Three things everybody agrees about nutrition


Credit: www.eatforhealth.gov.au

What should you eat?

The answer is confused by any number of factors, including:

● people who regard their food preferences as nutritional imperitives

● people who (often unconsciously) regard food as entertainment, a cure for boredom or stress, or a solution to any number of psychological symptoms, & ignore nutrition

● propaganda from marketing organisations for food industries — beef, sugar, salt etc.

● charlatans who want to part you from your money with large volumes of cheap fat, sugar & salt, fad diets, or devices such as blenders

However, there are three things almost all authorities agree on:
1. Minimise sugar
2. Avoid artificial trans fats
3. Eat more vegetables

If you read the comments in the article below, keep in mind:

● Ignore most of the fruit vs vegetables debate. A botanist will tell you that a fruit is the part of a flower in which the seeds develop1. Thus, a wheat grain & a tomato are fruits & an apple is a false (or accessory) fruit2 (to a botanist, the fruit of an apple is the fibrous part around the seeds that you probably throw away — the core). For a discussion of nutrition, the botanist’s definition is irrelevant. This is much more useful: “From a culinary standpoint, vegetables are less sweet — or more savory — & served as part of the main dish. Fruits are more sweet & tart & are most often served as a dessert or snack.”3 So vegetables include what the botanist will call a fruit (tomato), stem (celery), leaf (lettuce), flower (broccoli), root (carrot) & tuber (potato), but exclude grains, nuts & seeds.

● If a “diet” differs from the advice given above & in the article linked below, it is generally the “diet” which is wrong. Keep in mind that many popular diets were originally designed to treat specific medical conditions & may even be dangerous if used for other purposes.
