Lower Cholesterol – If HDL is high do you worry about an elevated LDL level?

Here’s another question I asked Dr. Cynthia Shelby-Lane and her answer.

Lisa Nelson RD: If you have a patient with a high HDL level, let’s say an HDL greater than 80; are you concerned if their LDL level is elevated??

Dr. Shelby-Lane: New research has revealed that LDL or “bad” cholesterol inhibits the breakdown of fat in adipocytes, or fat cells, thus suggesting that it is a regulator of fat stores.

This new knowledge gives you three important areas to work on to not only boost your HDL number but to also boost your HDL quality. It is interesting indeed that HDL-building nutrients like niacin and pantethine also help lower triglycerides and improve cardiovascular health, giving more proof to this new field of emerging HDL science.

Key nutrients that support HDL are:

  • Niacin: Niacin has been shown to directly boost your levels of apoA-I while lowering triglycerides. I recommend non-flushing inositol hexanicotinate.
  • Pantethine: Pantethine provides the energy to help form HDL, while also providing energy to assist triglyceride and LDL cholesterol metabolism.
  • Phosphatidyl Serine: This nutrient contains a mix of the key phospholipids that are often lacking in the diet and are needed to construct the healthy cell membrane of HDL.

Along with HDL-building nutrients it is vital to take anti-inflammatory nutrients to calm down immune cells that are inducing free radical damage to the apoA-I protein. The basis of this approach is a diet rich in fruits and vegetables. Many nutrients may be of assistance. Some top choices include grape seed extract, resveratrol, tocotrienols (vitamin E), vitamin C, DHA, pomegranate, and blueberries. Stress management and getting adequate sleep are essential.

Ensure your fasting blood sugar never gets above 90. If it is, use “anti-glycating” nutrients that help protect your HDL from sugar-induced damage. Top choices include R-alpha lipoic acid, grape seed extracts, and resveratrol.

HDL cholesterol is a pivotal molecule that protects your circulation and directly manages its health. It is no longer adequate to simply have an HDL score above 40. You need high quality HDL – HDL that is energized and ready for duty.

Lisa Nelson RD: So, if you have an individual with an HDL of 88, do you take action if their LDL level is elevated at 145? Or are you less concerned, due to the protective effects of the high HDL level?

Dr. Shelby-Lane: This requires further testing with an expanded lipid profile to determine risk and treatment options. (See my answer to question number 7 to learn more about the expanded lipid profile test.)

How to Lower Cholesterol in 8 Simple Steps

Lower Cholesterol – Do you need to treat a low HDL level?

Here’s another question I asked Dr. Cynthia Shelby-Lane and her answer.

Lisa Nelson RD: Should individuals with low HDL levels receive treatment even if all other levels are normal?

Dr. Shelby-Lane: According to ScienceDaily (May 29, 2005) — High circulating levels of the “good cholesterol” HDL are associated with decreased risk of cardiovascular disease. HDL helps the liver excrete extra cholesterol by binding to a receptor in the liver called scavenger receptor-BI (SR-BI). However, the signaling events between HDL and SR-BI that afforded heart healthy benefits were not known.

In a study appearing online on March 24, 2005, in advance of the April 1, 2005 print edition of the Journal of Clinical Investigation, Philip Shaul and colleagues from the University of Texas Southwestern Medical Center examine the following pathway:

The authors show that HDL activates an enzyme called eNOS and sets off a cellular signal that depends on cholesterol efflux and two intact domains of SR-BI — the transmembrane domain and its cytoplasmic tail. These regions of SR-BI may serve as “cholesterol sensors” which set into motion cellular events to activate eNOS. This may be the mechanism responsible for the ability of HDL to reduce cardiovascular disease risk.

Lisa Nelson RD: Again, let’s clarify. If an individual has low HDL levels they should seek treatment even if all other cholesterol levels are normal. Correct? Correct?

Dr. Shelby-Lane: Again, a low HDL is an isolated risk factor and should be included in the overall health picture, and can be modified with diet, nutrition, and some newer drugs.

Heart Health – Is fish oil safe?

vitamine

Fish oil supplements are a great alternative for people that do not eat fish often to boost their omega 3 intake and promote heart health.

There’s been some media speculation about possible contaminants, such as mercury, within fish oil supplements. However, good news if you supplement fish oil, there are minimal contaminants within the supplements!

There have been several studies, specifically a report by ConsumerLab.com and Harvard Medical School, finding no mercury or PCBs within over 40 popular fish oil supplements. Fish oil is typically taken from fish, such as cod and sardines, that do not contain high levels of mercury. Also, many manufacturers distill the fish oil to remove contaminants.

Lower Cholesterol – Top Omega 3 Sources to Lower Cholesterol

If you have been following along, you know from the article "Get a Grip on Fatty Acids" that the right ratio of omega 6 to omega 3 fatty acids promotes a lower cholesterol. 
 
The goal is not to cut omega 6 fatty acids (such as corn oil, beef, and chicken) completely from the diet, but to achieve a ratio of 4:1 or 1:1 omega 6 to omega 3.  In order to attain this ratio you need to increase your omega 3 intake. 

