What is ALA in food?
α-Linolenic acid (ALA) is an n–3 (ω-3) fatty acid found mostly in plant foods such as flaxseed, walnuts, and vegetable oils, including canola and soybean oils. Most of the health benefits observed for n–3 fatty acids have been attributed to the marine-derived long-chain n–3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid, because of the strength of evidence from both epidemiologic studies and randomized controlled trials. Furthermore, the observed cardioprotective and other health effects of ALA have been credited to its precursor role in converting to EPA in the body. The promotion of fatty fish consumption for its documented health benefits may not be practical for those who are concerned with the unsustainability of marine sources or who avoid eating fish for a variety of reasons. ALA-rich plant sources are more abundant and may serve as a suitable alternate. It is therefore worthwhile to consider the evidence for the health benefits of ALA. The purpose of this review is to present the evidence from recent studies on the association between ALA and cardiovascular disease, type 2 diabetes, and fracture risk. The potential mechanisms that explain these associations will also be briefly discussed.
What does ALA stand for in medical terms?
1. ALA, α-linolenic acid ; CHD, coronary heart disease; CVD, cardiovascular disease; Q, quintile. Open in new tab. Clearly, there is a need for more prospective studies on ALA and CVD outcomes, but it is encouraging that, for at least total CVD outcomes, combining dietary and biomarker ALA suggests a modest protection.
What are the benefits of n-3 fatty acids?
There is convincing evidence from both epidemiologic and clinical trials that n–3 fatty acids reduce the incidence of CAD and all-cause mortality ( 4, 5 ). More than a decade ago, the American Heart Association issued a consensus statement ( 6) recommending the consumption of 2 servings of fatty fish/wk or 500 mg EPA and DHA/d for those without CAD and ~1 g/d for those with CAD. For the plant-derived α-linolenic acid (ALA), the suggestion was to include vegetable oils rich in ALA, but no specific amount was proposed. Most of the cardioprotective effects of n–3 fatty acids were attributed to the marine-derived EPA and DHA because of the strength of evidence from prospective cohort studies and randomized controlled trials (RCTs). As for ALA, the evidence is not conclusive, but there has been a steady increase in the number of studies supporting specific health benefits of ALA.
How to get ALA?
In the United States, it is also common to obtain ALA through various readily available salad dressings and oil spreads made from ALA-rich oils. In the body, ALA is converted through the desaturase and elongase enzymes to longer-chain n–3 fatty acids including EPA and DHA.
Does ALA protect against CVD?
In summary, it appears that ALA confers modest protection against CVD. Although the strength of the evidence is not nearly the same as for marine n–3 fatty acids, there is an increase in the number of studies in the past decade that support this protective association. There is still a lack of prospective studies focusing on CVD subtype to make firm conclusions on how ALA may modify the risk of these specific CVD outcomes. With regard to fracture risk and T2D, preliminary evidence suggests a protective role for ALA, but there is still a great need for more prospective studies and RCTs. Although there is some light shed on potential mechanisms of action by which ALA may lower the risk of CVD, fractures, and T2D, further elucidation of mechanisms requires both primary and secondary prevention RCTs. Until the strength of the evidence is increased in the future, specific recommendations for disease prevention cannot be made to the public. However, given that the sustainability of marine sources is a concern, and that ALA-rich plant sources are more abundant, ALA-rich plant foods may be recommended for inclusion in the diet, irrespective of the consumption of marine n–3 fatty acids, but specifically for those whose consumption of EPA and DHA from the diet is low. Particular attention should also be placed on the source of ALA. In the United States, some of the common sources of dietary ALA include vegetable oils, salad dressings, and oil-based margarines and spreads ( 10 ). Whole foods containing ALA, such as walnuts and flaxseed, provide other bioactive constituents that act synergistically with ALA to produce favorable modification of disease risk factors. It may be prudent to include such foods in the diet to provide ALA.
Does ALA help with T2D?
How ALA may confer a reduction in risk of T2D remains unclear. ALA may play a role in improving insulin sensitivity. In a cross-sectional study from Japan ( 48 ), dietary ALA was shown to be associated inversely with insulin resistance. In this cohort, those with the highest quartile of ALA intake (>1% of total energy) compared with the lowest quartile (<0.7% of total energy) had a 26% lower prevalence of insulin resistance among those with a BMI (in kg/m 2) of <25. The consumption of ~4 g ALA/d by eating flax-enriched bread for 10 wk ( 49) produced an 8.8% reduction in insulin resistance compared with the control wheat bread. Although fiber is known to improve insulin sensitivity ( 50 ), subjects in both interventions in this study consumed similar amounts of fiber, suggesting perhaps that ALA may have independent effects on insulin sensitivity. There is a need for large RCTs that look at ALA intervention and T2D incidence and risk factor outcomes to establish a causal relation and to elucidate potential mechanisms.
Where does ALA come from?
In Western diets, in addition to the typical sources of ALA (nuts, seeds, oils), a significant amount of ALA also comes from various readily available foods such as salad dressings and other oil-based margarines, which are difficult to fully capture by using a food-frequency questionnaire.
