Do You Have High Blood Pressure? Find Out with This New Online Interactive Tool

Do You Have High Blood Pressure? Find Out with This New Online Interactive Tool

Nearly half of the adults in the U.S. have high blood pressure. This means that you or someone close to you has a blood pressure reading at 130/80 or higher.

It wasn’t always this way – just a couple of years ago 1 in 3 Americans had high blood pressure instead of nearly 1 in 2.

So why the change? Does this mean we’re getting less healthy?

It’s quite the opposite. Based on years of scientific study, the change means we’re actually more aware of the effects of elevated blood pressure.

Two years ago, the definition of high blood pressure changed from 140/90 to 130/80 (technically 130+ or 80+, but we’re keeping it simple here). The result is that more people became classified as having high blood pressure. It doesn’t mean that thousands of people became ill overnight, though. It means we want people to know that high blood pressure is serious, and that it can begin damaging your blood vessels and organs at lower levels than previously thought, particularly if you don’t act to keep your numbers from rising.

It’s worth noting that blood pressure tends to rise naturally as we age, so it typically hasn’t been on the health radar for people under age 45. However, with the new definition, an important health alert was sent to people in their 20s and 30s to pay attention to their blood pressure levels. Among men aged 20 -44, the rate of high blood pressure nearly tripled. Among women in that age range, it doubled.

The American Heart Association has created an interactive tool that can help you not only identify your health risk according to your blood pressure level, but also provide notes on what actions you can take to ensure it stays at, or gets to, a healthy level. You can check it out at www.heart.org/BPlevels.

Making changes that matter can have a significant impact on your blood pressure levels. In fact, most of those who suddenly find themselves with high blood pressure under the new definition will be given a “prescription” for lifestyle changes – not medicine – that can lower their pressure.  Even for those who do require medication to control their levels, lifestyle changes help those meds work better and can even help you stay on lower doses. Some examples of a lifestyle change prescription include:

Physical activity:

  • 90 – 150 minutes per week of aerobic activity can drop your top blood pressure number (called systolic pressure) by 5-8 mmHg.
  • 90 – 150 minutes per week of dynamic resistance exercise can drop your systolic blood pressure 4 mmHg

 A healthy diet:

  • Eating a diet rich in fruits and vegetables, whole grains, and low-fat dairy, such as the DASH eating plan can drop your systolic pressure up to 11 mmHg.

 Sodium (i.e. salt):

  • Reducing your salt intake by about 1000 mg per day has a similar effect on systolic pressure as increasing aerobic activity – dropping it about 5 mmHg.

 Weight loss:

  • For about every 2 pounds lost, your systolic pressure could drop 1 mmHg.

The benefits of lifestyle change can add up quickly. Many of the same lifestyle prescriptions that lower blood pressure also reduce the risk of other dangerous conditions such as diabetes, high cholesterol, and heart disease. Eating a healthy diet, maintaining a healthy weight, and getting regular physical activity can help you lead a healthier and longer life!

Understanding Portion Control Better

Understanding Portion Control Better

Question:

Please help me better understand portion control. How much is too much versus too little? Is there a chart to help explain the differences between men and women? Does age and weight matter? Are there ways to make portion controlling easier?

Answer:

Controlling portions is a way to manage volume of food served and thus consumed. There is no specific way that is the best, just as there is no perfect serving for all people of any one particular food. A standard portion is a means to compare the nutritional content of different foods, e.g. “a half-cup of ice cream versus a half-cup of popcorn…”

The approach I recommend is a combination of a) the American Institute for Cancer Research’s “New American Plate” which has a greater proportion of plant foods than a typical diet and b) serving sizes adjusted for energy needs as suggested by MyPlatePlan. The key is to know your total caloric requirement first! This takes into account gender, age and weight.

Here are some common portion sizes provided in terms of measure with a corresponding way to “eyeball” the relative portion size in order to help you identify what portions look like. You can also practice by using your scale to weight various foods and then attribute a way to gauge that portion size by using objects such as your hands and fingers. See the examples below.

