Wikipedia seems to claim the latter, while other sites claim they are extremely high in nutrients.
Water, sugar, and fibre? Sure.. but it’s not about the macros with blueberries. It’s definitely about the micro’s.
Anti-aging, anti-inflammatory, brain healthy (memory loss benefits), parkinsons prevention, cancer prevention, eye health, heart health, blood pressure reduction and more.
Google is your friend in this case!
Blueberries, along with other berries like raspberries, blackberries, etc are my preferred fruit in terms of nutritional value. They also have increased fiber. The fiber these berries (low to mid 4+ grams/serving) contain works to give a steady stream of sugar energy, which is why I prefer these Xberries to apples, oranges, strawberries, and bananas - who have less fiber (each clocking in at low 2 grams of fiber/serving).
At the end of the day though if you’re eating whole fruit (not drinking fruit juice) instead of a processed food snack, you’re doing great.
You are filling up on water and fiber. There are very few calories in 40 blueberries, maybe 30 calories.
Eat them all day and see if you can reach your normal calorie intake for the day. Most people are satisfied, hunger-wise, and stop eating fruits well below what would be considered a normal daily calorie level.
The fruit diet is known to facilitate weight loss.
But a constant energy source of fruit fructose sugars is not healthy either. So moderation with any fruit should be pursued as an assist to lowering total calorie count for the day and losing weight.
A straight constant fructose diet can become very unhealthy over time. The liver will become stressed and can fail over time because it must convert fructose to glucose/sugar.
The constant spikes in insulin are not healthy either as fructose is not absorbed slowly, but quickly, causing insulin spikes, as opposed to healthy/minor elevated insulin levels covering a longer period of time.
