|Yes, blueberry smoothies are heart healthier than those without blueberries, but can't replace blood pressure meds.|
I will try to adapt the length of the summary to the appeal of the article, but if you feel that a specific topic has not been covered "in-depth enough" for your liking, you can always type the title of the study from the references into google and take a closer look, yourself.
- We don't see the dietary mistakes we make (Sproesser. 2015) - In contrast to our perception of physical weaknesses like love-handles and co our perception of our eating habits is often not critical enough. According to a recent study from the University of Konstanz in Germany, people considered what they ate always healthier than what others ate, even if an objective assessment said that there were no significant differences.

the meals for themselves and their peers (Sproesser. 2015).
- Egg yolk protein delays, egg ovalbumin (the white stuff) boosts the recovery of your iron levels (Kobayashi. 2015) - In spite of the fact that the study at hand was conducted in female rats, it's safe to assume that the yolk and white protein will have different effects on iron absorption and thus the the induction of iron deficiencies in man and women on low iron diets, too.

- Blueberries are good for the heart, but they are no replacement for your blood pressure meds (Stull. 2015) - ed. In a recent double-blind and placebo-controlled study was conducted in 44 adults (blueberry, n = 23; and placebo, n = 21). The subjects were randomized to receive a blueberry or placebo smoothie twice daily for six weeks.

Accordingly, the study does support the notion that eating blueberries - even in form of a smoothie - can have beneficial effects on your heart health. In view of the fact that in this particular study a comparison of no-blueberry vs. blue-berry smoothies was conducted, you could also argue that the inclusion of blueberries in a smoothie may smooth out the negative effects of another (unnecessary) snack on your health and suggest: If you want to eat blueberries don't add them as a snack, but use them as a replacement for other foods.
