Psoriatic arthritis (PsA) is a condition where our body's immune system mistakenly targets healthy cells, often appearing alongside psoriasis. Beyond skin symptoms, it can impact our joints, internal organs, and even our eyes. It's worth noting that its signs can resemble other conditions, so pinpointing a diagnosis can be a bit of a puzzle.
Navigating life with PsA is a unique journey for everyone. Whether you're new to the diagnosis or have been managing it for some time, having the right information and support is invaluable. Dive into our site for insights on PsA, from understanding the diagnosis to exploring treatments. Alongside, discover tips for daily management, and avenues to advocate not just for yourself but for others too.
If you've been wondering why you feel more tired, achy, or foggy despite trying to eat well, the answer might be hiding in plain sight on your kitchen shelves. Four common food categories are silently accelerating the aging process, contributing to everything from joint pain and brain fog to increased risk of heart disease and diabetes.
The surprising reality: Many foods marketed as "healthy" or "natural" are actually loaded with the very ingredients that make you look and feel older than your biological age.
What they really are: Any food that's been significantly altered from its natural state through industrial processing, packaging, or preservation.
2025 Research Alert: A groundbreaking study published in the Journal of the American Geriatrics Society this year followed 15,000 adults over age 50 for eight years. Those who ate the most processed foods experienced:
32% faster cognitive decline
28% higher risk of developing diabetes
45% increased inflammation markers
Biological aging accelerated by 2-3 years
Hidden processed foods you might not suspect:
Flavored yogurts (often 15+ grams of added sugar)
Whole grain breads (loaded with preservatives and sodium)
"Healthy" frozen meals (sodium bombs in disguise)
Granola bars (sugar and artificial ingredients masquerading as health food)
Pre-made salad dressings (high in sodium and preservatives)
Real-life impact: Patricia, age 72, switched from processed convenience foods to simple, whole foods and reports: "My energy came back, my joint pain decreased, and I lost 18 pounds without trying. I wish I'd known about this years ago."
What they really are: Any sweeteners added during processing or preparation, different from natural sugars found in fruits and vegetables.
The Aging Acceleration Effect: Added sugars trigger a process called "glycation," where sugar molecules bind to proteins and fats, creating harmful compounds called AGEs (Advanced Glycation End Products). These literally age your body from the inside out.
2025 Discovery: New research from Harvard Medical School shows that people over 50 who consume more than 50 grams of added sugar daily (about 12 teaspoons) show:
Premature skin aging equivalent to 5-7 extra years
Accelerated brain shrinkage normally seen in much older adults
Weakened immune system making them more susceptible to illness
Sneaky sugar hideouts:
Pasta sauce: Up to 12g per serving
Bread: 2-4g per slice
Low-fat yogurt: 15-20g per container
Cereal: 10-15g per serving
Condiments like ketchup: 4g per tablespoon
The Hidden Names Game: Sugar appears on labels under 60+ different names including high fructose corn syrup, agave nectar, brown rice syrup, and even "natural" options like coconut sugar.
What they really are: Grains that have been stripped of their fiber, vitamins, and minerals, leaving only the starchy core that quickly converts to sugar in your bloodstream.
Why they're particularly harmful after 50: As we age, our metabolism naturally slows and our insulin sensitivity decreases. Refined carbs make this worse by:
Creating dramatic blood sugar spikes and crashes
Promoting fat storage, especially around the midsection
Increasing inflammation throughout the body
Contributing to insulin resistance and diabetes risk
Latest 2025 Research: A study from the Mayo Clinic found that adults over 55 who replaced refined carbs with whole grains experienced:
30% improvement in energy levels
25% reduction in belly fat
Significant improvement in memory and focus
Better sleep quality and mood stability
Common refined carb culprits:
White bread, pasta, and rice
Most breakfast cereals
Crackers and pretzels
Pastries and baked goods
Many "wheat" breads (often just white bread with caramel coloring)
What's considered excessive: The American Heart Association recommends no more than 2,300mg daily for most adults, but ideally 1,500mg for those over 50.