Bread, Cereal, Rice and Pasta (commonly 1-3 per meal)

  • 4” pancake or waffle = serving size 1   pancake = width just covers palm of adult hand
  • Bread = serving size 1 slice (1 oz.) = standard sandwich slice of bread
  • Pasta, rice, cooked cereal = serving size ½ Cup = size of a custard cup or ½ baseball

Vegetables (goal: 2-3 per meal)

  • Chopped vegetables (raw non-leafy) = serving size ½ Cup = size of a custard cup or ½ baseball
  • Raw leafy vegetables = serving size 1 Cup = 1 baseball or fist of an average adult

Meat and Protein (commonly 1-3 per meal)

  • Nuts = serving size 1/3 Cup = level palmful for average adult
  • Lean meat, poultry, seafood = serving size 1 oz. = size of adult thumb
  • Peanut butter = serving size 2 Tablespoons = size of a ping-pong ball
  • Beans, cooked = serving size ¾ Cup = size of a tennis ball

Fats and Oils (limit to 1 per meal)

  • Butter, margarine or oil = serving size 1 teaspoon = 1 pat or size of a half-dollar
  • Cream cheese = serving size 1 oz. = size of two dominoes
  • Mayonnaise or dressing = serving size 1 Tablespoon = top portion of adult thumb
  • Sour cream or reduced = serving size 2 Tablespoons = size of a ping-pong ball
  • calorie salad dressing

Fruit (commonly 2-3 per day)

  • Dried fruit = ¼ Cup = 1 golf ball
  • Canned, chopped or cooked = serving size ½ Cup = size of a custard cup or ½ baseball
  • Fresh fruit = serving size 1 medium or ½ large = 1 tennis ball or ½ softball
  • Berries or grapes = serving size 1 Cup = 1 baseball or fist of an average adult

Milk, Cheese and Dairy products (commonly 1-3 per day)

  • Natural hard cheese = serving size 1½ oz. = 9-volt battery or 1-inch cube
  • Cottage cheese = serving size ½ Cup = size of a custard cup or ½ baseball

These 7 Foods Help Promote Brain Health

These 7 Foods Help Promote Brain Health

It takes more than regular walks and the daily crossword to keep your brain in top cognitive shape! What you eat plays a larger role in mental fitness and preventing age-related decline in brain function. Like the rest of your body, the brain needs to be properly nourished from the start for optimum performance. An overall healthy diet is great, in addition there are certain types of food that promote brain health. Here’s a rundown of these brain preservers: 

1. Fish 

Oily fish like wild salmon, albacore tuna and sardines provide docosahexaenoic acid (DHA), a type of omega-3 essential for brain development and function, helping neurons trigger and cells regenerate. Long-term intake of adequate DHA has been linked to improved memory and learning ability. People who regularly eat fish are less likely than their peers to have depression. In fact, the American Psychiatric Association has endorsed the fatty acids in fish as an effective part of depression treatment.1  

You can’t start too early! The FDA and EPA agree eating fish is especially important for pregnant or nursing women because it helps with the growth and development of children’s brains and even helps boost IQ.  

Vegans can get their omega-3s from flaxseed, walnuts, chia seeds, algae-like seaweed or supplements.

2. Leafy greens  

Green leafy vegetables like spinach, kale, and collard greens provide vitamin K, folate, beta carotene, and lutein – nutrients that may support brain function and cognitive health.2 Eat at least one-half cup serving of leafy greens daily to get enough of these neuroprotective compounds. 

3. High antioxidant foods  

Powerful oxidation fighters that protect the brain3 are found in vegetables (broccoli, leafy greens), fruits (berries), nuts and the spice curcumin. Antioxidants’ positive effects on neural function are the reason why such foods are encouraged for younger people to slow age-related memory decline and prevent Alzheimer’s disease.  

4. Heart-healthy diet 

A cardiovascular protective diet is an important factor in battling age-related declines in brain function. Cerebrovascular disease, Alzheimer’s disease, and dementia are linked by the circulatory system; vascular cognitive impairment and vascular dementia stem from damage to the vessels leading to the brain. 

Good nutrition in younger people is associated with better blood flow and increased brain size, thus protecting the brain from age-related volume decrease. Also, maintaining a healthy weight may preserve gray matter from dementia-related decline.4  

5. Potassium-rich foods 

Because they counteract the effects of sodium on fluid balance, potassium-rich foods are important to combat hypertension, a well-documented risk factor for dementia. Potassium-rich foods include potatoes, tomatoes, bananas, coconut water, avocado and winter squash. 

The National Academy of Sciences even assigned “managing blood pressure for people with hypertension” as one of the three classes of interventions to prevent cognitive decline.5 And the MIND diet (a combination of DASH “Dietary Approaches to Stop Hypertension” with a Mediterranean diet) is associated with preservation of stroke survivors’ brain function. 

6. Mediterranean diet 

Following a Mediterranean diet might improve cognitive function in seniors and delay the onset of Alzheimer’s disease by a few years.6,7,8 A Mediterranean diet is characterized by high intake of vegetables, legumes, fruits, cereals, fish and unsaturated fatty acids (mostly as olive oil), low intake of saturated fatty acids, meat and poultry, low/moderate intake of dairy products and a regular but moderate amount of alcohol (mostly wine drank at meals). 

