Think of love as 'a nutritionally balanced diet' – here's how to make your relationship last, according to science
Spoiler: it takes more than one love language
It takes more than one love language to maintain a happy relationship, according to a new study. Here's why a 'balanced diet' is the secret to long-lasting love...
Valentine's Day is just around the corner, and for busy parents, it might be the excuse you need to set aside some couple time. For some, that might look like spicing up the relationship and trying something new – like tantric sex – while others might use it as an opportunity to revisit their love language.
In case you're out of the loop, love languages are the five different ways of expressing and receiving love: words of affirmation, acts of service, receiving gifts, quality time and physical touch. The concept was created by Gary Chapman, author of the book The Five Love Languages: The Secret to Love That Lasts, and he theorised that every person had a preferred love language. Understanding your partner's love language is widely thought to be one of the keys to a happy, long-lasting relationship.
However, a new study published in the Current Directions in Psychological Science suggests that long-term love isn't quite so straightforward. The authors of the research evaluated existing research on love languages and found that most people need to use and feel a mix of all five in order to cultivate long-lasting love.
They offer an alternative metaphor, describing love as a 'balanced diet'. The researchers write: "The process of maintaining successful, loving relationships is akin to keeping a healthy, balanced diet. Whereas Chapman’s language metaphor implies that people can feel love only when their partner speaks their love language, the healthy-diet metaphor suggests that people need multiple essential nutrients to maintain satisfying relationships."
However, that doesn't mean you should disregard the love languages theory entirely, as the researchers explain: "This does not mean that all expressions of love will be equally important to all people and in all situations. Just as there are times when people might have particularly strong needs for certain nutrients (e.g., a marathon runner needs extra carbs), people might benefit more from specific expressions of love at certain times, such as physical affection during times of stress."
They add, "Relationship science has shown that people with chronic relationship insecurities, for example, people higher in attachment avoidance who tend to have issues trusting in their partner’s love and care, experience even greater benefits when their partner expresses appreciation."

Relationship rubrics and categories like the love languages theory are a comforting and easily understood way to simplify something that is actually pretty complex and – as parents will know more than most – not always easy to maintain.
It's likely for this reason that Chapman's theory of the five love languages is so popular – The 5 Love Languages has sold over 20 million copies worldwide and been translated into 50 languages since first publication, and the hashtag #lovelanguages on TikTok has more than 500 billion views.
Unfortunately, relationship fixes are rarely so straightforward – though this probably won't come as a surprise. Sure, if you and your partner are busy parents who don't have enough time in the day to do anything for yourselves, then acts of service probably go a long way. But next time your loved one is feeling down about the way they handled that toddler tantrum, try a few words of affirmation instead.
As the study explains, "Successful relationships require that partners have a comprehensive understanding of one another’s needs and put in the effort to respond to [them]".
