Why do people get hungry?

Whether you're trying to lose weight, build muscle, or even just maintain a healthy weight, your hunger is one of the biggest considerations. Here we investigate why we get hungry to help you understand your body's cravings better.

Lactose intolerance: everything you need to know!

The term ‘lactose intolerance' is thrown around so much these days, and sometimes you just want a straight answer as to what it is, and why it exists. We have those answers right here! 🐄

Understanding micronutrients

The World Health Organisation described micronutrients as the ‘magic wands' that enable the body to perform the chemical processes essential for proper growth and development. We all need vital vitamins and minerals. But for some people, differences in their DNA means they are less able to absorb or use specific micronutrients. If that's you, the good news is that by changing your diet, you can boost your levels, stay healthy and protect yourself from deficiency and disease.

Micronutrients: getting the vitamins and minerals you need

Eating a healthy balanced diet should ensure that the body gets all the vitamins and minerals it needs to function well. But our genetic make-up can affect our ability to absorb and use specific micronutrients. By adapting our diets and supplementing when necessary we can boost levels of the vitamins and minerals we need and optimize our health, fitness and sporting performance.

Best meat free protein sources

Switching to a vegetarian diet isn't easy and you might find yourself needing to do a lot of research into new foods you never considered before.

Are meal replacement shakes healthy?

By now, even if you haven't tried one, you should be well aware that there are shakes out there that are packed with all the nutrients of the whole foods you eat daily.

Is a low sodium diet good for everyone?

Sodium is a key component of many foods regularly consumed by people on a daily basis and although health recommendations often advise otherwise, there is still not enough done to stop people from adding excessive amount of salt to their foods.

Food that can reduce inflammation

Inflammation happens to everyone, it is part of our body's natural response to damaged tissues and also plays a role in the immune system response.

Gene in Focus: Part 4 - CYP1A2 (Caffeine)

The next gene we'll be looking at is CYP1A2. The enzyme produced by this gene is responsible for about 95% of all caffeine metabolisation in your body.

Gene in focus - Part 9: VDR (Vitamin D)

The next gene in our series is VDR; the vitamin D receptor gene. This gene plays a role in how well our bodies can utilise vitamin D, which in turn can affect various different processes. Currently, VDR appears in three different sections of our report - power/endurance, vitamin D needs, and caffeine sensitivity.
