I was looking up how sugar raises blood pressure worse than salt so I can send something to my mom who keeps trying to buy groceries loaded with sugar right in front of me (most of which have a first ingredient of sugar), while I cart her around to urgent care centers and cook extra for her so her blood pressure will get out of the critical range. Thought I would share what I found.
A study published in Open Heart by Drs. DiNicolantonio and Lucan explores which white crystal (sugar or salt) has the biggest impact on blood pressure levels. (DiNicolantonio JJ, Lucan SC.
Open Heart 2014;1:3000167)
Their findings show that:
Eating more sugar increases systolic blood pressure 6.9 mm Hg points and diastolic blood pressure 5.6 mm Hg in the short term, and 7.6/6.1 mm Hg if followed for more than 8 weeks.
- Drinking one 24-ounce soft drink can increase blood pressure by 15 systolic and 9 diastolic points and raise heart rate by 9 beats per minute.
- People who consume 25% more calories from sugar (which is easy to do) have a 300% increase in death rate due to cardiovascular disease.
- A high-fructose (sugar) diet for just 2 weeks increases blood pressure 7 mm Hg systolic and 5 diastolic, but also raises pulse rate, triglycerides, fasting insulin and is associated with fatty liver.
- The good news is there is no harm noted from eating more fruit, so don’t fret over having an apple, a peach, or a cup of berries. Do avoid fruit juice and dried fruit.
For the last 100,000 years, humans consumed not more than a few pounds of sugar per year, in the form of hard-earned honey, maple syrup, or sugar cane. It is only in the last few years that our intake has leaped to 100 to 150 pounds per year. Today, one in six people get 25% of all their calories from sugar, which is way too much! No wonder rates for diabetes and metabolic syndrome are skyrocketing at epidemic rates.
I think the data is crystal clear—we should spend more energy avoiding sugar. Sugar doesn’t just raise blood pressure levels. Eating more sugar and refined carbs (any grain processed into flour) will also:
- Worsen your cholesterol profile (makes your LDL and HDL sizes smaller) and lowers overall healthy HDL levels.
- Increase your risk for -
- Diabetes
- Heart disease and strokes
- Weight gain
- Memory loss
- Cancer
So we should be limiting our sugar intake to what I’d call an occasional treat, clearly not every day. When it is a special occasion, enjoy it.
