In the 1970's the "low-fat/high carbohydrate is good" dogma was implemented to "help combat" obesity and heart disease. Dietary fat (especially saturated fat) was vilified as the enemy and the advice was to curtail its intake.
This advice (which is constantly repeated year after year for the past 40 to 50 years) has certainly been heeded as the figures below show. Carbohydrate consumption has risen sharply whilst fat consumption in the diet has declined.
Figure 1 shows the rise in carbohydrate consumption and the fall in fat consumption from 1971-2000 in the United States.
Figure 2 shows the rise in carbohydrate consumption (dots) and the prevalence of obesity (vertical bars).
What is the latest advice? Cut back even further on fats (especially saturated fat) - which of course means an even bigger proportion of your food will then be in the form of carbohydrates.
Why are we been told to cut back on saturated fats? People automatically think saturated fat is connected to heart disease. However is this really the case? Figure 3 shows the relationship between saturated fat consumption and heart disease.
