With all the obesity and eating disorders going on, it seems like maybe we’re not educated about nutrition and exercise enough to eat healthy .I know for a fact that they didn’t teach us squat about nutrition or weight loss in public school, which is in my opinion a major concern.
But we already have good, healthy food that you can grow in your backyard : fruit and veggies 🙂
Thanks, I didn’t know about Michelle Obama!! That is an awesome thing she is doing.
I think it’s the FDA’s and parents’ fault, really. They try to get schools to serve healthier lunches (which, by many standards, are still not very healthy.) Additionally, excessive attention is paid to Calories, while very little is paid to what TYPE of Calories are being consumed (i.e. protein, carbohydrates, fats).
The harm of fat is also grossly overestimated, and importance of avoiding simple carbs hardly mentioned at all (most people don’t know that sugars are simple carbs, let alone that many of their favorite non-sugary foods also contain simple carbs).
I asked my school why we can’t be served whole milk, considering that fat-free milk contains as much as 10 more grams (roughly 2.5 teaspoons) more sugar than whole milk. They said that they have no control over what they feed us.
The other day, we had a school-wide (girls and boys separated) assembly (I’m a senior in high school), where we were handed a tiny flyer telling us how to “eat healthily.” It involved a number of moronic comments, including living a low-fat lifestyle with NO MENTION of sugar.
I admit that not everyone has the capacity or desire to understand how their bodies function, but everyone should at least be given the opportunity. Even health classes don’t give any justice to a truly proper diet. They make it sound as if you can eat as much of your favorite desert as you’d like, as long as you get your servings of fruits and vegetables, and DON’T EXCEED 2,000 CALORIES.
I can say for a fact that my base metabolic rate is around 2,500 Calories, and that is just the amount I need to SURVIVE with zero exercise while maintaining the same weight.
With the amount of exercise I do (1 hour a day, roughly), I need at least 3,000 Calories a day. Factor in my desire to gain muscle, and I need to eat as much as 4,000 Calories a day.
Education does nothing for people that have not opened themselves up to learning. People need to have a desire to read about it, learn about it, and change their lifestyles.
A large part of it is also parents and how they feed their children. I know kids who have been raised on hamburgers and cheap food, who now think that they can eat McDonalds for the rest of their lives because they haven’t gotten pudgy at the age of 17 or 18.
I also know kids who claim that cigarettes increase their metabolisms to the extent that they can eat significantly more. I think much hope is lost, and we’d frankly be better off with many of these idiots dying. If someone doesn’t respect his or her body to that great of a degree, I doubt the person’s capacity of respecting anyone else.
To finish off on a completely misanthropic and cynical note, some people really should not breath.
What are some nutrition myths to debunk for children? Making a quiz/measurement.
The link between saturated fats and heart health was based on faulty science & has been disproven. Dietary fat, whether saturated or not, is not a cause of obesity, heart disease, or any other chronic disease of civilization. Through their direct effects on insulin and blood sugar, refined carbohydrates, starches and sugars are the dietary cause of coronary heart disease and diabetes.
Plaque build up in the arteries are more attributable to carb consumption than dietary fats, which seems to be the conclusion of the following study. Carb consumption raises triglycerides & VLDL (bad cholesterol). Fats raise the HDL (good cholesterol). High triglyceride levels & low HDL levels are an indicator of plaque, glycation – the precursors to a heart attack and heart disease.
study from the Oxford group examining the postprandial (after-eating) effects of a low-fat vs. low-carbohydrate diet. (Roberts R et al, 2008)
Postprandial lipoproteins, you’d think, would be plentiful after ingesting a large quantity of fat, since fat must be absorbed via chylomicrons into the bloodstream. But it’s carbohydrates that figure most prominently in determining the pattern and magnitude of postprandial triglycerides and lipoproteins. Much of this effect develops by way of de novo lipogenesis, the generation of new lipoproteins like VLDL after carbohydrate ingestion.
Reasons to Eat More Saturated Fat
1) Improved cardiovascular risk factors
Saturated fat in the diet reduces the levels of lipoprotein (a) abbreviated Lp(a)—that correlates strongly with risk for heart disease. The only dietary means of lowering Lp(a) is eating saturated fat. Eating fats raises the level of HDL, the so-called good cholesterol.
