An info graphic by Birmingham based catering company Ply vine Catering reveals the ten healthiest foods on the planet.Here are the foods:1. PotatoesOne potato holds 66 micrograms of folate. That’s about the equivalent to the amount found in a cup of spinach or broccoli. Kumara has almost eight times the amount of vitamin A required daily.2. LemonsJust one lemon has more than 100 per cent of your daily intake of vitamin C, which may help increase “good” HDL levels and strengthen bones. Citrus flavonoids found in lemons may help inhibit the growth of cancer cells and act as an anti-inflammatory.3. ChocolateJust seven grams of dark chocolate can reduce blood pressure in otherwise healthy individuals.4. WalnutsOf all nuts, walnuts contain the most omega-3, an essential fat shown to improve mood and fight cancer.5. BroccoliA medium stalk of broccoli contains more than 100 per cent of your daily vitamin K requirements and just under 200 per cent of your recommended daily vitamin C dose.6. GarlicAllicin is a compound found in garlic that works as an anti-inflammatory. It has been shown to help lower cholesterol and blood-pressure levels.7. AvocadosAvocados can reduce your risk of heart disease. In one avocado, more than half the fibre and 40 per cent of the folate you need daily can be found.