Your options for doing this:
 
1. Eat fish at least twice a week.

If you like fish, this would be my first choice.  Fish contains DHA.  Research is starting to indicate health benefits, such as lower cholesterol, lower triglycerides, and higher HDL (good) cholesterol, linked to DHA alone.  Be aware of mercury content of fish, especially if you are pregnant. 

2. Take a fish oil supplement.

Start with the smallest bottle you can find and make sure you do not have the unpleasant side effect of burping with a fishy aftertaste.  Not everyone has this problem, so you may be fine.   To decrease likelihood of this problem I recommend taking the supplement and then eating.  That way something is "on top" of the fish oil.  Fish oil has a tendency to go rancid, so keep supplement refrigerated, especially if you buy a bottle of 250 or more.

3. Flaxseed.

You can buy flaxseed two different ways – whole seed or ground.  In order for the body to utilize the omega-3 fatty acids, flaxseed must be ground.  If the flaxseed is not ground it passes straight through the body without being absorbed.  Flaxseed is high in fiber, so by ingesting whole flaxseed you have increased your fiber intake, which is beneficial, but if you grind your flaxseed you will have the added benefit of increasing your omega-3 fatty acid intake and lowering cholesterol. 

4. Flaxseed oil supplement.

Provides the omega 3 fatty acid ALA in a simple supplement.  Now, ALA is not as effective as DHA and EPA at lowering cholesterol, but still results in an improved ratio of omega 3 to omega 6.  Again, may go rancid so refrigerate.

5. Add omega 3 nut and seed sources to your daily intake.

Especially walnuts, pumpkin seeds, Brazil nuts, and sesame seeds.  Nuts are high calorie, so watch your intake.  If you gain weight, you are not doing your heart any favors!

High Blood Pressure and Magnesium

magnesiumMagnesium is not a mineral that tops discussions very often; however, magnesium is critical to over 300 bodily functions.  Magnesium maintains normal muscle and nerve function, helps regulate blood sugar levels, promotes normal blood pressure and heart rhythm, maintains bone strength, and supports a healthy immune system.

Many people consume a diet low in magnesium receiving less than two-thirds of the recommended dietary allowance. Good magnesium sources include whole grains, spinach, broccoli, squash, beans, popcorn, nuts, pork, and seeds. Fair sources of magnesium include dairy products, chocolate, and meats.

A magnesium deficiency takes a long time to develop. Magnesium deficiency symptoms include irregular heartbeat, weakness, fatigue, numbness, muscle pain, disorientation, and seizures. Conditions related to increased risk for magnesium deficiency include alcoholism, poorly controlled diabetes, intestinal disorders (Crohn’s disease), and intake of certain medications (diuretics). Sup-optimal levels of magnesium intake have been linked with diabetes, hypertension, osteoporosis, and pregnancy discomfort.

When someone has type II diabetes they are making adequate insulin levels. The problem with type II diabetes is that the cells do not recognize the insulin. When cells do not recognize insulin they do not let sugar from the blood enter the cell and blood sugar levels remain elevated. This leads to sugar spilling over into the urine, organ damage, and other complications. Magnesium is a factor in this because it’s the “key” that opens the door for insulin to get into the cell.  If magnesium levels are low there are no keys to open the door and insulin is unable to do its job resulting in continued high blood sugar levels.  When diabetes is poorly controlled the loss of magnesium in the urine is even greater.

Blood levels of potassium, calcium, and magnesium are closely connected and all influence blood pressure. Studies have linked low magnesium levels with elevated blood pressure. As an aside, if you have ever been told to eat a banana by your doctor, you should also increase your magnesium intake. FYI – Bananas are not the best source of potassium – potatoes are!

Magnesium is a major component of the matrix (middle) of bones. Low magnesium levels cause fragile bones that are less flexible and have a slower recovery rate if injured.

Adequate levels of magnesium are related to decreased leg cramps during pregnancy. A magnesium deficiency is also a risk factor for gestational diabetes.

Recommended Dietary Allowances (RDA) for Magnesium:

Men 350 mg per day
Women 280 mg
Pregnancy 300 mg
Lactation 355 mg first 6 months; 340 mg next 6 months

You do NOT want to take megadoses of magnesium – more is not better in this case.  You just want enough to meet the RDA. If you feel your intake of magnesium from foods is low, taking a basic multivitamin is a simple way to ensure you meet your needs. Read the multivitamin label carefully because not all multivitamins include magnesium. Always check with your doctor before altering your medications or supplements.

Magnesium may not be an exciting mineral, but it is critical.  Ensure you are eating adequate sources of magnesium rich foods and/or consider a supplement to promote optimum health.

Heart Health – The Link Between Wine and Omega 3's

A new study out of Europe is showing a link between wine consumption and increased omega 3 content in blood plasma. The study found that one glass of wine for women and two glasses per day for men leads to an increased use of the omega 3 fatty acids found in fish. It’s suggested that it’s not the alcohol responsible for this boost of omega 3’s, but other wine components (i.e. polyphenol antioxidants). The same increase in omega 3’s was not seen when beer or other spirits were consumed with fish.

So, if you enjoy a glass of wine combining your wine with a heart healthy fish based meal it looks like you’ll reap greater heart health rewards.
