Midlife Weight Loss Reduces Heart Disease Risk
You are at greater risk of heart disease if you were overweight as a teen, compared to those who gained weight later in life. However, it was never clarified if this was because overweight teens become overweight adults OR does being overweight during your teen years cause irreversible damage.
Good news has come out of recent research published in The Archives of Internal Medicine that indicates losing weight mid-life can reduce heart disease risk if you’ve been overweight since your teens.
This research was conducted by Harvard Medial School reviewing data on 19,000 Harvard alumni who entered their freshman year of school between 1916 and 1950. Follow up on these individuals occurred over 82 years and evaluated at habits, heart disease, body mass indexes.
Study results found the heaviest students were most likely to become overweight adults. Obese freshmen men had almost double the risk of dying from heart disease later in life compared to those of normal weight during their college years. Freshmen men who were overweight their freshmen year also had a substantially increased risk of dying from a heart disease.
The good news came when researchers factored in middle age and any change in weight at that time. Men who began college overweight or obese, but lost weight and were considered normal weight in middle age no longer had an increased risk of dying from heart disease.
7 Tips to Lower Cholesterol & Still Enjoy Thanksgiving
The holidays are here again, so let’s review some tips so you stick with your diet to lower cholesterol levels AND still enjoy a satisfying Thanksgiving meal.
Tip #1: Pass the Gravy
Traditional gravy is a high fat source. To make your gravy a little healthy, use a spoon to remove fat from meat and poultry dishes prior to mixing up your gravy. Another option to remove the fat is to freeze the pan drippings and then remove them before making gravy. Next, don’t go overboard. Add a little gravy for flavoring and pass it on.
Tip #2: Trim the Turkey
Limit your turkey to about 4 ounces. This would be right around the size or a deck of cards. Select white turkey meat without the skin to cut back on unnecessary fat calories.
Tip #3: Stuff the stuffing right
Boost your veggie intake by sautéing a lot of veggies into your stuffing. Some veggies may include finely diced celery, carrots, and onions.
Cholesterol and the Gene Apolipoprotein E
Are you someone that has followed a heart healthy diet “to the letter” and still struggled to lower blood pressure or cholesterol levels? If so, it’s possible the diet didn’t work for you due to your specific genetic makeup.
Mapping of the human genome (13 year project that identified all genes in human DNA) was completed by scientists in 2003.
For the most part, genes are the same between individuals, with just a 1% variation. This small difference is what accounts for our unique physical attributes, biological processes, and metabolism. It’s also this slight difference that makes one individual more susceptible to heart disease than another.
Nutrigenomics
This has opened the door for nutrigenomics and the role it can play disease prevention. You see, dietary recommendations, such as Dietary Reference Intakes and Recommended Dietary Allowances, are established to meet the needs of 99% of the population from a statistical perspective. However, a “one size fits all approach” doesn’t necessarily work. Now, don’t get me wrong, it’s a great foundation to base your diet around, but if you have a specific disease or increased risk for disease, this is where nutrigenomics can step in.
Nutrigenomics looks at the interaction between nutrients and genes, because how we respond and metabolize nutrients is influenced by our genes.
Apolipoprotein E
The Apolipoprotein E (APOE) genotype influences coronary heart disease risk. APOE was discovered back in 1970 and can bind to triglyceride rich lipoproteins and acts as a binding mechanism for receptors.
Clogged Arteries: Young Doesn't Equal Healthy
Shouldn’t you be the “picture of health” as a young adult? Guess it shouldn’t come as a surprise that looks are deceiving.
Canadian researchers presented study results recently at the 2011 Canadian Cardiovascular Congress regarding their study of 168 adults between the ages of 18 and 35 years-old.
Study participants had no family history of heart disease, nor any other known risk factors, such as diabetes, obesity, high blood pressure, high cholesterol, or smoking.
Guess what? Researchers found a “staggering” number of participants to have atherosclerosis, which is a build-up of plaque along artery walls. Almost half of participants had signs of atherosclerosis – 48%.
Height, weight, body mass index (BMI), and waist circumference were recorded for all participants. MRI scans measured both subcutaneous (fat under the skin) and visceral fat (fat around vital organs).
These measurements found many participants to have greater waist circumferences and higher levels of visceral fat within the chest and abdomen. These high levels of visceral fat increase risk of suffering a heart attack or stroke at some point in their lives. It’s this high level of visceral fat that is likely contributing to the early signs of atherosclerosis.
These Canadian findings corroborate previous research that has found up to 80% of young American’s killed in war or car accidents to have premature and hidden atherosclerosis.
What Can You Do?
Does Vitamin D Deficiency Increase Cardiovascular Risk?
Vitamin D deficiency is fairly common. Vitamin D is not actually a vitamin, but a hormone the body produces from sunlight.
According to a review of existing research there is evidence low vitamin D levels impact cardiovascular disease risk, specifically blood pressure, insulin resistance, and coronary artery disease. The review of around 75 mostly observational studies was published in the Journal of the American College of Cardiology.
Whether or not taking supplemental vitamin D will reduce cardiovascular risks or how much is needed to be effective is still to be determined. We now need more randomized control research studies to examine the impact of high dose Vitamin D supplementation to weigh the pros against the cons.

Prevent Heart Failure with Lifestyle Changes
The way you choose to live, impacts your risk for disease. A new study published in the September issue of Circulation: Heart Failure has found that not smoking, losing weight, being active, and eating a diet high in vegetables may decrease your risk for heart failure.
Heart failure is the condition where the heart becomes weakened and does not pump blood and oxygen throughout your system effectively.
Researchers followed over 18,000 men and close to 20,000 women in Finland. Participants ranged in age from 25 to 74 years-old and were followed for about 14 years. During this 14 year time period, 445 women and 638 men developed heart failure.
Smoking and Excess Weight Increase Heart Failure Risk
Researchers concluded that men who smoked were at an 86 percent increased risk of heart failure compared to non-smokers. For women the risk increased 109 percent for smokers.
