Blueberries: Health Factor Profile and How to Eat Them Well

Blueberries deliver 14g of carbohydrate and 2.4g of fibre per 100g, with the standout being their anthocyanin content. These deep-blue polyphenols drive the inflammatory, vascular, and cognitive benefits documented across more than 200 randomised trials.

Glycaemic load is unusually low for fruit, around 5 per 100g, and clinical data shows blueberry polyphenols actively flatten the glucose response of co-eaten foods. Eating them alongside oats or yoghurt produces a measurably lower curve than the same meal without.

Vitamin C, manganese, and vitamin K round out the micronutrient profile, but the polyphenols are the reason this fruit appears so often in our protocols.

Dose matters. The clinical benefits show up at 150g per day, not at the 20g handful most people add to muesli. Treat them as a daily supplement-grade food rather than an occasional garnish.

Frozen is equal to fresh on every measurable nutrient. NZ-grown frozen blueberries from Pak'nSave or New World cost roughly half the fresh price and store for months. Thaw briefly or blend straight from frozen.

Pair with protein and fat for the steadiest glucose response. A bowl of Greek yoghurt, blueberries, and a tablespoon of Pic's peanut butter is one of the cleanest breakfasts we prescribe.

Blueberries appear in nearly every Longevity Programme and Functional Nutrition plan we run. The daily 150g dose is one of the simplest, highest-leverage interventions for clients with elevated inflammatory markers, cognitive complaints, or vascular risk factors.

They suit almost every client profile, including fat-loss clients who often fear fruit unnecessarily. Even at 150g daily, the calorie cost is around 85 kcal, easily offset by the polyphenol payoff.

The only exception is the rare client with confirmed salicylate sensitivity, where we substitute with green kiwifruit, also a strong NZ-grown polyphenol source.
