What are the benefits of citruses?

Citruses are plants that are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia.

Oranges and grapefruit contain too much sugar for keto, so we’re going to focus on lemons and limes. Citrus fruits have a lot of phytonutrients (healthy substances found in plants) and vitamins that are good for your body. For example, you get the whole vitamin C complex from a citrus, rather than just the ascorbic acid you would get from a synthetic vitamin C supplement.

How to consume them

Don’t fully depend on lemons and limes to get the vitamins and minerals you need. But they are a fantastic source of flavonoids (a type of phytonutrient beneficial for your body).

It’s important to keep in mind that when you consume sugar, you can’t absorb vitamin C. Smoking will also block vitamin C absorption.

What about grapefruits?

Grapefruit is high in vitamin C. It contains citric acid, which can help decrease the risk of kidney stones. It also has lycopene, which can be good for problems with the prostate.

However, there is a problem with grapefruit. There are enzymes in the liver that usually metabolize the majority of medications in the body. But, a certain chemical in grapefruit can inhibit this function, causing an elevated concentration and accumulation of medications. In fact, taking certain medications while consuming just one grapefruit or a 7 oz (a little over 200 g) glass of grapefruit juice could potentially lead to an overdose.

Grapefruit is also loaded with sugar. 1 cup of grapefruit is equal to 25 g of carbs and 1 g of sugar. Grapefruit is just not keto-friendly.

Where to get them

You can get citrus fruits in a regular grocery store.

You can get phytonutrient benefits from citrus fruit and the leaves, roots and flowers of lemon and lime trees.
