Creatine: Worth It or Overhyped? 💪

Creatine isn’t just for athletes; it’s one of the most studied supplements in clinical nutrition.

🧠 What it does:
• Supports energy production (ATP) in muscle and brain cells
• Improves strength, recovery, and muscle mass
• May aid cognition, fatigue resistance, and healthy aging — meaning maintaining muscle, mobility, and brain function as we grow older, not just extending lifespan

🍽 Food vs supplement:
A normal diet with 4–6 oz of meat or fish per meal gives only 1–2 g of creatine daily, and cooking can cut that in half. Most studies use 3–5 g/day, so diet alone rarely provides enough.

⚠️ Use with caution if you have:
Kidney or liver disease | Diabetes | Heart failure | Dehydration | Are pregnant/breastfeeding | Take nephrotoxic meds.

☕ Caffeine: high doses may blunt absorption in some people.

🧬 Cancer: early studies show mixed results. Some data suggest creatine might increase tumor energy metabolism in certain cancers. Always review with your oncology team first.

Beans are going viral again. This time as
People are eating up to 2 cups of beans a day claiming better digestion, steady energy, and glowing skin. This includes soy beans, black beans, chickpeas, lentils, and kidney beans.

It’s not just hype. Studies show:
✨ Eating beans 4+ times/week = 22% lower risk of heart disease
✨ High bean + fiber diets = 25% lower risk of breast cancer
✨ Legumes also help reduce colon and prostate cancer, type 2 diabetes, and obesity risk.

Beans are packed with prebiotic fiber, plant protein, minerals, and antioxidants, all proven to support gut health, lower cholesterol, and reduce inflammation. 🌿

No wonder the longest-living people on Earth - from Okinawa to Sardinia - eat beans daily.

🥣 Try adding beans to chili, hummus, curry, soups, or salads. Start slow (½ cup a day) and work up to your comfort level.

💬 Want to know exactly how beans fit your goals?

You’ve probably heard: “Avoid soy if you have thyroid problems.”
But here’s the truth 👇

Soy itself doesn’t damage your thyroid! 💪
Research shows soy foods don’t lower thyroid hormones (T3 or T4). And that tiny rise in TSH some people get isn’t harmful.
🌏 In places like Japan, Korea, and Indonesia, people eat soy daily with no thyroid issues because their diets include enough iodine.

✅ If your thyroid is healthy:
Go ahead and enjoy soy!
Tofu, tempeh, soy milk, edamame, even every day, are fine when you’re getting enough iodine (from iodized salt or seafood).
Stick with whole soy foods and focus on balance, not fear. 🌿

⚠️ If you have hypothyroidism or take meds (like levothyroxine):
Soy doesn’t need to disappear, it just needs timing ⏰
💊 Take your thyroid pill on an empty stomach and wait about 3–4 hours before eating soy.
🧂 Keep iodine steady (iodized salt, seaweed, fish).
🥗 Stay consistent with how much soy you eat so your provider can adjust your dose if needed.

✨ Bottom line: Soy isn’t the problem - context is.
With the right timing and enough iodine, soy can fit beautifully into a thyroid-friendly diet. 💚

Your thyroid story is unique - your labs, meds, and lifestyle all matter.
Let Food RX Assistant help you personalize your eating plan if you have hypothyroidism.

It turns nutrition science into simple, everyday food choices that work for you.

Most multivitamins look impressive - long labels, bold claims, “ultra-premium” blends. But the truth is, many contain nutrients your body can’t absorb or don’t even list exact dosages.

Here’s how to make your multivitamin actually work for you:

1️⃣ Choose the right forms, not just high doses.
Your body absorbs some forms better than others:

B12: Methylcobalamin > Cyanocobalamin

Folate: Methylfolate > Folic acid

Magnesium: Citrate or Glycinate > Oxide
These forms are bioactive, meaning your body can use them immediately without extra conversion steps.

2️⃣ Check for quality and transparency.
Skip products that hide behind proprietary blends. You deserve to know what (and how much) you’re taking.
Look for a USP or NSF Certified seal. It means the supplement was tested for purity, potency, and contaminants.

3️⃣ Match it to your body, not the marketing.
Age, medications, genetics, and diet all change your nutrient needs.
For example, iron-free formulas may be better for men and post-menopausal women; vegetarians may need more B12 and zinc.
One size never fits all.

💡 Bonus: Taking your multivitamin with food and water helps absorption. Fat-soluble vitamins (A, D, E, K) absorb best with a meal that contains healthy fats.

If you’re unsure which formula fits your labs, diet, or health goals, don’t guess -

Olive Oil 101: When It Heals, When It Hurts

Not all oils are created equal. Even the healthiest ones can lose their healing power if used the wrong way.

Extra-virgin olive oil (EVOO) is rich in polyphenols and oleic acid, compounds that calm inflammation, support heart health, and protect your cells from oxidative stress. But when it’s overheated past its smoke point (around 375 °F), those same protective compounds start to break down. The result? Smoke compounds -oxidized fats and free radicals that do the opposite of what you want.

✨ Use it right:

Drizzle it over salads, soups, and roasted veggies after cooking.

Keep bottles sealed, stored cool, and away from light - heat and air destroy antioxidants.

Choose cold-pressed, extra-virgin with a fresh, peppery taste. That “bite” means it’s packed with polyphenols.

🔥 Use another oil for high-heat cooking:
For searing, stir-frying, or oven temps above 400 °F, reach for avocado or grapeseed oil — a clean, neutral oil with a higher smoke point that won’t oxidize as easily.

🩺 Bottom line:
It’s not just what oil you use — it’s how you use it that turns food into medicine. Small daily choices like this protect your heart, your brain, and your longevity.

Not all “nutrition experts” are the same.

👩‍⚕️ Registered Dietitians (RDs) complete years of university study, 1,000+ hours of supervised training, and national licensing exams - just like other healthcare professionals.

The title “nutritionist” isn’t regulated in most states. It can mean anyone - from a vitamin salesperson to an influencer with no formal training.

💡 That’s what sets Food RX Assistant apart.
Built by a Registered Dietitian, it gives you evidence-based answers you can trust, not generic internet tips.
