5 Foods That May Lower Your Risk For Stroke

Nutrition is important not only for the maintenance of your (desired) six pack abs, but regulated intake of “brain-rich” foods may help slow disease progression of various neurological disorders. Although stroke incidence in high-income countries fell by 42% between 1970 and 2008, overconsumption of calories, and increased prevalence of obesity, metabolic syndrome, and type II diabetes mellitus continue to threaten the decline. Although several risk factors are involved in the prediction of stroke occurrence, there is one factor that you can control—your diet. Here are 5 foods that may help lower your risk of stroke or stroke recurrence:

1. Tomatoes

Time to stock up on these round reds! Tomatoes are rich in lycopene, a potent antioxidant that protects against oxidative damage to the neurons during ischemic stroke. A recent study of 1,031 Finnish men reported that those in the highest quartile of serum lycopene concentrations had 59% and 55% lower risk of ischemic stroke and all stroke respectively, compared to men in the lowest quartile. The authors noted that the increase in lycopene concentrations may be due to increased amounts of tomato and tomato-based product intake after the men’s initial diagnosis of stroke.

2. Bananas

The next time you have a bowl of cereal for breakfast, add a few slices of this potassium rich fruit into the mix. A 2011 meta-analysis of eleven observational studies assessed the relationship between the level of habitual potassium intake and the incidence of cardiovascular disease. Analysis of 247,510 adults found that those with higher potassium intake (1.64 g/day) were associated with a 21% lower risk of stroke. Another meta-analysis reported that for every 1.0 g/day increase in potassium intake, the risk of stroke decreased by 11%.

3. Fish

If you love seafood, then you are in luck. Fish is an excellent source of protein and essential omega-3 fatty acids. A meta-analysis of 15 observations studies reported that eating three servings per week of fish was associated with a 6% lower risk of stroke. Some studies suggest that the consumption of oily fish (e.g. salmon, herring, trout, mackerel) drives the inverse relationship between fish intake and stroke risk, while others support the intake of lean fish (e.g. cod, haddock, sole).

4. Whole grains

This category of food consists of bran, germ, and endosperm from natural cereal. Seven observational studies have reported that increased whole grain intake (average of 2.5 servings/day vs. 0.2 servings/day) is associated with a trend of lower risk of incident stroke events and a significantly lower risk of cardiovascular disease events. It is important to note that these findings were not found with refined grain intake.

5. Chocolate

Who doesn’t enjoy a delectable piece of chocolate from time to time? A 2011 systemic review suggests that individuals with the highest level of chocolate consumption have 29% lower rate of stroke than those with the lowest levels of chocolate consumption. In keeping with these findings, a more recent 2012 publication prospectively following 37,103 men in the Cohort of Swedish Men report that moderate chocolate consumption may lower the risk of stroke. If these claims are valid, the mechanism of association may be due to the antihypertensive, anti-inflammatory, and antithrombotic effects of cocoa.
