5 things you probably didn't know about processed food

Evolution: Shaping Up Humans

Processed food has aided the evolution of Homo Sapiens: As food became easy to eat and digest, our jaws and teeth became less powerful and smaller.

The shape of our brains and even the development of language resulted partially from our eating habits in our evolutionary path.

Ultra-Processed Foods

Ultra-processed foods like white bread, cereal, chips, and wafers are remarkably common, convenient, affordable, extremely profitable for the makers, come in strong flavors and are aggressively marketed.

These 'ultra-processed' foods are low on essential nutrients while being high in sugar, salt and oils. The base ingredients which are used to 'engineer' these foods (cheap vegetable oils, sugar, flour) are already refined.

Our Everyday Foods

We consume ultra-processed foods every day without even realizing it.

  • The morning cereal and flavored yogurt.
  • The savory snacks and sweet baked goods.
  • The vegan hotdog and the chicken nuggets available on the street.
  • The doughnut or the premium protein bar we buy as a snack.
  • The carton-packed almond milk put in our coffee or the diet coke we have.
Apart from obesity, ultra-processed foods are responsible for depression, asthma, heart disease, gastrointestinal disorders, and even cancer.
More Light On Ultra-Processed Foods

Most cooked foods can be termed as 'processed foods', but ultra-processed foods are in a different domain, with few people having the clarity to differentiate.

A cooked carrot is processed food, but a bag of industrially-produced, carrot-flavored veggie puffs are ultra-processed and are still aimed at toddlers as a portion of natural food. Other examples include frozen peas or pasteurized milk.

Understanding how long food lasts
Understanding how long food lasts

Should humanity face a nuclear apocalypse of worldwide war, we need to understand which foods might be safe for survivors to eat, and how long the foods will last.

To understand this, we need to ask what makes food spoil.

Why foods go bad

Most foods spoil because of the growth of microbes. Preserving food is an attempt to limit microbial growth. Food can be preserved by drying, salting, chilling, or storing in air-tight containers.

  • Drying is the most effective because microbial growth is inhibited.
  • Salting is effective because it removes moisture, creating an environment where microbes cannot survive.
  • Sugar coating can prevent bacterial cells from functioning correctly.
  • Storing in air-tight containers is less effective because there are probably a lot of microbes on the food before you put it in the container. Some microbes are anaerobic, meaning they don't need oxygen.
Food preservatives

Preservatives are used in foods to extend their shelf lives. One of McDonald's Big Mac in Iceland is an example of a long-lasting processed food. It has been on display since 2009, in a glass box. Preservatives that has been discontinued by McDonald's are:

  • calcium propionate that prevents mold growth on bread.
  • sorbic acid that also inhibits mold from cheese
  • sodium benzoate, which inhibits the growth of bacteria in the Big Mac special sauce.
The Paleo Diet

The Paleo Diet is an effort to go back to eating how we’re biologically designed to eat, allowing us to tap into our genetic potential and start living healthier immediately.

Lose weight on the Paleo Diet
  1. Eat fewer calories than you burn every day.
  2. Eat mostly real food if you want to be healthy.
  3. Do those two things consistently for a decade to KEEP the weight off.

When you only eat real food and avoid all unhealthy food, you’re more likely than not going to run a caloric deficit – and thus lose weight.

Eat the following:
  • Meat – GRASS-FED, not grain-fed. 
  • Fowl – Chicken, duck, hen, turkey.
  • Fish – Wild fish, as mercury and other toxins can be an issue in farmed fish
  • Eggs – Omega-3 enriched cage free eggs.
  • Vegetables – As long as they’re not deep-fried, eat as many as you want.
  • Oils – Olive oil, coconut oil, avocado oil – think natural.
  • Fruits – Fruits have natural sugar, and can be higher in calories, so limit if you’re trying to lose weight.
  • Nuts – High in calories, so they’re good for a snack only.
  • Tubers – Sweet potatoes and yams. Higher in calories and carbs.
