A recent large, long term, 5 continent study in the Lancet shows that eating 3-4 servings of fruits, vegetables or legumes every day is associated with a 22% lower risk of death from any cause. Eating more then 3-4 servings of fruits/vegetables/legumes every day did not show any association with risk of death. Raw vegetable intake was strongly associated with a lower risk of death, whereas cooked vegetable intake showed less impact on risk of death. A higher level of texture in food is related to increased neuro-regeneration, which is an agreement with the findings of this study regarding raw vegetables.
A second report of the same population in the same issue of the Lancet reported on fat and carbohydrate intake.
- High carbohydrate intake was associated with higher risk of death from all causes
- Total fat and individual types of fat were associated with a lower risk of death for all causes.
- Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease deaths”.
- A higher intake of saturated fat was associated with a lower risk of stroke but no other outcomes
The relationship between carbohydrates and risk of death was true for Asian countries who traditionally consume a higher proportion of carbohydrates. There was no relationship between protein intake and mortality.
The relationship between hip-waist circumference, cognitive functioning, physical activity and family history of premature death were not included in these two studies.
This is an important study because it has been done recently, it includes 18 countries in 5 continents and included 135,335 individuals aged 35 to 70 years without cardiovascular disease. Participants were enrolled into the study between Jan 1, 2003, and March 31, 2013. For the current analysis, they included all outcomes events to March 31, 2017. The oldest subjects would be 74 at the end of the study. There was a median 7.4 years (5·5–9·3) of follow-up. The study results included an analysis of income, education, economic status of the country and urban rural location and the results were the not affected by these factors
Practical implications for your daily food plan
Using the optimum percentage of carbohydrates and fat from the Lancet study the following table shows the distribution of macronutrients in three different scenarios.
|Ideal||1500 cal||2000 cal||2500 cal|
|Carbohydrates||45%||174 gm||230 gm||288 gm|
|Protein||19%||71 gm||95 gm||119 gm|
|Fat||35%||58 gm||78 gm||97gm|
I investigated some on-line diet and nutrition website to find out if their food plans come close to the ratios above. Very few of the sites posted the fat/protein/carbohydrates of their diet plans and those that did, did not come close to these ratios except for the food plans posted by the American Diabetes Association. Their site has multiple food plans with the total fat/protein/carbohydrate for the day as well as recipes.
Here is how two of their meal plans compare to the ideal ratios reported in the Lancet study. These two sample meal plans are a bit lower in fat than the optimum ratios reported in the Lancet study. However, the ADA was the only site that I found that reported macronutrients as well as recipes for their food plans. So it appears the meal planning done for diabetics fits right into the ratios reported in the Lancet study and so could be a universal model for everyone.