7. Coffee 

Coffee consumption is correlated with a reduced risk of developing Alzheimer’s disease and Parkinson’s disease.9 This neuroprotective benefit is independent of caffeine but may be related to the roasting process due to one of coffee’s polyphenolic compounds.10  

The Takeaway 

Whether you choose fish, potassium-rich fruits and vegetables, coffee or an array of heart-healthy powerhouse foods it’s possible to boost brain power, function, and mental wellness while forestalling degenerative brain disease through diet. Nutrition is often the best medicine – now that’s food for thought!

What’s the Deal Between Flaxseed and Fertility?

What’s the Deal Between Flaxseed and Fertility?

Question:

Does flaxseed help in increasing fertility and weight loss?

– Shamily BM

Answer:

There has been a lot of chatter in the media regarding flaxseeds and fertility. Looking at the research, I found evidence to support its effect on menstrual cycle and hot flashes, but nothing conclusive regarding conception in humans. So, flaxseed may have an insignificant effect.

Flaxseeds are high in fiber which helps promote satiety so that appetite is dampened and fewer calories are consumed. Theoretically, this would translate into weight loss if people didn’t compensate elsewhere in their diets. Again, there’s a lack of studies showing an isolated effect on body weight from flaxseed consumption alone.

No matter the physiological effect, it would take a lot of flaxseed to make an apparent isolated difference. My advice is that cracked or crushed flaxseeds* should be included to complement an overall healthy diet, similar to the addition of chia seeds, garlic, or ginger. Start with a teaspoon here and there to see in which foods it’s most acceptable. I like it on yogurt, in smoothies, oatmeal, grain breads, mustard, soups, and meatballs. If you’re committed you can work up to 2-4 tablespoons of flaxseed a day, as recommended by health experts.

*Why cracked or crushed flaxseed is best – Whole flaxseed is a good source of soluble fiber and lignans (phytoestrogen precursor) but isn’t fully digested to get the full nutritional benefit. Freshly cracked or crushed flaxseeds offer fiber and lignans plus thiamin, magnesium, and omega-3 fatty acids including alpha-linolenic acid. Ground flaxseed, milled flaxseed, and flax meal can also be used but spoil more readily than the whole flaxseed, so keep them in the freezer. Flaxseed oil doesn’t contain the fiber, lignans or micronutrients; it only has the fat.

How to Determine Your Macro Breakdown

How to Determine Your Macro Breakdown

Question:

I would like to know how I determine what my macro breakdown should be? How do I know how to calculate my split as far as protein/fats/carbs based on my weight & height? And what carbs are good for me? Female, Weight 170 lbs., Height 5’2’, Weightlift 5 days per week Cardio 3-5 times per week. I need help (guidance) with the nutrition part of my weight loss journey.

– Yolanda G.

Answer:

Given your current exercise regimen, your estimated daily energy needs for weight loss are about 2,000 calories if 20-30 years old (subtract 75 calories per decade older). Not knowing anything about your present intake, I’d recommend a rough caloric distribution of 30% fat, 20% protein, and 50% carbohydrates. Breaking down the 2,000 calories would give us 67 gm fat, 100 gm protein and 250 gm carbohydrate per day.

I’m so glad you asked about which carbohydrates are good! That indicates you’re aware that quality matters as much as quantity – for all three macronutrients. Complex carbohydrates that are more wholesome (less refined) are preferred over processed sources. Think of oats, quinoa, corn, potatoes, and vegetables complimented by simple carbohydrates from fresh fruit and milk products.

Here’s a one-day sample 2,000 calorie menu providing 27% fat, 22% protein, and 51% carbs*:

  • Breakfast – 1 Cup bran cereal, 1 Cup 1% milk, 1/2 grapefruit, and 1 large egg
  • Lunch – 3 oz. tuna, 1 Tbsp. mayonnaise, 4 rye crisp crackers, large dark green salad, ½ C. chickpeas, 2 Tbsp. of oil-based or ‘green goddess’ dressing
  • Dinner – 4 oz. skinless chicken breast, 1 Cup of broccoli, ½ Cup of corn

3 Snacks –

  • 1 large apple with 2 Tbsp. of peanut butter
  • 1 carrot + 1 celery with ¼ Cup of hummus
  • 6 oz Greek-style plain yogurt with 1 Cup berries

* Calculated by Registered Dietitian Nutritionist using Fitday.com’s food log function. Findings were used along with RDN’s professional judgment.
