The Importance of Healthy Eating

"What you put in is what you get out.” A famous saying we’ve all heard before. Maybe it’s time to take some time to understand exactly what this means.

Children don’t want to eat vegetables anymore. They’d rather have a burger and chips. And a nice cold Coke to wash it all down.
According to the Society for Neuroscience, recent studies reveal that diets with high levels of saturated fats actually impair learning and memory. Sadly these are the foods that are more affordable and readily available for kids in school cafeterias, people on the run and fits easily into busy schedules.

In addition to the saturated fat, many of these foods include white bread or other refined grains, fried foods and sugary foods and drinks which are all high in glucose. After such a meal the body sends all the energy to the digestive tract to process the food, causing the child to feel lethargic and having trouble concentrating in class. Other side effects include irritability, lack of mental performance and a regular diet of high glucose can result in damage to the kidneys, eyes, blood vessels and nerves.

A study done by Prof. Fernando Gómez-Pinilla of UCLA found that junk food reduces brain performance while commonly known healthy foods have numerous benefits. Omega 3 fatty acids (found in salmon, walnuts and kiwi fruit), for instance, improves learning ability and memory as well as help fight against certain mental disorders.

It is well known that child obesity is increasing, but the interessing part is that both over and underweight children may suffer from malnutrition. Unlike commonly thought that malnutrition only happens in developing countries with famine, malnutrition is not a lack of food, it is a lack of nutrients.
This means that children in first world countries can be malnourished if they don’t eat food with essential vitamins, minerals and nutirents, like vegetables, fresh fruits and proper meat.

This doesn’t mean that you have to look for vitamin enriched cereals next time you go to the store, this means you have to change the diet of your family, making sure everyone gets al least five portions of fruit and vegetables per day.

I was visiting family a while back and had some cereal for breakfast when I noticed the price was extremely cheap and only after examining the box I found the that best before date was 10 years earlier! The cereal tasted just fine.
The rule of thumb for food: if it doesn’t spoil, don’t eat it; but always eat it before it spoils.

You and your children need live foods, because “dead” food (those that lasts forever) have no nutrients and therefore doesn’t contribute to your body (except perhaps add some love handles). The body needs proper food in order to work and do what you expect of it.

Your children need a healthy diet, because they are growing and learning new things every day. If they are malnourished, their brains can’t work as they should and you will hear a lot of “I don’t want to go to school”, “I’ll do my homework later”, “I don’t want to study”.

Change your family’s lifestyle today. Eat healthy foods, find out how great fresh produce tastes and save fast foods for emergencies.

Teaching Good TV Habits

Extract from an article by kidshealth.org

Read full article: How TV Affects Your Child

Here are some practical ways to make TV-viewing more productive in your home:

·   Limit the number of TV-watching hours:
o  Stock the room in which you have your TV with plenty of other non-screen entertainment (books, kids' magazines, toys, puzzles, board games, etc.) to encourage kids to do something other than watch the tube.
o  Keep TVs out of bedrooms.
o  Turn the TV off during meals.
o  Don't allow kids to watch TV while doing homework.
o  Treat TV as a privilege to be earned — not a right. Establish and enforce family TV viewing rules, such as TV is allowed only after chores and homework are completed.

·   Try a weekday ban. Schoolwork, sports activities, and job responsibilities make it tough to find extra family time during the week. Record weekday shows or save TV time for weekends and you'll have more family togetherness time to spend on meals, games, physical activity, and reading during the week.

·   Set a good example by limiting your own TV viewing.

·   Check the TV listings and program reviews ahead of time for programs your family can watch together (i.e., developmentally appropriate and nonviolent programs that reinforce your family's values). Choose shows that foster interest and learning in hobbies and education (reading, science, etc.).

·   Preview programs before your kids watch them.

·   Come up with a family TV schedule that you all agree upon each week. Then, post the schedule in a visible area (e.g., on the refrigerator) so that everyone knows which programs are OK to watch and when. And make sure to turn off the TV when the "scheduled" program is over instead of channel surfing.

·   Watch TV together. If you can't sit through the whole program, at least watch the first few minutes to assess the tone and appropriateness, then check in throughout the show.

·   Talk to kids about what they see on TV and share your own beliefs and values. If something you don't approve of appears on the screen, you can turn off the TV, then use the opportunity to ask thought-provoking questions such as, "Do you think it was OK when those men got in that fight? What else could they have done? What would you have done?" Or, "What do you think about how those teenagers were acting at that party? Do you think what they were doing was wrong?"
If certain people or characters are mistreated or discriminated against, talk about why it's important to treat everyone fairly, despite their differences. You can use TV to explain confusing situations and express your feelings about difficult topics (sex, love, drugs, alcohol, smoking, work, behavior, family life).

·   Talk to other parents, your doctor, and teachers about their TV-watching policies and kid-friendly programs they'd recommend.

