those caused by chemicals, oxidative stress, and heavy chemicals. By protecting the neurons in the brain, curcumin can help maintain brain function and help prevent brain diseases such as Parkinson's and Alzheimer’s.
6. Walnuts
If you are looking for a healthy snack to add to your diet, try walnuts! Walnuts contain omega-3 fatty acids that are beneficial to brain health as they play an important role in the function and structure of brain cell membranes. Consuming foods like walnuts that are high in omega-3 fatty acids may help offer protection against age-related cognitive decline. Walnuts also contain diverse antioxidants such as polyphenols and vitamin E, which can help fight and protect the brain from inflammation. The polyphenols in walnuts can also help boost blood flow to the brain and enhance the signaling pathways of the brain.
By improving blood flow to the brain, walnuts help ensure that the brain gets an adequate supply of nutrients and oxygen, which is crucial for overall brain health. Including walnuts in a balanced diet can help boost brain health, help prevent brain decline, and strengthen the brain’s defense against diseases.
