Probiotics are live bacteria in yogurt, other dairy products and pills. And while probiotics have been shown effective in managing certain gastrointestinal conditions, they do not have the same power that prebiotics do. First, they’re delicate — heat and stomach acid can kill them, rendering them ineffective before they’ve even been digested.
New Study: Probiotics May Improve Blood Pressure
The new study, a systematic review and meat analysis of nine randomized, controlled studies (considered to be the “gold standard” in research), found significant benefits among people with high blood pressure who consumed probiotics in products like yogurt and milk.
It appeared that at least 100 billion colony-forming units of probiotics a day was necessary to trigger such improvements, and the benefit was only seen in those who consumed probiotics for eight weeks or more. According to the researchers:
“The present meta-analysis suggests that consuming probiotics may improve BP by a modest degree, with a potentially greater effect when baseline BP is elevated, multiple species of probiotics are consumed, the duration of intervention is ≥8 weeks, or daily consumption dose is ≥1011 [100 billion] colony-forming units.”
Cause of High Blood Pressure
Blood pressure is the measure of the force of blood pushing against blood vessel walls. The heart pumps blood into the arteries (blood vessels), which carry the blood throughout the body. High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood to the body and contributes to hardening of the arteries, or atherosclerosis, and to the development of heart failure.
8 Simple Steps to Help Normalize Your Blood Pressure
I’ve recently compiled my full list of strategies to prevent hypertension. However, below you’ll find some of the highlights. In most cases, this is a condition that can be managed and oftentimes reversed with natural lifestyle changes, including not only optimizing your gut flora but also the tips that follow:
- Skip breakfast: Research shows that intermittent fasting helps fight obesity and type 2 diabetes, both of which are risk factors for high blood pressure. Your body is most sensitive to insulin and leptin after a period of fasting. While there are many types of fasting regimens, one of the easiest to comply with is an eating schedule where you limit your eating to a specific, narrow window of time each day. I typically recommend starting out by skipping breakfast, and making lunch your first meal of the day.
- Optimize your vitamin D levels: Arterial stiffness (atherosclerosis) is a driving factor for high blood pressure. As your blood travels from your heart, cells in the wall of your aorta, called baroreceptors, sense the pressure load, and signal your nervous system to either raise or lower the pressure. However, the stiffer your arteries are, the more insensitive your baroreceptors become, and the less efficient they become at sending the appropriate signals. Vitamin D deficiency is, in turn, linked to stiff arteries, which is why optimizing your levels is so important.
- Address your stress: The link between stress and hypertension is well documented. Suppressed negative emotions such as fear, anger, and sadness can severely limit your ability to cope with the unavoidable every day stresses of life. It's not the stressful events themselves that are harmful, but your lack of ability to cope. I recommend the Emotional Freedom Technique (EFT) to transform your suppressed, negative emotions, and relieve stress.
- Normalize your omega 6:3 ratio: Most Americans get too much omega-6 in their diet and far too little omega-3. Consuming omega-3 fats will help re-sensitize your insulin receptors if you suffer from insulin resistance. Omega-6 fats are found in corn, soy, canola, safflower, and sunflower oil. If you're consuming a lot of these oils, you'll want to avoid or limit them. For omega-3s, your best bet is to find a safe source of fish, or if this proves too difficult or expensive, supplement with a high-quality krill oil, which has been found to be 48 times more potent than fish oil.
- Eliminate caffeine: The connection between coffee consumption and high blood pressure is not well understood, but there is ample evidence to indicate that if you have hypertension, coffee and other caffeinated drinks and foods can exacerbate your condition.
- Vitamins C and E: Studies indicate that vitamins C and E may be helpful in lowering blood pressure. If you're eating a whole food diet, you should be getting sufficient amounts of these nutrients through your diet alone. If you decide you need a supplement, make sure to take a natural (not synthetic) form of vitamin E. You can tell what you're buying by carefully reading the label. Natural vitamin E is always listed as the “d-” form (d-alpha-tocopherol, d-beta-tocopherol, etc.) Synthetic vitamin E is listed as “dl-” forms.
- Olive leaf extract: In one 2008 study, supplementing with 1,000 mg of olive leaf extract daily over eight weeks caused a significant dip in both blood pressure and LDL (“bad”) cholesterol in people with borderline hypertension. If you want to incorporate olive leaves as a natural adjunct to a nutritionally sound diet, look for fresh leaf liquid extracts for maximum synergistic potency. You can also prepare your own olive leaf tea by placing a large teaspoon of dried olive leaves in a tea ball or herb sack. Place it in about two quarts of boiling water and let it steep for three to 10 minutes. The tea should be a medium amber color when done.
- Quick tricks: Increasing nitric oxide in your blood can open constricted blood vessels and lower your blood pressure. Methods for increasing the compound include taking a warm bath, breathing in and out through one nostril (close off the other nostril and your mouth), and eating bitter melon, rich in amino acids and vitamin C.
Prebiotics share the same goal with probiotics, which is to keep the colon healthy. However, prebiotics act indirectly. They are indigestible substances that come from various foods and serve as sources of nourishment for the probiotics. In other words, they are food for the good microorganisms.