The aging connection: Excess sodium doesn't just affect blood pressure – it accelerates aging in multiple ways:
Dehydrates cells making skin look older and organs work harder
Increases inflammation throughout the body
Strains kidneys reducing their ability to filter toxins
Affects brain function contributing to cognitive decline
Breaking News 2025: Research from Johns Hopkins reveals that people over 60 consuming high-sodium diets showed brain changes similar to Alzheimer's patients, even without the disease.
Shocking sodium sources:
Restaurant soup: 1,000-2,000mg per bowl
Deli meat: 500-1,000mg per serving
Canned vegetables: 300-600mg per serving
Bread: 100-200mg per slice (adds up quickly!)
Cheese: 150-400mg per ounce
The Perfect Storm Scenario: Many older adults unknowingly consume all four food villains in a single meal:
Breakfast: Processed cereal (refined carbs + added sugar) with toast (more refined carbs + sodium) and orange juice (added sugar)
Lunch: Deli sandwich (processed meat + excess sodium + refined bread) with chips (sodium + processed)
Dinner: Frozen meal (processed + sodium + added sugars + refined carbs)
The result: Chronic inflammation, energy crashes, weight gain, brain fog, and accelerated aging – all from foods that seem "normal."
"Health halo" foods use clever marketing to seem healthy:
"Multigrain" (often just refined grains mixed together)
"Natural flavors" (can include 100+ chemical compounds)
"No high fructose corn syrup" (may contain other harmful sugars)
"Reduced sodium" (still might be very high in salt)
Modern life pressures make processed foods seem necessary:
Time constraints leading to quick meal solutions
Marketing that positions processed foods as "family-friendly"
Addictive nature of sugar/salt/fat combinations
Lack of cooking skills or confidence
Instead of frozen meals → Try: Batch cooking simple recipes on Sunday
Cook a big pot of vegetable soup
Roast a sheet pan of mixed vegetables
Prepare brown rice or quinoa in bulk
Instead of processed snacks → Try:
Apple slices with natural almond butter
Hard-boiled eggs with cherry tomatoes
Plain Greek yogurt with fresh berries
Instead of sweetened yogurt → Try: Plain yogurt with fresh fruit Instead of sugary cereals → Try: Oatmeal with cinnamon and berries Instead of fruit juice → Try: Water infused with fresh fruit slices Instead of store-bought salad dressing → Try: Olive oil and lemon juice
Instead of white bread → Try: Sprouted grain bread (check ingredients!) Instead of white rice → Try: Brown rice, quinoa, or cauliflower rice Instead of regular pasta → Try: Whole grain pasta or zucchini noodles Instead of crackers → Try: Sliced vegetables with hummus
Instead of canned soup → Try: Homemade soup (freeze portions) Instead of deli meat → Try: Grilled chicken breast (cook extra for later) Instead of seasoning salt → Try: Herbs, spices, lemon juice, or vinegar Instead of restaurant meals → Try: Home cooking with herbs for flavor
What's driving the change: More older adults are demanding transparency in their food choices, leading to:
Increased availability of minimally processed options
Better labeling requirements
More grocery stores offering "clean" sections
Restaurant chains providing detailed nutritional information
Technology helping: New smartphone apps can scan barcodes and instantly reveal hidden sugars, sodium levels, and processing levels in foods.
"I thought my constant fatigue was just part of aging. After eliminating processed foods and reading labels carefully, my energy returned. I feel like I'm 60 again, and my doctor is amazed by my improved blood work."
"My blood pressure was creeping up despite medication. When I cut back on hidden sodium sources, it dropped 20 points. I realized I was getting over 3,000mg of sodium daily just from 'healthy' foods."
"I was addicted to diet sodas and low-fat processed foods. Once I understood how artificial ingredients were affecting my mood and sleep, I made the switch to whole foods. The brain fog lifted within two weeks."
