Rxbar Blueberry, Mixed Berry Protein Bar: Food Integrity analysis
Quick answer
High integrity
Rxbar blueberry, mixed berry protein bar received a Food Integrity Score of 84 out of 100 (high integrity). This reflects lightly processed and low additive load. The list is short and mostly recognizable, built around dates, egg whites, nuts, and fruit. The two natural flavor entries are the main reason for caution, since they hide what is actually in the flavor blend. This reads as a reasonable occasional snack that is simpler than many bars, though a whole-food version would be a cleaner everyday choice. Main considerations include two vague natural flavor entries and flavor sources not disclosed. Simpler options: Choose bars that name specific flavor sources instead of natural flavors; blend dates, nuts, and berries at home for a fully whole-food version.

Blueberry, Mixed Berry Protein Bar

High integrity
Warning Signs
Natural flavors appear twice, leaving the actual flavor source vague in this bar.
Consider This
Natural flavors and a short list of nut and fruit ingredients suggest a lightly formulated bar rather than a whole-food snack.
Good Substitutes
Whole nuts, dates, and berries blended together at home give a similar profile with no flavor system.

Understanding the Food Integrity analysis
What the Food Integrity analysis evaluates
The Food Integrity analysis focuses on how a packaged food is formulated and made. It examines processing level, ingredient quality, additives, oils, sweeteners, purity cues, and how clearly a label communicates what is in the product. The Food Integrity Score summarizes that formulation and transparency picture on a 0–100 scale. It is not a full nutrient report and it is not a personalized meal plan.
Why processing, ingredients, and transparency matter
Processing level and ingredient quality shape what you are actually eating beyond calories on the label. Additives, industrial oils, and intense sweeteners can change how clean or heavily engineered a product feels, even when the front of pack looks wholesome. Purity and transparency matter because incomplete or marketing-heavy labeling can hide tradeoffs that only show up when the full ingredient list is reviewed carefully.
Who may prioritize Food Integrity
Some people care mainly about Food Integrity because their dietary goals center on formulation rather than macros alone. Examples include checking vegetarian or vegan suitability, preferring simpler ingredient sources, avoiding certain additives or sweeteners, watching oil choices, or preferring less processed options. For those priorities, the Food Integrity Score can be the more practical first read.
How Food Integrity differs from Longevity
Food Integrity is the focused analysis of processing, ingredients, additives, purity, and transparency. Longevity is the broader analysis of nutritional composition, metabolic and dietary characteristics, processing, and ingredient quality together. Favorable nutrition values do not necessarily mean strong Food Integrity: a product can look balanced on macros yet still rely on heavy processing or additives that the Food Integrity analysis flags in more detail.
Why the two analyses overlap—and why to review Longevity too
The analyses overlap intentionally. Food Integrity–related characteristics contribute to Longevity, and Longevity still benefits from the same ingredient-quality lens. They are not competing verdicts; they answer different questions at different depths. Reviewing the Longevity analysis can add information about nutritional composition, metabolic characteristics, and dietary balance that Food Integrity alone does not emphasize. Looking at both usually gives the most complete understanding of tradeoffs.
Common questions about this product
Is Rxbar Blueberry, Mixed Berry Protein Bar highly processed?
Food Integrity lists processing level as Lightly processed. That reflects formulation and processing signals from the ingredient analysis — not a medical or regulatory classification.
Why are the Longevity and Food Integrity scores different?

Rxbar Blueberry, Mixed Berry Protein Bar shows about 4g of fiber per labeled serving in the Longevity nutrition facts.
Does it contain added sugar?
Rxbar Blueberry, Mixed Berry Protein Bar: 0g added sugar per serving; sweetener signals include dates (natural fruit sugar). Confirm the current package Nutrition Facts and ingredient list.
What helped the Longevity Score?
Key positives called out in the analysis include: Short ingredient list of whole foods; 12g protein and 4g fiber per bar; No artificial colors or sweeteners.
What prevented a perfect Longevity Score?
Key concerns noted include: Dates contribute 15g sugar per bar; Calorie-dense at 210 kcal per serving; Contains natural flavors.
