As well as income-related variations, the role of fish innutrition shows marked continental, regional and national differences. Inindustrialized countries, where diets generally contain a more diversified rangeof animal proteins, a rise in per capita provision from 19.7 kg to 27.7 kg seemsto have occurred. This represents a growth rate close to 1% per year. In thisgroup of countries, fish contributed an increasing share of total protein intakeuntil 1989 (accounting for between 6.5% and 8.5%), but since then its importancehas gradually declined and, in 1997, its percentage contribution was back to thelevel prevailing in the mid-1980s. In the early 1960s, per capita fish supply inlow-income food-deficit countries was, on average, only 30% of that of therichest countries. This gap has been gradually reduced, such that in 1997,average fish consumption in these countries was 70% of that of the more affluenteconomies. Despite the relatively low consumption by weight in low-incomefood-deficit countries, the contribution of fish to total animal protein intakeis considerable (nearly 20%). Over the past four decades, however, the share offish proteins in animal proteins has declined slightly, because of faster growthin the consumption of other animal products.

In the last 20 years, we have increased sugar consumption in the U.S

The total food fish supply and hence consumption has beengrowing at a rate of 3.6% per year since 1961, while the world’s populationhas been expanding at 1.8% per year. The proteins derived from fish, crustaceansand molluscs account for between 13.8% and 16.5% of the animal protein intake ofthe human population. The average apparent per capita consumption increased fromabout 9 kg per year in the early 1960s to 16 kg in 1997. The per capitaavailability of fish and fishery products has therefore nearly doubled in 40years, outpacing population growth.

The impact that agriculturalpolicies, particularly subsidies, have on the structure of production,processing and marketing systems - and ultimately on the availability of foodsthat support healthy food consumption patterns - should not beoverlooked.

Enzymes in vegetables are inactivated by the blanching process. Blanching is the exposure of the vegetables to boiling water or steam for a brief period of time. The vegetable must then be rapidly cooled in ice water to prevent it from cooking. Contrary to statements in some publications on home freezing, in most cases blanching is absolutely essential for producing quality frozen vegetables. Blanching also helps to destroy microorganisms on the surface of the vegetable and to make some vegetables, such as broccoli and spinach, more compact.
