“Bad” cholesterol fluctuations may worsen seniors’ brain health – AHA

•    Greater fluctuations in “bad” cholesterol levels may be linked to declining brain health in older adults.
    •    The negative effect from fluctuations was found regardless of average bad cholesterol levels or use of cholesterol-lowering drugs.

Greater fluctuations in “bad” cholesterol levels may be linked to worse cognitive function in elderly adults, according to new research in the American Heart Association’s journal Circulation.

In a study of European adults age 70 to 82 years old, researchers found that greater fluctuations in low-density lipoprotein cholesterol (LDL), or “bad” cholesterol, are associated with lower cognitive performance.

For example, study participants with the highest LDL cholesterol variability took 2.7 seconds longer on average to finish a cognitive test to name ink colors of color words written in different ink (for example, the word blue written in red ink), compared to individuals with the lowest variability.

“While this might seem like a small effect, it is significant at a population level,” said Roelof Smit, M.D., lead study author and a Ph.D. student at Leiden University Medical Center in Leiden, the Netherlands.

The link between variability and declining cognitive function was found regardless of average bad cholesterol levels or use of cholesterol-lowering statin drugs.

In addition, greater fluctuations in bad cholesterol were associated with lower brain blood flow and greater white matter hyperintensity load – which has been linked to endothelial dysfunction.

These results show LDL cholesterol variability may be important to neurocognitive function, Smit said.

“Our findings suggest for the first time that it’s not just the average level of your LDL-cholesterol that is related to brain health, but also how much your levels vary from one measurement to another,” Smit said. (my emphasis)

Measurements fluctuate because of diet, exercise, frequency of cholesterol-lowering statins and other factors, he said. However, these fluctuations might also reflect an increasingly impaired homeostasis; for example, due to age or underlying disease, added J.Wouter Jukema, M.D., Ph.D., senior author of the study and professor of Cardiology at the Leiden University Medical Center.

Green Ginger Grapefruit Smoothie – Guest Post Kelli Jennings

Regular readers know that I am a nearly daily bike rider here in Chicago. As such I read some cycling blogs, too. One of my faves is Loving the Bike.

And, one of that blog’s regular contributors is Kelli Jennings, an Expert Sports Nutritionist who writes Ask the Sports Nutritionist.

Kelli is not only a world class athlete, but also a first rate nutritionist who writes clearly and accurately about her subject.

She recently wrote an item Green Ginger Grapefruit Smoothie   that I thought would interest you.

I hate to be a downer, but I’ve got some bad news.  Grapefruits are tough to come by in the summer.  The prices go up and they’re not as plentiful.  I know, this likely ruined your Thursday.  I guess the only thing to do is eat ‘em up, while you can.

This week, we’ll review why grapefruits should be one of your go-to fruits and we’ll “wake it up” with a wonderfully refreshing grapefruit smoothie.  Grapefruits go above and beyond the nutrients of many foods, even other ones found in produce section.  Did I mention they can help you lose weight?  Bring on the grapefruits!

Recipe of the Week: Green Ginger Grapefruit Smoothie

Ingredients:
3/4 cup Greek yogurt or 1/2 scoop protein powder
1/2-1 pink grapefruit, peeled well
3/4 cup berries
1/4 avocado
1 cup spinach or other greens
1/2″ slice ginger
2 Tbsp chia seeds
1/2 cup water ice, if desired for consistency

Instructions:
Place all ingredients in the blender and process until smooth. Enjoy!

Nutrition information: Approximately: 385 calories, 44 gm carbs, 11 gm fiber, 15 gm protein.

Comments:

1) In the picture, this smoothie is obviously not green. I call it “green” because it includes a grapefruitsmoothie1-225x300whole cup of green. The berries’ color overtake the green. Either way, it’s not easy being green, and it’s all good stuff.

2) This is not Jamba Juice. If you want your smoothie to taste like Jamba Juice, you’ll have to go there and pay for a smoothie much higher in sugar and processed ingredients. If not, I think you’ll feel refreshed and satisfied having started your day with some ginger, greens, and grapefruit. I know I do!

Next, there’s lots of good reasons to eat grapefruits while you still can. On the list, is potential weight/fat loss. You’ve heard of the grapefruit diet, right? Eat grapefruits and lose weight. And of course, most cyclists wouldn’t mind losing fat and improving strength to weight ratio. But, is it science or quackery? Is there something magic to the grapefruit? Well, you can rest assured that I’m certainly NOT recommending you eat nothing but grapefruits. But, it may help to add them. Here’s some food for thought: Continue reading

What Do You Look for in a Cholesterol Report?

Regular readers know that I am a senior citizen and work at keeping up on my health. I get blood work done at least once a year and sometimes more often. This week was one of those times, so I thought it might help you to understand your cholesterol number more if I went over mine.

Here are my numbers from Tuesday.
CHOLESTEROL
197 Standard Range 0 – 200 mg/dL
TRIGLYCERIDES
46 Standard Range 50 – 150 mg/dL
HDL CHOLESTEROL
85 Standard Range >=40   mg/dL
LDL CHOL (CALC)
103 Standard Range 0 – 100 mg/dL
Non-HDL Cholesterol
112 Standard Range 0 – 130 mg/dL

As you can see from the standard ranges offered, I am on the high side for total cholesterol, but the main reason is that my HDL cholesterol – the good cholesterol – is so high.
