The Community Nutrition Forum (CNF) in Kerala organized a “Webinarathon” in celebration of National Nutrition Month in September. 15 days of 1 hour sessions conducted by expert dieticians and nutritionists about a range of topics such as basics of good nutrition, diet for different diseases and diet for different age groups.
I missed the first few sessions but since then have been listening to topics such as diet and nutrition for Alzheimer’s disease, women suffering from PCOS, lactating mothers and adolescent kids. One common factor has stood out in all the sessions. From children to elder people, every category of people has one basic requirement the lack of which is creating a host of health issues in them.
Vitamin D
Where do we get Vitamin D from? Simply go stand in the sun. But there is a catch. Our body creates maximum Vitamin D when exposed to early morning sun, between 7-9 am. This is why most Indian temples are open till 9:30 am. What happens after 9:30? Sun’s radiation becomes stronger as it gets hotter and we get exposed to more UV rays which in the long run can cause cancer. But simply standing in the sun is not enough.
With brisk walking we inhale more oxygen and the increased pumping of the heart sends oxygenated blood to all parts of the body triggering cell regeneration. More oxygenated blood flow rejuvenates the brain which in turn helps improve focus and concentration.
Many schools are adopting 10-15 minutes of workouts or yoga before beginning of classes every morning. Circumambulation of banyan trees is common in Indian temples because banyan trees produce the best oxygen in the morning. Most traditions are rooted in science but people would ignore if they are asked to walk for the sake of health but would walk readily in the name of Gods, so Gods have been used to build healthy communities for thousands of years.
The dominant genes in all of us contain genetic information from our ancestors who were active and predominantly outdoor people. Our present lifestyles are in direct contradiction with the information contained in our genetic makeup. Moreover, fats, proteins, carbohydrates, vitamins, sodium, potassium, magnesium, iron, etc all exist in a certain balance in our body. Imbalance in one of them can have ripple effect on the others.
Such imbalances result in the release of hormones that can do the exact opposite of the so called happy hormones, making people moody and pushing them into spirals of negative thoughts. This in turn reduces our body energy known as prana and when that battery dies we die.
Vitamin D manages a host of body functions and is even said to protect us from cancer. But we are too busy for morning walks. Many people take Vitamin D capsules, unknown to the fact that absorption of Vitamin D through the gut is very less compared to creation of Vitamin D from sunlight through our skin.
Then there are people deriding others for walking in the sun because it will make their complexion dark. Pitting staying healthy against looking white and (supposedly) good is not smart and is born out of ignorance of our own anatomy.
I have observed dietitians advising people to shun junk food completely and eat only healthy food. We resist just like animals when we are forced to change something we like or adopt something we don’t want to. People who like eating junk food, especially the ones in the adolescent age group are going to laugh off such advices. The question here is how did we reach the point of addiction to junk food?
Animals eat food for nutrition and not based on taste. When we see a pride of lions hunting and devouring a wild buffalo, there are two aspects to note. Herbivores extract proteins from the vegetation they eat but protein content is low in vegetation which is why they need to eat a lot to satisfy their protein needs and consequently developed large appetite and large physique. Carnivores eat herbivores to get the proteins from them.
Also, lions hunting a large animal means every member of the pride can eat to their full and they don’t need to eat again for some days. Hunting is an exhaustive and risky affair, zebra’s hind leg kicks have broken jaw bones of lions and starved them to death.
Our taste buds are far more in numbers and far more evolved than that of animals. Our preference for taste grew with time and this is how we started using spices. There were times when food was made with the balance of nutrition and taste, like the biryani. What changed those dynamics was the industrial revolution, concept of money and office jobs. Working for long hours became the norm and there was no time for sumptuous meals.
This heralded the emergence of a new food industry, the fast food industry. Food items that can be prepared quickly, are tasty and can be eaten fast or on the go became the need and the fast food industry catered perfectly to the new dietary requirements. A large proportion of fast food items are fried and deep fried, have milk products such as cheese and butter and adding a sedentary lifestyle with little to no exercise has become the recipe for health disasters.
Dietitians have to understand the short and long term adverse impact of eating junk food and prepare totally new diet charts with healthy food items that can reduce the adverse effects of junk food. Fast food has become an integral part of the global food industry and junk food an integral part of our diet.
Restaurants in India heat oil for deep frying a variety of vegetarian and non vegetarian food items in the same oil, reuse the same oil the next day and add fresh oil to it. Every food item fried in such oil is junk food for me. Dietitians have to accept this reality and evolve with their diet plans accordingly.
I have had problems digesting meat from my childhood so I never liked eating meat. My great grandfather was a Brahmin so I used to think my dislike to meat was genetic till my mom told me that she ate very less meat during her pregnancy. This is when I realized being not used to meat from my mother’s womb could be the primary reason.
My friends keep telling me the need to eat meat for meeting my protein requirements but I believe everybody’s nutrient requirements are different based on many factors and my body may not have similar protein requirements like others.
Precision nutrition is an evolving and exciting area of study where one’s DNA, microbiome, and metabolic response to specific foods or dietary patterns are analyzed and evaluated to determine the most effective eating plan to prevent or treat disease. According to many religions, each human being is made up of genes from 7 generations.
Considering 7 generations of genes on both father’s and mother’s side of each one of us, we are all made up of genetic soup and our genetic structure must be as unique as our fingerprints.
They say the way to someone’s heart is through their stomach. Healthy hearts are the key to our overall health and dieticians are best positioned to ensure this. The need for healthy diets are on the rise in every aspect of our lives so dietetics is an emerging field with immense potential. Looks like dietitians have a major role to play as we move towards our next stage of evolution.
