A fruity smoothie that gets its protein boost from powdered pasteurized egg white — an ingredient safe to drink without cooking and low in phosphorus — making it a fitting drink for anyone who needs extra protein without a heavy mineral load. We cut the sugar from the original and let the sweetness of pineapple in its own juice carry the drink.
Most smoothies raise their protein with yogurt, milk, or whey powder — all doorways to phosphorus that do not suit someone with tired kidneys.
This recipe from DaVita's renal kitchen sidesteps the problem with powdered pasteurized egg white: a near-pure protein that dissolves in the blender and leaves no trace in the taste. We kept the idea as it is, and cut the sugar from the original tablespoon down to a teaspoon, since canned pineapple in its own juice is sweet enough.
Wash the fresh strawberries, remove their green tops, and halve them; if they are frozen, use them as they are — they give the drink chill and body. Measure the pineapple as chunks with some of its natural juice.
Put the strawberries and the pineapple with its juice in the blender and blend on high speed for about 30 seconds until the mixture is smooth with no visible pieces.
Add the pasteurized egg white powder and the sugar and blend for another 30 seconds until the powder dissolves completely and the drink rises with a light, dense foam — the foam is a sign the protein has dissolved, not a flaw.
Pour the smoothie into a glass and drink it cold as soon as it is made — left standing, its foam collapses and its layers separate.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.

The most common problems when preparing Strawberry Pineapple Smoothie with Egg White Protein, and how to fix them:
It was added before the fruit was blended, or all at once over still liquid. Blend the fruit first until it flows, then add the powder while the blender is running — it dissolves in seconds.
It is the nature of egg white to froth when whipped. Let the glass sit for a minute before drinking and the foam settles, or shorten the second blend to 20 seconds.
The strawberries were not fully ripe. Add a piece of pineapple with its juice rather than more sugar — the sweetness comes from the fruit first.
Use frozen strawberries instead of fresh, or add two ice cubes while blending — the cold thickness comes without any nutritional addition.
Drink it as soon as it is blended; it contains dissolved egg white and does not tolerate standing long outside refrigeration.
Keep in a sealed container for 12 hours at most, shaking before drinking — though it is best made fresh each time, as the quantity is a single glass anyway.
| Original Ingredient | Tested Substitute | Ratio | Flavor Difference |
|---|---|---|---|
| Powdered pasteurized egg white | Liquid pasteurized egg white (carton) | 6 tablespoons (90 ml) | The closest substitute, with the same safety and protein; it thickens the drink slightly, so reduce the pineapple juice or add ice. |
| Pasteurized egg white | Whey protein powder | 1 small scoop (15 g) | An option for non-kidney patients only; whey protein is derived from dairy and higher in phosphorus, so the drink loses its renal advantage. |
| Canned pineapple in its juice | Fresh pineapple with cold water | 1/2 cup chunks (80 g) + 1/4 cup water (60 ml) | A cleaner flavor and slightly less sweetness, with comparable mineral values. |
| Sugar | Leave it out entirely | Omit 4 g | With ripe fruit the tongue does not miss it — the best choice for anyone managing both kidney disease and diabetes. |
| Quantity | Pineapple with juice | Strawberries | Egg white powder |
|---|---|---|---|
| 1 glass (the recipe) | 1/2 cup (125 g) | 1/2 cup (75 g) | 2 tablespoons (14 g) |
| 2 glasses | 1 cup (250 g) | 1 cup (150 g) | 4 tablespoons (28 g) |
| 4 glasses | 2 cups (500 g) | 2 cups (300 g) | 8 tablespoons (56 g) |
Make sure the package explicitly says "pasteurized egg white" — this alone is safe to drink without cooking, because the heat of pasteurization has killed any salmonella raw eggs might carry. Fresh egg white from the shell never goes into a smoothie. And choose canned pineapple "in its natural juice," not in sugary syrup.
