Vitamin D, often called the “sunshine vitamin”, is a fat-soluble nutrient that plays a crucial role in our overall health. Unlike most vitamins, your body can actually make vitamin D when your skin is exposed to sunlight, specifically ultraviolet B (UVB) rays. Despite this natural advantage, vitamin D deficiency is extremely common. It affects people in regions with long winters, those who spend most of their time indoors, or anyone who has little direct skin exposure to sunlight. Worldwide, it’s estimated that around 1 billion people have either vitamin D deficiency or insufficiency.

When trying to eat healthier, you're often hit with advice like “balance your macros,” “eat more veg,” “cut down on sugar,” and “avoid processed foods.” It’s a lot, especially when life is already busy. What starts with good intentions can quickly become overwhelming and exhausting. That’s why meal planning is such a powerful starting point, and here, I provide some quick and easy steps to start a sustainable journey to healthier eating habits and getting organised.

Type “diet books” into Amazon and you’ll be flooded with thousands of results: low-carb, intermittent fasting, detox cleanses, and everything in between. But what’s the real deal?

And are they sustainable — or just another short-term fix? Here, I’m explain several different types of popular diets that include the Atkins, DASH, Glycemic Index, Mediterranean, Paleolithic, Ornish and Zone diets, and highlighting some key considerations if you are thinking of a specific diet.
