Cholesterol may affect brain functions – Study

Having lost three family members to Alzheimer’s Disease and dementia, I was fascinated by this information from researchers in Berlin.

A study led by researchers at the Hospital del Mar Medical Research Institute (IMIM) and the Institute of Medical Physics and Biophysics at the Faculty of Medicine in Charité Hospital, Berlin, published in the journal Nature Communications, demonstrates that the cholesterol present in cell membranes can interfere with the function of an important brain membrane protein, through a previously unknown mode of interaction. Specifically, cholesterol is capable of regulating the activity of the adenosine receptor, by invading it and accessing the active site. This will allow new ways of interacting with these proteins to be devised that in the future could lead to drugs for treating diseases like Alzheimer’s.

2-brain

The adenosine receptor belongs to the GPCR family (G Protein-Coupled Receptors), a large group of proteins located in cell membranes, which are key in the transmission of signals and communication between cells. GPCRs are therefore involved in the majority of important physiological processes, including the interpretation of sensory stimuli such as vision, smell, and taste, the regulation of the immune and inflammatory system, and behavior modulation.

Dairy – Good or Bad? – MNT

I started drinking soymilk some years ago after reading some scare stories about cow milk consumption. I don’t even remember the reasons now, but I do look forward to my quarts of soymilk that I buy from Costco. Since starting I can’t put my finger on any negative health effects.

This extensive Medical News Today rundown by Hannah Nichols gives a lot of useful detail on the subject.

What do government health guidelines say? According to the United States Department of Agriculture (USDA) food MyPlate guidelines, to get all the nutrients you need from your diet, healthy food and beverage choices should be made from all five food groups, including fruits, vegetables, grains, protein foods, and dairy.

The dairy food group consists of all fluid milk products and many foods that are made from milk. The USDA recommend that food choices from the dairy group should retain their calcium content and be low-fat or fat-free. Fat in milk, yogurt, and cheese that is not low-fat or fat-free will count toward your limit of calories from saturated fats.

What happens after you quit smoking: A timeline

As regular readers know, I feel strongly that smoking is an unmitigated blight on our lives. We lose over 170,000 people to it every year – just in lung cancer alone – totally preventable. To be honest, I am surprised that anyone who can read would choose to be a smoker. Nonetheless, it is so. I have a Page on it – How many ways does smoking harm you?   which I recommend you check out after reading this.

I am reproducing what follows from Medical News Today because I like the way they spell out positive aspects of ceasing smoking. Jenna Fletcher wrote it.

2c7122334e35ae6793d84daae31c44ee

Cigarette smoking is one of the leading causes of preventable death in the United States. Despite this, some smokers find quitting daunting. They think it will take a very long time before seeing improvements in their health and well-being.

However, the timeline for seeing real benefits to quitting smoking is much faster than most people realize. Health benefits begin in as little as an hour after the last cigarette and continue to improve. Continue reading

Nuts Improve Cholesterol Levels – Tufts

“Nuts to you” used to be a way of putting someone down. But, according to Tufts, nuts might be a good way to get some of those pesky cholesterol levels down.

nuts.jpg

At least part of the proven cardiovascular benefits of eating nuts can be explained by their effects on cholesterol and other blood lipids, according to new Tufts research. The meta-analysis of 61 controlled intervention trials totaling 2,532 participants found that tree nut intake lowered total cholesterol, LDL cholesterol, triglycerides and lipoproteins (particles that transport fats through the body). The major determinant of cholesterol lowering appeared to be nut dose rather than nut type, so you can eat your favorite nuts without worrying about nutrient differences.

“This meta-analysis provides the most comprehensive estimates to date of the effects of tree nut intake on major cardiovascular disease risk factors,” says Dariush Mozaffarian, MD, DrPH, dean of Tufts’ Friedman School and editor-in-chief of the Health & Nutrition Letter, who was a co-author on the study.

Lead author Liana C. Del Gobbo, PhD, adds, “Accumulating evidence indicates that nut intake lowers risk of cardiovascular disease events. Our findings showing that nut intake significantly improves the lipid profile provide critical mechanistic evidence to support a causal link between nut intake and lowered cardiovascular disease risk.” Continue reading

Harvard on the health aspects of eggs

Don’t feel bad for harboring any confusion about just how healthy or unhealthy eggs are in your diet. There has been a lot of information and, it turns out, some misinformation about the little chicken nuggets over the years. So, to put it eggs-actly straight here is the latest from the Harvard T.H. Chan School of Public Health.

Long-vilified for their high cholesterol content by well-meaning doctors and scientists researching heart disease, eggs now seem to be making a bit of a comeback. So what changed?