·   Offer fun alternatives to television. If your kids want to watch TV but you want to turn off the tube, suggest that you all play a board game, start a game of hide and seek, play outside, read, work on crafts or hobbies, or listen and dance to music. The possibilities for fun without the tube are endless — so turn off the TV and enjoy the quality time together.

ADHD Controversy

Hyperactive children can be unmanageable, defiant and aggressive. Many parents have their fingers in their hair, staring at this little creature and think: “This isn’t what I signed up for”. Children are supposed to be the ultimate joy in a parent’s life.

So what went wrong?

While it is true that some children need ADHD management and medication, the rate of misdiagnosis is staggering. Earlier research stated that about 2-3% of children, more boys than girls are affected by ADHD. Looking at reality, in a class of 30 kids about 5 or more are on medication which is about 16%, far more than the 2-3%.
Some people claim that ADHD can be better diagnosed and therefore more children are being picked up (research shows that 10% of children are now diagnosed), but I believe that the true reason is misdiagnosis.
How many mothers have you met who says: “Jason was diagnosed with ADHD when he was grade 1, but when I had him retested in grade 3, they said that he didn’t have ADHD.” I know quite a few mothers with the same problem. Children are being misdiagnosed and put on medication they don’t need.

Why are kids being misdiagnosed?

There are several reasons. One is that a teacher complains to a parent about their child being hyperactive, distant or short concentration span. Parents want their child to be the best, nicest and most beautiful, so such a report must be changed.
Another is that parents compare their kids to their friends’ and find that their child is naughtier or more defiant than their friends’ “little angels”, resulting in medical intervention.
There are many other people who regularly complain to parents on the behaviour of their kids - grandparents, friends, babysitters, etc.

The next step is to have the child tested by a professional who will find the child has or doesn’t have ADHD and take necessary action.
Misdiagnoses happen when normal children seem hyperactive.
Now you may think I’ve lost my mind, but there are a number of reasons why a normal child displays characteristics of hyperactivity or attention deficit.

1)      Children consume too much sugar and preservatives and too little nutritional food or drink.
Children need real nutrition for their brains and bodies to work properly. How much frozen, crumbled chicken or other shaped food do you serve your kids? They’re easy to make: just bake, pan fry or deep fry, they keep for ages in the freezer and kids love them.
Why you shouldn’t give your children food like this: they’re full of preservatives, salt, sugar, fat, ground up meat off cuts, and more. The amount of real nutrition in these is shocking.
Your children need to eat real meat: chicken, beef, fish and vegetables (not take-away cheesy veggie bites) and fruit. The fresher the food, the better the nutrition. Frozen veggies can be used, but fresh veggies tastes better and are actually better for your family.
Rule of thumb: if it doesn’t spoil, don’t eat it; but eat it before it spoils.

Here is a fantastic article written by Dr. Michael G. Conner (Psychologist) which explains how food and TV can make your perfectly normal child seem hyperactive, defiant or even mentally disturbed.

2)      Children need to drink enough water. This is actually part of the previous point, but it is too important to skim over. Kids love sweet drinks, soda and flavoured milk, but the fact is that the need water. You can treat them from time to time with their favourite drink or candy (not a bucket load of candy, just about one child’s handful), but they need to eat fruit and drink water daily and by default.
Your kids should know that the answer to: “Mommy, I’m thirsty,” is “Here’s a glass of water.”

3)      Children need involved, assertive parents. If you let your kids walk all over you, that’s exactly what they will do. Your house is not a democracy - you are in charge and your kids need to understand, from as early as possible, that your rules are the law.
I’m not going to go on and on about how to be a good parent. There are numerous books and articles out there to help you be a better parent. Still, even if you’ve read every single book and article on parenting, it is still your house and you have to be comfortable with your life.
Just make sure that the kids understand that the parents have to be obeyed and they can’t manipulate you. Make sure that your rules serve the purpose of loving and protecting your child and your choices have their best interest at heart.

Children disobey parents and teachers when they aren’t sure that they are loved and/or when they always get their way. The latter can make children become increasingly manipulative with parents, other people in authority and peers.

If you suspect that your child has ADHD, first eliminate external factors, like diet and parenting style, before you march off to the doctor.

The Anatomy of Stress

All of us experience stress on a daily basis. But do you know how it affects your brain?

Let me start by explaining what stress is.
The electrical circuit in your house has a fuse which is there to protect your appliances from an electrical surge. So, when lightning strikes your house, the fuse breaks and cuts off the electricity to your computer so that it won’t blow up.

Just like the electrical circuit in your house, your brain has “fuses” called synapses. The synapses are located between the brain cells (neurons) and the rest of your nervous system. Your heartbeat is like the electricity in a circuit. When it beats too fast, your synapses pull apart slightly, stopping the impulse from going through and possibly damage your brain and that is called stress.

