The influence of dietary fats on serum lipid levels in man
E. H. Ahrens, J. Hirsch, W. Insull, T. T. Tsaltas, R. Bloomstrand, M. L. Peterson

One of the most striking aspects of this seminal paper is the quality of the research presented, and the profound questions that are raised about the fundamental influence of the quantity and quality of dietary fats upon the serum lipid profile...



Prediction of serum cholesterol responses of man to changes in fats in the diet
A. Keys, J. T. Anderson, F. Grande

This paper is remarkable for several reasons. Firstly, it sets out to achieve what at first sight appears to be a near-impossible task, that is, to demonstrate a method for predicting serum cholesterol changes from the dietary source...



Quantitative effects of dietary fat on serum cholesterol in man
D. M. Hegsted, R. B. McGandy, M. L. Myers, E. J. Stare

Both similarities and striking differences are to be found between this paper and previous studies seeking to discover a mathematical prediction of the effect of dietary lipids upon serum cholesterol...



Serum cholesterol response to changes in the diet. IV. Particular saturated fatty acids in the diet
A. Keys, J. T. Anderson, F. Grande

Amidst the abundance of regression analyses and equation-solving that characterizes both this paper and the previous one from this group that is discussed in these summaries, there does appear to be at least one clear conclusion: dietary stearic acid does not have a serum cholesterol–raising effect...



The Seven Countries Study: 2289 deaths in 15 years
A. Keys, A. Menotti, C. Aravanis, H. Blackburn, B. S. Djordjevic, R. Buzina, A. S. Dontas, F. Fidanza, M. J. Karvonen, N. Kimura, et al

Epidemiological studies such as this rely on a long duration of follow-up (in this case 15 years) to obtain significant results, a period made all the more poignant in this case by the fact that two of the authors died before it reached publication...



Comparison of effects of dietary saturated, monounsaturated, and polyunsaturated fatty acids on plasma lipids and lipoproteins in man
F. H. Mattson, S. M. Grundy

This study was published at a time when questions were being raised about the long-term safety of polyunsaturated fats, and as a result carbohydrates were being recommended as a replacement for saturated fatty acids in the diet...



Comparison of monounsaturated fatty acids and carbohydrates for lowering plasma cholesterol
S. M. Grundy

Unlike previous studies focusing upon the comparison between polyunsaturated and saturated fats, this is one of the first studies to compare the impact upon plasma lipids of diets rich in carbohydrate (consequently low in fat) with those rich in monounsaturated fats...



Effect of dietary stearic acid on plasma cholesterol and lipoprotein levels
A. Bonamone, S. M. Grundy

An important question regarding the relative effects of different saturated fats upon the serum lipid profile is addressed in this study: do all saturated fats have a deleterious influence?)...



Effects of dietary trans fatty acids in high-density and low-density lipoprotein cholesterol levels in healthy subjects
R. P. Mensik, M. B. Katan

Prior to the publication of this paper, there were reports that drew conflicting conclusions about the influences of dietary fatty acids upon serum lipids...



Effects of a dietary portfolio of cholesterol-lowering foods vs lovastatin on serum lipids and C-reactive protein
D. J. Jenkins, C. W. Kendall, A. Marchie, D. A. Faulkner, J. M. Wong, R. de Souza, A. Eman, T. L. Parker, E. Vigden, K. G. Lapsley, et al

Jenkins et al investigate the intriguing hypothesis that dietary modification may have comparable benefits to a first generation statin (lovastatin) in altering low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and C-reactive protein (CRP) levels...