32BB1B6300000578-0-image-a-5_1459499829576.jpg

While it’s true that just one egg yolk has 200 mg of cholesterol—making it one of the richest sources of dietary cholesterol—eggs also contain additional nutrients that may help lower the risk for heart disease. In addition, the moderate amount of fat in an egg, about 5 grams, is mostly monounsaturated and polyunsaturated fat. It’s also crucial to distinguish between dietary cholesterol and cholesterol in the blood, which are only weakly related. The focus on dietary cholesterol alone was de-emphasized as more attention was placed on the influence of saturated and trans fat on blood cholesterol. Accordingly, the Dietary Guidelines for Americans 2015 removed the prior recommendation to limit consumption of dietary cholesterol to 300 mg per day.

4 Ways to eat your way to lower cholesterol – Harvard

Following is one of those helpful email I get from Harvard from time to time. I thought you might find it interesting.

Many people can reduce cholesterol levels simply by changing what they eat. For example, if you are a fan of cheeseburgers, eating less meat (and leaner cuts) and more vegetables, fruits, and whole grains can lower your total cholesterol by 25% or more. Cutting back on saturated fat (found in meat and dairy products) and trans fat (partially hydrogenated oils) can reduce cholesterol by 5% to 10%.

8440448

Here are four steps for using your diet to lower your cholesterol.

Stick with unsaturated fats and avoid saturated and trans fats. Most vegetable fats (oils) are made up of unsaturated fats that are healthy for your heart. Foods that contain healthy fats include oily fish, nuts, seeds, and some vegetables. At the same time, limit your intake of foods high in saturated fat, which is found in many meat and dairy products, and stay away from trans fats. These include any foods made with “partially hydrogenated vegetable oils.”

Get more soluble fiber. Eat more soluble fiber, such as that found in oatmeal and fruits. This type of fiber can lower blood cholesterol levels when eaten as part of a healthy-fat diet. Continue reading

High cholesterol intake and eggs do not increase risk of memory disorders

I am now and  have been for years a big fan of eggs. A hundred years ago, it seems, I worked on the Chicago Mercantile Exchange trading floor where I covered the egg futures market along with pork bellies, live cattle and live hog futures. In that capacity, I learned a great deal about eggs from their production to our consumption. I have posted on them numerous times. Here are a few: Eating eggs is good for you. I wrote that in the first month of this blog’s existence. Feel free to type e-g-g-s in the search box at the right to read more posts on eggs.

eggs-04

A new study from the University of Eastern Finland shows that a relatively high intake of dietary cholesterol, or eating one egg every day, is not associated with an elevated risk of dementia or Alzheimer’s disease. Furthermore, no association was found in persons carrying the APOE4 gene variant that affects cholesterol metabolism and increases the risk of memory disorders. APOE4 is common in Finland. The findings were published in the American Journal of Clinical Nutrition. Continue reading

1. Exercise controls weight
Exercise can help prevent excess weight gain or help maintain weight loss. When you engage in physical activity, you burn calories. The more intense the activity, the more calories you burn.
Regular trips to the gym are great, but don’t worry if you can’t find a large chunk of time to exercise every day. To reap the benefits of exercise, just get more active throughout your day — take the stairs instead of the elevator or rev up your household chores. Consistency is key. Continue reading

On flu shots and blood work

Last Thursday, I posted Tips on fighting the flu. I thought it was a good time for these tips as we are entering flu season. Also, I had an appointment to get my own flu shot on the following day. Please check out that post as there is a lot of good information in it for you relevant to protecting yourself from the flu bugs eating away at your system. Also, Dr. Jonathan, who writes the blog All About Healthy Choices had some very informed ideas on fighting the flu which he offered in comments.

Flu-Season.jpg

I know that there is a division of opinion about getting flu shots. I think flu shots, like politics, religion and labor unions are third rail conversational topics. Some people swear by flu shots (me) and some swear at them. The decision is yours, of course.  I would offer anecdotally that I started getting them around 16 years ago when I was teaching journalism at Northwestern University. One of my students interviewed a senior citizen who said that she had been getting flu shots for 10 years and in that time she had not only not caught the flu, but she didn’t even catch a cold. That was good enough for me. I have been getting them ever since with similar results. Continue reading

More Bad News about Inadequate Sleep

I created the Page – How Important is a good night’s sleep? more than three years ago after taking a course on sleep. My opening sentence is  “Sleep is one of the under-appreciated aspects of our daily lives.” Arianna Huffington’s book The Sleep Revolution is one of Amazon’s bestsellers.

Valuable-Sleep.jpg

Now comes the University of Helsinki reporting on the damage too little sleep does to the
blood vessels.

Getting too little sleep causes changes in the metabolism of cholesterol, demonstrates a study conducted at the University of Helsinki. According to the results, long-term sleep loss may contribute to the development of cardiovascular disease.

Lack of sleep has previously been found to impact the activation of the immune system, inflammation, carbohydrate metabolism and the hormones that regulate appetite. Now University of Helsinki researchers have found that sleep loss also influences cholesterol metabolism. Continue reading

10 Reasons to Include Buckwheat In Your Diet Plans

I am as new to buckwheat as you are. I always thought it was the stuff they put into airplane neck pillows. This post shows how wrong I can be.

