Creatinine levels dropped from 7.1 to 0.9 in 2 days! 4 healthy fats for kidney health and 4 potentially risky fats you should know about. 👇👇

A creatinine drop from 7.1 to 0.9 mg/dL in just 2 days sounds dramatic — but let’s be clear: such a rapid change is uncommon and usually happens only in specific medical situations (like dehydration being corrected, lab error, or emergency treatment such as dialysis). If creatinine was truly 7.1, that level is considered dangerously high and requires medical supervision.

Now, let’s talk about fats and kidney health 👇

đŸ„‘ 4 Healthy Fats That May Support Kidney Health

These fats can help reduce inflammation, support heart health (very important for kidney patients), and improve overall metabolic balance:

1. Extra Virgin Olive Oil

Rich in monounsaturated fats and antioxidants, olive oil may help reduce inflammation and support cardiovascular health — a major concern in chronic kidney disease (CKD).

2. Avocados

Packed with healthy fats and fiber. However, if you have advanced kidney disease, be cautious because avocados are high in potassium.

3. Fatty Fish (Salmon, Sardines, Mackerel)

High in omega-3 fatty acids, which may help lower inflammation and protect blood vessels. Omega-3s are often recommended in kidney-friendly diets.

4. Nuts (Especially Walnuts & Almonds)

Provide healthy fats and plant-based nutrients. Portion control is important since they are calorie-dense and contain phosphorus.

⚠ 4 Fats That May Be Risky for Kidney Health

These fats can worsen inflammation, raise blood pressure, or increase cardiovascular risk — all harmful to kidney function:

1. Trans Fats

Often found in processed snacks, baked goods, and fried fast food. These increase inflammation and heart disease risk.

2. Processed Vegetable Oils (Highly Refined)

Oils high in omega-6 fatty acids (like some corn or soybean oils) may promote inflammation when consumed excessively.

3. Deep-Fried Foods

Contain oxidized fats that stress blood vessels and increase cardiovascular risk.

4. Processed Meats with Added Fats

High in saturated fat, sodium, and preservatives — harmful for both blood pressure and kidney function.

🚹 Important Reminder

Creatinine levels reflect kidney filtration (GFR). While diet plays a role in long-term kidney health, no specific fat will magically drop creatinine in 48 hours. Sudden large changes usually indicate:

  • Acute kidney injury recovery

  • Dialysis treatment

  • Lab variation

If someone had a creatinine of 7.1, they should be under medical care immediately.