The best way to monitor stress is to look at emotions. If you are happy, calm and content, your heart rate is normal. If you are frustrated or irritable, your heart rate is faster and when you are aggressive or enraged your heart rate is very high.

Stress (synapses pulling apart) always happens in your non-dominant brain hemisphere first, so if you are right brain dominant, your left brain will “shut down” when you are stressed. This also means that during stress you will find it difficult to perform tasks that are controlled by your non-dominant hemisphere. The more we stress, the less logical and more emotional we become.

fig.           row 1: top view          row 2: side view

Normal heart rate is around 60 - 75 beats per minute (bpm) (fig. A)
If you heart is beating at 80-120 bpm, one side of your brain shuts down. (fig.B) Notice how the synapses are slightly further apart.
At 120-180 bpm both your brain hemispheres (yellow part) will shut down (fig.C2)
**At over 180 bpm your limbic system (emotional brain; red part) can also shut down.
NB: Dehydration will also cause the synapses to pull apart. Drink enough water!

So, how do we get out of stress? The easiest and fastest way is to do some kind of physical movement. Take a walk, run around the block, do a few push-ups, do the dishes, etc. Slow, deep breathing also helps - remember the count-to-ten rule? Taking a break before responding to something stressful physically gives your brain time to "get back online" and then you can respond more rationally.

Basically your emotions should be able to tell you how much brain you have at any given time of the day and someone else’s emotions should tell you how much brain you’re talking to. Using this guideline you should be able to eliminate a lot of unnecessary conflicts.

**This happens very rarely, like in cases of road rage (smash someone's window) or blind rage where someone kills a person. This is where one can plead temporary insanity. That person had no logic nor emotion at that stage and was temporarily reduced to an “animal”.

Circadian Rhythm & Sleep

(Extracted from an article by Dr. Annette Lotter)

The pituitary gland control the excretion sleep and awake hormones namely serotonin (awake) and melatonin (sleep).

Sleep
 
Sleep is crucial to your central nervous system because of the amazing things that happen during sleep. This is when the body repairs itself, detoxifies itself, and replenishes its energy stores. Sleep is the one thing that humans have never been able to give up for any length of time. Everyone must have it on a regular basis. Many people with chronic conditions typically suffer from sleep disturbance, which slows down and hampers the body’s healing abilities.

Circadian Rhythm

The sleep/wake cycle is driven primarily by melatonin, the “sleep” hormone, and serotonin, the primary “awake” hormone.
Our bodies are basically designed to sleep when it’s dark and wake up when it’s light. But Thomas Edison changed all of this! And today, the average person in America gets exposure to effective sunlight only 21 minutes a day. 21 minutes is not enough for the body to receive the signals it needs to regulate its circadian rhythm from light.

Circadian Rhythm Disorder is usually involved in most sleep and mood disorders including depression, anxiety, bipolar disorder, seasonal affective disorder, insomnia, mood swings, premenstrual syndrome, elongated and irregular menstrual cycles, menopause, prenatal depression, postpartum depression, ADD/ADHD, and chronic fatigue syndrome.

Tips for restoring sleep:
·   Do NOT use supplements of L-theanine, tyrosine, tryptophan, or 5HTP in the evening. While this does go against the conventional wisdom, these substances actually raise serotonin levels—the “awake” hormones. This is particularly true of 5-HTP. These can be used during the day to make you feel more alert, but keep away from them at night.
·   Establish a rhythm where you go to sleep and wake up at close to the same time each day. This should include weekdays and weekends.
·   Sleep in as dark a room as possible. Total darkness is best.
·   Don’t drink much water after 8:00 p.m. This will limit your need to use the bathroom in the middle of the night.
·   Do stretching exercises before you go to bed.
·   Do not do strenuous exercise late at night.
·   If possible, take a hot bath or sauna in the evening.
·   If you are hypoglycemic or your adrenals are weak, eat a small, balanced snack before bed. Also, keep something healthy around, like almonds or pecans, to snack on if you wake up. Low blood sugar can keep you awake.
·      All meals should have a balance of proteins, carbohydrates, and fats. However, you should eat more protein in the morning and more carbohydrates in the evening. Carbohydrates tend to make you sleepy.

·      No colas or coffee, including decaf, at any time throughout the day.
·      Consider taking a “timed release” melatonin 30 to 60 minutes before you want to sleep. Timed release, also known as sustained release, is important because the half-life of melatonin is only 20 minutes. If the melatonin supplement is not a timed release, the melatonin will be “dumped” into the body all at once and it will be used up too quickly. Most people need the effect of melatonin to last several hours or more to gradually put them into a deep and restful sleep.
·      If you do wake up in the middle of the night and have trouble falling back to sleep on your own, this is the time to use non-timed release melatonin.
·   And when you wake up after a good night’s sleep, expose your eyes to sunlight as soon as possible. Sunlight helps you wake up and feel less groggy in the morning.