2) Stronger bones
Saturated fat is required for calcium to be incorporated into bone – According to expert in human health, Mary Enig, Ph.D., as much as 50 percent of the fats in the diet should be saturated fats.
3) Improved liver health
Studies show that saturated fat encourages the liver cells to dump fat content. Saturated fat has been shown to protect the liver from the toxic insults of alcohol & medications and even to reverse the damage.
4) Healthy lungs
For proper function, the airspaces of the lungs have to be coated with a thin layer of lung surfactant. The fat content of lung surfactant is 100 percent saturated fatty acids. Replacement of these critical fats by other types of fat makes faulty surfactant & potentially causes breathing difficulties, collapse of the airspaces & respiratory distress.
5) Healthy brain
Your brain is mainly made of fat & cholesterol. Though highly unsaturated essential fatty acids found in cold-water fish (EPA & DHA) are important for brain & nerve function, most of the fatty acids in the brain are actually saturated. The brain needs saturated fats to function optimally.
6) Proper nerve signaling
Certain saturated fats, found in butter, lard, coconut oil, & palm oil, function directly as signaling messengers that influence the metabolism. Without the correct signals to tell the organs & glands what to do, the job gets done improperly.
7) Strong immune system
Saturated fats found in butter & coconut oil (myristic acid & lauric acid) play key roles in immune health. Loss of sufficient saturated fatty acids in the white blood cells hampers their ability to recognize & destroy foreign invaders, such as viruses, bacteria, & fungi. Myristic & lauric acid have potent germ-killing ability. We need dietary replenishment of them to keep the immune system vigilant against the development of cancerous cells & infectious invaders.
Saturated fats play many important biologic roles. They are an integral component of cell membranes, which are 50 percent saturated fat. Lung surfactant is composed entirely, when available, of one particular saturated fat, 16-carbon palmitic acid. Properly made with this fat, it prevents asthma and other breathing disorders. For nourishment, heart muscle cells prefer saturated long-chain palmitic and 18-carbon stearic acid over carbohydrates. Saturated fats are required for bone to assimilate calcium effectively. They help the liver clear out fat and provide protection from the adverse effects of alcohol and medications like acetaminophen. Medium-chain saturated fats in butter and coconut oil, 12-carbon lauric acid and 14-carbon myristic acid, play an important role in the immune system. They stabilize proteins that enable white blood cells to more effectively recognize and destroy invading viruses, bacteria, and fungi, and also fight tumors. Saturated fatty acids function as signaling messengers for hormone production, including insulin. And saturated fats signal satiety. Not surprisingly, given all these biological functions, saturated fats make up 54 percent of the fat in mother’s breast milk (monounsaturated fats are 39 percent; and polyunsaturated fats, a tiny 3 percent).
I hear a bunch of rumours like ballerinas stop having a menstruation cycle because they are so skinny. So I was wondering what are some good physical health benefits from being a ballerina and some bad physical health risks from being a ballerina?
Ballerinas face the same health risks as young female athletes when they don’t eat enough to offset the energy they spend, and stop menstruating as a consequence, says a new study.
The study, led by sports medicine researcher Anne Ho ch, D.O., at The Medical College of Wisconsin in Milwaukee, has been presented at the American College of Sports Medicine meeting in Seattle.
“These two components of the female athlete tetras put them at higher risk for the other two; the cardiovascular and bone density deficits of much older, postmenopausal women,” according to Dr. Ho ch, associate professor of orthopedic surgery and director of the Froedtert and the Medical College Women’s Sports Medicine Center.
The researchers studied 22 professional ballerinas, all members of the Milwaukee Ballet Company, to determine the prevalence of disordered eating, amenorrhea (lack of menstruation), abnormal vascular function and low bone density.
The dancers completed questionnaires on their menstrual patterns and eating habits, and underwent a blood test for hormonal levels. Thirty-six percent of the group had disordered eating habits and 77 percent were in a calorie deficit. Twenty-seven percent were currently amenorrheic, 23 percent had low bone mass density and nine percent were taking birth control.rterial ultrasound measurements revealed that 64 percent had abnormal artery dilation in response to blood flow.
“It was unknown if professional dancers without menstrual periods have evidence of vascular dysfunction, yet some characteristics of the tetrad were common in this group,” says Dr. Hoch.
“Eighty-six percent had one or more components, and fourteen percent had all four,” the expert added.
