    This is the only video I found on all of youtube that specifically addresses how each micronutrient is determined

    It's funny how little videos out there that explains how nutritional labels information are found, so thanks for this!
    On top of that, this covers and summarizes a broad range of nutritional education and some common calorie question well!
    Although I hear the fat calories per day could be higher as long as overall calories is still at maintenance (just enough calories to maintain weight) and other macros are met.

    A very enjoyable explanation for what calories on nutrition labels mean. I would love to see a follow up about vitamins and minerals if possible. A lot of food is artificially enhanced with vitamins and minerals, but what about the food that naturally has those things?

    Although this is an older video, it is one of my favorites on food and nutrition. While it over-simplifies the causal nature of obesity to overeating, it still presents the data related to the process of converting food to energy via caloric method and is still the best video I have found. There are some newer facts which also are contributors to the obesity issues and health in general. Those are the introduction of ICE as a food item rather than simply a food preservative source of cooling and reducing molecular activity. Today, we gladly add a 'handful' [with all the added bacterial components still active on the hand] ice to a 'smoothie' loaded with fruits and/or vegetables and blended until liquid. Between the added cold and fluid to the digestive process, there is also the major data overload of getting all those food items in fluid form, thereby passing through the mouth with little or no chewing; the method which not only breaks the food particles down. This chewing is necessary for better absorption, of the nutrients within that luscious mouthful of smooth, cold, sweet, sour, salty, bitter, spicy flavors. Yet further infractions are bombarding our digestive process. This food is NOT getting the benefit of all the enzymes and digestive fluids in the mouth, excreted by the maxillary glands when chewing would have occurred by squirting into the food while still in the mouth. A first step in fixing this major issue is so simple it is almost criminal to not disclose; give up the use of ICE in your food intake.

    I would go as far to say the rise in obesity is more so the over consumption of CARBS which is sugar and refined sugars. There are unhealthy fats too, but it’s not healthy to do low fat diets.

    What truly gets people for weight gain is activity levels and Sugary Carbs smh. Most of those Carbs should come from Nuts, Oats, low intake of grains, and Fruits/veggies

    You might have had an answer already but weight loss comes from a Calorie deficit. If you do not consume enough Calories to maintain your body it will take the needed energy from fat stores in your body instead. So if you should be eating 2200 Calories a day and only eat 1800 you're losing weight no matter where those Calories are coming from.

    it'd be nice to see our "impulse" items change. I would like to see more fruit and veggies at the check out line than chips, soda, baked goods, energy drinks, candy...... just saying.

    And yet, science continues to prove some of the statements in this video are flat-out wrong, and always were. The details for how things were calculated was informative, but the nutritional assumptions presented are not accurate, and the statements made at the end are ill-informed.

    Perhaps because they were lacking omega 3 fats, and consuming trans fats and large amounts of sugar.

    5:46 Americans are fat because of a diet high in 'fats' and sugar.
    Americans are actually fat because of a diet high in carbs, specifically refined carbs, and sugar.
    The seeds for the current obesity epidemic were planted when the carb-heavy food pyramid was designed and promoted by US Health bodies. Companies started removing fat from foods and replaced it with sugar because food without fats tastes crap.

    "30 % of food intake should be fat"
    "One third of americans are obese"
    Heck i wonder if there's an correlation...

    • @goingfast522

      The recomendation looks fine to me, the problem is that the American diet is much higher.

    • @commercialcommunication9298
      @commercialcommunication9298 8 років тому +2

      The body needs fat! Fat supports our nerve function, cell membranes, cell, to help absorb fat-soluble vitamins A, D, K, E, for healthy skin and hair and the production of important hormones. The problem is when people intake too much total fat, or too many unhealthy fats such as saturated fat and trans fats. When they say "30% of food intake should be fat", they are also assuming a healthy intake level...so if a person is eating 9,000 kcal per day, thatd does not mean that 3,000 kcal from fat is recommended. The video probably should have said "30% of a person's recommended total calories should be derived from fat". Also, most textbooks give a range rather than just one number.

      @Cin9999 8 років тому

      its actually 1. "up to" 30% (by the WHO) 2. totally fine if the 30% are almost only omega 3

    • @Cin9999
      @Cin9999 8 років тому

      its also a joke that they say 2000kcals a day xD
      i eat more in every of my 3 meals

      Calories needed depends on many factors. There are complex formulas. A person's level of activity is obviously relevant. If you are eating over 2,000 kcal per meal (6,000+ kcal/day) then you must be doing some very serious exercising, to there is some other issue involved.
