nutrition genetics

Quick fact. Ready?
Not only do nutrients and immune defences get transferred to a child through breast milk, but also the microflora that exists in the mother’s GI tract. This includes both the good and bad bacteria that aid in breaking down the food that we eat.
Now that’s some amazing physiology right there! Could humans become anymore interesting?

It is amazing how much you can (IMO) improve a nutrition class without changing any content, just shifting the assumed sole focus off of effects on body weight!

Hi! You said that you are a personal trainer do you have any tips for cellulite. I have so much cellulite in my legs and I hate it. PLEASE help also I love your page and welcome back!

Cellulite is based on nutrition and genetics. Here’s the though, 90% of women over 20 have cellulite. Me at 90 pounds and me at 120 pounds - BOTH had cellulite. The model in the Cosmopolitan magazine - she probably has it. The toned and lean weight lifter in the gym - she probably has it. The amount of cellulite you have is NOT an indication of your athleticism. I struggle to wear shorts in the gym BUT I can do more pull ups than many of the men in there. 

Reduce your fat intake. STAY HYDRATED OMG THIS IS SO IMPORTANT. DRINK YO WATER GIRL. 

Things I do that have really helped (combined with going to the gym and being cautious of what I eat) 

1. Drink a glass of 1 tbsp of Apple Cider Vinegar (UNFILTERED/ORGANIC/MOTHER) and 8 ounces of water. DO NOT SHOT IT - it’s worse than vodka and zero buzz. I hate the taste so while some can do two glasses a day - I’m working my way through one. You can add lemon and honey - I added freshly squeezed orange this morning. 

2. Add Apple Cider Vinegar to your lotion and rub that shit on your skin twice a day. The scent will eventually fade. You wanna target it internally and externally.

3. Massage the affected area to increase circulation

Bone and skeleton distorted by osteomalacia

Literally translated, osteomalacia means “soft bones”, and in modern times very rarely leads to such extreme deformities as these.

There are many diseases and situations that lead to osteomalacia, but ultimately only one cause - defective bone mineralization leading to decreased or ceased deposition of new calcium or phosphorus in the bones. The condition itself is usually treated by administering high doses of vitamin D, while attempting to treat the underlying cause.

In children, osteomalacia is often called rickets. The adult form of the condition is often much milder than in children, but can still lead to bone weakness and bowing. In all ages, the most common cause is vitamin D deficiency, due to malabsorption by the intestines (as in Coeliac disease) , lack of sunlight, or very poor diet.

Vision & Microgravity...Can We See the Connection?

What do nutrition and genetics have in common? They could all be linked to vision problems experienced by some astronauts. We see people going up to space with perfect vision, but need glasses when the return home to Earth.

Why Does This Study Matter?

We want to be able to send astronauts to Mars, but losing vision capability along the way is a BIG problem. Discovering the cause and possible treatments or preventions will help us safely send astronauts deeper into space than ever before. 

It’s Like Solving a Mystery

We already have an idea of why vision changes occur, but the real mystery remains…why do some astronauts have these issues, and other’s don’t?

Now, let’s break it down:

Nutrition is more than just what you eat. It includes how those things work inside your body. The biochemistry behind how your muscles make energy, how your brain utilizes glucose and how vitamins help with biochemical functions…it’s all part of nutrition.

Genetics also play a part in the vision changes we’re seeing in space. Data shows that there are differences in blood chemistry between astronauts that had vision issues and those that did not. We found that individuals with vision issues had different blood chemistries even before their flight to space. That means that some astronauts could be predisposed to vision issues in space.

Just in January 2016, scientists discovered this possible link between genetics, nutrition and vision changes in astronauts. It makes it clear that the vision problem is WAY more complex than we initially thought. 

While we still don’t know exactly what is causing the vision issues, we are able to narrow down who to study, and refine our research. This will help find the cause, and hopefully lead to treatment and prevention of these problems.

Fluid Shifts

The weightless environment of space also causes fluid shifts to occur in the body. This normal shift of fluids to the upper body in space causes increased inter-cranial pressure which could be reducing visual capacity in astronauts. We are currently testing how this can be counteracted by returning fluids to the lower body using a “lower body negative pressure” suit, also known as Chibis.

Benefits on Earth

Research in this area has also suggested that there may be similarities between astronaut data and individuals with a clinical syndrome affecting 10-20% of women, known as polycystic ovary syndrome. Studying this group may provide a way to better understand vision and cardiovascular system effects, which could also advance treatment and prevention for both astronauts and humans on Earth with this disease.

Possible ways to cause genetic mutations (causing inhuman abilities) in a medieval (1100-1600) time period?

There are two types of mutations: spontaneous, which occur in utero, and are generally caused by a hormone imbalance in the mother or from inadequate nutrition; and genetic, which is passed down from the parents to the child. Neither of these cause superhuman abilities (unless you believe Stan Lee’s Superhumans), so your story’s probably going to be a fantasy, so you can say that it does.

You can also have some sort of fantastical beast that is either venomous, which would have to bite your character, or poisonous, which would have to be consumed by your character, and have that create strange abilities in them.

If you’re going for very realistic, then you could only have exaggerated human features, like increased speed or strength, that could be caused by or improved by training. There’s not any realistic way for a person to get inhuman abilities in any setting, unless you’re counting sci-fi and fantasy as realistic.
