It’s important to pace yourself properly when exercising. If you’re just starting a program, aim at the lowest part of your target zone (50 percent) during the first few weeks. Gradually build up to the higher part of your target zone (85 percent). After six months or more of regular exercise, you may be able to exercise comfortably at up to 85 percent of your maximum heart rate. However, you don’t have to exercise that hard to stay in shape.
Flax seed is rich in omega-3 fatty acids, and has been shown in some studies to lower blood pressure. A recent review suggested taking 30–50 grams of whole or ground seeds per day for more than 12 weeks to get the best benefits. Flax seed may protect against atherosclerotic cardiovascular disease by reducing serum cholesterol, improving glucose tolerance, and acting as an antioxidant.
Start by eating nuts. Pistachio nuts, singled out among other nuts, seem to have the strongest effect on reducing blood pressure in adults. This is according to a recent review and scientific analysis of 21 clinical trials, all carried out between 1958 and 2013. The review appears online in The American Journal of Clinical Nutrition, a publication of the American Society for Nutrition.
Consider once again the analogy of the garden hose. If you turn on the water “harder,” there is more pressure in the hose. Excessive salt in the diet can result in excessive fluid volume in the blood, which results in elevated blood pressure. This cause, too, is reversible, as a plant-based diet of whole, natural foods, devoid of added salt, is naturally low in sodium chloride.
Omega-3 fats are typically found in flaxseed oil, walnut oil and fish, with fish being by far the best source. Unfortunately, most fresh fish today contains dangerously high levels of mercury. Your best bet is to find a safe source of fish, or if this proves too difficult, supplement with a high quality krill oil, which has been found to be 48 times more potent than fish oil.
