Foods to eat and avoid to manage geographic atrophy

Geographic Atrophy (GA) is an advanced form of age-related macular degeneration (AMD), which leads to irreversible vision loss. As its name suggests, it directly affects the macula, the part of a person’s eye responsible for central vision. While currently, there is no known cure for geographic atrophy, there is a proactive approach that people can take to delay its progression. This includes altering nutritional intake, adding some foods to the daily routine, and subtracting others.

Foods to eat for geographic atrophy

Leafy greens
Leafy greens like spinach, kale, lettuce, and Brussels sprouts are rich in lutein and zeaxanthin, two powerful pigments, in high amounts of leafy greens. These pigments are powerful antioxidants that can help protect the macula, the central part of the retina affected by GA. An excellent way to incorporate these leafy greens into the nutritional routine is by adding them in salads, smoothies, or lightly sauté for a side dish.

Green vegetables
Besides leafy greens, the pigments lutein and zeaxanthin are also found in high amounts in other green vegetables, such as avocados, green bell peppers, peas, and broccoli. These vegetables can also be easily included in salads or other sandwiches. Avocados can also be added to smoothies, spinach, and kale to make it even better for the eyes.

Fatty fish
Fatty fish such as salmon, mackerel, tunas, and sardines are high in omega-3 fatty acids, which have anti-inflammatory properties. So, including these in the meal plan may also help reduce the risk of geographic atrophy progression. These fatty fish can be grilled or baked twice weekly to reap the benefits.

Colorful fruits
Like green vegetables, the pigments of lutein and zeaxanthin are also present in yellow, orange, and other colorful fruits. These include oranges, strawberries, pomegranates, and grapes, among others. Oranges also contain high amounts of vitamin C, essential for maintaining eye health. Pomegranate is a powerhouse of vitamins C and K and antioxidants, contributing significantly to eye health. Fresh fruits like oranges and strawberries can be consumed as snacks, salads, juices, or smoothies.

Berries
Berries such as strawberries, blueberries, blackcurrants, etc., are rich in antioxidants, which help slow down the GA progression. Berries, along with citrus fruits and leafy greens, are also rich in flavonoids, which help boost the retina’s health. They also contain a compound called anthocyanin, which is known to reduce inflammation and prevent the retina from undergoing degenerative changes. Berries can be easily consumed as snacks or added to yogurts and smoothies.

Carrots
Carrots are a superfood for the eyes. Along with the pigments lutein and zeaxanthin, they also contain beta-carotene, which significantly supports eye health and helps slow down the progression of geographic atrophy. Carrots can also be included in salads, meals, or in smoothies.

Nuts and seeds
Nuts like almonds, walnuts, chia seeds, and flaxseeds are rich in vitamin E and omega-3 fatty acids. These compounds also contribute to overall eye health. One can add a handful of nuts or seeds to their morning cereal or yogurt or munch on them as a snack.

Corn, tomatoes, and pumpkins
Corn, tomatoes, and pumpkins are all rich in the pigment carotenoid, which aids in reducing the GA progression. Tomatoes are also rich in flavonoids and vitamin C, which adds to the benefits. All of these foods can be added to cooked meals or salads.

Foods to avoid for managing geographic atrophy

Foods with high saturated and trans fats
High intake of saturated and trans fats can increase the risk of age-related macular degeneration (AMD), further posing the risk of geographic atrophy. These compounds are often found in processed and fried foods. Hence, for people with the risk of AMD or GA, limiting the consumption of fried foods, fast food, and commercially baked goods high in unhealthy fats is crucial.

Excessive sugar
Foods high in sugar and refined carbohydrates may lead to inflammation, which can worsen geographic atrophy. So, those at risk need to cut back on sugary snacks, beverages, and excessive desserts. When they crave something sweet, they can instead consume the fresh fruits and berries mentioned above (oranges, blueberries, etc.). This way, not only will they avoid risky foods, but they will also proactively aid their body in reducing the risk of GA progression.

High sodium foods
High sodium intake can contribute to high blood pressure, a risk factor for AMD and GA progression. So, people at risk should reduce their consumption of salty processed foods like chips and canned soups.

Processed meats
Processed meats like hot dogs and bacon contain unhealthy fats and preservatives that may harm eye health. Instead of processed meats, one can opt for lean, unprocessed proteins like chicken, turkey, and tofu.

Dairy products
Some studies have suggested that high consumption of dairy products, particularly full-fat dairy, may be associated with an increased risk of AMD progression. Hence, to be safer, those at risk should consider reducing their full-fat milk, cheese, and butter intake. They can opt for dairy alternatives like almond, oat, or soy milk if they prefer a milk substitute.

Along with making dietary changes, having a healthy lifestyle is also a prerequisite to managing this condition. One must follow a strict meal plan and adhere to the foods mentioned above to eat and avoid for better results. Furthermore, following a stringent exercise routine will also yield good results.

