Fruits or vegetables

As you know fruits and vegetables are at the pinnacle of the Healthiest Way of Eating.

That being said, Readers ask me whether fruits and vegetables are equally important. Here's what I tell them:We included a long list of both fruits and vegetables in the World's Healthiest Foods, and we did so not only for health and nourishment reasons, but also because of the beauty and diversity of these foods.

There are so many unique fruits and vegetables growing on the earth! The colors, shapes, and tastes of these foods are totally unique and unsurpassed within the food world! It's impossible for us to imagine the experience of the World's Healthiest Foods without ample amounts of fruits and vegetables.

When you compare fruits and vegetables on a nutritional basis, however, there is no question that vegetables are more nutrient dense and contain a much wider variety of nutrients than fruits.

If you think about the lives of the plants, this difference makes sense. In the world of vegetables, we eat many parts of the plants that either grow very close to the soil (like stems and stalks) or beneath the ground itself (like roots) This closeness to the soil brings the plant into contact with the diversity of soil minerals, and almost all vegetables are richer in minerals than fruits for this reason.

Fruits are also more of an end-stage occurrence: in the case of an apple tree, for example, the tree has already lived and developed for a good number of years before it produces a significant amount of edible fruit. Unlike a root, which is in charge of nutrient delivery from the soil up into the rest of the plant, the fruit (like an apple) is not nearly as active in supporting the life of the plant (although it's seeds are dramatically important in allowing the tree to produce new offspring and create future generations of apple trees).

Because the stems and stalks and roots are more involved in the plant's life support, they also tend to have a greater variety of vitamins (especially B complex vitamins) than fruits.Most fruits have a concentrated amount of sugar, and for this reason, are higher-calorie and less nutrient dense than most vegetables.

Starchy root vegetables like potatoes are closer to fruits in calorie content, but green leafy vegetables are enormously lower in calories and greater in nutrient density.

In summary, if you had to choose between fruits and vegetables as a foundation for your health, you would do best to select vegetables because of their greater nutrient diversity and nutrient density. Luckily, however, it is not an either-or situation, and you can take pleasure in the delights of both fruits and vegetables while increasing your reliance on the World's Healthiest Foods!

Do early intake of fish and fish oil protect against eczema and doctor-diagnosed asthma at 2 years of age?

Penelitian ini mencari hubungan antara konsumsi ikan dan n-3 PUFA terhadap pencegahan penyakit alergi (asma dan eczema) pada anak. Apakah sebaiknya cod liver oil dan ikan dikonsumsi selama kehamilan atau diberikan kepada bayi?
 
Hasil penelitian terhadap >3000 anak menunjukkan bahwa umur rerata konsumsi ikan adalah 9,1 bulan. Bayi yang makan ikan sekali seminggu atau lebih mempunyai risiko alergi yang lebih rendah yaitu adjusted OR (aOR) segala jenis ikan 0.62 (95% CI 0.42 to 0.91 p=0.02), untuk ikan berlemak aOR 0.21 (95% CI 0.05 to 0.86 p=0.03) dan untuk ikan tak berlemak aOR 0.67 (95% CI 0.41 to 1.08 p=0.10). Hubungan antara maternal diet dan penyakit alergi pada usia 2 tahun tidak signifikan.
 
Kesimpulan untuk mencegah penyakit alergi konsumsi ikan pada bayi lebih unggul dibanding konsumsi ibu selama kehamilan. Konsumsi ikan lebih unggul dibanding konsumsi n-3 PUFA.

Do early intake of fish and fish oil protect against eczema and doctor-diagnosed asthma at 2 years of age? A cohort study

  1. J Epidemiol Community Health 2010;64:124-129 doi:10.1136/jech.2008.084921

Abstract

Background There are ambiguous results regarding the role n-3 polyunsaturated fatty acids and fish might play in primary prevention of allergic diseases. The aim was to investigate the association between cod liver oil and fish consumption during pregnancy and in the first year of life and asthma and eczema at 2 years of age.

Methods From the Prevention of Allergy among Children in Trondheim study, a prospective birth cohort study in primary healthcare in Trondheim, Norway, 3086 children were followed prospectively from 1 year to approximately 2 years of age. The primary outcome variable was parental reported asthma and eczema at 2 years.

Results The mean age for introducing fish in the diet was 9.1 months. Excluding children with incident eczema before 1 year, a reduced risk of developing eczema was found if the child was eating fish once a week or more, adjusted OR (aOR) for any kind of fish 0.62 (95% CI 0.42 to 0.91 p=0.02), for oily fish aOR 0.21 (95% CI 0.05 to 0.86 p=0.03) and for lean fish aOR 0.67 (95% CI 0.41 to 1.08 p=0.10). The associations between maternal diet and eczema at 2 years and between the dietary factors and doctor-diagnosed asthma were all insignificant.

Conclusions Fish consumption in infancy was more important than maternal fish intake during pregnancy in preventing eczema in childhood. The intake of fish per se, not specifically n-3 polyunsaturated fatty acids, was most important in preventing eczema.