Tony

Buckwheat for your health

bowl of buckwheat seeds

  1. Buckwheat is high in fiber; good for those with constipation.
  2. The protein in buckwheat has all 9 essential amino acids (that the body cannot manufacture), making it closer to being a “complete” protein.
  3. Buckwheat is high in the amino acid lysine, which is used for tissue growth and repair.
  4. Buckwheat is gluten-free so this makes it suitable for those with wheat allergies.
  5. Buckwheat is rich in calcium, iron, vitamin E, and B vitamins, magnesium, manganese, zinc and copper.
  6. The magnesium in buckwheat, helps relaxes blood vessels; helps improve circulation, decrease blood pressure and reduce cholesterol.
  7. Buckwheat helps to stabilize blood sugar levels. Due to the slower breakdown and absorption of the carbohydrates in buckwheat, this helps to raise our blood sugar levels more evenly. This especially good for those suffering with diabetes by helping to control their blood sugar levels.
  8. Buckwheat is low in calories

Do I Have to go on Statin Drugs for the Rest of my Life to Fight High Cholesterol?

I am reblogging this analysis I wrote two years ago. At the time I thought it was good useful information for the general public. Now, It seems my doctor says that it applies to me.

I have just had my annual flu shot and pneumonia booster. In the course of my annual check up, I also had my blood work done.

As regular readers know I am 75  years old and in the best health of my entire life. I weigh around 155 pounds and have a resting heart rate below 50 beats per minute.

Here are my Cholesterol numbers:
CHOLESTEROL 182
Optimal (not to be construed as a target for drug therapy): <170 mg/dL
TRIGLYCERIDE 41
Optimal (not to be construed as a target for drug therapy): <100 mg/dL
Highly Abnormal (please review with your medical team further): >499 mg/dL

HDL CHOLESTEROL 77
Optimal (not to be construed as a target for drug therapy): >50 mg/dL
LDL CHOL (CALC)  97
Optimal (not to be construed as a target for drug therapy): < 100 mg/dL
Highly Abnormal (please review with your medical team further): >189 mg/dL

Non-HDL Cholesterol 105
Optimal (not to be construed as a target for drug therapy): <120 mg/dL
Highly Abnormal (please review with your medical team further): >219 mg/dL

Despite my excellent physical condition and these good test results, my doctor recommended that I go on a statin drug, atorvastatin, to reduce my risk of heart attack or stroke.

POSTED OCT 9, 2015 To clarify:

My Doctor sent me the following:

… although your cholesterol numbers are quite good your overall risk for stroke and heart attacks is still quite high. I calculated your risk of having a stroke or heart attack in the next 10 years and it is 21.6%. I did this with the new American Heart Association Guidelines (AHA) and it is based on your age,sex, race, blood pressure, smoking status and hypertension as well as diabetes. We recommend starting cholesterol medications if the risk is above 7.5%. Even though you are doing everything right your overall risk is still high, as is the risk for most 75 year old males. Many physicians would recommend that your begin a cholesterol medication so I would have your consider taking atorvastatin.

For the record, I declined the recommendation saying that I felt more comfortable relying on my positive lifestyle.

Here is what I wrote back: Thanks very much for your prompt turnaround of my blood work. I also appreciate your considered recommendation regarding taking a statin prescription. At this time I am not comfortable with that. I understand the statistics, but I think those statistics include a lot of men who are not as healthy or health-conscious as I am. I think I would like to continue on with my current lifestyle of daily exercise and healthy eating and avoid the drugs. If I find a deterioration in my condition in the future, I will revisit this decision.

One Regular Guy Writing about Food, Exercise and Living Past 100

“Millions more Americans could end up taking cholesterol-lowering statin drugs under new recommendations released Tuesday that advocate a dramatic shift in the way doctors assess and treat cardiovascular risk,” according to the Washington Post.

“Roughly a quarter of Americans age 45 and older already take statins, which include familiar brands such as Lipitor and Zocor, to treat high cholesterol. But that number could grow sharply under far-reaching guidelines detailed by the American Heart Association and the American College of Cardiology.”

The leading cause of death for Americans is heart disease. About one in every four deaths in the United States, or about 600,000 annually, are attributed to heart disease, according to the Centers for Disease Control and Prevention.

Is Your Cholesterol in Good Shape?

The message that hasn’t changed is this: If your blood has a lower level of bad cholesterol (low-density lipoprotein, or LDL) and a higher level of the good kind (high-density lipoprotein, or HDL), you will reduce your risk of heart disease. Lifestyle modifications and/or medications are usually effective in shifting your cholesterol levels into a healthy range.

Cooking with Kathy Man

Gilles Beaudin wrote . . . .

Cholesterol has been getting a lot of press lately. The most recent news is the about face on dietary cholesterol. The American dietary guidelines no longer encourage restricted cholesterol consumption. Strong scientific evidence shows that dietary intake has little influence on levels of good and bad cholesterol in the body.