While geographic atrophy can present significant challenges, making informed choices in food regimens can help manage its progression and promote better eye health. Incorporating nutrient-rich foods and avoiding those that may exacerbate the condition is a positive step toward maintaining the vision. One must consult their healthcare provider for further information regarding the condition and nutritional changes. One can also be informed about any supplements that can be taken or if they should be avoided.

Top 6 foods that may reduce dementia risk

Many individuals mistakenly believe that dementia is a disease, but it’s a term used to describe symptoms related to memory, social abilities, and thinking. These symptoms can be challenging to manage and can impact daily activities. However, healthcare professionals often recommend implementing a healthy meal plan as a way to improve management. If you’re interested in learning about how your food intake can reduce the risk of developing dementia, read on. What is dementia? As previously mentioned, dementia is not a specific disease. Instead, health conditions like Alzheimer’s disease are among its most frequent causes in older adults. Other known causes of dementia include damage to the blood vessels that supply nutrients to the brain, the formation of balloon-like proteins in the brain, and the breakdown of connections and nerve cells in the brain. While memory loss is one of its most recognizable signs, this symptom alone does not mean one has dementia. Most symptoms of this group of health issues can vary depending on the cause. Hence, here are some of the most common signs to look out for. Memory loss Difficulties while communicating Reasoning and problem-solving issues Poor control of movements and coordination Disorientation Confusion What are the foods that can help reduce the risk of dementia? Typically, dementia and Alzheimer’s are known to be caused by a combination of several factors, such as environmental, lifestyle, and genetic. Furthermore, developing issues such as high blood pressure, diabetes, and heart disease can contribute to cognitive decline in patients. Therefore, healthcare professionals suggest the consumption of nutrient-rich foods to reduce dementia risk as one grows older. Some of the foods that can be added to one’s meal plan are: Avocados Avocados are one of the most commonly known superfoods, which can provide the brain with the needed energy without a spike in blood sugar levels.

Avoid these 15 common shower mistakes

There is nothing a warm shower cannot resolve. Showering after a long day can be a stress reliever and enhance one’s mood instantly. It also has several other health benefits besides cleansing the body, including facilitating cold relief, boosting immunity, and relieving muscle pain. However, not bathing the right way can give rise to skin conditions such as rashes and eczema. Here are some common mistakes one should avoid while bathing and showering: Not moisturizing after a shower Wiping after a bath can reduce the body’s moisture, causing dry skin, which can lead to rashes and itching. Dermatologists recommend applying body lotion and moisturizer immediately after a shower to retain skin texture and prevent dryness. One should look for hypoallergenic moisturizers that do not have any added fragrances. Bathing in scorching hot water Scorching hot water can damage keratin cells in the skin’s outer layer. Consequently, the skin becomes dry and dehydrated. It is important to balance the water temperature before stepping into the shower. Ideally, the temperature of the water should be lukewarm. Using the wrong towel An absorbent towel that does not feel rough is ideal for wiping oneself after a shower. The most effective way to select the right towel is to check its density, measured in grams per square meter (GSM). Towels with GSMs between 400 and 550 are considered ideal for use after bathing. One should avoid towels below a GSM of 400, as these towels can be thin and rough, causing skin dryness. Moreover, towels made of superior-quality Egyptian or Turkish cotton are extremely soft and perfect for the skin. Soaping the arms and legs excessively While it is important to wash and clean one’s arms and legs, these areas typically do not collect much oil and dust. Hence, scrubbing them excessively can dry out these areas and hamper their natural texture.

15 signs of a weak immune system

The immune system is a complex network of organs, cells, and proteins that act as the body’s defense mechanism against diseases and infections. The system —the innate immune system that people are born with and the adaptive immune system, which develops due to exposure to toxins and microbes. Both parts work together to keep infection-causing germs and toxins. So, weak immunity can make the body susceptible to diseases and other health issues. High stress levels The American Psychological Association suggests that chronic stress weakens the immune system. This is because stress lowers the number of white blood cells (i.e., lymphocytes) in the body that fight infections, increasing the risk of infections such as the common cold. Persistent cold Most adults develop two to three colds per year, which usually last from 7 to 10 days. During this period, the immune system forms antibodies to fight the virus. However, if one keeps catching a cold or is dealing with common cold symptoms for a long time, it could be a sign of weak immunity. Slow-healing wounds When one develops a cut or a wound, the body immediately goes into damage control mode to stop any bleeding and regenerate skin. Immune cells in the body guide this process. However, when dealing with a weakened immune system, wounds take longer to heal. This can make one more susceptible to infections as well. Frequent infections Those with a lowered immunity are at a higher risk of contracting infections such as pneumonia, meningitis, bronchitis, and skin infections. They are also more likely to experience autoimmune disorders, organ inflammation, blood disorders such as anemia, and growth and developmental delays. According to the American Academy of Allergy, Asthma, and Immunology, some signs of weak immunity include: – Having more than four ear infections in a year – Developing pneumonia twice within a year – Dealing with chronic sinusitis or more than three episodes of bacterial sinusitis in a year Fatigue If one constantly feels tired despite getting enough sleep, it may be a sign of weak immunity.
