Heart HealthHeart Healthy Tips – Berries and Your Heart Health
In the battle against chronic disease, specifically heart disease, the antioxidant content of berries is a fantastic weapon.
Researchers in 2008 studied 72 volunteers over an eight week period. The volunteers were divided into a berry group and control group. The berry group was fed 100 grams of whole bilberries, 50 grams of lingonberry-rich nectar, and 100 grams of blackcurrants, strawberries, or raspberry-chokeberry juice every other day. The control group received non-berry “fruit placebos”, such as sugar water and marmalade. After 8 weeks, the berry group had an increase in HDL cholesterol of 5.2%, decreased blood pressure, and improved platelet function.
Berries are a great source of antioxidants, which prevent cell damage by eliminating free radicals. One visible piece of evidence indicating the powerful antioxidants within berries is their color. Berries are rich in phenolic compounds called anthocyanins, which give berries their deep red and blue colors.
Tired of changes that don't last?
A word of caution! There has been a recent media frenzy over certain berries as “superfoods”. There is currently no scientific proof that higher antioxidant levels of certain berries correspond to improved health benefits that justify the inflated price tags. Some studies on antioxidants have given disappointing and unexpected results. But regardless, even if berries are not a “miracle cure”, they are rich in fiber, vitamin C, manganese, folate, and potassium, and are an important part of a heart healthy diet.

Where I send people for supplements
Food first, always. When a supplement is worth considering, the front of the bottle is marketing and the supplement facts panel is the actual content. Two bottles at the same price can differ by half in what they deliver.
My dispensary carries practitioner-grade products, most of which aren’t sold direct to consumers, with the reasoning behind each one.
