Too much blending???
Hanawaiman6358 posted:
I have been battling hypertension since March. It has been successful going from 170/100 to 118/72 or there abouts. I have accomplished this by the Esse, Fuhrman plan. No salt, including sodium free baking powder. But I have a question; I notice that after I drink one of my massive smoothies (2 bananas, 1 cup cooked lentils, 2 fresh peaches, 1 cup blueberries, 2 cups non fat soy milk, and some added "sugar"), my BP goes up to 140/85 for about half a day. Anyone hear of such a thing? What could cause that? My fasting blood glucose is 91. I hate to give it up, it is so good.

Hi Hanawaiman6358,

Great to have you aboard. Thanks for the interesting post.

Congratulations on your success lowering your blood pressure. You are clearly doing great, and you know it wasn't always easy. Great work !! :-)

We tend to use the blended stuff as a way to eat more greens, and increase nutrient absorption from the blending. The blending breaks open the the plant cell walls, and increases nutrient absorption.

Everything in your blended mix is healthy, but does not need to be blended to be absorbed. Lentils are super healthy, as are all beans. No need to blend them. Lentils have one of the lowest glycemic index values. Blending them will increase the glycemic index. Fruit is excellent. No need to blend fruit to increase absorption.

Our smoothies are mostly greens and veggies: romaine lettuce, carrots, kale, spinach, bok choy, nuts, seeds, and enough fruit to make it palatable. Broccoli, cauliflower, collard greens, etc have a stronger flavor. My fruit is typically 1/2 banana, 1/2 box raisins (1.5 oz box), 2 prunes, and if available, strawberries, raspberries. Any fruit is fine. My mix is only slightly sweet. About 5 or 6 cups.

Your blended mix is a very sweet mix, plus has sugar added. We are alike in that we both have sweet tooths. If you are still short of your health goals, one thing to consider is to increase veggies and wean away from sweets. Whole fruit is excellent, but consider using whole fruit as your only sweetening. (No juice, for example, except pomagranate juice, if desired.) Now things are much sweeter to me. I used to use a little Splenda, but it stimulated me to over eat, so I gave that up. I save sweets for dates with my wife, where we plan a splurge. Just my thoughts.

Best regards, EngineerGuy

Drop the added sugar and see what happens.An increase in blood glucose can raise blood pressure....but I have found that fruits don't have this effect as does regular sugar.

I know some say sugar is sugar and fructose is fructose but in my experience there is a world of difference.
Hanawaiman6358 replied to jc3737's response:
Thank you for the suggestion. I will try it this afternoon.
Hanawaiman6358 replied to Hanawaiman6358's response:
Eliminating the sugar didn't to anything. My Theory: smoothie is about 800-1000 cal and since it is blended like a milkshake it pretty much bypasses my stomach and goes straight to small intestines where it is absorbed. There is a very quick absorption rate and this quick absorption directs an increase of blood flow to the digestion system and to accomplish that my BP goes up. Now how's that for a theory? Small smoothies don't raise BP.
jc3737 replied to Hanawaiman6358's response:
Could be......larger meals in general will tend to raise blood sugar(and blood pressure) more than smaller meals.
An_192712 replied to jc3737's response:
Hi folks,

I think you've nailed it on the head. The fruit and lentil smoothie just makes a very fast absorption.

A smoothie is a great way to eat a pound of raw veggies (greens, etc.) This is in addition to a large conventional salad, daily. This is the healthy benefit we are looking for.

No one minds your photo.One of these days I will take the time to figure out how to download a photo.
jc3737 replied to An_192712's response:
Every so often I dig into the research about raw vs cooked vegetables and blended vs unblended.I can't find any major advantage to any particular method.When I find differences in the data its very very minor differences.There are tons of studies about raw vs cooked but no definitive conclusion about which is best.

With some vegetables like carrots and tomatoes there is data that points to cooked as releasing more of the nutrient benefits and some studies show that raw vegetables have slightly greater bio-availability.

I have to limit raw veges because too much causes digestive issues,but I have some of both each day with the emphasis on cooked veges.
EngineerGuy replied to jc3737's response:
Hi jc,

You've found the perfect solution: raw and cooked. :-)

Quite right. Both raw and cooked have advantages, and best is lots of both.
