SFAs raise levels of low-density lipoprotein (LDL) cholesterol, which is strongly linked to heart disease. The American Heart Association (AHA) recommends that individuals obtain \u0026lt;7% of their energy from SFAs [AHA Nutrition Committee et al. \u003Cem\u003ECirculation\u003C\/em\u003E 2006]. In the United States, recent data indicate a small reduction in the percentage of calories consumed from SFAs as well as decreases in total serum cholesterol. However, the latter is attributed to an increase in the use of cholesterol-lowering medications rather than dietary changes [Ford ES, Capewell S. \u003Cem\u003EPloS One\u003C\/em\u003E 2013].\u003C\/p\u003E\u003Cp id=\u0022p-6\u0022\u003ELDL cholesterol is comprised of subclasses of particles with differing cholesterol content and CVD risk. SFAs appear to affect large LDL particles, which are less strongly associated with CVD. Carbohydrates have a major influence on smaller LDL particles, which have greater entry into the arterial wall and are subjected to faster oxidation. Moderate carbohydrate restriction can improve atherogenic dyslipidemia [Krauss RM et al. \u003Cem\u003EAm J Clin Nutr\u003C\/em\u003E 2006].\u003C\/p\u003E\u003Cp id=\u0022p-7\u0022\u003EEpidemiologic evidence to date shows no reduction in heart disease when SFAs are replaced by carbohydrates, and there is some evidence that the risk may be increased. However, the type of carbohydrate may be important. In one study, replacing SFAs with carbohydrates with low-glycemic index values was associated with a lower risk of myocardial infarction (MI; HR, 0.88; 95% CI, 0.72 to 1.07), whereas replacing SFAs with carbohydrates with high glycemic index values was associated with a higher risk of MI (HR, 1.33; 95% CI, 1.08 to 1.64; \u003Ca id=\u0022xref-fig-2-1\u0022 class=\u0022xref-fig\u0022 href=\u0022#F2\u0022\u003EFigure 2\u003C\/a\u003E) [Jakobsen MU et al. \u003Cem\u003EAm J Clin Nutr\u003C\/em\u003E 2010].\u003C\/p\u003E\u003Cdiv id=\u0022F2\u0022 class=\u0022fig pos-float  odd\u0022\u003E\u003Cdiv class=\u0022highwire-figure\u0022\u003E\u003Cdiv class=\u0022fig-inline-img-wrapper\u0022\u003E\u003Cdiv class=\u0022fig-inline-img\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/21\/8\/F2.large.jpg?width=800\u0026amp;height=600\u0026amp;carousel=1\u0022 title=\u0022Risk of Heart Attack Increases as High Glycemic Index Carbohydrates Are Substituted for SFAs\u0022 class=\u0022fragment-images colorbox-load\u0022 rel=\u0022gallery-fragment-images-357576156\u0022 data-figure-caption=\u0022Risk of Heart Attack Increases as High Glycemic Index Carbohydrates Are Substituted for SFAs\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003E\u003Cimg class=\u0022fragment-image\u0022 alt=\u0022Figure 2.\u0022 src=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/21\/8\/F2.medium.gif\u0022\/\u003E\u003C\/a\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cul class=\u0022highwire-figure-links inline\u0022\u003E\u003Cli class=\u00220 first\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/21\/8\/F2.large.jpg?download=true\u0022 class=\u0022highwire-figure-link highwire-figure-link-download\u0022 title=\u0022Download Figure 2.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload figure\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00221\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/13\/21\/8\/F2.large.jpg\u0022 class=\u0022highwire-figure-link highwire-figure-link-newtab\u0022 target=\u0022_blank\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EOpen in new tab\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00222 last\u0022\u003E\u003Ca href=\u0022\/highwire\/powerpoint\/13428\u0022 class=\u0022highwire-figure-link highwire-figure-link-ppt\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload powerpoint\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv class=\u0022fig-caption attrib\u0022\u003E\u003Cspan class=\u0022fig-label\u0022\u003EFigure 2.\u003C\/span\u003E \n            \u003Cp id=\u0022p-8\u0022 class=\u0022first-child\u0022\u003ERisk of Heart Attack Increases as High Glycemic Index Carbohydrates Are Substituted for SFAs\u003C\/p\u003E\n         \u003Cq class=\u0022attrib\u0022 id=\u0022attrib-2\u0022\u003EReproduced from Jacobsen MU et al.

Although challenged in a more recent meta-analysis [Ramsden CE et al. \u003Cem\u003EBMJ\u003C\/em\u003E 2013], other evidence is strong that the risk of coronary heart disease is reduced when SFAs are replaced with PUFAs [Astrup A et al. \u003Cem\u003EAm J Clin Nutr\u003C\/em\u003E 2011].\u003C\/p\u003E\u003Cp id=\u0022p-10\u0022\u003ELow fat diets in general appear to be healthier. Among persons at high CV risk, a Mediterranean diet (fruits, vegetables, fish, and whole grains) supplemented with extra-virgin olive oil or nuts reduced the incidence of major CV events [Estruch R et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013].\u003C\/p\u003E\u003Cp id=\u0022p-11\u0022\u003EAlthough studies of specific eating patterns such as the Dietary Approaches to Stop Hypertension (DASH) eating plan and the Mediterranean diet have shown CVD benefits, the actual beneficial element in the diet has not been conclusively identified. The evidence to date shows no clear benefit of substituting carbohydrates for SFAs although there might be a benefit if the carbohydrate is unrefined and has a low glycemic index [Astrup A et al. \u003Cem\u003EAm J Clin Nutr\u003C\/em\u003E 2011]. The Women\u0027s Health Initiative trial, which assessed diets with reduced total fat intake and increased intakes of vegetables, fruits, and grains, showed no reduction of heart disease risk or stroke [Howard BV et al. \u003Cem\u003EJAMA\u003C\/em\u003E 2006]. A meta-analysis of 21 prospective cohort trials supported these findings [Siri-Tarino PW et al. \u003Cem\u003EAm J Clin Nutr\u003C\/em\u003E 2010].\u003C\/p\u003E\u003Cp id=\u0022p-12\u0022\u003EIt may be that the intake of red meat is responsible for much of the risk of heart disease (and diabetes) attributed to saturated fat. Red meat consumption has been associated with an increased risk of CVD and cancer mortality, while substitution of other healthy protein sources is associated with lower mortality risk [Pan A et al. \u003Cem\u003EArch Intern Med\u003C\/em\u003E 2012]. Elevated trimethylamine-N-oxide (a proatherosclerotic metabolite) levels, found in red meat predict an increased risk of major adverse CV events [Tang WH et al. \u003Cem\u003EN Engl J Med\u003C\/em\u003E 2013].\u003C\/p\u003E\u003Cp id=\u0022p-13\u0022\u003EThus, it is not just the presence of cholesterol and saturated fat in the diet that matters; it is also the foods that are the sources of those factors. Individual SFAs may have different CV effects and major SFA food sources contain other constituents that could influence CVD risk. The combination of multiple biomarkers and the use of clinical endpoints could help substantiate the effects on CVD. In general, fatty fish, nuts, other polyphenol-rich foods, and legumes are good dietary choices, while trans-fats, sugars, and glycemic starches are not [Astrup A et al. \u003Cem\u003EAm J Clin Nutr\u003C\/em\u003E 2011].\u003C\/p\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2014 MD Conference Express\u00ae\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/13\/21\/8.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_figures.js?nzl5hq\u0022\u003E\u003C\/script\u003E\n\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzl5hq\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
